How to Use Ronseal Wood Filler

To commence the process, it is recommended that you gather a pea-sized portion of hardener and a golf ball-sized amount of filler. Mix the two substances thoroughly until the mixture reaches a consistent colour throughout. This will ensure optimal results in your project. This can be easily accomplished in the lid. Before filling the hole, test the filler on a small area to ensure you are satisfied with the colour. Once you are ready to fill the gap, pack enough filler to raise it above the surface and ensure it is filled. Smooth over the filler with a knife before it hardens. You have around 20 minutes to carve or shape the filler before it sets. Once the wood filler has hardened for 30 minutes, it can be sanded, planed, filed, nailed, or screwed. Afterwards, it can be stained, varnished, or painted.

What is wood filler?

Wood filler is a versatile putty-like substance used in woodworking to fill gaps, cracks, and holes in wooden surfaces. Composed of wood fibres or sawdust mixed with binding agents, it provides a smooth finish for painting, staining, or finishing. Wood fillers come in indoor and outdoor varieties, water-based or solvent-based options, and stainable or non-stainable formulations. The application involves cleaning the area, applying the filler, allowing it to dry, and sanding for a seamless blend. Wood filler is essential in furniture restoration, home repairs, and cabinetry work, ensuring a polished appearance and structural integrity for various woodworking projects.

How long does it take wood filler to dry?

The time it takes for wood filler to dry varies based on factors like filler type, humidity, temperature, and thickness. Water-based fillers dry faster in a few hours, while solvent-based can take up to 24 hours. Follow the product label and consider environmental conditions for best results.
