Create a border around your loft floor with paint. Use stencils to apply a pattern. Apply two rows of painter's tape and fill in the middle to create a stripe border. Apply one border that spans the entire loft area to pull the room together or form separate borders throughout a large loft to segment different spaces for different uses. For example, make a square border for your dining area and a large rectangle for the living room.
Use area rugs to decorate the floor of your loft to both soften the space's appearance and divide it up into different sections. Select area rugs that complement one another but are not the same when breaking up the loft space into different areas. Place one large area rug in the center of the loft floor when the room is not multipurpose.
Cover the entire loft floor with a painted pattern to bring an artistic vibe to your loft. Use any type of paint as long as you protect it with several layers of clear urethane sealant.
Paint your loft floor a solid vibrant color, whether it's wood or concrete, if you want to create a festive atmosphere.
Install wall-to-wall carpeting if the original loft floors don't match your tastes. Select a neutral carpet color that goes with almost anything if you think you may redecorate in the future.
