Surface Preparation
The surface of the concrete shall be sound, clean and uncontaminated, free from dust, nails or any deleterious matter.
Priming
A coat of ASFABIT must be applied to the concrete surface and must be allowed to dry completely primer to completely cure (2- 6 hours), and apply membrane no later than 24 hrs from priming. Reprime areas if contaminated by dust.
Fixing Membrane
Peel back the release film no more than 30 cm at a time, with adhesive facing primed surface. Press down the membrane against the substrate with a rubber/ wooden starting from center to side edges in order to expel any entrapped air.
For vertical application, installation shall be in approximately 2.5 meters manageable lengths.
Overlaps
Membranes are produced with selvage to facilitate bitumen to bitumen strong lap joint. Side laps shall be 7-10cm, and end laps 15cm min. After removing selvage release film, press down firmly against side and end laps, with the help of a light roller.
Protection against backfill
Membrane should always be protected to avoid damage caused by other trades, backfill material, tools, or earth moving equipment. BETOBOARDI asphalt impregnated protection board shall be applied, spot bonded, to vertical and horizontal surfaces following membrane installation.
Horizontal surfaces can receive protective screeds, or concrete instead of the protection board.
Recommendation
n It is recommended to use protective gloves during installation.
COLBETOMO SSA have no health hazard when used with our standard application recommendations.
