Epoxy filler
Epoxy filler
Epoxy filler can be used to repair broken and dented corners, rotting window sills, door jambs and exterior molding that are difficult to remove and expensive to replace. Epoxy is easy to mix and to mold. When it hardens, is easy to carve and sand. It sticks very well and is formulated to flex and move with the wood, without cracking and falling out like some other wood fillers.

Long lifespan Very high performance, weather and water resistant glue. Sticks to almost any material. Non toxic When cured, epoxy is rather safe for the user, it doesn't emit toxic fumes. It may leaches small quantities of toxic compounds (like Bisphenol A) through hydrolysis (exposition to water), photolysis (exposition to direct sun light, UV rays), scratching etc. If the epoxy filler is applied on a large surface, risk of leaching is higher (1) |
