Full Grain Fill Finish produced with Pinnacle Polyester and Pinnacle Polyurethane

The subject of how to get that full grain filled high gloss / high polished look without over building a lacquer to the point that it cracks has come up from time to time. I recently had a customer who builds and finishes custom walnut tables to a mirror finish that are gorgeous beyond belief have a serious fracturing issue. He had been building up pre-catalyzed lacquer beyond what the manufacture recommended. While this had worked well in the short term, cracks and fracturing of the finish began showing up after a few months.

The best solution I have found for this problem is the use of polyester sanding sealer. This is a great system however it is not something that should be attempted by someone new to the business of furniture finishing as there are three components to mix and if not done right will never dry. Eight to twelve mils of this material may be applied in one application to fill wood grain and or pores and it won’t crack and fracture like lacquers and conversion varnishes do. This is the finish used on pianos.  Once you have applied enough polyester sanding sealer to fill the wood grain and pores you can then block sand it smooth and flat. You can then go straight to final sanding and polish if you wish. This would provide the hardest most durable finish. However, polyester does turn yellow over time. An alternative is to top coat the polyester with non yellowing lacquer or high grade two part polyurethane like the Pinnacle brand we have sold for years now. This polyurethane has UV inhibitors added to it to slow the effects of yellowing that are typical of polyurethanes.

Thomas Craven has been a finisher in the valley for many years and has consistently produced excellent products. He and his team have mastered the Polyester/ Polyurethane finish as you can see in this video.  You can reach Thomas Craven through his web site at:  http://www.TCWoodFinishers.com

CI Centurion Acrylic lacquer in action

I have been reporting on the acrylic lacquer for the last few years yet few of the die-hard finishers have taken up the new technology, for better or worse in our industry getting up and running with a new product, water-based materials or other wise is a trying activity experimenting with you customers kitchens is a risky business and with economic conditions as they are these aren’t the times to venture away from the norm, or are they?

Having a technologically superior product that is easy to apply could be the thing that would put you ahead of the crowd could be the ticket to your survival in this cut throat market.

The Church of Scientology has been on a project to up grade and renovate their various facilities around the country. After extensive testing they decided on using the Centurion acrylic Lacquer from CIC  Coatings they needed something that was commercial grade tough and as well crystal clear which wouldn’t yellow. As well they wanted a product that was as environmentally friendly. The CIC Acrylic lacquer met all these qualities It doesn’t yellow as it is not nitro-cellulous, it’s as hard as a pre-Catalysed lacquer yet it has the moisture resistance of a urethane, it is low VOC and has a relatively low odor.

The Finishing contractor, Jody Toole, of Jody tools Finishing (http://www.jodytoole.com/) has been applying the product with an Kremlin Air assisted Airless spray rig has been over joyed at the results he has been getting.

the following are a few pictures of  one of the recent  Church of Scientology churches which have been renovated using the CIC Acrylic lacquer.

Thinning and retarding water based lacquers and coatings

There are a few tips to thinning and retarding water based materials that are common to most all of the water based materials on the market today, knowing these tips can make spraying out water base materials easy fun and most importantly give you the control over the flow of the materials so you  compensate for the varying conditions of your environment.

One of the things to be aware of with water based materials is that they are temperature and humidity sensitive, meaning that on a cold and rainy day it will take forever to dry if left wit out forced air and some heat.

The obvious and wonderful characteristic about water based materials is that you can thin them with water; water is cheap and not explosive.  No one has ever accidentally blown up their shop with a bucket of water.  That being said   you can overthin with water and that can create a mess.

