Application Information

Instructions for use

Surface Preparation

The surface to be waterproofed 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 before the application of the membrane.

Application

COLBETOMO APP membrane are installed by torch welding. The membranes are laid over the area they are to be fixed overlapping each other by at least 10cm. Lap joints should shed water towards the drains.Without changing the orientation, roll back the membrane. Unroll the membrane once again and heat the underside properly to allow the surface to melt. End laps should be from 12 - 15cm. COLBETOMO APP should be heated from the top to create a thin bead of molten bitumen at the seam. Using a trowel, smoothen the surface to ensure a properly welded joint.

Exposed Roofing Application

COLBETOMO APP mineral membranes which are manufactured with self-protecting layer of natural slates are used for exposed applications, roofing and skirtings. Scrape off 15cm of mineral flakes or press in the slate and expose the bitumen by heating 15cm of the mineral surface sufficiently to make end of roll joints. Next roll will be torched on the exposed bitumen area.

Additional Information

Health & Safety

COLBETOMO APP have no health hazard when used with our standard application recommendations.
