StoStucco Render System
Stainless Steel Lath over Cavity Construction
Please note: Due to a current worldwide shortage of StoStucco lath, we are experiencing supply delays. Please contact your local Architectural Manager before specifying the StoStucco Render System.
Stucco, an outstanding solution with a reinforced backing, dates back to pre biblical times using saplings and an application of clay plasters to decorate and protect buildings.
Embracing this concept by using the latest render technology and European components, Sto has released StoStucco, a render system on a rigid stainless steel lath. This compliant system meets the requirements of the New Zealand building code for architects and designers. Following traditional practices the StoStucco System is a guaranteed solution to cover timber framed construction and allows the designer an opportunity to bend the rules when designing residential or commercial construction property.

Manufactured in Europe, the StoStucco lath is made from a stainless steel welded wire mesh with an absorbent sheet of perforated chip paper, fixed over timber battens to form a dry-cavity. The StoStucco lath provides an extremely strong yet flexible base for the render system to interlock with and can be moulded to suit the shape and curvature in any building, creating unlimited design possibilities.
StoStucco Render System
StoStucco is a BRANZ appraised render system based on the traditional New Zealand stucco net system. The StoStucco lath with perforations in the chip paper allow an optimal key of the lightweight mineral basecoat to sit around the stainless steel wires, providing a solid render base. UPVC flashings lock into the junctions and joinery providing a neat junction ready for a weathertight sealant. The cement free StoArmat, combined with a glass fibre mesh provides 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.
