SikaRoof® Liquid Membrane is a polyurethane-based liquid waterproofing system for flat and pitched roofs. This fast-curing option is perfect for new projects, extensions or the refurbishment of a leaky roof.
With a two-coat application to most common substrates, SikaRoof® Liquid Membrane can be used in a variety of weather conditions and is rain-resistant after just 10 minutes.
This versatile roof repair product can be used on concrete, mortar, brick, stone, fibre cement, roof tiles, metals, wood and tiles. It can also be used on roofing felt, asphalt and bituminous coatings – but full reinforcement is required for these surfaces as they may soften after application.

• Versatile – suitable for use with new and old roofs
• Fast curing – rain-resistant after just 10 minutes
• Moisture curing technology – no catalyst required
• Ready to use – easy to apply with brush or roller
• Easily recoated – save time with no stripping required
• Vapour permeable – allows substrate to breathe
• Elastic – retains flexibility even at low temperatures
