Rated 5 out of 5 by Excellent, but hardens quickly I've used this to repair some windows and window frames which had been affected by rotting timber. The wood filler works very well, sticks well, can be smoothed, chiselled and then sanded + painted over. It's not difficult to mix with the hardener. It's very hard and strong once set. The only thing to note is that it hardens pretty quickly, so you need to work fast and not mix too much filler in one go. 12 Oct 2016
Rated 5 out of 5 by Good stuff I've been using this on wood and also to fill holes ,cracks and dents in plasterwork. Sand-able in minutes but it does have a downside that means you don't have long to apply it once mixed (I'd guess at 2 minutes max). All in all its fine for the job. 16 Aug 2016
Rated 1 out of 5 by Poor excuse for a wood filler I have used this today I cannot say how disappointed I am! This product would be better used as a filler on car body repairs because that's what it is plastic padding rebranded and you get the plastic padding smell as well! Off the filling knife after mixing it goes hard very quickly so cleaning knife after use is poor. From trying to fill a small gap in corner it would not adhere like normal filler. I then had to hush filling as it very quickly pulled on the knife. Rubbish. 6 Aug 2016
Rated 5 out of 5 by Best filler out there This two part filler is great,iv tried most others but iv found ronseal to be far superior. Iv never had any issues after a job,even when using externally for timber repairs. 12 May 2016

Thanks for your question. The High Performance Wood Filler is supplied with a sachet of catalyst (hardener). If you're treating wood effected by wet rot then it is often wise to treat any softened wood with Ronseal Wet Rot Wood Hardener (63540) prior to filling which is sold as a separate item. The High Performance Wood Filler is available in White & Natural..
