PRESTAIN
CONCRETE COLOR STAIN
Natural lasting color for concrete surfaces
Concrete Color Stain (also known as PreStain) is a water-based, penetrating color system that provides rich, lasting color on exterior, interior and below grade concrete, masonry and X-Bond Microcement surfaces. This environmentally responsible system penetrates into the pores of the cementitous surface, to create a long-lasting and colorful surface, resulting in a translucent color finish which allows the variation and natural movement of the concrete to be visible through the stain.
In addition it solidifies crumbling surfaces. Unlike competitors SEMCO’s PreStain Color is proven to last through all kinds of climates, conditions and traffic.

Rich, lasting color for concrete surfaces
Application Instructions
Airless sprayer
tip size 15, 600 PSI
Pump sprayer
2 coats minimum
Roller
2 coats minimum
Apply at temperatures from 50°F to 90°F
-
HOW : Lightly sand the surface with a 60 grit sanding disk. Clean all debris
PURPOSE : Removes excess texture and ensures chemical bond
-
HOW: Using fine pump sprayer, spray light coat of PreStain Base on to surface and avoid large drops. Work in 2 man teams side by side(1 with Pump Sprayer and 1 with HVLP). For concrete surfaces spray thin coats with HVLP.
PURPOSE : Ensures chemical reaction of Natural Grain effectHOW: While still wet apply PreStain Color (PreStain Base and PreStain Activator combined, always stir the contents, avoid shaking) with an HVLP, airless sprayer with tip size 17, or a sprayer that is capable of atomizing liquids. (DO NOT ALLOW PUDDLING)
PURPOSE: Do not shake to avoid in container reaction. No puddles for even color, must spray with low pressure for a pigment reactionHOW: Move across area from left to right as you work your way down the surface, avoid missing any areas of the surface. Avoid stepping in Natural Stain
PURPOSE : Ensures the finish and color stay consistent.HOW: The PreStain Color will then begin to dissipate and as the product forms to the contours of the X-Bond surface.
PURPOSE: Chemical reaction creates the Natural Grain lookHOW: After drying, check if any area requires touch up. If necessary, lightly fog PreStain Color over areas that require touch up
PURPOSE: Ensures a nice finish
