Hello. I'm Steve Smith. I'm a Scientist. I formulate the products that my company, Smith & Co. manufactures.

You can order Smith's Damp Concrete Primer from the factory store. Do you want your local paint store to stock it? Email us and we will send you literature to take to them.

Now, I'd like to tell you about Smith's Damp Concrete Primer:

What it does: It chemically bonds to any topcoat we know of, creating a strong water-resistant chemical bond. They stick and stay stuck. Smith's Damp Concrete Primer forms chemical bonds with properly prepared concrete, as well as with freshly applied isocyanate-cured polyurethane paints or polyurethane elastomeric coatings or amine-cured epoxy paints or epoxy coatings.

Why it is valuable:

Smith's Damp Concrete Primer contains no solvents, thus legal to apply anywhere on any structure.

Smith's Damp Concrete Primer (DCP™) self-emulsifies by mixing with water. This makes it more economical than two-component epoxy primers for applying any maintenance or protective coating to concrete.

Being a concentrate, your shipping costs are less.

You save money as well as gaining better coating reliability. As a contractor when your work sticks and lasts and the customer sees your work stays stuck year after year, you get more word-of-mouth referral business.

Old, dirty or oil-contaminated concrete should be treated first with Smith's Permanent Concrete Sealer.

Here's how to do it:

In order to use Smith's Damp Concrete Primer, add two parts by volume tap water to one part by volume of DCP. Mix well, and observe that the mixture becomes an opaque tan liquid. The mixture may be applied by the same kind of rollers or brushes as are used for latex paints.

The adhesion-promoting film is effective in a thickness of only a few thousandths of an inch (a hundred microns or less). This film is distributed over a surface by brush, spray or roller application of the emulsion onto the cement surface. Natural evaporation of the water will leave a thin film of the DCP resin itself directly wetting the cement surface. One quart of concentrate is adequate for 400 square feet of average concrete. On more porous concrete, more may soak in and the coverage may be less.

A quart of DCP mixed with two quarts of water is to be applied over four hundred square feet or less as above. Use what you mix within an hour. Once applied to a concrete surface, allow to dry until the appearance changes from a tan liquid to a clear, dark amber oily film. Further drying until the film is slightly sticky is ideal. This typically takes one to three hours. Then apply any topcoat according to the manufacturer's instructions. If you see Smith's Damp Concrete Primer turning yellow as it dries, this indicates there was excessive water in that area of the concrete. If the concrete is really wet, instead of merely damp, this may happen. Immediately apply more DCP to disperse the yellow granular material. A normal apearance of properly primed concrete will be a transparent amber film.

Smith's Damp Concrete Primer was introduced in 1992 as a component of a kit for the repair of leaking bathroom floor drains in Sweden. This technology has since been certified by the Swedish agency that regulates such installations, and to date in excess of six thousand floor drains in Sweden have been repaired by our licensees, with no failures.

Smith's Damp Concrete Primer was introduced to the U. S. market in 1999, and we have had no failures in any application.
