One of the biggest issues with hollow core doors is that they can easily get a hole in them. Then, what do you do? No one wants to replace an entire door, right? Well, I am going to show you how to quickly and easily repair hollow core door holes with just a few simple items.
The materials that you will need to repair hollow core door holes are as follows:
- Utility knife or blade
- sandpaper or block (120 grit and fine)
- paper towels
- can of Great Stuff Door & Window foam insulation
- All Purpose Bondo filler
- putty knife
- Paint for touch ups.
Now, let’s get to it. 🙂
Initially, these were thought to be great alternatives to the spring version that mounts on the base boards. They look nice and they are out of the way. But there is one big problem with these. They tend to put holes in hollow core doors.
Why? Well, the part that connects with the door does so on the hollow part. If it connected with the solid frame on the edge of the door, there wouldn’t be an issue. Unfortunately, many of us learn this lesson after it is too late. But not to worry, we can fix those ugly holes very easily.
How to Repair Hollow Core Door Holes
Step 1 – Remove any loose pieces from around the hole. Use your utility knife if needed.
Step 2 – Stuff some paper towels down inside the hole. This will provide a ledge of sorts for the foam insulation to sit until it is dry. Otherwise, the foam would just fall to the bottom of the door.
Step 4 – Using a blade or your utility knife, remove the excess dried foam.
Step 5 – Carefully cut back the dried foam until a slight recessed area is left to allow space for the Bondo.
Step 6 – Mix the Bondo using about a teaspoon amount of bondo with 2″ of hardener.
FYI: This is the Bondo that I used. I bought it at Lowes. Just to let you know, this stuff has a pretty stronge smell. If you are working in a closed room, open a window to allow the smell to ventilate. If you are going to be working in an open area, you may want to weigh the benefits of using Bondo with the smell. If you don’t want to deal with the smell, I would suggest using spackle. However, in my experience the Bondo gives a stronger result.
Step 7 – Smooth bondo over the hole area. This will set up very quickly, so be prepared. (By the way, I am just using a popsicle stick for this)
Step 8 – Wait a few minutes (until the bondo begins to thicken). Then, use the putty knife to scrap the excess bondo away.
It should be mostly flush with the door. You will notice that it is not perfect yet. There will likely be a few pitted areas still.
Step 9 – Sand the Bondo down as smooth as possible. Don’t worry about getting the pitted areas smooth, yet. Just make sure that it is all flush with the door.
Step 10 – Mix a small amount of bondo and smooth it over the pitted areas. (Just like icing a cake). Allow this to dry completely. That should take a couple of hours.
Step 11 – Sand (using the fine grit sanding block) until it is completely smooth and flush with the door. (Tip: The sanding blocks will help to get a better/flush result than the sandpaper will).
The best hinges for hollow core doors is still the base molding spring stops, (as seen on the door in this foreground) and not the hinge pin stops (as seen on the two doors in the background).
Now, if the hole in your door was caused by a hinge pin stop, replace it with a different type. If the location of the door prevents another type being used, the best solution is to place additional hinge pin stops on the remaining hinges as well. That way the pressure can be distributed along all three or four hinges instead of focusing on just one spot. (Notice that the two doors in this image have hinge pin stops on both the top and bottom hinges).
