How To Keep Wood Filler From Drying Out

When it comes to wood filler, the first thing you need to do is keep it moist. If filler dries out, it will not bond properly with the wood and may even start to shrink. Avoid direct sunlight if possible as this will also dry out the filler.

In addition, be sure to repair any cracks or damage in the wood before filling them in – otherwise, water may seep into these spaces and cause the filler to rot. Finally, make sure that you use a quality wood filler that is specifically designed for repairing wooden surfaces.

Doing so will ensure that your project stays healthy and durable over time.

Keep Filler Moist

If you are using wood filler to patch up small cracks or holes in your concrete, be sure to keep it moist. Mix the filler with a little water every time you use it to make sure that it stays wet and prevents drying out.

You can also spritz the filler with a mist bottle after each application to keep it wet. If your filler starts to dry out, simply mix some fresh water into it and apply as usual. Do not pour too much filler onto the surface of the concrete; just enough to cover the hole or crack.

Let the filler dry for hours before applying another coat of cementitious material over it. Patching up small cracks is one thing; trying to fill larger gaps will require more than just wood filler. To fill large gaps, you may need to use a grout kit or hire an professional contractor to do the job for you.

Be sure to read the directions carefully before starting any repair project so that you don’t end up doing more damage than good. By following these simple tips, you can prevent wood filler from drying out and becoming unusable.

Keeping wood filler moist is important to prevent it from drying out and cracking. You can keep your filler moist by using a water-based sealer or wetting it down with water after each use.

Using A Dehumidifier

If you are noticing that the wood filler is drying out, there may be a few things you can do to help. One way to prevent the filler from drying out is to use a dehumidifier.

Dehumidifiers work well in both small and large spaces, so they can be a great option for keeping your wood filler moist. When choosing a dehumidifier, make sure it has the correct wattage for your space and the amount of moisture you need to control.

To use a dehumidifier, check the manufacturer’s instructions first. Once you have chosen and set up your dehumidifier, be sure to follow the instructions carefully to avoid damage or problems.

Prepping Your Wood Filler For Storage

Before storing your wood filler, make sure to clean it and dry it completely. If you have any water left on the filler, it will cause the surface to crack and form a mossy growth.

Store your filler in an airtight container so that the moisture doesn’t reach the wood below. Make sure the filler is leveled before storage and avoid stacking it too high. If you do stack it, avoid putting anything heavy on top of the filler; this can cause cracks in the surface or even weight loss over time.

When storing your wood filler, keep in mind that it will need to be refilled every two to three years depending on its usage. Be sure to label your container with the date of purchase and contents for easy retrieval when needed. Finally, use a damp cloth or sponge to wipe down any dust or dirt that may have accumulated during storage.


If you want to prevent wood filler from drying out, it is important to keep the filler well-mixed and moist. Additionally, make sure that the filler is kept in a cool, dry location.
