Staining Self-leveling concrete

Self-leveling concrete can be a great surface for staining, as it is smooth and level with few surface irregularities. There are two main types of stains for SLC: acid-based stains and water-based stains. Both types of stains can create unique and beautiful finishes, but they have different application methods and final appearances.

Can you stain self-leveling concrete?

Yes, you can stain self-leveling concrete! Staining SLC is an effective way to add color and depth to a space, as well as to make it more visually interesting. Stains penetrate the surface of the concrete, creating a long-lasting color that won’t peel or flake off.

Can you acid stain self-leveling concrete?

Yes, you can acid stain self-leveling concrete! Acid staining is a chemical reaction that causes a chemical reaction with the minerals in the concrete, creating a unique color that can’t be replicated with other methods. The acid reacts with the concrete’s calcium hydroxide, creating a variety of earthy tones such as browns, tans, and greens. The final appearance can be mottled or marbled, depending on the specific technique used.

Selecting the right type of stain for SLC

When selecting a stain for SLC, it’s important to consider the type of stain that will work best for the specific project. Acid stains create a permanent color, whereas water-based stains create a semi-translucent, variegated finish.
