Estimator
Using this GRflex materials estimator will tell you how much product you need to purchase for the size of your project.
The first thing we need to determine: Do you need a primer?
GRflex can be applied to the majority of roofing substrates without the need for primer. These substrates include:
OSB (Timber Decking), Felt, Asphalt, Metal, GRP, Liquid Coatings
For these substrates look at Estimator 1 (no primer).
GRflex will need to be used in conjunction with our GRflex Primer if being applied on the following substrates:
Concrete, Single Ply, Asbestos
For these substrates look at Estimator 2 (with primer).
