Roughly what would it cost to coat a 2,000 sq ft Westboro store?

For a 2,000 sq ft Westboro retail store, published 2025-2026 contractor ranges put a commercial epoxy system at roughly $8 to $15 per square foot installed; multiply by your floor area for a first budget. Lighter commercial systems start at about $5 per square foot. A polyaspartic or polyurea system runs about $6 to $15 per square foot installed, and polished concrete on an existing slab falls in the $3 to $15 range, with most commercial jobs landing around $5 to $12 per square foot. Your quote will differ based on what the slab needs and which system you choose.

Several things move a quote up or down on a job like this. Surface preparation, when it is not already included, can add about $1 to $3 per square foot. Slab condition matters: cracks, old adhesive, a previous coating, or a floor that tests high for moisture all affect what the contractor has to do before the first coat goes down. Moisture testing follows ASTM F2170 (in-situ relative humidity probes) or ASTM F1869 (calcium chloride), and if the slab reads above what the product's data sheet allows, a moisture-mitigation primer is needed. We found too few published prices to give a range for that primer alone. Cove base, anti-slip aggregate broadcast, and line striping can also be priced separately, so confirm what is and is not included.

Closure time is a real cost for a retail store. One manufacturer's data sheet for a 100%-solids epoxy lists foot traffic at 24 hours and light vehicles at 72 hours; the data sheet for your chosen product governs, and the contractor should confirm the schedule against it before you plan the closure. After-hours or phased work to keep part of the store open is possible depending on the products and layout, but we found too few published prices to give a range for that premium.

Ask each contractor for the product data sheets and safety data sheets for every material they plan to use, proof of liability insurance, and references on similar retail floors.

One line worth checking in any quote for this store: ask exactly what surface prep is included in the price and what triggers an extra charge if the slab turns out to be in worse condition than it looks.
