Sometimes the wood around your home can get cracked, dented, or chipped. Luckily, a wood filler can help fill all kinds of blemishes in the wood.
Thus, you can use it for many different projects, such as filling holes in hardwood, plywood, particleboard, or even concrete blocks.
Furthermore, a Wood filler is commonly used in the construction industry. For this reason, many handymen have asked: Can you screw into wood filler?
To start, yes, you can screw into a wood filler; however, not all wood-filling materials are sturdy enough to be screwed or drilled into. Below, we have discussed everything you need to know about screwing into the wood filler and the best materials.
What is Wood Filler?
Wood filler is a type of wood putty commonly used in the woodworking industry to fill cracks, holes, and other imperfections in the wood. It’s handy for so many things, such as repairing furniture and creating everything from a do-it-yourself shelter to a wall of customized art.
The best wood filler is an epoxy-based wood filler that is dry-mixed using the right water and epoxy resin ratio.
Can You Screw Into Wood Filler?
The simple answer is YES! Screwing into wood filler is a common practice in the woodworking industry. You can screw wood filler with a small pilot hole after it has cured well.
Nevertheless, the process of drilling and screwing into wood filler is one of the most common household tasks. So you must know how to do it right.
Start with a pilot hole that is the same diameter as the wood filler, then drill the pilot hole into the wood filler using a pilot bit.
While screwing and drilling into epoxy-based wood fillers is possible, you will need to use the right technique for the best results. If you drill too deep, you risk drilling through the wood, which could cause cracking and damage to your project.
To drill and screw into a wood filler, you need a drill bit that is the correct size for the filler. Some of the best wood filler bit sizes include:
- 1/4″ bit: Perfect for drilling into large pieces of firmer wood such as pine
- 1/2″ bit: Perfect for drilling into medium-firm wood such as fir
- 5/8″ bit: Perfect for drilling into medium-firm wood such as cherry
- 1″ bit: Perfect for drilling into softwoods such as oak

4 Steps on Applying Wood Filler for Screws
Here are the steps you need to know when screwing or drilling into the wood filler.
Step 1: Surface preparation
When working with food filler, you will need to clean the surface thoroughly you intend to fill. Cleaning helps get rid of stains, loose paint, and any wood chunks.
Step 2: Sanding rough edges
It is important to sand off all rough edges, after which you can use a tack cloth to clean off debris.
Step 3: Apply wood filler.
Use a putty knife to apply your wood filler and press it into the area that needs filling. Slightly overfill to compensate for the filler shrinking or losing its shape.
Step 4: Allow the filler to dry and cure
The filler needs enough time to dry and set for it to hold the screws in place. The minimum time for drying should be 20 minutes to several hours.
Just make sure not to rush this process. Once the filler has completely dried, sand off the uneven edges.
Tips for Wood Redrilling Screws After Filling Holes
Redrilling screws into a wood filler requires a combination of patience and accuracy. Nonetheless, there are many ways to fill a hole for redrilling screws when you want to make your wood usable again.
Some of the quickest ways to fill a hole in the wood include:
- Use of wood filler
- Using sawdust and glue
- Using wood plugs
Thus, choosing the best filler that will not get damaged when redrilling is a good idea. For best results, use a wider diameter screw than the original one.
Is wood filler as strong as wood?
Tests on wood fillers have shown that they don’t hold the same standards as real wood. Thus, wood fillers and sand fillers are compounds used to increase the dimensional stability of any material.
Many different types of wood fillers are available today, each with its unique properties. Every type of wood filler contains a certain combination of synthetic resins, petroleum-based binders, and additives to promote dimensional stability.
Why is it not a good idea to drill screws into Wood Glue?
Drilling screws into wood glue is a bad idea and a very dangerous job. It can cause injuries to the worker, and in some cases, the damage to the structure may be permanent, given that the screw may stick to the wood glue itself.
Can You Reuse Screw Holes In Wood?
You can reuse screw holes in wood as long as they are small enough for the screw placed inside the hole. If the holes are jagged or too loose, they will not secure the screw once it is screwed into place. If you don’t have enough room to place another hole, you can always fill the hole with a quality wood filler, let it cure, and use it with a different screw.
Will Epoxy Wood Filler Hold A Screw?
Yes. Epoxy wood filler is the hardest type of wood filler available on the market. When this type of wood filler dries, it hardens to the surface of real wood, making it easy to sand, paint, nail, and screw. If you’re looking for a wood filler with the structural capacity to hold screws and heavy objects, epoxy wood filler is the best way to go.
Can I screw into Polyfilla?
Yes. Polycell Deep Gap Polyfilla can fill deeper holes, up to 20mm, in one application. Easy to sand for a smooth finish. Fills holes up to 20mm and accepts nails or screws.
It is possible to screw and drill into a wood filler. However, every wood filler varies and is used for various applications like filling gaps, cracks, and holes.
So it is essential to take note of the type of wood filler and the application you’ll be using it for.
