The length of time for the wood filler to try depends on its type. There are also a lot of other factors affecting the drying process.

Filler Amounts

The amount of filler you add will determine how fast and how evenly it dries. A thinner formula will dry faster, but thicker formulas may take longer to dry.

Using fillers in thin amounts is not recommended so that it would dry easily. Apply a sufficient amount as needed.

Keep in mind that putting it into areas with bigger gaps will require more time and more putty.

Filler Types

Besides filler and putty, there are several existing fillers, such as homemade power, epoxy, acrylic caulk, and epoxy. So choose according to your needs.

The applied mixture and material will determine how long the filler will take to dry. The maximum time for some fillers to dry is 15 minutes.

Dry Time of Oil vs. Water Type Wood Filler

How to Make the Wood Putty and Filler Dry Faster?

When it comes to repairing your home, you want to get it done as fast as possible. Here are things you can do to fasten the process of drying wood putty and wood filler.

1. Layering Thin Layers of Filler

Applying thick layers at a time will take longer. You should apply thinner layers on wood to let it dry up fast. Apply a sufficient amount to get the work done.

Consider adding thin layers until the surface is completely covered. Add another layer as soon as the first layer hardens.

2. Clean Up the Area

Ensure there isn’t any left dirt, dust, and debris before applying it on the surface. It will take longer to dry and produce a bad result.

To speed up the drying process, make use of a towel, sandpaper, or any sander. If a hole is filled with dirt, a screwdriver will help push dirt out of the crevices.

3. Employ Hardeners

You can carefully add hardeners such as epoxy resin to your mixture. Too much mixing may produce a hardener alone instead of a filler.

Mixing fillers with hardeners are done to strengthen the material, but using too much can make it susceptible to breaking. The best way is to use the right amount to make it last.

4. Warm It Up

The sun is part of the drying process of wood, and if the sun is not shining, you have to do your drying with a heater as it will help you dry faster. In addition, you can make use of a hairdryer or an electric fan.

5. Sand It Out

Once you’ve tried everything, consider sanding it out so it will give you a refined look while the applied filler is being dried up. If it is not effective, leave it again to dry under the sun or with a cooling fan.
