While most wood fillers can be stained, some are better than others.

This wood filler can perfectly blend into your floors so you can’t tell that it’s there.

What I Liked:

Another great choice is Timbertmate Wood Filler. This wood filler is great for hardwood floors because of how easy it is to apply and how fast it dries.

When compared to the Stainable Minwax wood filler above, this one didn’t stain quite as well, so it was a little more noticeable in my floors.

That said, I did like that it didn’t shrink as much and it dried super quick.

Whether you have a natural, red oak, or even ebony colored floors ā€“ you can find a wood filler that matches.

This is one of the thickest wood fillers I’ve come across in the years I’ve been woodworking, which can make it somewhat more difficult to spread and apply.

But that also speaks to how durable and long lasting this wood filler is. It also didn’t shrink much when applied, which was nice.

Because it’s a latex wood floor filler, it can be used for both indoor and outdoor applications (which might be handy for some people).

683 Reviews
Abatron WoodEpox Epoxy Wood Replacement Compound, 2 Quart Kit, Part A & B
  • Rotted Wood Restoration
  • Fills and Rebuilds Missing Sections of Wood
  • 100% Solids and Shrink-Free

If you’re dealing with wood floors with major cracks and other structural issues, you’re better off using a more heavy duty filler like this Abatron WoodExpox wood filler.

This is different than every other wood filler I’ve listed so far in that it is an epoxy based wood filler. This means it comes in two parts, that you’ll have to mix before filling.

This is the strongest wood filler you’ll find on this list. If you’re looking for a wood filler for large holes, this is a great choice.

What I Liked:

  • Heavy duty wood filler that’s extremely durable
  • Great for rotted wood because of its strength

What I Didn’t Like:

  • Significantly more expensive than other options
  • More toxic than others
  • Takes longer to dry

My Thoughts:

The Abatron WoodEpox Compound is one of the most heavy duty wood grain fillers you’ll find. This is an epoxy based wood filler, which is great for wooden surfaces like floors because of how durable it is. It’s more toxic than others so it’s important to wear safety gear when applying, but I highly recommend this wood grain filler for your floors.

6. Donald Durhams Rockhard Water Putty – Best Wood Putty

DURHAM’S Rock Hard Water Putty – 4lb Container
  • Water Putty, Makes long lasting repairs in wood, plaster, drywall, stone, tile, concrete and other materials
  • Easy To Use, Use indoors or outdoors must be kept painted on outdoor work
  • Will Not Shrink and Easy to use and ready when you need it – just add water and mix

If you’re looking for a more flexible gap filler, using a wood putty like this one might be your best option.

There are certain benefits of using a wood putty vs wood filler, so this is worth considering.

This wood putty, like others, doesn’t shrink at all ā€“ meaning you don’t have to worry about it not completely filling your gaps or cracks once dry.

You can stain it to match your floors, so it blends in and isn’t super noticeable.

What I Liked:

  • Doesn’t shrink at all
  • Easy to apply with fingers

What I Didn’t Like:

  • Doesn’t stain quite as well as a traditional wood filler

My Thoughts:

This wood putty is a great choice if you’re filling nail holes or other gaps in surfaces that need flexibility. This makes it perfect for deeper holes and gaps. It doesn’t stain as well as others, but it won’t crack later because it never fully hardens.

7. Elmer’s Wood Filler – (I Don’t Recommend)

Elmer’s Products E848D12 Carpenter’s Wood Filler, 1/2 Pint, 8 Fl Oz
  • Ideal for repairing holes, dents, scratches, gouges, and defects
  • Works on any wood, wallboard, molding, or painted surface; for interior use only
  • Paintable and sands easily to a smooth finish

Okay, so there’s one wood filler on this list I don’t recommend for filling wood floors. It’s Elmer’s Carpenter’s Wood Filler.

Don’t get me wrong, this isn’t a bad wood filler in general, it’s just not the best for your wood floors.

I do recommend this wood filler for screw holes and other smaller holes, but not for hardwood flooring.

First, it doesn’t stain well compared to others, which is critical. Secondly, it shrank a decent amount, so you’ll have to apply more once your first application dries. Lastly, it’s not nearly as durable as others.

