Properties and values

Application by brush or spray equipment to internal and external damp substrate surfaces
Approx. 4 kg/m²
In warm or windy conditions, wet the surface with water fog or wet tarpaulin until sufficiently cured, or for at least 2 days. In cool conditions cover with insulated tarpaulin or other insulating material until sufficiently cured, or for at least 2 days. Protect against rain until full cured, in cool, damp or badly ventilated spaces, it may be necessary to allow for a longer curing time. To avoid condensation, extra ventilation will be necessary. Never use dehumidifiers during the curing period or within 28 days of completion of the work
Should be stored in a cool dry place, in original packaging, under cover, clear of the ground and protected from all sources of moisture and frost. Liquid component cannot be used once frozen
