Wood filler is a type of putty or plastic wood which is used on wooden surfaces before finishing. It’s made up of wood dust, pigment, a diluent and a binder. Once dried, it seamlessly blends into your surface, creating a perfectly smooth, coherent exterior.
Wood fillers typically dry within 20 minutes to two hours, depending on the product and depth of application. Once cured, they can be painted, varnished, or stained to match your finish.

Frequently Asked Questions
Yes. Once fully dry, most fillers can be sanded smooth (120–180 grit) and painted or stained. Solvent-based fillers absorb stain more evenly, while water-based fillers take paint beautifully. Always seal with a compatible primer or varnish for longevity.
Firstly, it is imperative that you prepare the area you are looking to fill. Sand inside the area and then clean off any dust, which could impede the filling process. Using the correct tools (a putty knife, which can be found in our accessories section), begin applying the wood filler.Â
Fill the hole or gap completely, then level the surface with a filling knife or blade. Once the putty is fully hardened and dried, you can proceed to paint.
While often used interchangeably, learning which product is best for your project is the key to a great finish.
Wood Putty
Wood putty is a filler that is applied after staining or varnishing your surface to avoid damaging the raw wood or timber. It’s an oil-based compound that resembles soft clay. Wood putty, therefore, requires a putty knife for application due to its dough-like texture. Some putties harden on their own, while others need a hardening agent. Wood putty is best used on outside surfaces as it is less susceptible to the elements.Â
Overall, it is more cost-effective than filler because it lasts longer. However, it does have a longer drying time, and its penchant for acquiring dust can lead to a darkened appearance. It is ultimately more versatile due to the vast range of colours available.
Wood Filler
Wood filler is to be applied before staining or finishing your wood piece. Wood filler is a superior option for large holes or cracks, as it is made to be formulated for different surfaces. Typically neutral in colour, wood fillers can be tinted or dyed to fit your surface.Â
Best reserved for interior use, wood filler is versatile but lacks adhesion and is prone to shrinkage. Its greatest proponent is its fast-drying properties; it will begin to dry in as little as 10 minutes after application.
When sealed with paint or varnish, interior fillers last 10 years, and outside applications can last 5 years, depending on exposure. High-quality epoxy fillers can outlast the surrounding timber when maintained properly.
Apply filler in thin layers, letting each dry before adding the next. Clean the surface of dust and moisture first, and avoid applying it in very cold or humid conditions. Using a flexible, trade-grade filler reduces the risk of movement or shrinkage.
Choose a two-part epoxy filler like Metolux 2-Part or Timbabuild EHB60. These create structural repairs that won’t crack or shrink, making them ideal for window sills, door frames, or decking edges.
Yes, once fully cured. Two-part epoxy fillers support fixings without crumbling, making them ideal for refitting hinges or handles. Single-part fillers are best for cosmetic surface repairs.
