Gap Filling

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.

Method 2: Solid Pine Strips/Wood Slivers

Using specially manufactured strips of reclaimed pine, the strips are glued with a D3 PVA glue and hammered into the gaps before being chiselled off and polished back.

This has the advantage of being less prone to cracking out and the disadvantage of being more expensive. Again this procedure is completed after the 80grit sanding. The results are spectacular – a solid pine floor without relaying!

Disclaimer: wood slivers / strips are the most reliable method of filling gaps. Please note, wooden floor boards will expand & shrink through the changing seasons due to temperature and moisture variation. With some floors this can result in gaps forming between boards that have been filled with either technique.

Gap Filling Disclaimer

Please note, wooden floor boards will expand & shrink through the changing seasons due to temperature and moisture variation. With some floors this can result in gaps forming between boards that have been filled with resin or PVA. Due to the natural movement in your floors, the PVA / resin paste method can be unreliable and drop through or get vacuumed up with gaps over 3mm wide. This can also result in some loss of the gap filler between your floor boards over time. GJP Floor Sanding Brighton is therefore unable to guarantee resin / PVA gap filler solutions

Important notes on resin gap filling. The method most widely in use is a resin filler mixed with wood dust creating a thick paste that is applied with a flat edge filling tool. This method only used if clients aren’t too worried about how long they want this filler to last. All resin eventually shrinks and with boards, your filler either ends up in the vacuum cleaner dust bag or falls through into the space below the boards, leaving you once again with unsightly black gaps and a lot of draught
