Concrete Resurfacing Cost Calculator
Calculate how many resurfacing kits a measured slab requires using the selected product's coat count and coverage, then itemize labor, cracks and grinding.

Resurfacing is not the same scope as placing a new slab. Cleaning, grinding, crack repair, patching and surface preparation can consume a meaningful part of the job before an overlay or coating is applied.
Use the selected resurfacing product coverage per kit and coat count, with a quoted kit price. Enter crack repair, grinding/preparation and decorative finishes in their dedicated lines. Do not duplicate bundled work, and seek professional assessment for structural movement or settlement.
- Inspect and price repairs separately from the finish layer.
- Match the rate to the specified overlay or coating system.
- Do not use a cosmetic resurfacing estimate as a substitute for structural assessment.
Resurfacing material is product-specific
Concrete resurfacers vary in application thickness, working time, coverage and permitted substrates. Instead of assuming every slab needs the same pounds or dollars per square foot, enter the coverage provided by your chosen kit for one coat at the planned application thickness. The calculator multiplies measured area by the number of coats, includes any explicit quantity allowance and rounds up to whole kits. This is only valid when the entered per-kit coverage applies to each of those coats.
Do not use a thin-overlay model to budget slab replacement or structural repairs. Cracks, coatings, contamination, moisture and spalling may need preparation before a resurfacing product will bond successfully. The separate preparation and repair fields help you make those scope decisions visible instead of hiding them in the coating price.
Worked resurfacing example
A 20-by-10-foot area is 200 square feet. With two coats and manufacturer-labelled coverage of 50 square feet per kit per coat, the unadjusted requirement is eight kits. Ten percent extra material raises the requirement to 8.8 kits, rounded up to nine. At a hypothetical product price of $80 per kit, the material allowance is $720. Example labor of $3 per square foot adds $600; crack repairs of $100, grinding of $150 and decorative work of $50 make the illustrative budget $1,620. Replace those values with product data and local quotes.
Scope and product conditions
Check the product documentation for surface profile, minimum and maximum application thickness, temperature, cure time, slip resistance and any primer requirement. Some systems use multiple different coats with different coverage rates; calculate those separately rather than entering one misleading universal value. If resurfacing is not appropriate because the underlying concrete has failed, use the Concrete Cost Calculator for a replacement scenario.
For a mechanically polished surface instead of an overlay, see Polished Concrete Floor Cost Calculator. Keep materials, labor and surface preparation distinct when comparing bids.
