Ronseal High performance Wood filler very easy to use. Excellent to work with if you follow the the instructions. The finished repair was smooth and strong, looked as good as new. Wood (play on words) definitely use again.

Witchcraft Engineer Verified Purchase

Great two part filler for wood. Used to fill holes in doors, door frames, to fill screw head holes and edges of plywood boxing, which now looks as smooth as silk, as if it's a plastered beam!

I also tried it on an oak worktop where the staves had separated but there's too much movement in that section of worktop for it to last so the split appeared again. If the top was solid and not slightly flexing it would be fine.

Rock solid once set. Easily sanded but wear a mask! Once fully painted you'd never know it was there.
Use a pea of hardener to a golf ball of filler, sometimes I got the ratio a touch wrong and it set as I was applying! Mix enough for what you need, or split your job into stages if lots to fill.

Very good, would use again.

Just about worth the money

This is an excellent product, I've just spent two weeks repairing old rotting windows and doors. This stuff is easy to mix and apply and sets really quickly allowing you to sand it down in 10mins. This product ends up stronger than the wood itself. I always keep a couple of tins in van.

Great product for filling

Performed as I would expect a two pack product to. I assume that it's a long term repair but never give 5 stars after such a short time.

Fantastic product,easy to use, after chopping the rot from the door after repairing,it was stronger than before,the resin set strong enough to drill into,and fix a new weatherboard to it without any issues.
This is the best repair filler I have ever used.

Don’t bother with this product.

I had high hopes for this product but not so good it went off in just over minute and then just crumbled so really no use at all.

Always well stocked

It is good stuff. Working time is short but that means you can sand within minutes. The tin is difficult to open with a very deep lid and small gap to get a tool in. That is rubbish. The shelf life isn't forever and the working time will get even shorter the older the product is. I don't think there is anything out there that is much better though.
