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! ### ⭐⭐⭐⭐ A must for small cracks, bad tub *by Ð***Ô on 25 February 2026* 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. ## Frequently Bought Together - Toupret Fill-Flex 1kg - 310ml Toupret Fill-Flex Flexible Filler for Gaps and Cracks Fibacryl - Zinsser Peel Stop Clear Binding Primer 1 Litre ZINPSP1L --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/357441255-fill-flex-flexible-and-crack-resistant-interior-filler-for-tough](https://www.desertcart.tn/products/357441255-fill-flex-flexible-and-crack-resistant-interior-filler-for-tough) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-29*