Before we get into percentages and how much you should thin, one thing you should know is that the warmer the materials are, the thinner they will be. This is true of both water base and solvent materials.   Heating pads, bucket heaters and in line material heaters are all things that you can implement.  Inline materials heaters are pricey and not something that are too common here in Southern California  but can be used. More commonly and more practically you can just keep your buckets off the concrete floor or move the bucket in to the office of the shop overnight if it’s cold out. Warming up water base is easier and safer than warming up the solvent materials and in fact with some water base materials you can even warm  them up in the microwave machine, a little impractical but not impossible.  For every 10 degrees you heat the material you will reduce the Viscosity by 10% .  And that is a good thing to know because you can reduce your labor by putting on a thicker coat save our self the labor of having to put on another one of or two more sometimes

Now onto the more practical, the first thing that you should do is adjust your equipment to the material in other words if you have been spraying lacquer with an extra fine airless it’s probably going to be too small an orifice for the water base; you don’t want to overthin it so that you can get it out of  your gun but rather get a bigger tip. Generally a 1.7 mm tip in a cup gun and or something no smaller than a .014 in an airless and that would be the smallest I recommend 1.8 or a 2.0mm tip and needle for a cup or gravity gun.

When you do need to thin the materials down I start out with about 5% water and see how it’s coming out of the gun and laying down, with water based a good heavy coat is what you want if it looks a little blue you are doing good. You want it heavy enough to flow out but obviously not so heavy that  it is running.

Ok the next thing is getting it to flow out and lay down smoothly if it has any orange peel to it then you need some retarder. I generally add the retarder whether I need it or not as I like that fact that it flows out better, this might not be true of all water bases but the ones I have used it just seems to work better with the proper amount  of retarder.

Glycol ether is the solvent for retarding water based material you can also use that for retarding regular solvent lacquers   If you use too much your coating will never dry. The other thing to know is that you can add the retarder too fast and “shock” the material. Shocking information, but true. Dump the retarder directly in to your pot and it can cause itto foam up and have an adverse reaction. Some chemicals go together easily and some don’t;  then there are others that are right on the boarder, this in one of those. So the best way to add the retarder is to mix it 50/ 50 with water first and then add that into the water based lacquer while stirring it. Start out with one to two percent of the   50/50 water retarder solution and see if that doesn’t do the trick for you.  You can go as high as about 4%. If you are working with pigmented water base materials then you can go up to 7% .

White and pigmented lacquers require more and will have a tendency to “mud Crack” (Mud cracking is the phenomena whereas the material dries it begins to crack like mud drying out)   if you don’t use the retarder, what is happening is the solvents are drying out of the pigment faster than the pigment is drying and so you need to slow the process down so that they all dry and flow together.

Not all retarders are the same, some companies sell retarders that are a combination of different things, these work well for solvent lacquers but not always for water based materials.  You either want a lacquer retarder that is made and marked for Water based materials OR you have to test them. The way  you test your normal run of the mill retarder to see if it will work in your waterbased system is to mix it  with water. Simple, if it mixes in you’re good If it separates and doesn’t mix in or foams up and looks weird then its not going to work.  There are a few manufactures that have acetone in their retarder which doesn’t mix well with water If you add that to your water based lacquer its trash.

Ok I hope this information is clear and to the point. Use it and let me know what you get. Leave comments on the blog posting for others to see. I have specifically kept this report completely generic so that if you have a product that you are trying out for the first time it is generally best to contact the manufacture and ask them what they recommend, the better companies will spend the time to answer your questions others won’t

Tips for Spraying out the CIC Centurion Conversion Varnish

I have been using the CIC conversion varnish now for over a year and have been very impressed with both the product and the manufacture. There are a few things to know about this product that I have come to learn over the course of the last year of handling the material that I wanted to pass along. One of the values of this Blog is that I can document the things I have to tell people over and over, I’m sure that I’ll continue to go into shops and explain the same thing to people but it helps that I can refer people to an article on the matter.

