1) Works well, applied to moss on sidewalk.2) A real bugger to open.3) After carefully following instructions failedI finally ended up using my "AMAZON Hori Hori knife"to pry the lid off!

Use this once a year, to make your roof problem free...my roof is 20 yrs old and I religiously apply moss out once a year in the spring and my roof still looks new...roofers have inspected my roof and guessed at 5 years old maybe 10....wrong...It won't stain or damage your shingles and moss will not grow on your roof, keeping it leak free...

This worked amazing on the moss and staining I had on my garage roof. You would need more than one to cover a large space. This container only covered about a quarter of my roof space.
