Stains are not a paint, coating or sealer.
Acid Stained Concrete is a coloring process
involving a chemical reaction on a cementious
material. Acid stains are made from hydrochloric
acid, wetting agents and metallic ions.
A solution made with water, acid and inorganic
salts react with mierals already present
in the concrete. When this solution is placed
on concrete it colors the concrete by chemically
combining the metallic ions with the particles
in the concrete to form oxides. The acid
in the stain opens the top surface in the
concrete allowing metallic salts in the
mixture to react with the calcium hydroxide
in the concrete.
they are acid stains, acid is not the ingrediant
that colors the concrete. Metallic salts
in an acidic, water based solution react
with the calcium hydroxide in the hardened
concrete yeilding insoluable colored compounds
that become a permanent part of the concrete.
