Waterproofing Fibre Flex Flash Harry is listed as an auto-part option. Confirm fitment, part number and compatibility before purchase, especially where vehicle-specific matching is required.
An easy-to-use non-toxic compound for waterproofing parapets, flat roofs, roof tiles, walls, gutters, water features and fish ponds.
Fibre Flex is an ideal compound for repairing old acrylic and membrane systems that have over time begun to leak.
Fibre flex has a built-in membrane so an additional membrane is generally not required (except for areas susceptible to significant movement).
In areas of long-term ponding (ponds and water features) or on impervious concrete Fibre Flex should be used in conjunction with Hypercrete primer.
In permanent ponding applications seven rain-free days curing time is needed. Drying time depends on ambient temperature and humidity.
On non-ponding porous surfaces a 50% product and water dilution or a bonding liquid, is recommended as a priming coat.
Do not use to overcoat bitumen waterproofing systems.
Ensure compatibility when applying a waterproofing compound over existing unknown products.
Not recommended where exposure to negative water pressure is present.
Not recommended for swimming pool or fibre glass applications.
Easy clean up with water.
