Wood filler is a great way to repair cracks and holes in your woodwork. However, if you don’t know how to use it properly or are working with an older can of wood filler, there’s a good chance it will dry out before you can use it up.
But don’t worry! There are several ways of keeping your dried-out wood filler from turning into dust and wasting your hard-earned cash.
How do you moisten dry wood filler?
If the wood filler is hard and dry, you can use a damp cloth or damp paintbrush to “rehydrate” it. You can also use an old sponge that has been dipped in water, which will absorb the moisture from the air and create a soft “damp” texture.
You could even consider using an old sponge with a touch of dishwashing liquid for extra tackiness!

Can you add water to dried out wood filler?
The word “ceramic” is used to describe the material in the early stages of production. Ceramic is a trademark of the company Master Bond.
When the polymerization reaction is complete, the material is heated to about 300 degrees Fahrenheit, and then it is poured into molds.
The molds are usually made from aluminum or steel block and are designed with surface cavities that allow for easy removal of cured composite filler once it’s cooled down to room temperature (about 20 minutes).
How long does wood filler last after opening?
Keep your wood filler sealed until you’re ready to use it. Even when the package is opened, it can last for years if they are stored properly.
If you keep the wood filler in an airtight container and away from moisture, it should stay good for a long time. Wood filler will dry out over time, so be sure to check the expiration date on your product before using it.
How do you stop wood filler from cracking?
A few simple steps will keep your wood filler from drying out:
- Wipe away excess filler with a damp cloth after you’ve applied it to the cracks. You don’t want to leave any extra behind, and the damp cloth will prevent that from happening.
- Don’t use a wet rag or towel to wipe off your wood filler. The water will get into your wood and create more problems, not solve them!
- Use a cloth that isn’t too damp either—you want just enough moisture on it so that when you wipe off some of the excess filler, there are still enough tiny fibers of glue left in place for good adhesion.
How do you refresh wood filler?
Here are a few ways to refresh your wood filler:
- Add a few drops of water. If it’s in a container, simply add one or two drops of water to the filler and stir it up until it’s moistened again.
- Use a damp sponge or cloth to apply the wood filler onto surfaces in need of repair, then allow it to dry before sanding and finishing (ie, applying varnish or paint).
- Spray the surface with water using an ordinary spray bottle filled with warm water; this will not only soften the filler but also clean off any dirt that might be clinging to it as well. Use caution when spraying—you don’t want too much moisture!
Can you thin down wood filler?
You can thin wood filler with water, but you need to be careful. If you use too much water, the glue will not hold together and it will fall apart.
One way to avoid this is to put your wood filler in a container and then pour some water over it. You can mix the glue around with your hands or with a brush until it becomes smooth and spreadable again.
If you want to use wood filler as a primer for painting, then either add more sanding dust or use less solvent when mixing up your batch of wood filler (or both).
Sanding dust makes the mixture less viscous so that it spreads better under coats of paint while adding more solvent makes them harder to spread out properly on the surface being patched up.
Wood fillers come in many different types: epoxy-based compounds are best for filling cracks; urethane compounds are great for patching holes; acrylics make for good sealers; oil-based fillers seal well but aren’t recommended unless they’re used indoors—they tend not to adhere well outdoors due environmental factors like temperature changes (which cause expansion/contraction) or moisture content changes (which cause both physical contraction/expansion along with chemical reactions between certain types of fillers).
How do you rehydrate putty?
Rehydrating putty is as simple as adding water to it. Start by adding a few drops at a time, then let the putty absorb the moisture before adding more.
If you add too much water at once, it will cause the putty to become mushy and unusable. If your filler is too dry, add more putty until it reaches your desired consistency.
Are wood putty and wood filler the same?
Wood putty and wood filler are different names for the same material. Both are used to fill holes, scratches, and cracks in wood.
The main difference between them is that wood putty has a higher binder content than wood filler. This makes it softer and more flexible, so it can be easily shaped with your fingers while you’re applying it to the surface of a piece of furniture or another item in need of repair.
Hopefully, this article has helped clarify the differences between wood putty and wood filler. While both materials can be used for filling holes in wood, there are important differences.
Wood filler is best for small jobs that don’t need any finishing work on the surface of the wood being repaired because it dries to about twice its original thickness after drying time passes.
On the other hand, wood putty can be sanded down with water or another solvent if necessary before painting over its surface once dry enough so no cracks or wrinkles remain visible anymore beneath paint layers applied later on top!
