PC-Petrifier is a single component adhesive, formulated to fully penetrate and revitalize rotted wood. PC-Petrifier's low viscosity allows deep penetration into soft rotted wood fiber, restoring old wood to near structural integrity. Seal and restore rotted soft wood fibers in window sills, sashes, frames, trim, decorative beams and columns, etc. PC-Petrifier can also be used to prepare old wood for priming and painting. Apply to exposed wood grain to protect from damage.
