Concrete Block Construction
Render Systems for Concrete Block Construction
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 with warranty for all concrete block construction, to compliment, protect and enhance this building element.

StoArmat Miral Render System
A BRANZ appraised high performance system to provide exceptional crack resistance and weather protection. The application includes a basecoat 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 Sto Registered Licensed Building Practitioner 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.

Stolit: Coloured Finishing Renders
Stolit organic finishing renders are manufactured in Germany incorporating the latest technology; certified globally and successfully applied to rendered substrates in every climatic zone for over 50 years.
The Stolit range provides the perfect combination of properties: durable, strong, hard-wearing, impact-resistant, malleable, weather-resistant, colour-stable and highly resistant to microorganisms. In addition, its vapour permeability allows your building to breathe while still repelling water.
Coloured Self-Gauging Float Finish Renders:
Stolit K 1.0mm
Stolit K 1.5mm
Stolit K 2.0mm
Stolit K 3.0mm
Coloured Fine Float, Sponge, or Light Adobe Finish Renders:
Stolit MP Natural
The StoColor finish, a serviceable coating embodying intelligent technology for a range of surface functions to compliment the architectural structure and design. The StoColor System, with 800 shades or matched to any colour using the Sto Spectrometer, provides a clear framework and systematic approach to colour based on integrated layers, combining texture and colour for aesthetic appeal.
