PC-Petrifier wood hardener ® is a single component adhesive, formulated to fully penetrate and revitalize rotted wood. Modern technology has allowed us to develop a water base consolidant that is environmentally friendly. PC-Petrifiers'® low viscosity allows deep penetration into soft rotted wood fiber, restoring old wood to near structural integrity. PC-Petrifier wood hardner ® should be considered a non-structural wood hardener.
