ROOF SEAL and membrane should be applied to all cracks, expansion joints and 90° joints. Apply 1 coat of ROOF SEAL liberally to all areas where the membrane will be placed. Dab the membrane into the ROOF SEAL by using the brush. Apply the membrane in sections of 30 - 40cm at a time ensuring that the ROOF SEAL is still wet. Apply 2 coats over the membrane, allowing sufficient drying time between coats.
