Weber #CleanAndProtect

With prolonged damp weather conditions across the UK and Ireland, building facades of all types are subject to the build up of algae. Those which are near expanses of water or woodland areas are more susceptible to algae and mould growth, as well as north-facing elevations which receive less direct sunlight.

Our #CleanAndProtect products are here to help remove organic deposits and protect renders from further growth to keep them looking fresh.

Protecting render

Whilst monocouche render is low maintenance, like any other building facade it is not immune from the gradual buildup of organic growth and dirty deposits or graffiti. This guide will show you how to protect render to prevent these issues arising.
