Case Studies | Felt Roof Repair with Hyperdesmo A-810

This old felt roof was in need of some refurbishment. The contractor decided the best course of action was to overboard it with OSB3 and then seal it with the Alchimica A-810 liquid system. It can be applied without a primer in just one coat on OSB3!


You can see the results below.
