how to keep plastic wood filler from drying out?

A lot of people have asked me about the best way to keep plastic wood filler from drying out and becoming unusable. The answer is simple: keep it wet.

But there are other ways to renew and rehydrate your plastic wood filler so that you can use it again and again, allowing you a more cost-effective project.

Can you rehydrate plastic wood filler?

Yes, you can rehydrate plastic wood filler. However, it’s important to know that this process takes a long time. If you have an emergency repair to make, don’t try this method; seek out other options instead.

To rehydrate plastic wood filler:

  • Remove any excess dry powder from the surface of the hardened filler in your container and replace the lid tightly over your container of dried filler.
  • Place a wet sponge on top of your container—don’t get too close or water could seep into it! Leave it overnight and check on it in the morning. You’ll likely see some moisture in its bottom layer; if there isn’t any, add more water until you do see some wetness at its bottom edge (about ¼ inch). For best results with this method, leave your filled container for three days before using it again!

How do you renew plastic wood filler?

To renew plastic wood filler, take your bowl of dried-out filler and add water to it. Mix the filler until it’s smooth and then continue working with the product as normal.

If there is a large amount of dried-out filler in your container, you may want to add more water and mix again before applying it.

If you are able to use this method on a large amount of dried-out plastic wood filler, great! But if not, you’ll need to throw out what is left in the container.

Can plastic wood filler be thinned?

You can thin plastic wood filler. In fact, it’s a good idea to thin it a bit before you use it. That way, the filler will flow more easily into gaps and other small spaces.

You should use water or denatured alcohol as the solvent (the type of liquid used to dilute the dried filler).

You can also use acetone if that’s what you have on hand but make sure to test it first: not all types of plastic wood fillers are compatible with acetone.

If you thin out your plastic wood filler, it’ll take longer for the material to dry and shrink back together after curing.

This means there is more time for cracks and other imperfections to form in your project—so be extra cautious!

Can I mix water with wood filler?

Yes, it is possible to mix water with wood filler.

The amount of water added will depend on the brand and type of wood filler that you are using. In general, you should only add enough water so that the mixture can be spread easily into place.

How do you soften plastic wood putty?

  • Add water. You can add water to the putty to make it more malleable. This is a good idea if you want to create an indentation or other small shape, but don’t want a larger area of filler that’s too big for your project.
  • Use a heat gun or hair dryer on low heat and aim directly at the filler until it softens enough for you to use your fingers in shaping it into place (this works best on smaller areas). If you don’t have access to these tools, try using a heat lamp placed so that the plastic wood is in its direct path of light; this will also soften any dried bits of plastic wood up so they become workable again!

How do you bring wood filler back to life?

First, remove any excess filler from the hole. Next, wet a rag with water and lightly apply it to the surface of the dried-out wood filler.

This will soften up your dried-out filler and allow you to scoop out as much excess material as possible without damaging your project’s finish.

Don’t worry about adding too much; you can always sand away what you don’t need later on!

Once you’ve cleaned up all of your mistakes, re-apply wood glue directly onto top of where your patch used to be (this is why we recommend using a good-quality glue stick instead).

Once again let it dry overnight before sanding down everything so that there are no rough edges left behind after painting/staining over top

How strong is plastic wood filler?

Plastic wood filler is a strong, versatile material that can be used to repair or replace wood. Plastic wood filler will bond to almost any surface.

The only problem with plastic wood filler is that it dries out quickly, which makes it brittle and weakens its strength.

For best results, apply a liberal amount of plastic wood filler to your project before you start working on it so that you have time to sand it down before it dries out.

If you’re using the material for repair purposes rather than as an actual part of your project (such as a door), let the filler dry overnight before sanding it down so that you don’t mess up any work already done on the door itself.

The thickness and quality of this drying time will depend largely on how thickly applied your first coat was—if you applied too much at once then there’s no need for concern here because even if some areas do dry quicker than others due to their proximity or exposure level (such as around windows) then those areas won’t matter since they’ll get covered up later anyway!

Is Plastic Wood the same as wood putty?

Plastic Wood and wood putty are both used to fill holes and cracks in wood. They’re both made from different types of materials, though—plastic wood is made from plastic, and wood putty is made from wood.

Plastic Wood is more durable than wood putty, but it’s also more expensive.


Plastic wood filler is easy to use and has many benefits, but it can dry out over time. This article will help you find the best way to rehydrate dried-out plastic wood filler so that you can continue using it on projects around the house.
