What Is LAVA 20 Liquid Roofing?
LAVA 20 is a single-component polyurethane liquid waterproofing membrane designed to form a seamless, bubble-free protective layer across your roof. Unlike traditional felt or multi-layer systems,
Once cured, it creates a highly elastic, UV-stable membrane with excellent mechanical strength. It is also ideal for UK weather conditions, as it can be applied in temperatures down to 0°C, becomes rain-resistant in around 30 minutes, and typically cures in approximately 2 hours at 20°C.
Key performance benefits include:
-
Up to 25-year life expectancy
-
Seamless, defect-free waterproof membrane
-
Excellent resistance to UV, rain, and harsh weather
-
High tensile strength, tear resistance, and abrasion resistance
-
Remains flexible down to -40°C
-
Withstands thermal shock up to 200°C
-
Breathable system that helps prevent trapped moisture
Before applying LAVA 20, surfaces are primed with LAVA Prime 20, ensuring strong adhesion on both porous and non-porous substrates and helping deliver a reliable, long-lasting finish.
Suitable for Almost Any Roof Type
One of the biggest advantages of LAVA 20 liquid roofing is its versatility. It can be used for waterproofing and protection of:
-
Flat and pitched roofs
-
Concrete and timber decks
-
Felt and asphalt membranes
-
Lightweight metal and fibre cement roofing
-
TPO and EPDM membranes
-
Balconies and verandas with light foot traffic
-
Podium decks and planting boxes
For roof details such as flashings, pipes, chimneys, gutters, and wall junctions, LAVA 20 can be combined with LAVA Detail 20, creating a fully reinforced, watertight system across every vulnerable area of your roof.
