Concrete Overlay Calculator
Calculate concrete overlay material requirements for your project. Estimate coverage, bags needed, and total cost for resurfacing concrete surfaces.
Step 1: Project Area
Understanding Coverage
Coverage depends on surface area and overlay thickness. Thicker overlays require more material but provide better durability and can cover more imperfections.
Step 2: Material Details
About Concrete Overlay
Concrete overlay is a thin layer of polymer-modified concrete applied over existing concrete. It’s used for decorative finishes, surface repairs, and extending concrete life.

Cost Breakdown by Area
Concrete Overlay Formula
Bags Needed = (Area / Coverage per Bag) × Thickness Factor
The number of bags is calculated by dividing the total area by the coverage per bag, then adjusting for thickness. Different overlay types have different density and coverage characteristics.
