Scratches and nail holes are unavoidable when it comes to hardwood floors, so it’s only apt to choose a durable wood filler. If you apply the wrong filler, you expose your flooring to further damage and moisture.
In this article, I will share my picks for the best wood fillers for hardwood floors and provide a comprehensive guide to help you make an informed decision.
Reviews of the Top Wood Fillers for Hardwood Floors
1. Minwax 42853000 Stainable Wood Filler
The Minwax 4285300 Stainable Wood Filler is a two-component product that can be used to fix rotten or decayed wood. Since it’s constructed from wood fibers, the finished product looks like stained wood and can be painted, sanded, and stained like regular wood once it’s dry.
I’ve used it for patching up places where wood decayed or where I installed a new door frame, and it fills those holes like a charm. The ease with which you can fill in floor gaps with this pliable wood filler will astound you.
Plus, the texture is a bit smoother than your standard wood putty, so you can actually mold it by hand if you don’t want to go hunting for a putty knife.
What I Like
- As the best stainable wood filler I've tried, it blends seamlessly with hardwood floors
- The filler's resilience against rain and sun is particularly impressive
- It's great for indoor and outdoor furnishings
- I've found that painting and sanding over it are both hassle-free
- What sets it apart is its authentic wood fiber appearance; it really looks like the real thing
What I Don't Like
- It does tend to shrink slightly when it dries.
- The lack of larger tub options can be limiting if you're tackling a big project
2. Abatron WoodEpox Kit
Now, if you’ve got some serious structural issues with your hardwood floors—like large cracks or significant decay—I’d steer you toward the Abatron WoodExpox Kit.
This WoodEpox resin is a high-strength adhesive that can bond to wood, concrete, and other porous surfaces and is resistant to water, chemicals, and UV rays. The hardener is a catalyst that, when mixed with the resin, triggers a chemical reaction that causes the epoxy to harden and cure.
I found it quite easy to apply and it doesn’t sag, which is always a win in my book. The bond it forms with the existing wood is something to write home about—strong and long-lasting. It retains its original shape and size and never breaks or chips. It has a fantastic twenty-minute operational time.
What I Like
- When I have larger projects, this heavy-duty wood filler is my go-to.
- Easy application; no hassle for me at all
- It's a heavy-duty wood filler

Also, it does a fantastic job of fixing maple, oak, mahogany, light, painted, natural surfaces, and various other surfaces.

The Timbermate Wood Filler is unlike any other wood putty or grain filler for hardwood floors on the market because it is water-based, dries quickly, and takes stains exceptionally well. It can be stored and used for future woodwork repairs.
The stain’s exceptional ease of use makes it an ideal choice even for individuals with limited experience. Cleaning this stain is a breeze, as it only requires a simple mixture of soap and water.
Moreover, it exhibits a strong bonding capability with wood, ensuring a secure and long-lasting adhesion without the risk of drying out or fracturing.
Also, the quality of its consistency is superb. Because it is grain-free and adaptable, it works great for patching damaged hardwood floors and plywood, filling nail holes, and repairing cracks. It’s been a go-to of mine for various woodwork repairs, and I couldn’t be happier with it.

