Rustic Wood Floor Supply —
Fillers That Finish
Your Floors Strong

Fast-drying, color-matching fillers made to smooth, seal, and strengthen every wood floor project.

Restore Your Floors with Our Reliable Wood Fillers

Cracks and gaps make wood floors look unfinished. Dirt can get stuck in those spots. We get how important it is to have a filler that dries quickly and sands smoothly. Our hardwood wood floor fillers dry fast, usually in 20 to 30 minutes. They sand down smooth, leaving no rough edges. 

Rustic Wood Floor Supply has many colors. When there’s no perfect match, we help you mix fillers or suggest trusted products like wood doe. Our hardwood floor crack filler doesn’t stretch with the wood, but it resists cracking. That means your floors stay beautiful for years.

Trust our fillers to bring your floors back to life with ease and precision.

Seal The Gaps with Premixed
Wood Floor Fillers

A great floor loses its charm if filler lines show through. We’ve seen it happen. At Rustic Wood Floor Supply, we know that a smooth finish starts with the right match. Our premixed wood floor fillers come in reliable, natural shades that blend with most flooring types.

But sometimes, your floor’s tone is one-of-a-kind. We’re here for that too with custom-match guidance. Our fillers are stainable, easy to apply, and designed to stay in place. No filler should ever hold up your project, and ours won’t.

Match Any Wood Tone With Our Customized Mixing Fillers

We’ve all been there, standing over a beautiful hardwood floor, only to realize none of the premixed fillers work. The color’s off, the finish looks forced, and the whole job feels stuck. We know how frustrating that is. That’s why we turn to mixing fillers. 

By blending your own fine sanding dust with a specialty filler base, you create a custom blend made straight from the floor itself.  Stains well, dries fast, and looks like it was always there.

Use with:

  • Pallmann Pall-X Filler
  • Loba EasyFill Pro

Mix smarter. Match better.