 The Centurion Water based conversion varnish is a water based product that can be thinned with water (imagine that!). As with any coating product you can over thin the material. There are essentially 4 things in a coating: resins, binders, solvents, and pigment (color). The resin is the paint itself; the binders are the chemicals that hold all the various parts together, the glue if you will. The solvents are the chemicals that keep the paint liquid until you apply it. Once you have applied the paint, the solvents evaporate leaving a hard coat of paint. Colorants do just that add the color, different paints require different colorants or pigments,

 So now, all these things work together, the various components of a coating have different chemical properties and different tolerances. You can only put so much pigment in a clear lacquer before you have gone too far and your final product will be chalky and flat or might not stick because there is too much of the dye powder and not enough of the binder to hold it all together. The same goes with solvents you can thin down a lacquer with lacquer thinner to a point where there is not enough binder and the chemicals no longer work together. Think of a bag of concrete add a little water and you have a drive way, too much water and you have a mud pit.

 Ok the basic theory now being covered, you thin the CIC Centurion water based conversion coating with water, no more than 20 % and that is pushing the limits. Generally you thin a coating so that it will spray or roll out well if you have to thin it further than that you are using the wrong equipment and most likely need to get a larger tip size for you spay gun. (see the article form Thomas Craven on spray techniques elsewhere in this Blog)

 Here is a picture of what can occur when you over thin the water based Conversion varnish (or any water based product for that matter)

An orange peel so bad you don’t know what you are looking at. What has happened here is that there is too much water and so the binders can hold it all together. This project had to be stripped down and re-done.

FYI, sometimes the material comes to you in the can and it is very thick and has to be thinned down.  Ok that’s is something that you would expect to have to do and here is how you do it:

1.   The first thing you have to do is have the right equipment, if you are trying to spray a water based product with a small tip size then you will be forced to over thin the material to get it out of the gun. Your regular lacquer and automotive gun is usually a 1.4mm which is too small.  I have use a 1.7 mm tip in an HVLP cup gun with success but prefer to use a 2.0 mm. The Centurion works great out of an airless or better yet the air assisted airless, don’t use the extra fine tip as you might “Sheer” the material (a term use to describe what happens when the material is subjected to too much pressure) your finish will come out grainy as if you had fine sand al through your material. 

 2. The next thing to do is make sure that you material is not cold, the warmer the material is the more fluid or less viscous it will be factually for every 10 degrees warmer your lacquer (water based or solvent ) will be 10% thinner.

That mean that if you leave a bucket on the concrete floor of your shop and overnight it cools the material down to 50 degrees, you can make it 20% thinner by warming it up to 70 degrees.  Now you can reduce your labor by warming your materials as you won’t over thin the stuff and have to put on more coats to make up for all the thinner that is going to evaporate on you. you would also be saving money on thinners as well. if you are using water based materials, water is cheap Labor however is not.  

With water based materials you can actually put them in the micro wave and warm them up this is not a practical thing. Keeping the buckets off the concrete is one step. Pulling your cans in to the office overnight is another, generally the office is climate controlled. Grainger’s sells bucket heaters that belt around a 5 gallon pail, others have wrapped a heating blanket around a pail. Warm it up, no hotter than about 90 degrees. ( if you have decided to apply this principle to a solvent base material don’t blow yourself up with a jury rigged heater)

3. Sill a little lumpy with your gun spitting material instead of laying on and even coating… thin it another 5%.

4. If it  is still lumpy and or not flowing out at this point it to add a small amount of retarder. Here is an example of that scenario this is a Centurion Conversion varnish that has been tinted Brown, with the all the Pigment the materials are not flowing out.

 

Looks pretty crappy: what solved this was adding lacquer retarder. A mixture of 50/50 water and glycol either EB: Lacquer retarder.

I use to say that you could use any ol’ lacquer retarder, that however is not the case. Lacquer retarders like Margaritas are not all made the same. The Valspar Lacquer retarder when mixed with water foams up and turn into a clear solution, there are chemicals possibly acetone in there mix that do not mix well with water, that’s not to say that it is a poor retarder for lacquer.  Some companies make water based lacquer retarders

If you get the MSDS and it say the primary ingredient is glycol either EB then you are set. A.G. Layne, Sunny side, CIC and other manufactures have retarders that are primarily Glycol EB, Any retarder when mixed 50/50 with water and goes into solution will work.  

