Too grainy and translucent, poor adhesion, doesn’t sand well.
I’d expected this to be a decent product, because other Rustins stuff I’ve tried has been good. Sadly it’s the worst filler I’ve ever used, and it fails on almost every front,
1. It’s made up of large grains so it’s pretty rough when you apply it, it also doesn’t seem to want to stay in place. Tying to smooth it off or bed it in, just lifts it back out,
2. It’s almost translucent and doesn’t have enough pigment. Any shallow areas filled will show the colour underneath, which is really unacceptable.
3. It doesn’t adhere well when dry. Given that you can’t smooth it off when applying, the rough bits tend to snag as soon as you sand it, not matter how gentle you are. It then crumbles and falls apart or dislodges.
Imagine crumbling up a digestive biscuit, adding a bit of water and filling your wood with that. It’s a similar experience with this stuff.
Buy any other wood filler and I reckon you will be better off than buying this.
