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.
After the filler dries, it can no longer be molded. Instead, it’s more like the consistency of rock or hardwood.
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
Latex-based alternatives are preferable to epoxies for outdoor use because they require less prep work. 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.
Generally, allowing the filler to dry and cure for at least 24 hours before sanding or staining is best. Following the manufacturer’s instructions for application, drying, and curing times is essential to ensure the best results.
Durability
You should also consider the lifetime and durability of the wood filler. Because of the constant foot traffic, flooring must be durable.
Otherwise, the wood filler for hardwood floors would lose its integrity and start cracking and peeling up from the floor over time.
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.
Oil-based fillers like epoxy-based fillers are another option because of their increased strength.
Indoor vs. Outdoor Use
The best wood filler you choose depends on the task at hand. If you’re working on an inside project, use a filler made for both indoor and outdoor use or a water-based, trowel-ready wood filler.
Use a grain filler designed for outdoor or 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 best for repairing larger holes and gaps in the wood, such as those caused by rot, warping, or insect damage.
Unlike wood filler, wood putty is typically made from a mixture of sawdust and a binding agent, which gives it a more natural appearance that blends in well with the surrounding wood. Wood putty is best for repairing minor nicks, dents, and scratches in wood.
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.