5. You mix the lacquer retarder 50/50 with water and then add no more than 5% of that to your centurion conversion varnish. The more you add the longer its is going to take to dry. When you mix this up make sure that it has gone into solution before you add it to your material, and when you do add it stir the conversion varnish while adding it slowly. Dump it in too quickly and you can “Shock” the material. Meaning that the two materials will react against each other and separate  

 In the first picture above, the walnut the job. The containers of conversion varnish that has been over thinned were allowed to thicken up by letting some of the excess water evaporate off and then they were retarded with the above mentioned 50/50 mix of water and retarder and the job came out fine.  

If done correctly you’ll have a rock hard finish that is as smooth as a good nitrocellulose lacquer finish.     

Ok, That’s my story and I’m sticking to it of you have questions feel free to send me a line.

Sucess story using the Rexcell water based conversion varnish

Walnut Kitchen Island finished with W/B Conversion Varnish

 This is a story from  a gentleman who is a retired air force officer whose hobby is cabinet and furniture building, As you’ll see he is an incredible cabinet builder.

 As his shop is in his garage with limmetted space and no spray booth Dennis was interested in water born products but needed something that was super tough. I suggested the Rexcell  Water based Conversion varnish. As you will see it turn out stunningly beautiful.

Fore note: this product is no longer manufactured by Rexcell but is now being manufactured to spec by another American manufacturing company, the product is as good or better than before, It has been referred to as three different manufactures Renner, Rexcell and now CIC. It is all the same product, a water born Conversion Varnish.

Here’s is the Story Dirrect from Dennis : 

FIRST EXPERIENCE WITH WATER BASED FINISH

 I have been building wooden furniture and cabinets as a hobbyist for over forty years. Over this period I have sprayed, brushed and wiped on all the standard finishes that hobbyist woodworkers usually use. Because I’m in my upper sixties in age, I have looked upon the new water based finishes for wood with skepticism. I recently finished a kitchen island for my daughter’s new kitchen. It’s a walnut cabinet with a maple butcher block top. It measures 50 inches long by 30 inches wide by 36 inches high. And, I sprayed a water based conversion coating (called water based lacquer) for the protective finish. This was my first experience with a water based coating and I’m extremely pleased with the way it turned out. I chose it for it’s touted durability which was demonstrated to me by Greg Saunders, a sales representative for the Annex Company of Reseda, California. Greg showed me samples, coated with the product I used, that he placed in his home shower for approximately two months and the durability was impressive. ( You can see this test in another post on the Blog)

 The material I used is made by the Rexcel Company, and is a water based conversion varnish, meaning that it is tough enough for counter tops and moisture resistant for high moisture areas)

I used a Goldenstar HVLP air spray gun (Advertised as being especially for water based finishes)

( This is an inexpensive but quality spray gun that Annex paint sells)

Fluid orifice: 1.7mm (this size is recommended for this water based product)

Pressure required: 15-50 psi (I used 30 psi)

 I was spraying in 90 degree summer weather and therefore added 3 percent of regular lacquer retarder. Greg, the sales rep, said I could thin the product with water by about 10 percent but I used it full strength and it seemed to spray very well. I am used to spraying regular nitro cellulose lacquer and I used the very same technique with this water based lacquer. It appears milky in color when it first goes on but otherwise it sprays on like regular lacquer. You have to use the same caution on vertical surfaces as with regular lacquer. A good technique is to use a big piece of brown cardboard to adjust your spray volume and pattern before tackling your project.

 I sprayed three coats and sanded lightly between coats. I probably could have gotten by with only two coats. Remember, each coat of this water based finish lies on top of the previous coat. It doesn’t melt into the previous coat as with regular lacquer. As with regular lacquer, this product dries quickly and can be sanded within 20 minutes and recoated. It was hot and dry when I sprayed so weather conditions might alter the drying times. After the third coat, it was a bit too glossy for my preference so I waxed with a steel wool pad which resulted in a soft sheen that I was looking for. I’m totally happy with the way it turned out.

