Buying Guide

Match material to the repair type

Use two-part epoxies or petrifiers for structural rot and deep voids; use premixed fillers for surface repairs and small gouges

Consider sandability and finishing

Choose a filler that sands smooth and accepts stain or paint if you plan to refinish visible surfaces

Check water and weather resistance

For outdoor or moisture-prone projects, prefer formulations noted for water resistance or epoxy-based durability

Look at kit components and convenience

Kits that include filler, hardener, and applicators simplify multi-step repairs and reduce the need to source extras

Balance cost with coverage and size

Larger containers reduce per-use cost for big jobs, while smaller tubes are better for spot repairs and trim work
