Will a Westech fence mildew?
Mildew feeds off of organic materials. Vinyl (PVC) is non-organic and therefore does not support mildew. Mildew that grows on Vinyl is actual feeding off of the organic materials (dirt) that have become embedded in or stuck to the vinyl. Westech fence profiles have a high gloss and smooth, non-porous surface that makes it very difficult for organic materials to attach to, and therefore, for mildew to thrive on. This, combined with the use of non-chalking TiO2 helps to prevent most mildew growth. The surface of vinyl fence that contains chalking TiO2 deteriorates at a much more accelerated level compared to non-chalking TiO2 creating a rougher surface that dirt and therefore mildew can attach itself more easily to. Only under very consistently damp conditions will the possibility of mildew occur. If mildew does appear, a mild solution of bleach and water will easily remove it.
