Roll out bubbles and creases. Provide at least 50mm edge overlaps and 100mm border overlaps, as specified in the reference. Follow with two further coats at approximately 0.5 kg\/m² each, allowing each preceding coat to dry completely.\u003c\/li\u003e\n\u003cli\u003eAllow at least 48 hours of curing before overlaying with cementitious screed, subject to actual conditions and the current Product Data Sheet.\u003c\/li\u003e\n\u003cli\u003eClean tools and application equipment with water immediately after use.
