Any tips to make polished floor renovation?

Hi everyone!I'm currently renovating my flat and looking to transform my floors into something sleek and polished. I thought it would be great to start a discussion on the best ways to achieve that polished, elegant look.Here are a few tips I’ve come across:

1. Material Choice: Hardwood, polished concrete, or luxury vinyl tiles can offer that glossy, high-end finish. What has worked best for you?
2. Surface Preparation: For floors like hardwood or concrete, sanding is essential. Have you found any tools or techniques that give a smoother result?
3. Sealing & Finishing: Whether you choose polyurethane, wax, or oil finishes, what’s your preference for durability and shine?

I’d love to hear your thoughts, experiences, and any recommendations on floor polishing and renovation. Any advice on keeping the floors looking pristine over time would also be appreciated!Looking forward to your input!
