Exterior Render Repair Systems


Repairs for Cracked and Leaky Substrates



Overview

Where building facades have been impaired by environmental impact, seismic movement or structural stress a suitable remedial system must be implemented.

 

With the limitations of cement based render products Sto has developed the malleable high impact weatherproof StoArmat Remedial Render System to repair, refurbish and renew existing render surfaces. Optimised over 50 years, six-times more flexible than standard cement-based products and manufactured in Germany to guarantee quality and application consistency, the StoArmat Remedial Render System with it’s range of finishing renders and coatings exceeds expectations.

 

Where the benefits of renovation is required, but cost is a major issue for the project, a StoColor Coating System for refurbishing masonry and rendered facades, may be ideal.
