Method 1: Filling With Resin
The most common technique for filling gaps is to mix wood dust from the sanded floor with resin to form a paste that is pressed into the gaps and then sanded when dry.
Gap filling using resin mixed with pine dust is only recommended for gaps up to 3mm wide, loss of the resin gap fill may occur through the natural movement of the floorboards. GJP Flooring cannot be held responsible if this occurs. Never wet mop you floors, always use the correct cleaning products to clean your floors. This is the least expensive method of filling gaps, but we believe it is also one of the least effective.