Wood Fillers for Hardwood Floors Buyer’s Guide
Color
Unlike a traditional wood filler, there is a wide range of colored wood fillers to choose from. Choose the best wood filler that is the same color or can be stained to match the adjoining wood.
If you want it to go unnoticed, don’t buy a color that stands out a little if you want it to go unnoticed.
Stainability
The stainability of a wood filler is the most crucial factor to consider when fixing hardwood floors.
You can choose the best wood filler that is already the color of your floors or a stainable wood filler that can be painted or stained to resemble the existing wood grain.
However, the most effective wood filler will look just like the rest of your floors.
Gypsum-Based
Wood fillers made from gypsum [1] can be stained to match the surrounding flooring or wall. Gypsum dust is the main ingredient in this filler, and it should be mixed with water to make a paste.
But let me tell you, once this stuff dries, you can’t reshape it. It becomes as hard as rock.
A gypsum-based filler may not be suitable for use in damp environments due to its susceptibility to decay when exposed to water.
Epoxy-Based
Epoxy wood floor fillers are among the most long-lasting and flexible, so you can use them indoors or out. Combine the two components as the manufacturer directs for the best filler consistency and adhesion.
You can apply the wood epoxy to the damaged area once correctly mixed.
The best epoxy-based wood fillers are ideal for outdoor applications due to their flexibility in responding to changes in temperature.
Latex-Based
When I needed a filler for some outdoor furniture and didn’t want to do a lot of prep work, I turned to latex-based fillers. They’re water-resistant and dry in about an hour.
Filling holes, repairing gouges, restoring rotten wood, and mending outdoor furniture are all easy tasks that can be made more accessible with a latex wood floor filler.
Type of Wood Filler
Cellulose-based wood fillers, gypsum-based, and wood fibers are examples of water-based fillers. They smell somewhat and are easily damaged by water, making them perfect for indoor use.
They dry rapidly, and a soapy solution is needed to clean them. Yet, the vinyl and epoxy compound used in solvent-based fillers makes it a superior choice. They have stronger scents.
However, they adhere securely and can also withstand the elements, so they’re great for outdoor tasks. It may take some time for them to cure and set, and they can be challenging to clean up after.
Time to Dry and Cure
The drying and curing time of wood fillers for hardwood floors can vary depending on several factors, including the type of filler used, the depth and width of the repair, and the environmental conditions.
The curing time refers to the time it takes for the filler to cure and harden fully. This time can vary depending on the type of filler and the environmental conditions.
In my experience, it’s generally a good idea to let the filler dry and cure for at least 24 hours before you think about sanding or staining it. Trust me, you’ll want to follow the manufacturer’s guidelines closely for this. It really does make a difference in the end result.
Durability
Let’s talk about durability because it’s a big deal, especially for hardwood floors that see a lot of foot traffic. I learned the hard way that not all wood fillers are built to last. Some can start cracking or peeling up over time, and that’s not what you want.
You want to seek natural wood look in wood floor fillers if you care about strength and durability. This will fortify it and lengthen its useful life.
I’ve also had good luck with oil-based fillers, especially those that are epoxy-based, for areas that really need to stand the test of time.
Indoor vs. Outdoor Use
The best wood filler you choose depends on the task at hand. For indoor projects, I usually lean towards either a filler that’s good for both indoor and outdoor use or one that’s water-based and ready to apply with a trowel. Indoor fillers are often easier to work with, and if you’re anything like me, you’ll appreciate the convenience.
Now, if you’re tackling an outdoor project, you’ll need a grain filler that’s specifically designed for exterior use to increase the longevity of your wooden floor. Remember that filler for outdoor projects must be resistant to elements like ultraviolet radiation, rain, snow, etc.
Steps to Fill Cracks and Gaps in Your Hardwood Flooring
Step #1: Mix Your Filler
If you’re using an epoxy-based wood filler for hardwood floors, mix it up first. The furniture repair kit can be combined with a putty knife. You can ignore this step if your filler is water-based.
Step #2: Spread it on the Surface
Spread the wood filler throughout the damaged area of your floor. Wood putty can be easily applied into the gap or crack with just your finger.
A putty knife can spread wood floor filler evenly on a hardwood floor. Depending on the size of the hole or crack, the filler can be pressed down with a finger.
Once the filler has been put in, remove the excess filler.
Step #3: Allow it to Dry
It’s essential to wait until the wood floor filler is completely dry before walking on it. The drying time of wood filler is dependent on several elements, most notably the wood filler itself.
It takes a few hours for the water-based wood filler to cure entirely. An oil-based filler may take more than 24 hours for an oil-based filler to dry completely.
Step #4: Start Sanding
After the wood filler dries, you can smooth it out so it blends in with the furnishings. Be careful not to sand too aggressively, or the wood grain on your flooring could be damaged. You should aim for a finish that is as smooth as the surrounding wood.
Is Wood Putty or Wood Filler Better for Hardwood Floors? + Key Differences
Both wood filler and wood putty can be helpful in repairing and restoring wooden surfaces, but the choice between them depends on the project’s specific needs.
Wood filler is my go-to for larger issues like holes or gaps caused by rot or insect damage. I find that it fills those areas effectively and stands up to wear and tear over time.
On the flip side, wood putty has a special place in my toolkit too. Unlike wood filler, it’s usually a blend of sawdust and some sort of binder. The natural look it provides blends seamlessly with the surrounding wood, making it perfect for fixing minor nicks, dents, or scratches.
If you’re repairing larger areas of damage, you need the best wood fillers for hardwood floors, while for more minor repairs, wood putty is more suitable.
| Wood Putty | Wood Filler |
| Indoor and Outdoor use | Indoor use |
| Stays workable | Hardens when dry |
| Oil-based or solvent-based | Water-based |
| Best for finished wood | Suitable for unfinished wood |
FAQ
Can I walk on wood filler?
Wood filler can be walked on, but it’s essential to remember that it may be weaker than the surrounding wood. While it can help fill in gaps or holes and make a surface smoother, it’s not intended to replace or reinforce the structural integrity of the wood floors.
What else can I use to fill holes in hardwood flooring?
To fill holes in hardwood flooring, use colored wax, wood plugs, and a mixture of sawdust and glue. It’s important to note that while these solutions can work well for small to medium-sized holes, they may not be suitable for larger holes or extensive damage to the wood floors.
Can poly fill cracks on flooring?
Polyurethane is not typically used to fill damages in the flooring. While polyurethane can be used as a finish for hardwood floors, it is not recommended for repairing or filling gaps.
Consider using the best wood filler or wood putty to fill nail holes or fill gaps in hardwood flooring.
How can I make my own wood filler for hardwood flooring?
To make your wood filler for hardwood flooring, you can mix fine sawdust from the same type of wood as your hardwood floor with wood glue or wood flour cement in a 2:1 ratio. Mix them until they form a thick paste, then apply it to the cracks.
