"Gap filling a floor is an option that many people like since it brings a uniform finish to the floor.  Because of the circulation of cold air brought in through the air bricks; gap filling insulates the your living area  and stops draughts. It also prevents a build up of dirt between floor boards."

1.Resin: fine dust from the floor being sanded is mixed with a resin and applied to gaps with filling knife.

2.Solid Pine Strip: strips of reclaimed pine are glued, forced into the gaps, and chiseled back.
 

Method 1- Filling With Resin

The conventional way of gap filling sanded floor boards is to use a resin mixed with the dust that comes off the floor with the 80 grit or finer sanding. This is the least costly method, but also the least effective since it can easily crack and fall out.

• GJP Flooring will make sure that all boards are firm and secure since any movement may cause the gap filling to crack and fall out.
• GJP Flooring make sure that we fill any gap bigger than 6mm with papier mache, string or strips of wood before we fill over the top with the resin filler.
• This will give the best chance of stopping the filling cracking.

Method 2 - Solid Pine Strips

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!

Note: due to the natural movement of wood, strip filling can still fail. Strips are still the most reliable but what can happen is the appearance of small splits rather than complete failure as with resin.