 I kept a bucket of water and a rag nearby while I was spraying. A couple of times when I got runs, I immediately wiped it off, let it dry, sanded lightly, and recoated. I really enjoyed the water clean up – of the runs and the clean-up of the spray equipment. A word here about clean-up – and this attests to the durability — if you wait until this finish dries, you can’t clean up with water – it takes acetone. I sprayed the first coat with my regular glasses on (plastic lenses). I got overspray on my glasses and I still haven’t gotten it off. However, acetone on my plastic lenses would probably not be smart.

 I made a silverware tray at the last-minute for one of the cabinet drawers and I brushed on two coats of finish with a foam brush. That went on very nicely too. Will I continue to use water based finishes? — definitely yes, especially for kitchen and bathroom furniture. Will I use it for living room furniture? – the jury is out, but I’m hoping to.   

Here is another picture of Dennis’ work. For note this stunningly beautiful Kitchen Island was built by Dennis for his daughter who recently returned from active service in the Military in Iraq.

Renner Acrylic lacquer -Tips for scuccess

 

This is a brief write-up from a finisher who has been successfuly using the Renner Low VOC Acrylic Lacquer

Dear Greg,

 As you requested I’m giving you a little write up on the Renner Low VOC Acrylic lacquer from that you have been supplying to me.

 I have been using the Renner Lacquer and really like this product.

 I wanted to detail some of the basic procedural points I employ when using this product that may help other people who use it:

  

  • I generally only need 2-3 coats of the Renner to get a beautiful finish. 2 coats are most common if you don’t thin the product. The product does not need to be thinned. I have thinned the Renner Acrylic lacquer but only on the final coat if you don’t wish to have any further build up than what I already have on the piece I am spraying. You shouldn’t this this any  more than about 5% per manufacture’s specs any way.

 

  • The key to spraying a good finish is having your gun set properly based on your spraying conditions ( mainly temperature and size and shape of the item you are spraying .) I generally have the PSI on my gun set between 20-40 no more than 40 psi. Then watch your spray in reflected light as you are spraying to ensure you have a wet coat over your whole job.

 

  • I have found that the Flattening agent in the Renner Lacquer tends to settle rapidly to the bottom of the can or spray gun. I have picked up a gun that I had sitting with the renner Acrylic lacquer in it for a few hours and sprayed it and the first thing that comes out is the white flattening past that has settled to the bottom of the cup. A light sand and then re-spray with the same product handled that for me. I have also had spots of white spit out of the gun these are just the flattening past that settled. You have to let the lacquer dry and then sand then off and re- shoot it. The over all handling is to stir and strain the materials well and then don’t let your gun sit for too long. If you use a pot system then stir the pot regularly. Shaking the materials well before you use them is also a good Idea. The flattening past goes back into solution very easily.  

 

  • I always test spray something before I lay on a coat and especially the final coat; I want toknow that the gun and materials are all dialed in before lay the materials on the final coat.

 

Hope this is helpful.

Tia D

 Tia has worked in a custom mill that produces a wide Varity of custom mill work that has been shipped and installed around the world. She has been applying high end finishes for about 4 years and is one of the best and most detail oriented people in the trade. I asked here for this little write up to help other customers with this product.  

  In addition to Tia’s Tips I wanted to add a few other characteristics about this material that I have found about it.

  •  This is an acrylic lacquer, the qualities of it are that it doesn’t yellow and it is nearly as hard as a Catalyzed lacquer, however, you can’t mix it with regular nitrocellulose lacquers. You have to keep these materials separate and do not mix them.
  •  You also don’t want to use this material over another lacquer it is self sealing and is used with it’s self spray in a light coat and lat that flash off and then your following coats to the desired build. You can glaze between coats.

