## Questions & Answers

**Q: What is the difference between this and wood epoxy?**
A: It is a two pack wood filler rather than an epoxy.  It is ideal for filling gaps or making up areas where you have needed to cut out rot back to clean wood

**Q: Can this fix wood enough to not crack when its placed under heavy strain? I used a different bed filler and it came off after a single use**
A: It depends how much filler and how deep it is applied. The timber to be filled should be 'completely' dust free prior to filling. Don't put the filler in too thickly. Make a number of applications. When the filler is freshly mixed it is moister and adheres to the timber better. If it starts to get a bit stiff it is better to throw what is left away rather than try to use it. It is better to mix up several smaller batches.
Best Regards,

Rex

**Q: do I use primer on wood filler orunder coat**
A: Whatever you would use normally. Just treat the filler as wood.

**Q: would this work better than just using JB Weld to build up chipped off corners on a particle board speaker enclosure (i.e. not rot etc.)?**
A: I have no experience of JB Weld so can't comment on the comparison. The Ronseal should work but sanding off to precise corners (once fully dry) will be tedious. And you'll clearly need to paint / spray over afterwards.

### ⭐⭐⭐⭐ Plastic Padding For Wood, With Yellow Colouring
*by P***S on 24 August 2015*

I got this to firm up a couple of rotten areas on our deck, after having already used Ronseal's wet rot treatment. As soon as I opened up the tub I recognised the smell and texture of the stuff: it's exactly like PlasticPadding "Chemical Metal ", save for the colour. And that explains why some people have been really happy with it, and others much less so. From a structural point of view, this stuff is brilliant: it sets rock hard very quickly, dramatically increasing the strength of the damaged wood, and I have no doubt that the repair will last for years. From an aesthetic point of view however, it could be a big disappointment. How the final repair looks comes down to two things: your skill in applying the stuff, and the colour, which is quite a warm yellow. In my case, I did a fair job of filling the gaps in the remaining sound wood (which isn't easy because the filler is very sticky - sticks to your fingers and whatever tool you use), grooved it to match the existing decking just before it set, and sanded it quite well afterwards. The colour however sticks out like a sore thumb. If you're going to be painting/staining it after filling then obviously the filler's natural colour won't matter, but otherwise you can pretty much guarantee that it's not going to match any exterior wood that has been exposed to the elements for a while. I'm just hoping that a bit of weathering will eventually make my repair less noticeable, but at least I'm confident that I've stopped the rot and that the wood is going to last for some years to come.
