7 Best Materials for Filling PVC Trim Nail Holes

There are a variety of materials that can be used in order to fill PVC trim nail holes. Let’s take a look at all of the possible materials right now.

1. Epoxy PVC Nail Hole Filler

Epoxy PVC Nail Hole FillerThe best material to use for this task is a two-part epoxy PVC nail hole filler. This is a very special type of two-part epoxy that is designed specifically to be used with PVC. Technically speaking, this is a type of adhesive or glue.

It features properties that allow it to properly bond with the plastic, and it also doesn’t shrink or expand. Moreover, it’s also extremely easy to sand down. That said, it’s a little messy because you have to mix it, but it does produce by far the best results. Also, you can usually find PVC nail hole filler in the exact same color as PVC.

2. Two-Part Epoxy

If you don’t have a special nail hole filler for PVC, you can always use basic two-part epoxy. This type of epoxy bonds very well with plastic, it’s extremely durable, waterproof, and it dries fairly quickly too. Two-part epoxy also should not expand or shrink, thus making it perfect for filling nail holes.

That said, you do want to try to find epoxy that matches the color of the PVC trim you have. Moreover, do be aware that not all epoxies can be painted over, which may be an issue.

3. Silicone Caulking

Silicone CaulkPerhaps one of the best alternatives for filling PVC trim holes is silicone caulking. Silicone caulking is very easy to use thanks to the small nozzle at the front of the tube. Therefore, inserting it into PVC trim nail holes should be fairly straightforward. Moreover, silicone caulk should bond just fine with the PVC, and it also shouldn’t expand or shrink too much. The caulking may shrink a little bit as it dries, but you can apply a second layer if need be.

Caulking is of course heat resistant and waterproof, so that is a bonus. Moreover, silicone caulking is also white in color, which should match white PVC trim.

4. Vinyl Spackling

That said, using this material can be a bit messy.

5. Wood Putty/Filler

Although this is certainly not the first material that we would recommend using for this task, wood putty or wood filler will do the trick in a pinch. Wood putty or wood filler should not shrink or expand, so it should do a good job at filling the hole, plus it can also be painted over, which for many people is going to be a bonus.

That said, putty and wood filler might not create the best bond between it and the PVC.

Joint compound is not the most durable material out there, and it isn’t waterproof either, but the bonus is that it can be painted over very easily.

Therefore, if you plan on painting your PVC trim, then keep the joint compound as an option.

7. Bondo

Bondo is another material of choice for this task. Bondo is specially designed as a filler. It is easy to get into small areas, it doesn’t expand or shrink as it dries, it forms a solid and waterproof layer, and it will adhere to PVC just fine. In fact, besides the PVC nail hole filler, Bondo might just be your best bet.