There is one good thing though ā€“ the price. This is the cheapest wood filler you’ll find so if you just need the cheapest and most budget friendly, this is your best option.

What I Liked:

  • Cheap, cheap, cheap

What I Didn’t Like:

  • Doesn’t stain well
  • Not durable enough for floors
  • Shrinks once dried

My Thoughts:

Elmer’s Wood Filler is a decent wood filler for several projects, but I don’t recommend it for hardwood floors. This filler didn’t stain super well, it shrinks a ton, and it isn’t nearly as strong as others. Unless you need the cheapest option, go with another choice.

What to Consider When Purchasing a Wood Filler for Hardwood Floors

Color & Stainability

I think the most critical thing to consider when purchasing a wood filler for hardwood floors is how well it stains or accepts paint.

Unless you don’t care what your floors look like, this can go a long way in making your wood filler look like wood so it blends in and can’t be spotted easily.

You can opt to purchase stainable wood fillers that easily accept paint or stain to match the surrounding wood, or you can go with a filler that’s already colored and matches your floors.

Either way, the best wood filler will match your floors and blend right in.

Type

There are two main different types of wood fillers that can affect how the filler performs under a variety of conditions.

Water based wood fillers are more common and are often made from real wood fibers, glues, and other components.

These are faster drying, more budget friendly, and easier to apply than a solvent based wood filler.

Solvent based wood fillers are made with more chemicals but they are stronger, more durable, and can withstand more moisture than water based options. These are also more expensive and sometimes require more work to apply.

The type of wood filler you should purchase will depend on your needs.

Are you filling a small nail hole in your floor? A water based filler will probably get the job done!

Are you looking for a wood filler for your deck? Solvent based fillers are likely the better option.

If you’re working on exterior wood, you’ll need a filler that can withstand the elements.

Durability

The durability and longevity of your wood filler is also something you’ll want to look for. Because floors need to withstand daily traffic ā€“ you need something that’s going to last.

Otherwise, over time your wood filler will become less and less strong and eventually crack and come out of your floor.

When it comes to durability and strength, you want to look for wood floor fillers that contain real wood fiber. This will increase it’s strength and ensure it lasts longer.

Alternatively, you can opt for an oil based filler like an epoxy based filler that tends to be stronger.

Drying Time

While the drying time is worth consider, I wouldn’t make your purchase decisions based on this factor alone.

In general, water based fillers will dry much faster than solvent based fillers.

How to Fill Cracks and Gaps in Hardwood Floors

Step 1. Mix Wood Filler

First, you’ll need to mix the wood filler if it’s an epoxy based filler. You can use a putty knife to mix your filler. If you’re using a water based filler, you can skip this step.

Step 2. Apply

Next, apply the wood filler over the crack, hole, or gap in your floor. If you’re using a wood putty, you can use your finger to apply the putty into the crack or gap.

If you’re using a wood floor filler, you can use a putty knife to smooth the filler over your hardwood floor.

You can use your finger to press down on the filler depending on how big the crack or gap is.

Be sure to wipe away excess filler once applied.

Step 3. Let it Dry

After applying your wood floor filler, you need to give it enough time to dry before putting any pressure on the area. The time it takes wood filler to dry will depend on a few factors, but mainly the type of wood filler you’re using. For a water based wood filler, you’ll need to give it a few hours to dry completely. For an oil based filler, it can take over 24 hours to completely dry.

Step 4. Sand

Once your wood filler has dried, you’ll want to lightly sand it down to match the area around it. It’s critical not to sand it too hard, otherwise you might accidentally remove some of the wood grain from your floors also. You want a smooth finish that looks like the wood around it.

Step 5. Stain

Next you can paint or stain it to match the surrounding area. This step won’t be required for all wood floor fillers because some of them will come colored.

Final Thoughts

There’s certainly no shortage of wood fillers available, but finding the right one for hardwood flooring can be slightly more difficult.

You want to look for a filler that can be stained or painted so it matches the floor and blends in.

The best wood filler for hardwood floors is the Mixwax Stainable Wood Filler. It’s a great choice that can be painted to stain to match the surrounding wood floors.

My second choice is the Timbermate wood filler. It’s one of the best wood fillers overall, and it works well on hardwood floors.
