Gap Filling

Solvent-based resins mixed with fine sawdust

Gap filling is a process of mixing solvent or water-based resin with fine sawdust that’s produced during the fine stages of sanding. The received mixture is spread with a spatula over the floor, so all existing gaps can take up the mixture. This process can also be repeated if necessary. After a certain amount of time, when the mixture has dried, the floor sanding operator can complete a medium sanding course to remove any excess mixture. This method works for gaps up to 5 mm in width.

Pine slivers

This method uses reclaimed V-shaped pine slivers that are glued with a special adhesive and hammered between the floorboard gaps. We use this kind of method when we have gaps that are wider than 5 mm – this is relatively common in cases where we need to help restore old Victorian pine floorboards. Once the adhesive settles, we can then sand down the slivers. This method is labour and time-intensive, but it produces much more durable and high-quality results.
