No product or installation guarantee
Results depend on the numbers you enter and mathematical assumptions described on the relevant page. Starting values demonstrate each calculator and may not match any manufacturer. Check current technical data sheets, actual site measurements, local building requirements and installer instructions before purchasing or using materials.
Wet areas and specialist surfaces
Quantity estimates do not establish that a coating assembly is waterproof, code-compliant or fit for its intended substrate. Appropriate design, preparation, product compatibility and professional advice remain the responsibility of the people directing the project.
Price examples
Displayed dollar values are sample inputs, not live prices, supplier recommendations, binding offers or contractor quotations. Actual prices, taxes, freight and labor should be confirmed independently.
Permitted use
You may use these tools for personal or professional planning and download your own calculations. Do not misrepresent example results as tested product data or claim that SurfaceTally has certified a coating system.
Service changes
Features, formulas and content may change as bugs are corrected or tools improve. Keep copies of important project assumptions and confirm them again before use.
