Measure coating area
Calculate the actual floor footprint and add cove or vertical surfaces separately if they are coated.
Do not count areas permanently covered or intentionally excluded.
Read the technical data sheet
Coverage depends on product solids, target film build, surface profile, porosity, and application method.
Primer, base coat, broadcast coat, and topcoat should be separate takeoff lines when specified.
Account for coat count
Coverage per coat should not be silently multiplied into a single-kit assumption.
Pot life can also limit how much mixed material can be applied before cure advances.
Round by kit
Required coating area divided by effective coverage per kit gives the theoretical kit count.
Round up because two-component kits normally must preserve the specified mix ratio.
Keep preparation outside the coating quantity
Cleaning, repairs, profiling, moisture testing, and etching can control coating performance but are not square-foot waste factors.
Follow the product data sheet for preparation and environmental limits.
