Acid Staining

 

Description

Acid staining is often referred to as coloured concrete.  Concrete has porous qualities and as a result is an ideal medium for topically applied colour.  Using acid-based chemical stains, the professionals at Barrier Coatings are able to achieve rich, earth-toned colour schemes resembling natural stone, giving a completely custom look to concrete floors, driveways, patios, walkways, pool decks and more.

 

Acid staining works by penetrating the surface and reacting chemically with the hydrate lime (calcium hydroxide) in the concrete.  The acid in the stain lightly etches the surface, allowing the metallic salts to penetrate more easily.  Once the stain reacts, it becomes a permanent part of the concrete and won’t fade, chip off, or peel away.  Like stains for wood, acid-based stains are translucent and the colour they produce will vary depending on the colour and condition of the substrate they are applied to.  Each concrete slab will accept the stain in varying degrees of intensity, creating natural colour variations that bring character and distinction to each project.

 

These sample colors from Kemiko Decorative & Industrial Floor Finishes products can give you an idea of the types of hues available for staining concrete. Stains provide natural color and depth to concrete floors and other surfaces.
