A little lesson (again) on sealer discoloration. Forget this if it is asphalt emulsion or Gilsonite type sealer. Coal tar type products repel solvents. If you look really close what you are seeing as discoloration is really millions of tiny specks of "oil" or whatever the solvent that has been "repelled" up through the paint to the surface and it's brown due to the reaction with the coal tar. This is not nearly as noticeable on some colors as it is on while since white shows even slight discoloration more. Now before we start arguing remember the differences in solvents. Acetone would tend to do this less since it's a "hot" solvent and evaporates quickly from the paint, less solvent = less reaction, conventional alkyds with naphtha (a very "oily" and slow drying solvent) sits on the sealer far longer causing more of this effect. The same is why different people here report different experiences when painting on sealer. Different brands of paint contain different solvents or blends of solvents and different brands of sealer contain different percentages of coal tar, different sealcoaters use different additives etc. So there is no "hard & fast" rule except to be sure you are safe, use latex on sealer. (After all; I've seen "sealcoaters" who aren't real sure what they are putting down so you can't be sure what you are painting over unless you have repeat experience with the same people who always use the same thing). The reason it doesn't apply to the first 2 types is because asphalt sealers will absorb the solvent to a degree as will Gilsonite. As far as the other post about acrylic & acetone look up the definition of acrylic. It has nothing to do with requiring water although a lot of people use it that way. (To many people contains water = acrylic which is not necessarily all their fault. The way some manufacturers describe a variety of products , not just pavement stuff, you can easily get that impression) The actual definition of "acrylic" is so broad it can be almost anything.

Dan , If I'm not mistaken, SW Acetone is there answer to the new VOC regulations in the N.E. DC metro just became part of the new regulations this year, and this is the only other paint I know of besides Latex that meets the new VOC laws, and its the only non-latex traffic paint SW sells. New Jersey might have there own regulations but if they are part of the OTC regulations, you should be able to use Acetone.

Jim, do you buy your blue already mixed? my blue turned green also. But if you mix blue dye with white paint it stays blue. Don't ask me why. Are you going to the show? Give me a call.

Can anyone give me the product number for SW Acetone? Thanks

There are two different LOW VOC paint by SW, One is TM5713 yellow and TM5712 white, the better of the two is TM5626 for white and TM5636 for yellow. I feel the 26 and 36 covers a lot better the the 12 and 13. We used 2000 gallons of the 5626 and 5636, then to save a buck a gallon we tryed the 5612 and 13. WHAT a difference, the dollar I saved cost me more in the long run, doesn't cover nearly as well and seams to be a little thinner. The we went back to the 26 and 36 again and will stay with it again this upcoming year. Jim

Jim (and others) .... I'm interested in paint prices everyone else is paying for acetone and alkyds. I can't find any paint that is worth what I'm having to pay. Makes no difference who manufactures the paint. It used to be I could find a decent yellow and white paint for $8 per gal. Now its over ten regardless of the manufacturer. All of it is less than adequate. I can understand an increase in price but not when the quality has gone down. Still haven't ordered from Technical Coatings. Just got their price list but shipping is going to make it a little pricey.

My SW numbers are TM5626 White, and 5627 Lead Free Yellow. I don't know if it makes a difference but we also use JCL air line painters. Maybe the airless is different.

Before the end of the year, my price was around 10.25 a gallon for 2000 gallons at a time. Just for peoples info, Martin Semoer (?) Paint is made by SW. You maybe could get a better price but mine was the same. Jim

Not sure of the TM number (guess I should be) but its SW Setfast Acetone. Paying $11.68/gal picking it up at the stores as we need it. I'm going to have to start buying in bulk next year especially with additional increases. That will at least partially pay for a small shop/yard that we will need because this is the year I grow the company. (that's a nervous face in case you couldn't tell) Any good tips on buying a shaker? Dave

Ask your SW store the next time they are getting new shakers. I got mine for 100.00 and still working after 4 years. Jim
