Timbabuild® FINISH by Chemfix is a high-performance, two-part wood filler designed to create a perfectly smooth final surface over Timbabuild repairs. Supplied in a patented silicone cartridge, it ensures effortless and accurate mixing of resin and hardener using a standard silicone gun—no manual blending required.

This durable finishing compound is ideal as a ‘top coat’ after sanding any Timbabuild repair, helping to eliminate imperfections, pinholes, and uneven textures. It cures rapidly, ready to sand in just 30 minutes at 20ºC, and can then be primed or painted with ease.

In addition to its use alongside the Timbabuild system, FINISH can also be used as a standalone wood filler for small, non-structural repairs—without the need for a primer. Its styrene-free formulation makes it safe for indoor use, producing no harmful odours and earning a VOC rating of A+ for indoor air quality.

The cured filler offers a high-strength, durable surface that can be easily stained, varnished, or overpainted to match surrounding timber. The re-sealable cartridge is also designed for easy storage and reuse, reducing waste and increasing convenience.
