Concrete cracks need assessment before a garage floor is coated. Describe the crack's location, condition, and any observed change or moisture. The provider should identify the repair scope and its limits; a decorative coating does not establish that substrate movement has been resolved.
Photograph the condition before filling anything
Take a wide photograph and close-ups showing the line and its edges. Note whether it has changed, whether water appears, and whether adjacent concrete is displaced. If structural movement is a concern, ask whether another qualified assessment is needed before coating.
Separate cracks from intentional joints
A saw cut, a separation beside a wall, and an irregular crack may require different treatment. Discuss garage floor expansion and control joints separately from crack repair. The provider should identify each feature and its proposed detail.
Get repair assumptions into the quote
Record preparation, repair material, included damaged areas, and the process for extra work discovered after old coating removal. Ask which conditions could remain visible or reappear if the slab moves. Sika's preparation guide describes substrate repair as part of preparing for a flooring system; follow the actual products' instructions.
Read the repair and warranty together
Ask whether the warranty addresses a repaired crack reopening and who handles a claim. Keep the photographs, scope, and product details. Use the garage floor quote checklist to compare repair assumptions before hiring.
Request a review of your cracked garage floor with photographs, city, approximate area, and any observed changes.
