Ronseal High performance White Ready mixed Wood Filler 550g

Great stuff. Does what it says on the tin. Quick setting, sandable, takes paint well and lasts for years.

This has become my go-to wood filler, and in addition to wood, I've used it for filling small holes in plaster, plastic, and metal. The only thing is, you have to work quickly & only mix small amounts as it starts to go off quickly, probably within a couple of minutes. You also have to factor-in the mixing time. I've found that it's not easy to get a smooth finish just with the filler knife, so it usually needs sanding after it's set. However, once sanded it's very smooth & produces a ferfect finish which can be primed & painted, or varnished etc. I'm always tempted to add too much hardener, but doing so reduces the working time considerably, so it's better to add less rather than more.

Tried using this yesterday
Made up a very small amount as per instructions
It started drying in like 2 mins making it unworkable. Tried again changing the amount of hardener I put in. Same resultsx2

It seems to be almost impossible to get the quantity of hardener correct. First batch was hardening while I was still trying to use it (less than 5 mins after mixing) second batch has not hardened after 24 hours.

I had a lot of filling to do so bought the large tin only to find that it was literally only half full of product. Very misleading and extremely dissapointing. Will not be buying again.
