Saint-Gobain Weber Goes on YouTube

Saint-Gobain Weber is known for its dedication to train people in the specification and application of their innovative and market leading materials. Those in need can access a team of technical advisors that will give them information on the correct use of the diverse product offering, wither over the telephone or on site.

Additionally, they have now created a YouTube channel where they post a diverse range of ‘How To’ videos, specifically designed for specifiers and applicators that are not able to attend a related course at the academy. The videos address some of the most frequently raised technical enquiries received by Weber, such as external wall insulation systems, flooring products, renders, and tile preparation.

Weber’s most recent video approaches the problem of the growth of algae, bacteria, fungus, and mould on external surfaces including render and brickwork, experienced in the UK and Europe. It illustrates how to remove it using the high performance weber CL150. “This is an easy to use water-based masonry wash containing carefully selected biocides to clean and sterilise substrates,” said Rob Speke, Training Academy Manager at Saint-Gobain Weber.

The weber CL150 must be applied undiluted to a dry substrate, saturating the affected area with the use of a brush or sprayer. If the problem is more advanced, agitate the surface with a nylon bristle brush which will speed up the process and improve the results. The algae will be killed in 48 hours and the treated area will need jet washing at low pressure. In case of more severe situations, the process can be repeated.

“Once treated the substrate will be protected for a considerable period although in areas of high algae growth, such as north facing walls with limited sunlight, it is advisable to repeat the process every few years to maintain best aesthetics,” said Rob.

The video can be found here and is one of the 30 currently posted ‘How To’ videos.
