 Warehouse Concrete Floor After Cleaning & Before Acid-Staining
 Warehouse Concrete Floor Cleaned and Masked Off Before Acid Staining

This is the truck and machinery repair area of a 3,200 square foot warehouse in Ray Township, MI.  The owner of the company wanted it sealed so that oil and vehicle fluids wouldn't stain the concrete.  The first photo (above left) shows the floor at the outset; the next photo (above right) shows the floor after cleaning.

Acid stain was used for coloring the floor, rather than epoxy, so the color would be "in" the concrete and could not peel off.  The color is "Mahogany", from Artcrete.  A polyurea clear sealer was used to protect the floor, as it would be much more chemical resistant than epoxy or urethane.  The two photos (above) show the floor after staining and then after sealing.

The last two photos (above) show the floor from a different angle.  The last photo (above right) shows the glass bead aggregate that was added to the final coat of sealer for slip resistance.  Glass bead help prevent slips and falls on wet concrete flooring but is transparent, so it doesn't obscure the coloring.
