What is the best wood filler for hardwood floors?

When it comes to repairing hardwood floors, using the right wood filler is crucial for achieving an invisible fix that blends in seamlessly with the existing flooring. With many types of wood fillers on the market, choosing the best product for hardwood floor repairs can be confusing. In this comprehensive guide, we will discuss the different factors to consider when selecting a wood filler for hardwood floors, and provide recommendations on the best fillers to repair oak, maple, cherry, walnut and other common hardwood flooring types.

What to Look for in a Wood Filler for Hardwood Floors

Here are the key factors to evaluate when choosing a wood filler product for hardwood floor repairs:

Color match – The filler should be available in colors that closely match your floor’s stain or natural wood tone. An exact color match helps the repair blend invisibly.

Grain texture – Matching the wood grain pattern is also important for seamless repairs. Look for fillers with additives that help recreate the floor’s grain.
Drying time – Pick a filler with a fast drying time so you can sand and recoat the repair area quickly.
Sandability – The filler must be easily sandable to feather out and smooth the patch after drying.

Stainability – Choose a filler that accepts stains if you need to re-stain the repair.
Adhesion – The filler should bond tightly to the wood for a long lasting repair.
Shrink resistance – Minimal shrinkage as the filler dries prevents cracks and voids in the patch.

Solvent vs Water-Based Wood Fillers

Wood fillers come in two main types – solvent-based or water-based. Here’s how they compare for hardwood floor repairs:

Solvent-Based Wood Fillers

Made with lacquer, epoxy or urethane resins dissolved in a solvent like lacquer thinner.
Offer very strong adhesion to wood surfaces.

Dry extremely fast, allowing repairs and recoating to be completed quickly.
Produce low odor and shrinkage.
Sand easily when cured for an invisible finish.

Work well for filling small nail holes and flaws in hardwoods.

Water-Based Wood Fillers

Made with water-soluble polymers like polyvinyl acetate.
Lower in VOC emissions compared to solvent-based.

Require longer drying time before sanding and recoating.
More prone to shrinkage as the water evaporates.
Harder to sand than solvent-based fillers.

More suitable for filling cracks and gouges rather than small defects.

Is wood filler better than wood putty?
