Saint-Gobain Weber says it has improved formulation of its weberpral M monocouche render in order to combat algae.
Algae growth on external surfaces is not new but its increase is due to warmer winter climates and prolonged damp weather conditions which are being experienced across large areas of Europe, according to the company. In conditions that do not fall below zero temperatures algae spores continue to grow and can affect many exposed surfaces.
Factory produced to ensure product consistency weberpral M is a cementitious, through-coloured render for one-coat application to suitable brick or block work substrates. Produced from carefully selected raw materials, the render is formulated for pump application which is designed to allow for quick and efficient installation. This aims to shorten programme periods, reducing associated scaffolding and site costs and permit the completion of ground works at an earlier state. It is supplied ready-mixed with only the requirement of clean water to be added on site and is applied in a two pass operation to a thickness of 20-28mm; it is then scraped when green giving a minimum render thickness of 15-25mm.
The company says it is the first manufacturer of monocouche renders to be awarded an A+ rating as defined in the BRE Global 2008 Green Guide to Specification. It is available in a palette of 24 colours.
