Garage Floors

Epoxy, polyaspartic, floor paint, tiles and mats: preparation, moisture testing, coverage, costs and what lasts longest.

A finished floor changes how the whole garage looks and works. These guides compare epoxy, polyurea, polyaspartic, floor paint, interlocking tiles and mats, and explain the moisture testing and preparation that decide how long any coating lasts.

How to use this topic

  1. Test the slab for moisture first; ASTM D4263 uses a taped plastic sheet to indicate capillary moisture.
  2. Choose a coating, tiles or mats based on the slab's condition, how you use the garage and your budget.
  3. Plan prep: degrease, grind or etch, fill cracks and vacuum.
  4. Estimate materials with our calculators before buying.
