Bona Gap Master 310ml

Bona Gap Master is a flexible, acrylic based mastic designed for filling gaps and cracks in parquet, solid wood and engineered wood flooring. It is ideal for sealing joints around skirting boards, thresholds and floor edges, helping create a neat, professional finish.

This silicone free, solvent free and odourless filler remains permanently elastic, allowing for 7–15% movement to accommodate natural wood expansion and prevent cracking. It can also be used to repair small gaps or minor damage in wooden floors.

Once dry, Bona Gap Master can be sanded and finished with Bona water based lacquers for a seamless result. It is available in a range of colours to match many popular wood floor tones.
