Cement Sheet Construction
Render Systems for Cement Sheet Construction
StoArmat Render Systems provide the perfect reinforcing render to ensure
maximum system reliability for fibre cement sheet construction.
StoArmat, an organic, cement-free and breathable, high-impact render, with a crack resistance six times higher than that of standard cementbased plasters, ensures maximum system reliability for your building facade. Finished in a choice of different Stolit coloured finishing renders and StoColor for a complete weather tight solution.
At Sto, we aim to offer our customers maximum quality and protection; that is why we continually optimise our systems, utilising the latest building technology providing an innovative edge. Take a look at a facade solution that works as promised, demonstrably better.

StoArmat Render System
StoArmat is a BRANZ appraised exterior render system that provides the optimal protection and durability for Cement Sheet construction. Before the system can be applied the surface is sealed and all joints are then flushed using StoArmat render embedded with Sto Jointing mesh for reinforcement. StoArmat render and glass fibre mesh is then applied over the full substrate, providing engineered reinforcement to reliably dissipate tensile, seismic and shear stress. Finished with perfectly interlocking components: Stolit fibre-reinforced coloured finishing render plus StoColor; creating a 4mm weather tight reinforcement system for reliability and protection that surpasses the facade durability requirements.
Installations are carried out by a Sto Registered Licensed Building Practitioner with the added protection of a StoArmat 15 Year Warranty and StoService Assurance, guaranteeing building code compliant materials are used and application meets building code standards, including a service plan for long-term security.
