Ihave a roofing contractor for a flat roof. He suggests using Cromer poll for about 30 sq metres. I don’t want to go for a full re roofing. What is the life expectancy of Cromer Poll and how much of the substance is required for the size of roof given. What is the exact name of the substance as I see you have various products. ?What colour is best for a longer life?
Cromar Cromapol Acrylic Roof Coating - Fibre Free has a coverage rate of 1 to 2kg per m² on average.
For 30m² you would require approximately 60kg.
Please note this is designed as a repair product and not have a listed life expectancy.
