Sikalastic is Sika's liquid-applied membrane range for roofs — a coating system built up in multiple coats to form a seamless, fully bonded waterproofing layer over concrete or metal roofing, without the joints and laps of a sheet membrane.

Replaces sheet membrane joints with a continuous, fully bonded coating, applied over a correctly prepared and primed roof surface.
