SurfaceTally creates free, independent tools that make decorative wall and renovation material estimates easier to inspect. Our calculators show you the numbers that matter: measured surface, coating layers, product consumption, waste allowance, available package size and estimated purchasing costs.
What makes our tools useful
Instead of claiming that all microcement, limewash or plaster products share a standard coverage rate, we let you enter the specifications of the product you have actually chosen. This keeps the calculation transparent and makes it easier to compare supplier options.
Our editorial approach
The tools use plain unit conversions, arithmetic formulas and whole-container rounding. We document those formulas on every calculator page. Starting values are illustrative examples, not tested product recommendations, confirmed quotations or market averages. Read our editorial and corrections policy for how we describe their limitations.
Scope of the website
We do not inspect your project, guarantee supplier yields, design waterproofing, issue contractor quotes or replace manufacturer instructions. For significant construction decisions, confirm specifications with the product maker and seek suitably qualified advice.
