CEMIX RUBBERGUARD CORNER 270 EXTERNAL ensures the most critical areas are protected so the waterproofing application is successful, surviving the test of time. Waterproofing Corners take away the guess work at the most volatile areas, ensuring a quality watertight seal that accommodates movement in a variety of different waterproofing applications. These corners are made from a unique grade of rubber, providing an elastic “flexible zone” that follows the line of the wall/floor junction, forming a rupture resistant seal at corner intersections.
TYPICAL APPLICATION & USES
Ensure the surface is clean, free of dust, loose foreign matter and debris. Surfaces must be free of oil, wax or grease residues. Wiping over with alcohol based cleaner is recommended so optimum adhesion can be achieved. If applying over dusty concrete, masonry surfaces, prime first with Cemix primer to stabilise surface.
Over primed surface (CEMIX TILE BOND LATEX) apply a thick coating of the waterproofing membrane CEMIX RUBBERGUARD. With a suitable flat blade knife, fit the corner ensuring no large pockets of membrane or the inclusion of air pockets exist behind the bandage. Apply CEMIX RUBBERGUARD on top of the corner so that it is fully embedded into the first layer. Horizontal tapes (wall and floor joints) should overlap on to the corner by 80mm. Vertical tapes should overlap on to the corner by 40mm.
Application Temp – 5 – 30ºC
The data shown above reflects typical results based on laboratory testing under controlled conditions. Reasonable variations may occur on site.
CEMIX RUBBERGUARD CORNER 270 EXTERNAL needs to be stored in a cool dry place.
