Reviews of the Top Wood Fillers to Use on Floors

1. Timbermate Wood Filler, Water Based, 8oz, Natural

Timbermate Wood Filler is a type of water-based wood filler designed to fill cracks and gaps in wood surfaces. It is made from wood fibers, pigments, and a binder. It is also eco-friendly as it is non-toxic, non-flammable, and has low VOC.

I appreciate its smooth consistency, which makes application with a putty knife a breeze. Once it dries, it seamlessly integrates with the surface, allowing for sanding, staining, and painting.

Over time, it proved to be durable and flexible, as it expands contracts with the wood, which can help prevent further cracking.

Buyer’s Guide for Wood Fillers Used on Floors

Filler Type

Several types of wood fillers can be used on floors, including the following:

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.

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.

Between these two options, it’s important you select a product depending 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. If you’re unsure, don’t hesitate consulting with a professional can also help you decide which is better for your project’s specific needs.
