What Fillers can I use for wooden floors?

There are many reasons and advantages to using fillers on wooden floors, other than the visual effect from the client’s perspective that can make a great difference. Its primary use is to stop products that are being applied to the floor from getting in between boards to reduce losing product and avoid future issues like side bonding. 

In the case of Pallmann Magic oil and Magic Oil Ergo, side bonding will not occur but the product only cures when it is thin and in contact with air, so if the filler is not used, it remains liquid which can cause other issues. Here is a breakdown of what ultimate floor care can offer when it comes to filling gaps in your wooden floor. 

Spray Cork. Used mostly to fill expansion gaps around the edges of wooden flooring to allow for expansion and contraction during changes in the temperature and humidity levels. It is most popular to repair or replace the cork strips used on parquet or wood block floors. Spray cork is a very flexible liquid cork that is applied with a standard sausage-type gun to Inject into the gap where it is required. Remove any excess that has been raised and allow it to expand and dry in the gap, then sand off the excess. This allows the flexibility for the wood to naturally move without being under stress. 

Resin Wood Filler. This filler is available in the industry as a great option to fill large holes or gaps in the wooden flooring. One of the advantages of this product is it comes in a variety of different colours depending on the type of wood you are filling. It’s a 2-component filler to be mixed with a hardener. It is a very fast drying product so must be applied as soon as it has been mixed. The idea is to apply it, sand any excess off the top to the same level of the flooring and depending on the colour you choose once the floor is finished it looks like a grain or knot in the floor. If filling a hole left by a knot, black is the best colour to use. 

Joint Filler. An acrylate adhesive filler that is used to close up expansion joints and gaps in flooring. The benefit of using this for gaps in joints is it is an adhesive as well as a sealer giving it the hold it will need to connect flooring boards together. Or other materials such as thresholds, masonry, or other types of hard flooring that the wooden flooring is connecting to. These filler tubes come in a range of colours to work well with hardwoods, softwoods, and tropical woods. Applied with a suitable sealant cartridge gun, when it’s applied any excess will need to be removed straight away with water. This product can be coated over the top after 24 hours of being applied. 

Pallmann Pall-X Kit. A water-based resin wooden flooring filler that works by being mixed with sanding dust that you have taken off the floor. The benefit of using this product is it keeps the same colour and is easy to apply into the gaps. This product has to be mixed with the fine sanding dust of 100 grit until you get a consistency of between single and double whipped cream. This can then be applied to the floor with a Pallmann applicator trowel into the gaps over the floor. Once the product is dried then you can sand off any excess you have on the floor or above the gaps. This product can only fill gaps up to 2mm. 

Pallmann Pall-X Filler . Similar to the pall-X kit this filler is the next in the evolution chain for fillers in the Pall-X range. It has been made to fill gaps up to around 3mm and because of its fibre-reinforced attributes, it is longer lasting in flooring that needs that flexibility to expand and contract in different climates and is more suitable for suspended floors which suffer from greater vertical movement.
