Cromar PRO GRP Roofing Resin is a pre-accelerated, pre-promoted, thixotropic, medium reactive polyester resin designed specifically for Roofing Applications and formulated to give extremely low styrene emission. This product is a key component to the PRO GRP system.

Cromar PRO GRP is a Glass Reinforced Polyester flat roof system designed and engineered for flat roof applications. PRO GRP is a fully integrated all in one system where the components work together on virtually all types of flat roofs and vertical surfaces in any domestic or commercial application to provide the perfect all weather protection.

This system is cold applied on site, giving it a seamless and flexible weatherproof finish that resists water, heat and frost. The resulting surface gives a strong architectural finish that looks very impressive. If maintained properly it will last as long as the building stands.

Coverage:
1.5kg of Resin per m2 (Allows for 10% Wastage)
Therefore:
10kg = 6.67m2
20kg = 13.3m2

Please note the above coverage is based on using standard 450gsm matting. When using ticker 600gsm matting, approximately 33% more resin is required per m2.

FEATURES AND BENEFITS

• Very low styrene emission
• Low viscosity allowing rapid and effective fibre wet-out
• Long pot life combined with rapid cure
• Clear colour
• 25year manufacturer’s warranty when installed by an approved contractor

STORAGE

Resins are stable for six months from date of production when stored in the original containers away from sunlight at no more than 21°C. After extended storage, some drift may occur in gel time. During the hot summer months, no more than two months stability at 30°C should be anticipated.

CLEANING

To clean tools, use acetone in a re-sealable container. It is advisable to use paintbrushes with unpainted handles as the paint will contaminate the resin. Always use disposable latex gloves when handling resins and topcoat, use hand cleaner or wipes to clean off resin or topcoat. NEVER clean hands with acetone.

Please note, it is NOT recommended to install PRO GRP in temperatures below 5°C and above 35°C ambient temperature. Please consult Cromar’s technical department for further information.
