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 the best filler! Used on very badly cracked plasterboard in corners of a room running floor to ceiling & along the flat area of plasterboard. It filled all areas easily & is invisible once lighting sanded & painted. Wouldn't use anything else for this type of fix!

this product is probably one of the best fillers on the market, super flexible

None of the cracks I've ever filled with Fill-Flex have ever come back so I can attest to the product. Rake out crack, brush dust out, fill with this no higher than surface level because it doesn't sand, fine filler over the top, sand, paint. You don't need Zinser guardz, mesh tape, feathering out meters of mud or anything over the top like I see people do for fine cracks. The only thing that lets it down is the weak plastic tub that cracks under almost no pressure, think I would get the tube instead next time.

This stuff dries rubbery, and isn't really hard enough for sanding. I used it for general filling of holes and cracks, and found that it doesn't sand very well, especially at the edges. It will peel like a skin if applied thinly and the edges won't blend flat with the wall. Probably good for corner cracks where there's movement, but I'm wondering what else this is designed for as it's so difficult to get a flat finish with it.

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

Very good filler, easy to work with, fill the gap to a depth ,which allows you to finish of with a normal filler, this allows you to sand to a smooth finish.

I bought this as seen that professional painters recommend it. It's not as easy to use when filling. It takes ages to go off. But the biggest problem, when you sand it it just starts to peel off. You can actually just pull it off like skin. Terrible. Don't know what the hype is with this stuff. It delayed my job. Had to get it all off and use my tried & trusted pollycell plaster repair. This whole new tub after causing me just hassle is in the bin. If anyone has advice for others on how to go about sanding this chewing gum please share to help others. I won't be buying it again

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.
