Flooring for indoor garages is crucial for durability, ease of maintenance, and aesthetic appeal. Common materials include concrete, tiles, carpet, and epoxy coatings. Concrete is the most common choice due to its strength and resistance to vehicle traffic and chemicals. Tiles offer a variety of colors and styles, while carpet can provide comfort underfoot but requires more maintenance. Epoxy coatings provide a glossy finish and protect the floor from stains and wear.
