PC-Rot Terminator ® Epoxy Wood Hardener is a two part epoxy liquid for structural repairs to wood that has damage caused by insects or rot. Cures slowly to allow maximum penetration. Provides a waterproof seal when cured. PC-Rot Terminator® is 100% active ingredients and contains zero solvents – does not shrink. The mixture of resin and hardener produces a low viscosity liquid that penetrates the distressed wood and cures hard.
