TRIPLE-S Concrete Acid Stains

Triple-S Chemical Concrete Staining Products specializes in concrete acid stains, patinas and antiquing solutions for metals. We are a small and independent company based in Los Angeles, California for over 25 years.


Triple-S Concrete Acid Stains contain inorganic salts dissolved in water, which react with the minerals within concrete. Our stains penetrate the pores in concrete and chemically react with contained minerals to form a durable and permanent color that will not chip, peel, or flake. A great variety of attractive and unique colors result in giving your floor a beautifully aged look.


Triple-S Concrete Acid Stains are designed to create beautiful colors on new or old concrete. Each concrete slab accepts the stain in varying degrees of intensity creating stunning multi-hued color variations, often in an uneven finish that looks perfectly aged.


Concrete Acid Stains surpass all other concrete coatings in terms of resistance and long lasting durability. They will not chip, fade or peel off the surface to which they are applied. Their longevity is even furthered when floors are sealed and/or waxed.


Triple-S Concrete Acid Stains are meant to be used as is but artists can also create their own shades of color by using a mixture of several colors. Testing is always recommended. Our acid stains were developed to decorate patios, building exteriors, drive-ways, garage floors, basement floors, entrances, living rooms, side-walks, restaurant floors, entrance ways, commercial malls and plazas. The uses are limitless.


Each gallon of acid-based concrete stain product covers approximately 200-250 square feet depending on the porosity of the concrete.

In order to be stained, new concrete must cure for at least 3-4 weeks. Old concrete should be free of any sealer, oil, grease, paint, dust and any other coating which might prevent penetration. The best way to prepare the concrete is usually by grinding or sandblasting. DO NOT use any acids or chemical agents to prepare the concrete.

Concrete acid stain solutions can be applied by spraying, brushing or rolling. The best method of application is however, to spray the solution with a plastic sprayer. Avoid puddles and brush out pooled stain. Allow stained areas to dry evenly. A second coat can be applied after 4 hours, if desired, to darken the reaction. We strongly recommend testing a small area before doing the whole project.

Before sealing or waxing, the acid stain must be neutralized with an Ammonia and water mixture (approximately 1 quart of Ammonia in 5 gallons of water). Apply either with a mop or a sprayer and then remove with a wet-vac or a mop; this process will neutralize the chemical reaction and the acidity of the stain. A final wash with water is recommended to fully remove any and all residue from the neutralizing solution. After the final rinse, allow a full 24 hours to dry before sealing or waxing.

To protect the stain and provide long lasting durability, it is important to seal the stained concrete area with some type of sealer. For light interior traffic, we recommend 2 coats of our clear water-based lacquer, WSL-45 flat or gloss. For better durability indoors (but suitable for outdoors as well), we recommend AL-70 which also comes in a flat or glossy finish; this solvent based lacquer is more durable and water resistant than WSL-45. For medium indoor and/or exterior traffic we recommend Triple-S’ one part Polyurethane, UT-70/30. This is a very good choice for small boutiques, patios, driveways, etc however, it only comes in a semi-gloss finish. For high traffic or commercial indoor use, we recommend our 2 part Polyurethane, UT-9500. Although UT-9500 is recommended for use by professionals only.