 

If you have questions or comments send me a line I’m always interested in hearing what people are running in to.

 Best,

Acrylic Lacquer: A new, low voc clear coating for wood.

    No two finishing lines are exactly the same. Nor are the finishing standards or production goals identical from facility to facility  or shop to shop. To satisfy a wide range of variables relating to application, curing, finish durability, appearance, environmental requirements, “green” sustainability initiatives, and cost, I have been on a constant search for the different coatings out in the market.  To this end we have brought in yet another product for our customers to use.

 

   First of for those who may not be  familure with some of the other products that are generally use in the world of finishing to day.

 

   Nitro cellulose Lacquer, the basics.


Nitrocellulose lacquer is made by mixing fast-drying solvents generally know as lacquer thinners with wood and cotton pulp containing cellulose that has been broken down by acids. A chemist working for the DuPont Chemical Company, is credited for inventing nitrocellulose lacquer in 1921. It was quickly picked up by Henry Ford for his mass-produced automobiles because finished cars could come off the assembly line faster. Not long afterward, nitrocellulose lacquer replaced shellac and oil-based varnishes and became the preferred finish and the industry standard for furniture and cabinet manufacturers.
: nitrocellulose lacquer is relatively inexpensive and dries quickly. The cured resins provide a reasonable protective layer of film over the wood. After the hard film cures, it rubs out well and provides it signature  smooth and silky surface that, Also, because it is an evaporative finish, each new coat of lacquer blends into all the previous coats, making it easy to repair.

The benefits for large and small production shops are considerable

The disadvantages to using nitrocellulose lacquer are also notable. The film yellows as it ages, and it can eventually shrink to the point of causing cracks (often called crazing) to form in the surface. Generally this occurs when you have over built the coating. As well, it does not hold up well in moisture i.e. your kitchen and bathroom.  Best results fore application are by spraying it on; but the overspray is highly flammable. (The same ingredients that go into nitrocellulose lacquers are also used in the manufacture of some explosives.)

Because it dries so quickly, when applied under conditions of high humidity, the lacquer film can trap condensed moisture and cause the finish film to appear cloudy — a problem referred to as blushing. You can overcome that finishing obstacle by adding a slower-drying thinner, called a retarder, which allows the moisture to escape before it gets trapped in the film.

 

  The need for something that doesn’t yellow and has a greater moisture tolerance.

 

Acrylic lacquer

 

  With the increased popularity of using unstained, light-colored woods (such as ash, birch, and maple), woodworkers and furniture manufacturers wanted to avoid the yellowing problems associated with nitrocellulose lacquer as it ages. The finishing industry responded by developing lacquers containing acrylic resins that are truly “water-white.” Acrylic resins go on crystal-clear and stay that way over time. The most widely used of these products is called CAB-acrylic lacquer, made with cellulose acetate butyrate and acrylic resins.: it is best applied by spray equipment, diluted with regular lacquer thinner to obtain the ideal spraying viscosity, and it is fast-drying. Acrylic lacquer is often used as a protective topcoat over colored pigment lacquers to make them wear better and to enhance their resistance to scratches.

Acrylic lacquer dries to a less brittle and more flexible film than that of nitrocellulose lacquer. It is also more expensive. Otherwise, the working properties are much the same

 

The acrylic Lacquer I like:

 

Renner the Italian wood coating manufacture has long provided me with exceptional water based products wanted to get into the American nitro cellulous lacquer market and released their “JL” series 161 VOC acrylic lacquer. Why they had to go and name it like that is beyond me, I would have preferred a snazzy marketing name that I could refer to it as, but, oh well.

 

Here are the qualities of this product:

 

Low VOC, more environmentally friendly and you can reduce it and still be compliant; a word of caution though, over thinning it has caused problems. Suggested total amount you thin it is not more than 5%.

 

Low Odor, It does have a smell but it’s not half as bad as other products.

