Carpet? Tile? vinyl flooring? Wood? Paint? What do you want to achieve?
I would use cement paint and stencil a great design on it. Amazon has a ton of stencils.
I painted my basement cement floor with a teal colored cement paint and it came out great. If you are talking about a finished basement I love the new tiles that look like wood.
Hi.. I would Suggest you to give a new look to your basement with the Engineered Parquet Flooring . Engineered Wood Flooring not only gives a classic and elegant look to your Basement but also adds overall value to your House.
