Flash Harry Fibre Flex 1Ltr/5Ltr (Various Colours)

Introducing Fibre Flex, the easy-to-use waterproofing compound that's perfect for all your DIY needs. This non-toxic compound is suitable for waterproofing parapets, flat roofs, roof tiles, walls, gutters, water features, and even fish ponds! With Fibre Flex, you can repair old acrylic and membrane systems that have started to leak, without the need for an additional membrane.

Fibre Flex has a built-in membrane, making it an ideal choice for most areas. However, for areas that are susceptible to significant movement, you'll need to use it in conjunction with Hypercrete primer. In permanent ponding applications, it'll need seven rain-free days for curing, and drying time depends on the ambient temperature and humidity.

If you're working on non-ponding porous surfaces, we recommend using a 50% product and water dilution or a bonding liquid as a priming coat. Please note that Fibre Flex is not suitable for overcoating bitumen waterproofing systems or areas exposed to negative water pressure.

While Fibre Flex is available in eight vibrant colours, it's not recommended for swimming pool or fiberglass applications. Cleanup is easy with just water. Get your hands on Fibre Flex today and waterproof your project with ease!
