All exposed timber, including vertical cladding, is eligible for algae/black mould contamination.
After an initial period of exposure, the natural cellulose binders degrade and wash away. The surface becomes grey when bare cellulose needles are exposed. This surface becomes a natural habitat for algae and moulds, generally deleterious to the material. Wood stains obscure wood veins as new coats are added and are as a result only partly successful at maintaining the intended appearance of timber surfaces. Periodical use of AlgoClear® Pro Softwash is perfect for Deck Cleaning and will preserve the timber as well as its appearance.
