We were approached by the contractor who wanted to use Advantage® for Asbestos Roofs due to their experience of the system and ease of use (only one coat needed).
We conducted a site survey with the contractor and sample patches were applied to compare against other systems.
A site specific specification was written which included the pre-sealing of the sheets with a water based product, keeping the eco-credentials of no VOCs and environmentally harmful products to a minimum.
The use of primer also improves the cosmetic appearance by reducing absorption of the top-coat into porous areas.
