Using Wood Crack Filler: A Step-By-Step Guide
- The first and most important step is to sand and clean the piece of wood or flooring that needs to be filled
- Using a putty knife, scrape the wood filler over the cracks, and then use your finger to push it deeper if you are dealing with a deep hole
- Check the instructions on the filler’s packaging for its dry time and wait the right amount of time for the filler to dry before going over the area with sandpaper
- You can now paint or stain the filler in any color you wish to match the existing wood around it!
Filling Cracks with Glue and Sawdust
If you want to make your own wood floor crack filler, you can do so with some glue and sawdust.
Simply mix the two materials together and apply the paste according to the steps above! This is a great way to ensure you have an accurate wood color match for your repairs.
Fixing Cracks with Epoxy
Expoxy is another type of wood filler that is a useful way to fill cracks in the floor. Unlike a sawdust-based filler, you will need to go out and buy epoxy.
If you are using epoxy, keep in mind that there is an extra step required: Before following the steps above, mix your resin and hardener together to make your epoxy!
Whether you are using store-bought wood crack filler, sawdust filler, or wood crack filler epoxy, a top tip to keep in mind is to work quickly.
These materials dry and harden quickly, so in order to have the best results you need to be as swift as possible.
Another great tip is to slightly overfill the crack or hole. This will allow you to sand down the filler to the perfect points and ensure a smooth and seamless result!
There are some things to keep in mind when using wood crack filler.
The most important is to not sand down your filler too quickly. You need to make sure it has completely cured and hardened and is in a well-ventilated area, as otherwise, you run the risk of crumbling or cracking the filler and needing to make the repair all over again! Make sure to check the dry time on the filler’s packaging for the right instructions.
You should also try to keep the filler off of your skin. Repeated exposure to wood crack filler can cause redness, irritation, and sometimes even non-contact dermatitis.
Therefore, make sure you wear adequate protection when using filler to look after your skin.

What is the best wood filler for large gaps?
An acrylic caulk with silicone filler is the best type for larger holes. This type of formula is thick and durable enough to fill a larger hole with ease, and it is usually sold in large quantities that allow for an adequate amount of product to be provided.
What is the difference between wood putty and wood filler?
The key difference between the two is that wood filler is designed to be used for filling gaps in unfinished wood, meaning it can be sanded, painted, and stained if needed.
On the other hand, wood putty is only suitable for small gaps and holes, and cannot be stained or sanded.
Can you fill large gaps in wood with epoxy resin?
Yes. As long as you seal the bottom of the gap to prevent leaks, you can fill large gaps in wood with epoxy resin.
What kind of epoxy do you use to fill voids in wood?
Liquid epoxy is the best kind of epoxy to fill voids in wood, as the liquid formula sinks right to the bottom of the hole and into the wood – allowing for strong adhesion and a strong bond.
