Gap Filling

Wooden flooring is a natural product and as such, it may contract to certain extent depending on the installation method, timber species or environment. Because of this contraction gaps may open between planks in time and to improve this (when required), we offer a gap-filling service.

There are several methods for filling gaps on wooden floors used by flooring companies.

Gap filling with resin & saw dust

The most common method used is mixing clear resin filler with sawdust. The dust is collected during the sanding process from medium to the fine grit of sanding. The method is very popular for gaps of up to 5-6 mm and largely used on parquet flooring and floorboards.

The main advantage of this method is that the filler has the same colour as the floor because of the sawdust was collected during sanding from the same source. Another positive feature is that it dries relatively quickly and provides a good basis for a smooth finish. This method is more efficient when it is applied to parquet flooring or tongue-and-groove planks. That is because the gap filler won't fall through and to reduce the possibility of that happening, we select products of a high quality.

Our gap filling service always comes with careful inspection and wood floor repairs - refitting of the floor if that is necessary to improve the stability of the floorboards or parquet blocks.

Gap filling with wood slivers

Slivers are strips of pine wood fitted and glued down into the gaps - another process applicable mainly for wider gaps and often recommend for pine floorboards. It has a natural effect, but if used on a large-scale may not be very presentable and for the eyes. However, wood slivers can improve the solidness of the boards and improve floor insulation, reduce draft from the voids below the floorboards.

Both methods above are applied before the floor sanding process is complete as the last sanding will smoothen the surface and prepare it for the oiling or varnishing.

Cosmetic gap filling with colour mastic

Gap filling with mastic such as the Bona Gap Master filler can be used for tiny gaps between the planks, minor repairs, cracks and filling around beadings and skirting boards. You can find this filler in various colours and it is the ideal application on already finished floors.

Why is gap filling important part of the floor restoration works

Gap filling is a crucial step during floor restoration for several reasons:

• Gaps between floorboards can weaken the overall structure of the floor. Filling these gaps helps to maintain the strength and stability of the floor, preventing boards from shifting or becoming loose.

• Gap filling can stop moisture, dirt, and debris to accumulate, which can lead to damage over time. Moisture can cause wood to warp, swell, or rot, while dirt and debris can create friction that wears down the wood.

• Improve energy efficiency - gaps in the floor can lead to drafts and loss of heat, making it harder to maintain a consistent temperature within a room. Filling these gaps can improve the insulation of a space, reducing energy costs for heating and cooling.

• Gaps in the floor can detract from the appearance of a room, making it look unfinished or poorly maintained. Filling the gaps results in a smoother, more uniform surface that enhances the visual appeal of the floor.

• Walking on a floor with gaps can be uncomfortable, as the gaps can cause uneven surfaces. Filled gaps contribute to a smoother walking experience, making the floor more pleasant to walk on.

• Gaps in the floor can provide entry points for pests such as insects or rodents. Filling these gaps helps to seal off potential entryways, contributing to a pest-free environment.

• Gaps can affect the acoustics of a room, causing echoes or making it sound hollow. Filling the gaps can improve sound quality by reducing the transmission of noise through the floor.

Overall, gap filling is a critical step in ensuring the longevity, functionality, and appearance of a restored floor.
