When it comes to exterior building maintenance, our favorite product is StoCoat Lotusan. StoCoat Lotusan is a smooth, above grade exterior wall coating that is used on vertical surfaces including concrete, stucco, masonry and EIFS. What makes this product unique is Lotus-Effect® technology. This coating literally keeps building facades completely clean, which in turn extends your maintenance window. Power washing of your building facade will be virtually eliminated once StoCoat Lotusan is applied.
