Sealing interior concrete floors is a great contemporary look. Sealed concrete floors is a very cost affect floor that just involves cleaning the concrete and applying the sealer. There are many different sealers to choose from depending on if the owner wants I gloss finish or a matte finish. There is also the option of grinding the concrete before applying the sealer to expose some of the rocks in the concrete.
Take a look at the photo below of a recent job we completed. This concrete floor was cleaned and then had a solvent based acrylic sealer applied.
