How to prepare a surface for bonding with PC-Masonry™

Old concrete must be clean and profiled or textured. Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove contaminants such as dust, dirt, oil and grime with a solvents such as denatured alcohol (ethanol), acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner. Mild detergent solution in water is also good removing contaminants. Use a clean paper towel or rag for wiping. Do not use mineral spirits or paint thinner for removing contaminants. New concrete should be a minimum of 21 days old. Prepare the surface by rough-grinding, scarifying or by using other equipment that will give a roughened profile. A roughened surface is imperative for good adhesion. Always be sure the bonding surfaces are prepared in advance before mixing product. Mix only enough PC-Masonry that can be used within 20 minutes at 75 °F (24 °C). Remove rust and loose paint with sandpaper or wire brush. Epoxy typically sticks to most paints. If there is a concern of the paint’s adhesion then remove it with sandpaper or wire brush. Smooth, glossy and shiny surfaces should be roughened using sandpaper to increase adhesion.

How to clean-up after PC-Masonry™ application

Clean up mixed epoxy before it cures with paper towels and solvent. Denatured alcohol (ethanol), acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner are suitable solvents for removing uncured epoxy. Cured epoxy can be removed with paint stripper or remover.
