Rated 5 out of 5 by Works a treat. Bought this to fill a few cracks in a wooden door and to tidy up a few wooden window frames. Excellent product. Easy to mix and use. Left to dry for 15mins and carved off the excess with ease. 10 mins later it was rock solid and ready to sand and paint. Just go easy on the hardener to prolong the working time. Not sure if the amount of hardener supplied will be enough to last the can of filler. Time will tell. Overall a great product and screwfix was the cheapest in the whole wide world. Probably...... 23 Oct 2016
Rated 5 out of 5 by Woody filla Best 2 part wood filler I've used, smooth, easy to mix, easy to sand, could do with a bit more hardener I always end up running out . 20 Oct 2016
Rated 5 out of 5 by Great wood filler Easy to mix, goes off in 5mins, sand after 10mins Just be quick & don't mix too much or it'll be off before you can say 'oh blow...!' 9 Sep 2016
Rated 5 out of 5 by Fantastic stuff! Used this when I needed to move a strike plate for a front door lock, drilled out the old screw holes and filled with this as the adjustment was only 1-2 mm and the old holes would have got in the way. This stuff is very smelly, the fumes are horrible so work in a well vented area. Don't go crazy with the hardener, a little really goes a long way. I mixed up half as much as I needed to minimise waste. Working time for me was about 10 minutes. The reaction gives off some heat, so mix in an appropriate container. I used disposable plastic cups and got away with it. Have marked three stars for value just because dosing with the hardener takes some practice and first time users will waste lots of the filler as it goes off so quickly. Would buy again, just wish it was available in a smaller pot, 250ml would have been perfect for my needs. 5 Sep 2016

Thanks for your question. You can stain this filler but please be aware that it is unlikely to take the stain in the same way as the surrounding wood therefore after staining the repair may still be visible.
