Our First Encounter with the Product
I've used this dry formula moss killer on my roof and patio, and it worked surprisingly fast. The granules dissolve into a non-staining solution that doesn't damage gutters, which was a relief since I have galvanized ones. I sprinkled it dry in the crevices and let the rain activate it, saving time on rinsing. It's great for hard-to-reach areas and leaves no lingering smell. The 6-pound size covers up to 4,000 square feet, so it's efficient for larger projects.
One thing I appreciated was how versatile it is indeed-use it dry or wet depending on the situation. It's not just for roofs; I applied it to brick and sidewalks too, and it didn't leave any residue. However,I noticed that some surfaces required multiple applications for complete moss removal.The product is easy to handle, but the granules can be messy if not stored properly. it's a solid choice for maintaining clean, moss-free surfaces without compromising safety.
The micro-granule formula is a bit unique, but it's effective when used as directed. It's durable and long-lasting, adding months or even years to the life of my roof and concrete areas.I'd recommend it for those looking for a straightforward,eco-pleasant solution. Still, the package is heavy, which might be a drawback for storage or transport.
