Cromar Pro GRP Roofing Kit, a handy kit containing everything required for a 13 sqm roof. Individual components are available to purchase separately.
What is PRO GRP?
GRP stands for Glass Reinforced Polyester and is also known as Glass-Fibre.
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.
Cromar have developed this technology further to produce the perfect all weather protection for any flat roof. PRO GRP can be applied in small domestic situations right through to large industrial environments.
