How to coat over...
Zego, Eco Block, Formcraft, Thermocell
These are concrete filled polystyrene blocks and are treated the same as the polystyrene cladding. We recommend polymer modified render which is trowelled on 4-6mms thick with a fibreglass mess floated into the surface of the render.
To avoid the possibility of cracking we recommend an additional 1mm flexible texture coating and a final membrane paint on top. This gives the most flexible and durable finish.
