Gap Filling Restoration
Gap filling restoration is the process of using resin or solid strips to fill small gaps that have developed in between wood floorboards. Over time, poorly acclimatised planks and/or moisture and temperature fluctuations will result in expansion and contraction of wood flooring, causing gaps to arise. Generally, gap filling is an optional process. The key advantages to implementing this procedure include draught eliminating, prevention of dirt build-up and to tighten the existing flooring.
As part of the installation and restoration process, Floor Sanding can provide expert, professional gap filling services to give your floors a seamless finish. Below we have created a short guide to explain the key elements of the process.
1. Resin Filling
Resin filling is ideal for filling wooden floorboards that have been installed with a glue adhesive and have gaps no wider than 5mm. This process involves combining a clear resin filler with sawdust gathered from the floor sanding procedure. Ideally, the sawdust will be a close or exact colour match to the floorboards and the paste should have an easily trowelled consistency. To apply the resin, a spatula is recommended.
2. Solid Wood Strip
For those who really want the best result possible, filling the gaps with wood slivers is the best method. This process involves using high-strength wood adhesive glue to fix the solid wood strips in the gaps. Notably, it is important to ensure the wood strips match the colour of the floorboards and that they are placed over a plywood sub-floor or directly on a joist.
3. Rubber Strip
Rubber strips such as black expanding neoprene strips are great for their flexibility and moisture wicking properties. Depending on the type of rubber strips used, some are self-adhesive, while other will require glue to secure them in place. Although rubber is 100% waterproof and extremely long-wearing, is it not aesthetically pleasing and is this the least commonly used method of gap filling.
