Choosing the coating thickness
The required dry film is 2 mm for ground moisture, 3 mm for standing or accumulated rainwater, and 4 mm for water under pressure. Approximate consumption is 2.4, 3.6 and 4.8 L/m² respectively. For bonding EPS or XPS boards, allow 1–1.5 L/m².
Mix before use. Apply with a trowel or suitable spray equipment to the primed substrate in at least two passes, allowing each layer to dry. When spraying, limit each pass to 3 mm. The manufacturer specifies backfilling after three days and no later than three months after application.
