How to Make Wood Filler Dry Faster

There are several ways to make wood filler dry faster. It is important to note that wood filler comes in either water-based or solvent-based varieties. Solvent-based wood filler is dependable for both professional woodworkers and home DIY projects. However, recent advances in the technology that is used to create water-based wood fillers have produced a product that performs just as well as its solvent-based alternative. Another positive aspect of water-based wood filler is that has less of a negative impact on the environment.

Step 1 – Filling the Hole

Filling the hole correctly is an important step. Methods that accelerate dying times can cause wood filler to shrink if it hasn't been applied properly. Make sure the hole or crack you are going to fill has been cleaned and is free of debris. Getting the dust out is highly important because the surface needs to bond with the wood filler before steps can be taken to dry it faster.

Step 2 – Application

Apply the wood filler to the hole and press it in tightly to the affected area. Applying the layers in thin coats will help the wood filler to dry faster. The thicker the layering, the more water there is to be absorbed and the drying process will inevitably take longer.

Step 3 – Layering

If a high build hasn't been achieved, simply carry on laying the wood filler as thinly as you can. Although this may seem to be a more drawn-out process, it will eventually aid the drying time. Only lay on a fresh thin layer once you are certain that the previous layer has hardened.

Step 4 – Temperature

Using wood filler in a warmer room will help the filler to dry faster. Colder atmospheres create damp conditions and the warmer the temperature in the area where you are working, the better the chances are of the wood filler drying faster. If you have radiators close to the area being filled, switch them on to promote a warmer environment.

Step 5 – Warm Air

You can also speed up the process of drying by using a warm air supply. Something like a hair dryer or a heat gun aimed toward the filled area will assist in reducing the drying time.

Step 6 – Mixing

If you are mixing the wood filler with an epoxy resin, you can add a little more hardener to your mix. While this will speed up the drying time for your wood filler, you must be aware that it will start to harden as soon as it is mixed so you will need to act quickly. The more hardener that is added to the mix, the less time you have to apply it.

Step 7 – Homemade

You can always opt for making your own fast-drying wood filler. All you will need is some quick-drying wood glue and some fine sawdust filings from your stock wood. Mix the two together on a disposable surface and fill the crack or hole in your wood. The quick-drying wood glue will promote a faster drying time.
