SikaRoof Liquid Membrane FAQs
How do I apply SikaRoof Liquid Membrane?
Use a soft-bristle brush or solvent-resistant roller. Apply two coats at roughly 1mm each, letting the first coat dry before the second.
What roof surfaces can I use SikaRoof Liquid Membrane on?
Works on mortar, brick, stone, metal, wood, tiles, roofing felt and asphalt (soft/bituminous surfaces may need reinforcement).
How durable and flexible is SikaRoof Liquid Membrane?
SikaRoof Liquid Membrane forms a fully bonded, seamless waterproof layer that moves with the roof rather than cracking. It has high elasticity, meaning it can stretch and recover with building movement or temperature changes without losing adhesion. Once cured, it is UV and weather-resistant, providing long-term protection against rain, sunlight, and temperature extremes.
What prep do I need before applying SikaRoof Liquid Membrane?
Make sure the surface is sound, clean, dry, and free of dust or loose material. Fix cracks first. On very porous or uneven areas, apply a primer coat before the main coats.
How quickly does SikaRoof Liquid Membrane become rain-resistant?
It becomes rain-resistant in around 10 minutes after application – handy for changeable UK weather.
Do I need reinforcement?
On simple, solid substrates you may not. For felt, asphalt or soft/irregular areas, use reinforcement fleece such as Sikalastic Fleece-120 at details and stress points.
