ROTFIX
PENETRATING EPOXY WOOD SEALER
RotFix is an ultra-low viscosity penetrating epoxy wood consolidant engineered to soak deeply into soft, punky, and deteriorated wood fibers. Unlike many so-called “penetrating” epoxies, RotFix contains no solvents, allowing for maximum epoxy solids penetration and superior structural reinforcement.
Designed to harden and stabilize weakened wood, RotFix restores strength by saturating compromised fibers and curing into a durable, solid base. It also functions as a chemical bonding primer for use with SculpWood Putty and SculpWood Paste, creating a permanent, non-shrinking repair system that resists cracking over time. Together, these products form a long-lasting epoxy wood repair solution ideal for windows, doors, trim, columns, siding, and other exterior or interior wood components.
RotFix can also be used as a stand-alone wood hardener to consolidate soft wood prior to priming and painting. By stabilizing the substrate, it helps improve primer adhesion and extend the lifespan of your paint system.
Important: RotFix does not kill active rot fungus or prevent future fungal growth. For long-term protection against wood decay, treat the affected area first with a borate wood preservative before applying RotFix.
