10 Best Wood Fillers 2025 in the UK

The Everbuild Multipurpose Wood Filler is a versatile product suitable for a range of DIY tasks, both indoor and outdoor. It comes ready-mixed, which makes it easy to use straight from the tub without needing additional preparation. This filler is ideal for addressing nail holes, cracks, gaps, and minor imperfections in wood surfaces.

The fast curing time is a significant advantage, with the filler being touch-dry in 15 minutes and sandable in 30 minutes. It can be painted over in as little as 2 hours, making it great for quick projects. The fact that it is solvent-free and low-odor due to its water-based formula is another plus, making it safer and more pleasant to work with indoors. The product is also waterproof once dry, adding to its durability for exterior applications. Available in multiple colors, this filler provides options to match various wood tones, enhancing its versatility.

However, some users might find that its adhesion and performance can vary depending on the wood type and conditions. Additionally, while it claims to be shrink-resistant, minor shrinkage might still occur, particularly in deeper fills. The light stainable option offers flexibility but might not blend perfectly with all wood finishes. Given its ease of use and quick-setting properties, this wood filler is particularly suited for DIY enthusiasts and homeowners looking for a reliable solution for both small and medium wood repair jobs.

The Ronseal High Performance Wood Filler in White is a versatile option for addressing wood damage. It's a chemically bonded filler, which makes it notably durable and resistant to shrinking and cracking. This filler is capable of handling repairs to any depth, and it's robust enough to be drilled, screwed, or planed once dried. It's particularly effective for rebuilding rotten wood and curing wet rot, potentially preventing future occurrences.

In terms of use, the product is suitable for both interior and exterior applications, making it a versatile choice for various projects like window frames, sills, doors, and door frames. The white color may not match all wood types, but it is paintable, allowing for color adjustments post-application.

One of the product's strengths is that it can be used to fill deep gaps without the worry of shrinkage or cracking, which is a common issue with some fillers. However, as a chemically bonded product, users should be mindful of the curing process, which involves mixing a catalyst and might be slightly more involved than using pre-mixed alternatives.

With a high customer satisfaction rating, it’s clear that many find this product easy to use and effective, but some novice DIYers might need to take care with the preparation and application process to avoid mishaps. It comes in a convenient 550g tub with a re-sealable lid, making it easy to store and reuse. For those in mainland UK, delivery options are available, though restrictions may apply for certain addresses.
