Start from a common project

Use these examples if you already know the job but not the calculator.

How the estimate flows

Measure first, change defaults only when the project needs it, then round up the order.

Measure Start with room size, area, or slab footprint.
Adjust defaults if needed Change coverage, depth, or waste only when the project calls for it.
Round up the order Use the main buy quantity before you order.
