Stained & sealed concrete is a great flooring option for new homes. It is a stylish, functional, and economic flooring option that also offers ease of maintenance on the owners part. The best time to install this flooring in the construction process is toward the end of the process, after base trim has been installed and painted. It is very important that if you choose this option as your flooring that you cover the floor (Builder board or Ram Board) during the building process to protect it from paint, spray foam, glue or mastic's, sheet-rock mud, tire marks, general spills. If the concrete is not covered it could cost more to prepare the slab for staining. Please contact us for answers to all of your questions.
