Toupret Fill‑Flex - Flexible & Crack‑Resistant Interior Filler for Tough Surfaces - Elastic Compound for Cracks, Movements & Control Joints - Easy Sand, Paintable - 1 kg

This is a good quality flexible filler which is easy to use.

This really is my favourite filler (along with their fine filler)

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.

Did the job and filled the crack before the top coat filler was applied. Hopefully it does not come back! Time will tell.

Didnt stop the ceiling crack, I gouged out the plaster, put scrim tape in, then the toupret. This dried as hard as nails and was extremely difficult to sand afterwards as i overfilled it. The crack still shows at certain times of the year according to the houses internal temperature. So it did not cure the crack after spending many hours prepping and filling per the instructions.

Our Victorian flat has hairline cracks everywhere. I've had to get quite handy at filling. I spent a long time filling some cracks with regular filler and was pretty annoyed when they opened back up 6 months later. I opened up the cracks again, and refilled with this stuff. The repair has held for a year. I'm keeping my fingers crossed and will only be using this for similar cracks in the future. As per other reviews, this is harder to work with than other filler. It is similar to caulk to apply. Unlike other reviews, I found that it actually sands well if you leave it a week to go off and cure and then come back to it with an orbital or rotary sander. You can then paint over for an invisible repair. Great stuff.

Not difficult as some reviews lead you to believe

Perfect for larger patches / patches that wont go away. The only downside is that it is difficult / nigh on impossible to rub down, I was warned and still made the mistake. Much better to build up not daub it on

Très, très cher et a mis du temps à arriver. Les dates de livraison promises n'ont pas été respectées
