The project work featured algae removal, render cleaning and maintenance, near Cirencester, Gloucestershire.

The maintenance of the render system had unfortunately not been carried out since installation of an EWI and acrylic finish render system, 10 years ago.

There was intrusive algae build up on silicone rendered surfaces, which will penetrate the system if not treated. There is a diverse range of algae organisms.

The project consisted of algae treatments followed by render re-coating where algae had penetrated an acrylic top coat.

Elevations with non intrusive algae contamination were also treated and cleaned before a coating of silicone paint. Silicone renders & paints contain greater anti-fungal properties.

If maintained, silicone renders provide unrivalled longevity. A bi-annual maintenance plan will save considerable sums over the life span of a new Render system.
