Stone, Countertops & Engineered Surfaces worked example

Sealer Coverage at 99% target sealing compliance rate: a worked example

This scenario runs the sealer coverage calculation on the strong side: 99% target sealing compliance rate, with every other input held at its documented default. Use it when sealer coverage in stone, countertops and engineered surfaces needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Slabs or tops sealed correctly: 8 count (unchanged)
  • Total slabs or tops requiring seal: 250 count (unchanged)
  • Target sealing compliance rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Sealer coverage rate = sealer coverage count ÷ total sealer coverage population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for sealer coverage rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for sealer coverage gap to target.
  • At this operating point the engine returns 8 count for sealer coverage count.
  • At this operating point the engine returns 250 count for total sealer coverage population.

How this compares with the baseline

  • Against the tool's baseline example, where target sealing compliance rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it during QC audits, monthly install reviews, or when investigating a spike in stain and etch callbacks. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Sealer coverage rate: 3.2 % (headline result)
  • Sealer coverage gap to target: 95.8 points
  • Sealer coverage count: 8 count
  • Total sealer coverage population: 250 count
