The StoStucco Plaster System incorporates a European lath made from a stainless steel welded wire mesh with an absorbent sheet of perforated chip paper, and fixed over timber battens to form a cavity and allowing for a dry zone between the interior and exterior claddings. The stainless steel lath can be moulded to suit the shape and curvature in any building.
The StoStucco System consists of a Lightweight mineral basecoat which sits around the stainless steel lath, providing a thick solid plaster base. uPVC flashings lock into the joinery providing a neat junction ready for a weathertight sealant. As additional reinforcement, StoArmat plus Stomesh reinforcement plaster is applied over the basecoat. StoArmat is a cement-free, ready-to-use, flexible plaster, providing maximum crack and shock resistance of six times higher then that of cement based products. The Glass fibre mesh is an alkali-resistant reinforcing mesh with total uniform force absorption and it reliably dissipates tensile and shear stress. The façade is finished with interlocking components: Stolit coloured finishing render plus a StoCoating of choice.
Installations are carried out by a Sto Registered Licensed Building Practitioner with the added protection of a 15 or 20 year Sto System Warranty and 5 year renewable Workmanship Warranty plus Maintenance Schedule.
