Concrete Block Construction
Render Systems for Concrete Block Construction
Overview
From the start of civilization solid mass masonry materials have been used to provide a durable means of building. Sto has a traditional background of treating masonry surfaces throughout Europe for over 150 years. Based on this experience in concrete block methodology Sto has developed the StoArmat Render System which is fracture, impact resistant and engineered to provide optimal protection and finish for all concrete block construction, to compliment, protect and enhance this building element.

StoArmat Miral Render System
A high performance system to provide exceptional crack resistance and weather protection. The application includes a basecoat with Levell Novo render to straighten any irregularities. Followed by StoArmat render and glass fibre mesh, 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 registered Sto Contractor with the added protection of a StoArmat 15 or 20 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.
