Apply Galv-Etch by pouring or spraying it on roof tiles with a non-metal spraygun.

Leave on for approximately 10 – 15 min

Rinse with clean water & brush/broom

High pressure spray cleaner can also be used after Galv-Etch application.

If moss and fungus growth is very dense, rather use a high pressure spray clean before Galv-Etch is applied, so that Galv-Etch can reach and kill the imbedded spores more effectively. This will prevent regrowth of moss and fungus from the same spores.
