I got a bottle of Vitax summer shade greehouse shading for my greenhouse. I followed the directions, 1 part fluid to 8 parts water, however after painting it on, and then spraying (both suggested by the bottle). Its been a few hours, the glass has dried and nothing seems shaded, glass just looks kind of dirty at best. Thinking a stronger mix is needed? Anyone else have issues with this stuff?
