Concrete Panel Construction
Render Systems for Concrete Panel Construction
The cement-free StoArmat Render System has been developed for maximum system longevity, reliability and weather resistance. It is fracture-resistant, impact resistant and engineered to provide optimal protection and finish for Concrete Panel (Precast and In-Situ) construction, to compliment, protect and enhance this building element.
Our StoArmat Render Systems can be finished in a wide variety of different Stolit coloured finishing renders, ensuring maximum longevity with an individual finish for all Concrete Panel construction. Additionally, the system can be painted with one of our High-IQ paints to provide thermal efficiency as well as style.
StoArmat Render System
A BRANZ Appraised high-performance render system providing exceptional crack resistance and weather protection. Application includes a water-based primer to prepare the substrate, followed by mineral-basecoat render to straighten any irregularities, with uPVC flashings to lock into junctions and joinery forming a neat weathertight seal. Application is followed by StoArmat reinforcement render with glass fibre mesh, providing engineered reinforcement to reliably dissipate tensile, seismic and shear stress. Finished in a choice of different Stolit coloured finishing renders and StoColor.
Installations are carried out by a Sto Registered Applicator with the added protection of a StoArmat Warranty with StoService Assurance, guaranteeing building code compliant materials are used and application meets building code standards, including a service plan for long-term security.

Precast or In-Situ
Primer: Sto Putzgrund
Water based primer in a pail, containing an organic binder and good adhesion properties.
Basecoat: StoLevell Novo
Lightweight EPS bead mineral render (plaster) with good build properties, water retention agents and machine application properties.
Reinforcement Render: StoArmat Render
An organic, weather resistant, cement-free and breathable, high-impact render, with a crack resistance six times higher than that of standard cement-based plasters.
Plus: Sto Glass Fibre Mesh 4/7mm
Easy to install, meets the highest requirements for crack, stress and alkalinity resistance.
Finishing Render: Stolit Renders
Organically bound, highly weather resistant, strong, hard-wearing, impact-resistant, pre-coloured finishing renders. (No cement)
Stolit K Range
Stolit MP & MP Natural
StoColor coating based on IQ Net Technology for functional facades.
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.
