Need to seal overlaps on pressed cement roofing sheets then seal full sheets. Will also need fungicidal treatment. Please advise which products in which order and if use of re-enforcing is needed for joints. Standard double garage size.


As a minimum we would recommend cleaning the surface, applying Britannia Fungicidal Wash Solution and allowing to act. Wash down and allow to dry and prime with Britannia Durashield FD Primer and allow to dry. Scrim joints using Britannia Reinforcing Scrim in a basecoat of Britannia Durashield. When dry, apply a final coat of Britannia Durashield to entire area.