 

Self Sealing, You don’t need a different product to seal this with. Best practice is to lay down two thin coat and then sand it as if it were a sanding sealer.

 

Non-Yellowing, what else do you say this doesn’t yellow as any regular lacquer or Pre catalyzed lacquer will.

 

Dies Quickly and Hard, I have had a hard time digging my nails in to this stuff, so it is almost as hard as a pre-cat if not harder. As well the acrylic is much more UV resistant,

 

18% Solids, this is a term that a lot of people don’t get but is a very important datum when evaluating a coating. Basically it’s thicker and so you get more square foot coverage. For reference the most common lacquer on the market is 11% solids it’s cheaper but you have to spray twice as much. For most shops there labor is more costly than there materials and so the few buck you save on materials ultimately cost you more in the long run.  

 

 

Cautions I have found:

 

Don’t over thin it. With a lacquer thinner, you can thin it 5 or 10% but not beyond that it will blush and do strange things. In essence when you thin some materials you are trying to increase the viscosity and make it come out of your spray gun better. If you over thin it you begin to alter the chemical make up and that is where you get into problems.

 

Don’t apply it over another manufactures sealer. A, you don’t need to use a sealer and B, the acrylics are not compatible with the lacquers when you do this the nitro-cellulous  in the earlier coating get re-wetted and then reacts with the acrylic resins and does weird stuff.

 

I now have several large manufactures using this product and having great successes with it.

 

If you are interested in this product give me a call if you have had successes or failure with this product I would like to know about them. One of the things I have learned in this business is that you test always. The greatest test of a coating is the test of time. How long did it last and where?

 

Best,

 

Greg

Annex Paint is bringing in Ultra Woodcoating

The New Ultra Master series compliant Laquer

The New Ultra Master series compliant Laquer

 

 

Ultra Wood Coatings is a new company that has taken over the old American Wood finishing production plant in down town LA.  They have some  really nice products that we are bringing in.  I’ll tell you about the products but first let me tell you about the Company. There are three principles in the  company, all of whom  I was very impressed with, they are Professionals and Chemists  with a passion to doing things better  more efficient  and to a higher standard, the Third member of the Trio is  a former R and D Chemist of Valspar  who has recently come out of retirement after completing  his 7 year non-compete obligation with Valspar.

This chemist had now formulated line of products that have Higher volume solids ( that means you can cover more square  footage with the comparable amount)  and is very fast drying.

I have sprayed  out the 275 water white and it has passed me expectations. It dries quickly and doesn’t have the same tendency to blush as does the Valspar. You of course can thin and retard it as you need to.

One of my bigger complaints with Valspar was that it was so thin that you had to layer on 10 coats to get a decent coverage.  The other thing that I didn’t like about Valspar was it’s tendency to yellow. that’s why I switched  out main brand to Simpson. Simpson was and had been a  good lacquer but they have been consistently un-able to deliver product on time,   after fighting, pleading and begging to have materials sent to me on time I have finally had to cut my losses and have gone  else where to find a high quality aaffordable lacquer. 

Ultra is a gift from Heaven, they are local and so know the issues the Californian finisher faces ,Unlike some of the other national brand manufactures that have no clue what or how their 275 Lacquer preforms.  having toured there facility I found that they are very attentive to quality control.

The next thing about Ultra is that they are Local so if I run out of stock I can go down and pick it up. If they don’t have a batch made I know who to talk to. 

The next thing, Pricing the pricing we have from them is fantastic;

Water white 275  $98 for a 5 gallon pail

Water white 275 sealer $96 for a 5 gallon pail

White undercoat $96  for a 5 gallon pail

White Top coat $104 for a 5 gallon pail

These are phenomenal prices and for a good product.

Call me if you  are in the area and would like me to come by and spray out a sample for you. Try it you’ll like it.

We also have a 550 that is legal to use providing you only consume no more than a gallon a day that is only $88.90 a five.
