Product was difficult to apply and looks terrible when applying, almost like applying paint instead of stain. The stain looks like “yellow-paint”. Held color pretty well in 14 month exterior exposure testing but some mildew growth was visible.

Had our one year old deck stained by a professional painter. We chose the waterborne superdeck bamboo product. They applied 2 coats and the opacity is far beyond what is shown in the color guided. It looks like paint and after spending over $20,000 on the new deck, I am extremely disappointed in the appearance. Sherwin Williams will never get my business again.
