A clean two-car garage with sound concrete is a different project from a larger garage with old paint, cracks, oil staining, or moisture concerns. That is why a proper estimate matters.
The goal of a cost guide is not to promise a number without seeing the floor. It is to explain what changes the price so you can compare quotes intelligently.
Main cost factors
Surface prep is one of the biggest value drivers. A low quote that skips grinding or ignores cracks can cost more later if the coating peels or fails under hot tires.
- Garage square footage and layout
- Concrete grinding and surface preparation
- Crack repair, divot repair, and edge detailing
- Old coating or paint removal
- Base coat, flake broadcast, and top-coat selection
- Return-to-use requirements and project timing
Epoxy vs polyaspartic pricing
Product chemistry can affect price, but it should not be evaluated alone. A polyaspartic top coat may cost more than a basic coating, but it can add UV stability, faster cure, and durable performance.
A quote should clearly state what system is included. Ask whether the price includes grinding, repairs, full flake coverage, and the final clear coat.
How to compare estimates
Compare scope, not just total price. Look for the prep method, coating layers, crack repair assumptions, timeline, maintenance guidance, and warranty language if provided.
Avoid any contractor who claims exact pricing without seeing the slab. Photos can help, but an on-site or detailed estimate is the safest way to understand the job.
