Find out where the water actually goes
Look at the floor after a wet vehicle is parked or after a controlled rinse. Does water move toward the door, a center drain or a channel drain? Does it stop in a low area? Record those observations before the estimate. A dry floor can hide a drainage problem that becomes obvious after the first snowmelt.
Do not ask a coating contractor to bury a low spot under extra topcoat. The finish is designed for protection and appearance, not for reshaping the slab. If the water path is wrong, request a separate concrete or drainage repair recommendation.
Three details that belong in the scope
| Location | What to agree on |
|---|---|
| Floor drain | How the drain ring is prepared, how the coating ends, and whether the grate remains removable. |
| Garage-door threshold | The exact termination line, edge preparation and treatment of any weatherstrip or channel. |
| Control or expansion joint | Whether it moves, how it will be treated, and whether the line will remain visible. |
Sherwin-Williams publishes separate resin-floor details for drains, channel drains, terminations and movement joints. That is a useful reminder: these edges have their own construction details, not just a quick pass with a roller. The detail used in your garage must match the selected product and the actual drain.
Joints are not decorative lines
Some concrete joints are intended to accommodate movement. Others are saw cuts or static construction details. The treatment differs. Sherwin-Williams' joint guidance distinguishes moving from non-moving joints and calls for compatible treatment. Ask which lines will be filled and which will remain functional. A promise that every line will disappear may not be realistic.
Choose texture with wet use in mind
Full flake and added traction aggregate change how the floor feels under wet shoes. More texture can help grip, while a smooth finish may be easier to mop. Ask to handle a sample of the actual finish and to learn the cleaning method. A picture of a glossy floor cannot tell you how it will perform with slush or wash water on it.
If you regularly hose the garage, point that out. The contractor should know how much water the floor sees and where it exits. The Sika flooring guide explains the basic relationship between floor fall and drainage; although written for commercial wet areas, the physical principle applies to a garage too: water moves toward a lower outlet.
Use this five-minute walkthrough before requesting quotes
- Take a wide photo showing the whole floor and garage door.
- Photograph the drain ring, channel or threshold close up.
- Mark where water ponds after a wet car comes in.
- Point out cracks and joints that cross the water path.
- Ask the estimator to describe the drain, joint and doorway details in the written scope.
This is particularly useful for homes in Cicero or Southport where the owner has a drain or a wet threshold. The same checks apply anywhere in the service area.
