Choosing the coating thickness
For damp proofing, the manufacturer specifies a 1 mm dry film and about 1.5 kg/m². For standing water or accumulated rainwater, use a 3 mm dry film at about 4.5 kg/m². For water under pressure, the figures are 4 mm and about 6 kg/m².
Apply with a trowel or suitable spray equipment to a sound, clean, primed surface. The substrate may be dry or slightly damp. A damp surface extends the curing time. Protect the fresh coating from rain.
The coating can also be used beneath a balcony screed. It is safe in contact with expanded polystyrene and remains flexible at low temperatures. It bridges cracks; sealing tapes and collars can be embedded around joints and penetrations.
