The best practice when selecting flooring that is safe durable and won t trap allergens may be the interior concrete slab as the floor surface.
Finished concrete flooring existing slab.
Besides the reduction of allergens in the home concrete floors last much longer than conventional floor coverings.
Acid staining can be a diy project.
The acid stains are mottled and add some visual texture to the floor so that imperfections in an existing slab don t stick out.
The big boxes sell concrete stains that are just top coats so won t give you the same look or durability that an actual acid stain will.
Many floor finishes including staining dyeing polishing and decorative coatings can be applied to existing concrete as well as new concrete.
Be sure to use actual acid stain however.
For a concrete floor with a basic finish you can expect to pay 2 to 12 per square foot if you have an existing concrete slab that s ready for staining polishing or application of a decorative coating or overlay most decorative concrete floor installations can be quite cost effective.
