ACID STAINS. WATER-BASED STAINS

Stain Concrete Flooring Ideas- Aspects of Concrete Stains

Concrete staining comes in two broad types: chemical stains based on acid as well as water-based acrylics. Both types of stain may be applied to fresh or old , plain or colored concrete. They are especially effective in improving dull, dull surfaces. Since they penetrate concrete’s surface, the majority of them have outstanding durability and UV stability and can be used on concrete that is both outdoor and indoor.

Applications include:

  • Patios and walkways
  • Floors of the family room
  • Kitchen countertops
  • Surfaces that are vertical like fireplaces, walls, or walls

The majority of acid stainings consist of hydrochloric acid, water and metallic salts that are acid-soluble. They function by penetrating the surface and chemically reacting with the calcium hydrated (calcium hydroxide) within the concrete. The acid contained in the stain softly smudges surface which allows the metallic salts to get into the concrete more easily. When the stain is able to react with the concrete, it is a permanent element of concrete. It won’t fade, chip or peel off. The color palette of staining with acid-etch is usually limited to earthy colors including tans browns, terracottas along with soft green-blue tones.

If you’re looking to go beyond the delicate dramatic and subdued earth toned palette of acid staining look into water-based staining available with a wide range of colors. The majority of manufacturers provide a variety of colors in standard shades, including white and black as well as metallic tints. Similar to acid stains, water-based staining (typically composed of acrylic pigments and polymers) penetrate concrete and create permanent colors which can range from transparent to opaque based on the specific product.

As with wood staining Concrete stainings are semi-transparent and are meant to highlight rather than conceal the appearance of the concrete. They won’t cover up blemishes, cracks, or other imperfections that exist in concrete. Also, they will not completely hide the color of the concrete or hide the surface’s texture. Concrete slabs that have large cracks or spalling is generally not a great option for staining since any patchwork will be visible in the stained area.

Since stains need to soak into concrete to reach complete color saturation and full color saturation, they should not be applied to surfaces that are covered with anything that might hinder stain’s penetration, including grease, dirt coatings, glues curing membranes and sealers.
