3) What is polished concrete?

Polished concrete is a multi-step mechanical process that transforms ordinary concrete into a smooth, reflective, and durable surface. It’s ideal for modern homes, retail spaces, warehouses, and restaurants.

4) What is the difference between epoxy and polished concrete?

Polished concrete refines your existing slab to a shine, while epoxy flooring is a protective coating that can be decorative, chemical-resistant, and seamless. Epoxy offers more design options (flakes, metallics), while polished concrete offers a sleek, natural look.

5) How long does installation take?

Most projects between 1,000–20,000 sq. ft. are completed in 1–3 days, depending on the floor’s condition, required repairs, and the chosen finish.

6) Do you offer moisture testing and barrier systems?

Yes — we recommend moisture testing before epoxy installation. We also install moisture mitigation systems to protect your investment.

11) How do I maintain my floor?

Sweep regularly, damp-mop with a neutral pH cleaner, and avoid harsh acids. We can provide periodic maintenance or resealing as needed.

12) Do you repair cracks or uneven concrete?

Yes — we include crack repair, leveling, and grinding in our prep work to ensure the best results for polishing or coating.

13) How long does epoxy take to cure?

Light foot traffic is usually possible after 24 hours, but full curing for vehicle use and heavy loads takes about 72 hours.
