It sprayed everywhere on everything and the over spray blew nicely into my face. Have used a lot of rattle can sprays and this is nothing what I expected. It had good coverage and the mildew grew right on top of it just several weeks after applying.

Happy with the product

It kept clumping up coming out of the spray head, had to wipe it often. Leaves glops in the surface you're painting. On the good side it dries fast and doesn't smell too bad. Just covered the area with two applications. Plan accordingly.
