There are some things you should know before you start the project. The concrete needs to be completely cured, which is usually 21 days after pouring. You also need an extremely flat base with no bumps or other imperfections, but this is why you should hire specialist installers instead of doing it yourself. Another thing about polished concrete is that it is not recommended to come into full contact with the floor when it’s wet. Some people think that polished concrete can be slippery, but any natural stone surface is more likely to be slippery when wet because of the fine sand particles on the rough surfaces.
