Seems good. Easy to put on, easy to flatten.

### ⭐⭐⭐⭐ A challenging product, for challenging jobs.
*by S***K on 16 February 2025*

First thing I would say is - smooth, smooth, smooth - as much as you can, before it dries! Used thinly it goes elasticky and peels off, used thickly it dries hard as rock and my orbital sander struggled to make much impact smoothing it off. I wanted to fix a ceiling crack which a painter and decorator had already 'fixed' twice but kept returning. I cut down some wall repair patches (the ones with the stainless steel mesh) and used this filler to fill/adhere the long crack. I had pre-scraped it so I could use a decent amount of product and not apply it too thinly. I usually over-fill as it's pretty easy to sand repairs to a nice level finish, but this is very challenging to sand so take a bit of care over smoothing it before it dries if you can. I also used a bit of this sparingly on a smaller area and on that one it went like chewing gum when sanding so I peeled it off and reached for the normal filler. It seems to be holding on the ceiling repair so I do think this works, for the right job. It's not for the faint hearted - but I needed something that would hold on a long crack in a bathroom that gets steamy. Overpainted with zinsser mould-resistant paint it looks decent - fingers crossed it stays that way.
