Preparing and applying the primer
Remove dust and loose material from the surface. Apply the stirred primer with a brush or roller. The substrate may be dry or slightly damp, but it must be firm and free of standing water. Use only outdoors, with good ventilation. Allow the primer to dry before laying the membrane. The manufacturer gives a drying time of about 30 minutes on concrete and about 1 hour on bituminous roofing felt. Conditions on site can change these times.
The manufacturer also specifies this product for priming concrete bridge decks and for protecting buried timber and metal. For a damp-proof coating, apply four coats to a primed surface, letting each coat dry fully. The finished dry coating should be at least 1 mm thick.
