Exterior Plaster Repair Systems
Description

The StoArmat Refurbishment Render System is a well-engineered solution designed to restore and protect ageing masonry and rendered façades. The system incorporates StoFlexyl Filler and Sto Jointing Mesh with high crack-prevention properties, providing reinforcement and flexibility over joints and existing cracks. Once prepared, a full StoArmat meshed reinforcement render is applied, delivering added strength, durability, and long-term performance.

The system is finished with a Stolit finishing render and StoColor façade paint for a durable, low-maintenance exterior finish. Installations are carried out by a registered Sto Contractor and supported by the added protection of the Sto 15-Year Refurbishment Warranty and StoService Assurance plan.

Where renovation benefits are needed, but design constraints or budget considerations are a factor, a StoColor Refurbishment Coating System can also provide an ideal solution for refurbishing masonry and rendered façades.
