Mix Ratio is 4 parts water to 1 part Masonry Cleaner (20% mix rate)
Coverage is 100 to 200 sqft of solution depending ion the porosity of the surface
Instruction:
1) Moisten the surface, wet it down but don't flood the surface
2) Apply the diluted solution, spray top down on vertical surfaces
3) Reapplication is often required where mortar has been splattered about.
4) After a dwell period scraping the larger splatter will speed up the process
Note: Reapplication is performed with rinsing in between
Watch for foaming as the foaming diminishes the work is completed.
5) When satisfied with the cleaning rinse the surface with water.
Know your surface, sandstone, limestone and other softer surfaces should be rinsed at a very low pressures. Garden Hose or about 60 psi
For more robust surfaces use a large sized orifice fan tip to rinse and generate a pressure below 800psi with a high flow on to rinse the more robust Brick and stone surfaces with your wand.
