WATERPROOFING

CLI TOUGH COAT

PU Based Waterproof Membrane

DESCRIPTION

CLI - TOUGH COAT a waterborne polyurethane based acrylic copolymer formulation, which may be applied by brush, roller or airless spray equipment. It is free from strong odor and toxic fumes and cures to form a tough, matt, elastomeric membrane, which tolerates substrate movement and does not embrittle with age, or prolonged exposure to ultra-violet light.

MINIMUM APPLICATION TEMPERATURES

Throughout the application and curing period, ensure that the substrate and atmospheric conditions remain 502F and 52F above the dew point. Do not allow temporary ponding to remain between coats on any horizontal surfaces or until the final coating has totally cured (up to 7 days at a minimum of 502F). Brush or mop surface water away during this time. Do not allow the applied CLI - Tough Coat to be exposed to freezing temperatures until the final coating has totally cured (up to 7 days at a minimum of 502 F). Premature exposure to above conditions could cause flaking, cracking and/or coating failure.
