If you are using MDF, a fiberboard that is often used in furniture or cabinet construction, you will need to fill the voids left by the wood fibers with a filler. MDF will not have knots or other natural variations like most wood products, so finding something that is the same texture and color as the surface can be difficult.
Some of these cheaper fillers may also cause lingering odors instead of “filling” it up with their odorless compounds.

How to Fill Nail Holes in MDF Trim
If you are looking for a way to fix the cracks in your MDF trim, there is a way to fill them. The first thing that you may want to do is prepare the surface. You can do this by sanding it until it is smooth and then wiping it down with a dry cloth. After that, apply some glue or wood filler to the crack itself. It’s best to have some wood glue on hand and then let it sit for at least 24 hours before putting any pressure on it or using the piece of furniture.
1. Sand the Holes
The first thing that you will want to do is sand down the nail holes. Sanding the surface of your MDF can help you get rid of discoloration and remove any remaining pieces of nails or screws. You may even want to use a grinding tool to get off some of the rough parts and make it smoother.
2. Clean the Holes
When you are done sanding the holes, you will want to wipe the surface down with a dry cloth. This will get rid of any dust or dirt that may have gotten on the material.
3. Apply the Wood Putty
Now that your surface is clean, you will want to apply some wood putty. You’ll want to use a paste putty that is made of wood filler and water. This will fill the voids in the nail hole while also giving you a smoother surface when you are done.
4. Sand the Holes and Repeat
After the wood putty has dried, you will want to sand down the parts of it that are still visible. The wood putty that you apply will not be smooth, so sanding it down will allow for a smoother finish. This can also help remove any excess plastic or wood filler that may have seeped out with the putty.
Mistakes to Avoid, Tips & Tricks
There are several precautions that you will want to take when you are working with MDF so that you do not damage it and end up wasting a lot of time. Although MDF is a great material, it can be damaged easily if you do not take precautions. Some of the things to watch for include:
Check for any grooves in your MDF before you apply a filler. The grooves may have been made by the manufacturer on purpose or they may have been created when the boards were stacked on top of each other. If they are on the same side of the board, you should fill the grooves with your filler.
When you are using filler in MDF, make sure that it is dry before you apply any color. If it is not dry enough, it may cause damage to your MDF if you paint over it. Alternatively, if it is too dry and puffs up as you apply a primer or color over the surface, this may give you a rough surface texture rather than a smooth finish.
You should also check to make sure that your MDF is not warping. If it is, this may be a sign that it has absorbed water because the water can cause swelling and cause the MDF to warp.
The last thing you want in MDF is for the surface texture to look too rough. If you notice any texture in there, this could be caused by either a rougher surface texture from your filler or a dry application of filler or primer.
