What To Think About Before You Buy Wood Filler in the UK
Choosing the right wood filler means looking past the price tag and focusing on what your timber actually needs. It can be surprisingly tricky! Here are six critical points to help you land on the best product for your specific repair job, ensuring you get it right the first time.
1. The Damage Type
Is it just a tiny nail hole or a massive chunk of dry rot? If you have serious, structural damage or wet rot, you absolutely need a two-part High Performance filler like the Ronseal one we covered. For simple cracks, small chips, or minor blemishes, a standard Ready-Mixed paste is fine. Using the wrong type means the repair won’t last.
2. Interior vs. Exterior Use
Not all fillers handle the rain and sun. Always double-check the label. Many modern fillers work inside and out, but exterior products often need an additional coat of oil-based paint or varnish to properly seal them against the UK weather. This is crucial for durability.
3. Application Depth
If you have a very deep gap (say, over 5mm), most ready-mixed fillers will require you to apply them in thin layers, waiting hours between each coat. That takes forever. If the hole is deep, look for powder fillers or the heavy-duty two-part chemical fillers, as these can usually be applied much thicker in one go.
4. Speed of Repair
Do you need the repair done now? Some fillers, especially the fast-cure options, can be sanded and painted in as little as 30 minutes. Others can take a whole day to fully harden. If time is a factor, check the Full Cure Time before you buy.
5. Sanding and Finish
How much do you hate sanding? Some fillers, like the “One Strike” product, dry so smoothly that little to no sanding is required. Others, particularly hard-setting powder fillers, can be incredibly tough to sand down but give a harder finish. Pick the right balance for your effort level.
6. Paint and Stain Matching
If the repair will be visible and you plan to stain or varnish it, make sure you pick a filler that is explicitly stainable. Standard white or coloured fillers might not absorb the stain properly, leaving an obvious patch. If you are just painting over it, any white filler will generally work fine.
The Final Say on Filler
Choosing the right wood filler truly makes or breaks your repair. We’ve covered everything from those quick, convenient tubes for minor chips to the seriously tough, two-part systems needed for deep, structural rot and damp-affected window sills.
When choosing between them, think about the depth of the damage first. Are you looking for strength that you can drill into, or just a smooth surface for painting? If your wood moves a lot, look for flexibility to prevent future cracking.
Getting the right product means your repairs will last for years, saving you time and effort down the line. It’s totally worth the small bit of extra thought now to ensure a professional, long-lasting fix.
