Using resin to fill gaps in flooring can be very good for floorboards, parquet flooring and some types of engineered wood flooring.. You need to know that it is not the best way to fix every type of flooring. The resin filling for gaps in flooring works when the gaps are not too big, the flooring is in good condition, and the floor does not move too much. Resin filling for gaps is a solution when you have old floorboards or parquet flooring with small gaps. You have to think about the size of the gaps in your flooring and the condition of your flooring to decide if resin filling for gaps is the method for your flooring.
What Is Wood Floor Gap Filling With Sawdust & Clear Resin?
Gap filling using sawdust and clear resin is a restoration technique employed in floor sanding. It involves mixing wood dust obtained from sanding your own floor with a clear resin. The mixture is then used to fill small and medium-sized gaps, imperfections on the floor, and small openings between wood blocks or planks. The technique is advantageous since the filler will blend more naturally with your wood floor than other conventional fillers.
The wood dust is really useful for filling gaps because it comes from your floor. This means you can make the filler yourself. After you put the filler on the floor you need to sand it. This is so you get a finish. The wood dust is especially good, for people who own homes and want their wood floors to look better. They do not have to replace pieces of wood on their floors.
When Resin Gap Filling Works Best
Sawdust and clear resin gap filling is usually most effective when the floor is stable and the gaps are mainly cosmetic rather than structural.
It is often a good option for:
- small to medium gaps between timber boards
- stable parquet floors with fine openings
- original floorboards that are sound and well secured
- floors that are already being sanded and refinished
- reducing visible lines, minor draughts, and dirt traps between boards
In the right conditions, resin gap filling can significantly improve the overall look of a timber floor and help create a cleaner, more finished appearance.
When Resin Gap Filling Is Not the Right Solution
Not every floor should be filled with resin. In some cases, the filler may crack, loosen, or fail if the floor continues to move.
Resin filling may not be the best option for:
- very wide gaps between floorboards
- loose or uneven boards
- floors with significant seasonal movement
- damaged, split, or rotten timber
- subfloor issues causing instability
- gaps that require a more substantial repair
Where movement is ongoing, a more durable repair method, such as wood slivers, securing loose boards, or replacing damaged boards, may be more appropriate. A proper inspection is the best way to determine which solution is likely to last.

- Helps keep the air out: a lot of old wooden floors let cold air come up through the gaps, and using resin to fill the gaps can help stop this.

Types of Gaps in Wood Floors
Not all gaps in floors are the same so they can't all be fixed in the same way. Some gaps happen because of changes in seasons while others are because of age wear or problems with the floor's structure. Figuring out what causes the gap helps decide if filling it with sawdust and clear resin will. If a different fix is needed.
Seasonal Gaps
These gaps show up as wood gets bigger and smaller with temperature and humidity changes. Small seasonal gaps are common in homes and might still be okay to fill with resin if the floor is stable.
Structural Gaps
These gaps happen because of movement, in the floor boards, uneven base floors or weak attachments. In these cases the floor might need repairs to make it stable before any filler is used.
Age-Related Gaps
Old floorboards and parquet floors often get gaps because of natural shrinkage and long-term wear. If the wood is still good filling can make the floor look much better. Badly worn boards might need a more extensive fix.
Gap Filling for Different Floor Types
Original Pine Floorboards
Original pine floorboards are really common in homes in London. If the boards are stable and the gaps are not too big you can improve them with resin gap filling. In homes some floors might need a mix of repairs especially where boards have come loose over time.
Oak Floorboards
Oak floors usually work well with sawdust and resin filling. This is because the filler can match the timber dust made during sanding.. The most important thing is that the floor is stable not just the type of wood.
Parquet Floors
Parquet floors often look better after resin filling especially where there are gaps between stable blocks. This can make the floor look great before finishing. If the parquet blocks are loose you should fix them first before filling.
Engineered Wood Floors
Some engineered wood floors might be okay for filling. It depends on how the floor is made, the wear layer and how it was installed. Floors that move a lot or are not fixed in place might not be good, for resin filling.
Resin Gap Filling vs Wood Slivers vs Board Replacement
Different floors need ways to fix them. The best way to fix a floor depends on how big the gapsre how much the floor moves and what kind of shape the wood is in.
Sawdust & Clear Resin
Best for small to medium gaps in stable floors where the goal is to improve appearance and create a more seamless finish.
Wood Slivers
Often better for wider and more consistent gaps where a more solid timber repair is needed.
Board Repair or Replacement
Usually the right choice where boards are badly worn, split, loose, or structurally damaged.
If a floor has more than one issue, the most effective result may come from combining different repair methods as part of the same restoration project.

How We Carry Out Wood Floor Gap Filling With Resin
Our gap filling service is usually completed as part of a professional floor sanding and restoration process.
1. Floor Inspection
We start by looking at the floor to see what kind of timber it is, how wide the gaps are and if the floor boards or parquet blocks are steady enough to fill with resin.
2. Preparation and Repairs
Any loose elements, damaged areas, or obvious defects that need attention are identified before filling begins.
3. Sanding and Dust Collection
The floor gets sanded to get rid of finishes and to make the surface ready. We collect dust from your floor for use in the resin mix. The dust, from your floor is actually used to make the resin mix.
4. Filling the Gaps
The sawdust and clear resin mixture is applied into suitable gaps and surface openings to improve uniformity across the floor.
5. Final Sanding
The filler needs to dry. Then the floor is sanded again. This is done to make the floor really smooth. It also helps to get rid of any material that is not needed. The floor needs to be smooth and even. So the floor is sanded again after the filler has dried.
6. Finishing
The floor that has been fixed is then closed with the finish you want like lacquer or oil to keep the wood safe and make it look really good.
