Staining concrete floors is a project most DYI folks can do themselves. Staining concrete is easy and the beauty it adds to a room or patio is spectacular. We sell Mason's Select Transparent Acrylic Concrete Stain, it works great and comes in eight standard colors that can be intermixed if you want more choices. As with coating all concrete, your slab must be at least 30 days old. Next you will want to check for excessive moisture coming through the slab.
