Frequently Asked Questions
What is the difference between polished concrete and grind-and-seal?
Polished concrete is mechanically ground and refined with progressively finer diamonds plus a densifier, creating a durable, glossy surface. Grind-and-seal grinds the slab and then applies a topical sealer; it costs less but the sealer needs periodic maintenance.
Can you remove old coatings, glue or adhesives from concrete?
Yes. We grind off existing coatings, mastic and adhesives to leave a clean, profiled surface ready for polishing, coatings or new flooring.
Is polished concrete a good option for commercial spaces?
Yes. Polished concrete is low-maintenance, resists heavy foot traffic and reflects light, which is why it is popular in retail stores, offices, showrooms, hallways and warehouses.
