Simtec Water borne clear is a Super Clear High Gloss Polyester Topcoat. It is buffable and buffs to a high gloss. It is also very scratch resistant.

This product can be applied over our clear sanding sealers (28x50TS, 20x50TS 0r 28x6). It can also be applied over a color coat such as House of Kolor or a polyester color (any thing else should be tested by the user). 1900 series will deepen and enhance the look of the wood or color it is sprayed over.

Prepare the surface to be coated by sanding with 320 or 400 grit sandpapers non-sterated. Then wipe the surface with a slow evaporating lacquer thinner or IPA (Isopropyl Alcohol). After wiping the surface with the solvent do not touch with hands, you may leave oils from your hands on the surface causing fisheyes. Give special attention to surface preparation to ensure a good quality finished product.

Now prepare the polyester topcoat by adding the correct amount of catalyst, 2 % or .5 oz per quart. Be sure to mix the catalyst in thoroughly. 1900 series requires no thinning and your pot life is 20 minutes at 77 degrees F.

Simtec’s 1900 series can be applied with an Hvlp or Lacquer type gun, which ever is acceptable in your area. Use 25-45 lbs. Air pressure with the Lacquer type gun, holding the spray gun 12-18 inches from the surface being coated.

You can apply 3-4 coats in 20 minutes you need to wait at least 5 minutes between coats to allow the 1900 series to flow out. Do not recoat after 1.5 hours. You must let it cure then sand and start over again.

Let the product cure for a day (You can put in a curing room at temperatures from 85 degrees F to 100 degrees F) then you can fine sand and buff the product out to a beautiful high gloss finish.
