Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why does line width affect how much paint I need?
Paint quantity is based on the actual painted area, not just line length — a wider line covers more square footage per linear foot or meter, so it uses proportionally more paint at the same coverage rate.
Does paint coverage rate vary much between products?
Yes — coverage rate depends on the paint formulation and the floor surface's porosity, so confirm the rated coverage from your specific product's technical data sheet rather than assuming a generic value.
Does this account for multiple coats?
No — this calculates the paint needed for one coat over the total line area. If your job specifies two coats for better contrast or durability, multiply the result by the number of coats.
