## 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.

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐ Sets quickly to give a strong repair
*by A***N on 24 March 2024*

This product works well, even for larger repair jobs on wood. I needed to repair my side gate which had a hole all the way through it, measuring approximately 30cm x 2cm. The filler was easy to mix and apply. I mixed up golf ball sized quantities and filled the hole up gradually after reading other reviews that said the substance set quite fast and this approach worked well. Within 20 minutes or so (on a dry day) the substance was completely hard and ready to sand down. I have just deducted one star for two reasons. 1. When I tried to stain over the product, my Shed and Fence Preserver (which is a good quality brand) just kept running off and wouldn't adhere so I now have no hole in the gate but instead have an odd looking patch! My gate is rustic green so perhaps with hindsight I should I have chosen the dark coloured filler. So you may want to consider this before purchasing. 2. Also, I have about half of the product left and have tried to reseal everything and make it air tight but it was so difficult getting the metal lid/insert off the top of the can when I initially opened it that it dented slightly when I prised it off with a screwdriver. I am therefore not sure if the remaining product will be usable next time I need it . . . time will tell.
