Description

Hi-Flex Laminating Resin — Flexible Waterproofing for Under-Tile

Hi-Flex Laminating Resin is the elastomeric waterproofing component of the Hi-Flex Plus System. Unlike the rigid All Deck Laminating Resin, Hi-Flex remains permanently flexible after curing, allowing it to bridge substrate cracks and accommodate structural movement without membrane failure — essential for applications where tile or stone will be installed over the waterproof layer.

Key Difference from All Deck Laminating Resin

All Deck Laminating Resin cures rigid (for direct foot traffic). Hi-Flex Laminating Resin cures flexible (for under tile/stone). Do NOT use Hi-Flex where the membrane will be the walking surface — it requires a tile or paver overlay for protection.
