Dry time may be longer in cold temperatures. Deep puddles of primer should be avoided as this will lengthen drying time.
Do not apply directly to BITUTHENE® membranes.

Priming should be limited to an area that can be covered with membrane on the same day. Areas that accumulate dust or dirt must be re-primed before membrane is applied.
