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

Remove contaminants such as dust, dirt, oil and grime with a solvents such as denatured alcohol, 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.

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-Lumber™ application

Wear disposable gloves to minimize contact with skin. Use denatured alcohol, acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner to cleanup before PC-Marine cures. Clean hands and skin with soap and water.

Cured epoxy can be removed by applying paint remover or paint stripper to soften the epoxy surface. Scratch off the softened epoxy. Repeat as needed.

The PC-Lumber™ does not resemble the surrounding wood

PC-Lumber™ does not have the same natural colors as real wood. Use paint markers or use other stain colors to disguise the repair. Natural grains in the wood are difficult to match.

Use an opaque type of stain or paint.
