The Everbuild Wood Filler Hardener / Catalyst Tube is a specialized, professional-grade chemical activator engineered to accelerate the curing process of two-part polyester wood fillers. Designed for both interior and exterior joinery and carpentry projects, it provides contractors and woodworkers with a reliable component to achieve fast, rock-solid repairs on damaged timber, door frames, and window sills.
 
Formulated with precision-blended peroxide paste, this catalyst initiates a rapid chemical cross-linking reaction when mixed thoroughly with neutral base fillers. It triggers a uniform set even in cooler ambient temperatures, transforming soft filler compounds into a durable, dense material that can be successfully sanded, planed, drilled, and painted over within minutes of application.
 
Supplied in a convenient squeeze tube for exact, controlled dosing, the paste allows tradespeople to mix only the precise amount of hardener required for the task, minimizing product waste. It serves as an essential trade consumable for ensuring that structural and cosmetic wood repairs achieve full strength and long-lasting performance on busy work sites.

Works with most common 2 part wood filler systems.
Available as loose tubes.
