    Wood Fillers & Putties Frequently Asked Questions

    How long does wood filler take to dry?

    The drying time for wood filler depends entirely on the type of filler you are using, the depth of the repair, and the ambient conditions like temperature and humidity.

    • Ready-Mixed / One-Part Fillers: These fillers harden as the water or solvent within them evaporates. For small repairs, they can be touch dry in 15-30 minutes and sandable in 1-2 hours. However, deeper repairs may need a full cure time of 24 hours or more, especially in colder temperatures.
    • Two-Part Fillers (Epoxy or Resin): These fillers harden via a chemical reaction, making their cure time much more predictable. You typically have a working time of 5-15 minutes before the product starts to harden. They are often sandable within 30-60 minutes and reach their full cure and maximum strength within a few hours.

    Always check the product's packaging for the manufacturer's specific instructions, as this will provide the most accurate guidance.

    What is the difference between wood putty and wood filler?

    Wood putty is typically used for filling small imperfections after the wood has been stained or finished, as it does not harden in the same way as filler. It is often non hardening or semi hardening, making it ideal for minor touch ups. Wood filler, particularly our epoxy wood filler, is designed to harden completely. It is structural, can be sanded, and is suitable for filling larger holes, knots, and areas where rot has been removed before you apply a finish.

    Can you stain wood filler?

    This is a very common question, and the answer is nuanced: most standard wood fillers do not accept wood stain in the same way as real wood.

    Once cured, wood filler becomes a non-porous, plastic-like material. When you apply stain, it will likely be much lighter on the filled patch than on the surrounding wood, resulting in a noticeable, mismatched repair.

    Here are the best strategies to get around this:

    • Use a "Stainable" Wood Filler: Some specific fillers are formulated to be more porous and accept stain better than others. While still not a perfect match, they provide a much better result.
    • Match the Filler Colour: A more reliable method is to choose a filler that is already coloured to match the final stained appearance of your wood. Many brands offer a range of wood tones.
    • Paint Over the Filler: The most common professional solution is not to stain, but to paint. Once the filler is sanded smooth, apply a primer and then paint the entire piece. This completely hides the repair and gives a uniform, consistent finish.
