Damp Concrete Primer™

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. Since it contains no solvents it is legal to applly anywhere on any structure. 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 sticks and stays stuck year after year, you get more word of mouth referral business.

Two parts by volume tap water to one part by volume of DCP 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. This film is distrubuted over a surface by brush, spray or roller application of the emulsion onto the cement surface. Natural evaporation of the water will leave a 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 will be less.

Use what you mix within an hour. Once applied to a concrete surface allow to dry unti 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 manufacturers instructions. If you see the Damp Concrete Primer turning yellow as it dries, this indicates there was exessive 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 graular material. A normal appearance of properly primed concrete will be a transparent amber film.

Besides forming chemical bonds with properly prepared concrete, the Damp Concrete Primer will form chemical bonds with freshly applied isocyanate-cured polyurethane paints or polyurethane elastomeric coatings or amein-cured epoxy paint or epoxy coatings. Then they stick and stay stuck. It chemically bonds to any topcoat we know of, creating the stongest, most water-resistant chemical bond possible.

Damp concrete Primer was introduced in 1992 as a component or 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 licenses, with no failures.

Damp concrete Primer was inroduced to the US market in 1999, and we have had no failures in any application.
