Acid Wash Volume Calculator

Acid and rinse in proportion. The rinse volume is the part that protects the stone: acid left in the pores etches as it dries, so a rinse that is short of the figure here is the usual cause of a floor that looks worse after the wash.

The acid and rinse volumes follow the coverage rates and the rinse pass count entered, and they assume the acid is diluted exactly as its label directs. This tool does not test whether the stone tolerates acid: calcium-based stone can be etched by it, so a discreet test area comes before the first pass. This is a planning figure for the values entered, not a measured result. Coverage rates, product yields and application rates are properties of a specific product, applicator and substrate, and the label or data sheet for the product you are using always takes precedence over the default here. The EPA-registered label governs. Using a registered antimicrobial inconsistently with its labeling is unlawful under 7 U.S.C. 136j(a)(2)(G), and 40 CFR 156.10(i)(2)(ii) requires every label to carry that statement. This tool does arithmetic; it does not approve a dilution, and it does not determine compliance.
