Flash Harry Fibre-Flex Waterproofing 5L

• 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
