will wood filler stick to plastic?

plastic wood filler enthusiasts! You’re looking for a way to fill that ugly crack in your favorite piece of plastic furniture, but you’re not sure if it will work.

You’ve heard good things about wood filler and how it can be used on any surface—but is it really safe to use on plastic?

The answer is yes (and no). As long as you follow some basic guidelines, you’ll be able to successfully fill the gap without damaging your beloved table or chair.

Can you use wood filler in plastic?

Wood filler is a great way to fill holes and cracks in plastic. It can also be used to repair plastic. Wood filler is easy to use and sand, so it can be painted after it dries.

Wood filler is especially useful for filling small holes in plastic, but if you want to fill larger areas of your project, you may need a different material like epoxy resin or another type of glue-based solution that will hold up under pressure from repeated use.

How do you use wood filler on plastic wood?

You’ll need a putty knife to apply the wood filler, and a wet sponge to smooth it out. You can also use a rag to wipe off excess wood filler.

Let the wood filler dry before you sand it down, which you can do with sanding sponges, sandpaper or files.

Is wood putty the same as wood filler?

Filler, putty, and wood filler are all different names for the same thing: a type of material that can be used to fill in holes or cracks in wood.

Wood fillers are not as flexible as putty, but they’re more rigid than fillers. They’ll stick to both plastic and wood without any problems—so if you have a big hole in your shelf (or any other project) that needs filling up with a solid substance that won’t fall out after it dries, this is the way to go!

Can you sand plastic wood filler?

You can sand plastic wood filler, but if you do it incorrectly you may create some holes in the surface of your project.

If you want to avoid this, try using a sander with varying grades of sandpaper (i.e., 80 grit, 150 grit, and 220 grit). Start with the highest grade and work your way down until all traces of the plastic filler are gone.

Don’t sand too much at one time; doing so could melt or crack the plastic filler underneath. Also, avoid going too slowly or too quickly; either will cause tears that are difficult to repair afterward. Finally, don’t use any pressure when sanding—this will only lead to more cracks and tears in your project!

How do you fill holes in plastic?

  • Use a putty knife to fill the hole and create a smooth surface.
  • Fill the hole with wood filler, then let it dry for about 24 hours or until it’s completely hard (this may take longer if the plastic is particularly thick).
  • Sand the wood filler until it’s flush with the surface of your plastic, then wipe away any excess using a damp rag or paper towel—if you don’t sand away excess wood filler, this will leave an unsightly raised edge around your filled patch that can be difficult to sand down again later on in case it needs more work done on it later down the line!

How big of a gap can wood filler fill?

The maximum size of gap wood filler can fill depends on the type of wood filler you’re using.

For example, in the case of polyurethane-based wood filler, it’s best used to fill gaps up to 1/4″ in width.

This means that if your gap has a width greater than this amount, then a different type of wood filler should be used instead.

In addition to this, while it can typically fill gaps up to 3/4″, this is only possible if they are not very deep or long.

If your gap is deeper than 3/4″ or longer than 2″, then it would be best not to fill with polyurethane-based wood filler as its application could prove difficult and potentially messy (see below).

Does wood filler dry hard?

There are a few ways you can tell if your wood filler has dried. If it’s dry, it will feel hard and smooth, but if it still feels sticky or soft, then you need to wait longer for it to dry.

Another thing that indicates whether or not the wood filler is dry is how much time has passed since you applied the filler.

If you have waited long enough for the wood filler to dry, then there will be no bubbles or loose clumps in your project when you look at it from different angles.

If you want to speed up the drying process of your wood filler application, try placing a fan near where you’re working so that air can flow through and help dry out all of those wet bits of glue faster than normal!

After waiting 24 hours (or whatever amount of time was recommended by whoever told me this), I went back over my project with sandpaper just like they said they would do on TV shows about home improvement projects – only instead of using an electric sander like they had done on their show because they were professionals with Lotsa money (and maybe even less common sense), I used an old piece

Can you apply wood filler with your fingers?

You can apply wood filler with your fingers, but it’s messy. Wood filler is a paste-like substance that dries and hardens when you apply it to a surface.

It comes in different textures, so you’ll want to use a putty knife if you want to spread the wood filler evenly over large areas like big wooden planks or furniture.


We hope that we’ve answered your question about using wood filler on plastic! It really is a great idea and can help you save money by repairing broken or cracked pieces of furniture.

If you still have any doubts about whether wood filler would be suitable for your project, just remember that it is not only cheaper than buying new materials but also much easier to work with than most other types of adhesive. We recommend giving it a try before deciding on anything else!
