Buyer’s Guide for Wood Fillers Used on Floors
Filler Type
Several types of wood fillers can be used on floors, including the following:
- Latex wood filler: This type is water-based and easy to clean up. It is also flexible, so it can move with the wood as it expands and contracts.
- Epoxy wood filler: This filler is more durable and resistant to water and heat than latex fillers. However, it can be more difficult to work with and typically requires longer curing.
- Oil-based wood filler: This is a traditional option made with mineral spirits or turpentine. It is typically more difficult to clean up and has a strong smell, but good for filling large cracks or gaps.
- Polyurethane wood filler: This type is durable and can be used for indoor and outdoor applications. It also can be sanded and painted after drying.
Note: these fillers may vary in working conditions depending on the surface and the crack size you want to fill.
Drying Time
The drying time of wood fillers can vary depending on several factors, including the type of filler and the humidity and temperature of the area where it is being used.
Prioritizing drying time based on project requirements and balancing it with the desired quality of the repair is crucial to achieve optimal results with wood fillers used on floors.
- Latex wood filler: It can dry within a few hours and be ready to sand in 24 hours.
- Epoxy wood filler: It can take several hours to set and dry for sanding in 12-24 hours.
- Oil-based wood filler: Drying time for these fillers can range from several hours to overnight, depending on the humidity and temperature.
- Polyurethane wood filler: It can dry in 24-48 hours but can also be affected by temperature and humidity.
Durability and Strength
Here’s a brief overview of some common types of wood fillers:
- Latex wood filler: This type of filler is relatively durable but not as strong as some other options. It can fill small cracks and gaps but may not be suitable for larger repairs or heavy traffic areas.
- Epoxy wood filler: This type is the most durable and strong. It is resistant to water and heat and can be used for large repairs or heavy traffic areas.
- Oil-based wood filler: It is durable but may not be as flexible as other options and may crack over time in an area where the wood expands and contracts. It's good for filling large cracks or gaps.
- Polyurethane wood filler: This type is durable and can be used for indoor and outdoor applications. It is waterproof and can expand and contract with wood.
It’s important to note that overall durability and strength also depend on the preparation and application of the filler. Proper surface preparation and correct application technique are crucial to achieving optimal results and repair longevity.
Wood Filler or Putty?
Wood filler and wood putty fill gaps, cracks, and holes in wood surfaces, but they have some key differences.
Wood filler fills small to medium-sized gaps and cracks in wood surfaces. It is made from a combination of wood particles and a binder and is typically sandable and stainable once dry. It can come in oil- or water-based options or even a two-part epoxy option.

Wood putty, on the other hand, is a substance used to fill small holes and defects in wood surfaces. It is typically made from a mixture of sawdust or wood flour and a binder, such as linseed oil [1].
Wood putty is usually not sandable or stainable and is not as strong and durable as a wood filler.

According to our woodworking experts, it’s important to note that selecting one will depend on the specific project you have in mind and the surface condition you want to repair.
While wood filler is better for larger cracks or gaps, wood putty is the better choice for small defects and surface imperfections. A professional can also help you decide which is better for your project’s specific needs.
