BEFORE YOU HIRE
How to choose among the epoxy floor coating contractors the assistants name
- Ask which licence or registration the company holds for this work, and confirm it with the state or city. Licensing rules differ by city and by job size.
- Ask for a certificate of insurance that names your property, and confirm it with the insurer.
- Ask for two or three references from similar commercial jobs and call them.
- Ask how they test the slab for moisture, how they prepare the surface, and which coating system and thickness they propose for your traffic.
- Get the scope, products, schedule and warranty in writing, and compare at least two proposals on the same scope.
METHOD AND LIMITS
