Features high elasticity and moisture resistance. Forms part of external thermal insulation systems when used in combination with MARMOCRYL renders. Can be applied to facade insulation boards with reinforcing fiberglass mesh, serving as the ideal substrate for the subsequent coat of render. Suitable also as an adhesive for bonding themal insulation boards to building facades. ISOMAT AK-THERMO ACRYL is a highly flexible, fiber-reinforced, ready-to-use coating based on synthetic resins. It provides high initial and final bond strength, high elasticity and resistance to moisture. It accelerates and simplifies the application. Certified according to EN 15824 and classified as a V2 W3 render. Aldo certified according to EN 12004 and classified as a D2E adhesive. CE marked.
Substrate
The thermal insulation boards must be applied in a staggered pattern (like brickwork), without continuous vertical joints. Any voids between the boards must be filled with expanded polyurethane foam. The entire surface must be levelled.
Application
Before application, ISOMAT AK-THERMO ACRYL must be stirred well with a low-revolution mixer. The material is applied with a smooth trowel at maximum thickness of 2-3 mm. Then, a reinforcing fiberglass mesh is placed and firmly embedded into the fresh base coat layer with a smooth trowel. Finally, the surface is smoothed out and the excess adhesive is removed. The fiberglass mesh strip should overlap each other by approx. 10 cm.
