SURFACE PREPARATION

Concrete surfaces should be smooth, flat steel processing equipment bay, there is no dirt or other objects that may affect may affect the adhesion of the membrane. Use cement mortar sand to handle the serial position of the wall and the floor is flat. Waterproof surface must be kept clean during construction.

PAINT

Scanning thin primer and paint evenly by brush or roller. The construction area of ​​the primer by the die area of construction waterproofing layers can during the day. Can be applied membrane from 2 - 3 hours after the primer in the weather conditions and normal concrete.

PREVENTION

KM membrane not affect human health.
