Gap Filling with Resin for Wood Floors in Kent

Gaps between floorboards are one of the most common issues with wooden floors. They cause draughts, trap dirt, and spoil the appearance of your floor. Natural Finishers provides expert resin gap filling services in Maidstone, Kent, and across the South East, creating a smooth, seamless finish that looks fantastic and improves your floor’s performance.

Resin gap filling is the most popular and effective method for filling gaps in wooden floors. It uses a mixture of fine sanding dust from your own floor combined with a specialist resin binder, creating a flexible filler that matches your floor’s exact colour and moves naturally with the timber as it expands and contracts through the seasons.

How Resin Gap Filling Works

  1. Initial sanding – The floor is sanded to produce fine dust that matches your timber
  2. Mixing – The sanding dust is blended with a clear resin binder to create a custom filler
  3. Application – The resin mixture is worked into every gap across the floor
  4. Drying – The filler is left to cure and harden
  5. Final sanding – The floor is sanded smooth to a perfectly level finish
  6. Finishing – Your chosen oil, lacquer, or wax is applied over the entire floor
