Professional wood fillers for filling gaps, cracks, nail holes, and board joints during timber floor sanding. A proper fill before sealing and coating ensures a smooth, consistent surface and prevents dirt and moisture from collecting in open joints.

How Timber Floor Fillers Work

Most professional fillers are mixed with fine sanding dust from the floor itself, creating a colour-matched paste that blends with the surrounding timber. Water-based formulas dry quickly, sand easily, and do not react with water-based sealers or lacquers — making them ideal for modern finish systems.

Browse our filler range from Berger-Seidle below. For best results, apply filler after the initial coarse sand and before the fine sanding pass.

Why Use a Timber Wood Filler?

Why Use a Timber Wood Filler?

Wood filler plays a critical role in achieving a flawless timber finish. It fills imperfections that would otherwise remain visible after sanding and coating. Using a high quality filler ensures the final surface looks uniform and structurally sound.

EcoGrit wood fillers are formulated to bond strongly with timber and move naturally with the wood. This reduces the risk of cracking or shrinking over time. They are suitable for residential and commercial projects where appearance and durability matter.

Questions about our Wood filler solution?

Can wood filler be used on timber floors?

Yes, wood filler is commonly used on timber floors to fill gaps, cracks, and nail holes. It creates a smooth surface that improves the appearance of the finished floor. Using the right filler helps achieve a more uniform and professional result.

Does wood filler accept stain or oil?

Most quality fillers are designed to accept stain or oil once fully cured. The final colour may vary slightly depending on timber type and finish. Testing on a small area is recommended for best colour matching.

When should wood filler be applied during floor preparation?

Filler should be applied after initial sanding but before final sanding. This allows imperfections to be fully exposed and filled properly. Final sanding ensures the filled areas blend smoothly with the surrounding timber.

Will wood filler crack over time?

High quality fillers are designed to move with the timber and resist cracking. Proper application and correct layer thickness also reduce the risk of future cracks. Choosing the right filler for your project is essential for long term performance.

Can wood filler be sanded easily?

Yes, once dry, wood filler sands smoothly and blends into the timber surface. It should feel flush with the surrounding wood before applying any finish. Easy sanding helps achieve a clean and even result.
