What is polished concrete?
Polished concrete is a durable, low-maintenance floor finish that transforms concrete into a smooth, reflective surface. It’s perfect for residential interiors, retail spaces, and commercial properties.

What is the difference between epoxy and polished concrete?
Polished concrete is created by mechanically refining your existing slab. Epoxy floors are coatings that form a seamless, decorative, and chemical-resistant surface. Each is great for different use cases.

Most projects between 1,000–20,000 sq ft are completed in 1 to 3 days, depending on concrete conditions and finish complexity.
