Concrete Acid Stain Black 1 Gallon
Brand: Concrete Floor Supply. Features include a natural marbling effect and a chemical reaction that makes the stain permanent. This is a professional-grade product designed for ease of use by non-professionals alike. Best for small to mid-size interior spaces such as living areas or basements where a dark, dramatic finish is desired. Caution: applying to heavily textured surfaces may yield uneven results without proper surface prep.
Acid Concrete Stain Professional Grade – Black Walnut, 1 Gallon

Suitable for indoor and outdoor use and UV-stable to maintain color in sunlight. The variegated finish highlights the natural character of the concrete. Choose this if you want a true black-to-walnut spectrum with a durable, long-lasting result. Limitation: result depends on surface prep and lime content for best marbleized differentiation.
Tru Tint by Walttools Ebony 1 Gallon

Can be sprayed, brushed, or sponged on standard concrete, vertical surfaces, or overlays to achieve varied effects.

Limitation: as with all acid stains, outcome depends on concrete composition and proper application technique.

It’s designed to be easy to apply and maintain, making it suitable for homeowners and professionals alike who want durable color on floors, patios, and decorative concrete surfaces.

Best for interiors where a dark, translucent finish is desired with easier cleanup and greater environmental safety. It can be diluted to control color intensity and is suitable for floors, patios, countertops, and vertical surfaces. Caution: color may appear lighter on highly porous concrete, so testing is advised.
Buying Guide
- Surface prep: Acid stains react with lime in concrete. Proper cleaning and neutralization are essential for even color and longevity.
- Application method: Stains can be sprayed, brushed, or rolled. Choose a method that fits the space, your skill level, and desired finish.
- Color depth vs. porosity: Darker looks depend on lower porosity; porous surfaces may take longer to mature and show more variation.
- Indoor vs outdoor use: UV-stable formulas resist fading outdoors; interior options often emphasize low odor and VOC safety.
- Durability and sealing: Sealing after color development protects the finish; select compatible sealers that enhance color while preserving the marbleized effect.
- Test area: Always test on a small, inconspicuous area to confirm the final appearance before full application.
FAQ
- Are black acid stains permanent?
Yes. Acid-based stains chemically react with the concrete to produce a permanent color that does not peel like paint.
- Can I use these stains indoors and outdoors?
Many formulas are suitable for both, but outdoor use often benefits from UV-stable formulations to maintain color over time.
- Do I need a sealer after staining?
Sealing is recommended to protect the color and enhance durability. Use a sealer compatible with your stain type.
- What’s the difference between acid-based and water-based stains?
Acid stains react chemically with lime to create variegated, permanent color, while water-based stains rely on pigments and are typically easier to work with and lower odor.
- Can I achieve a solid black look?
Acid stains produce variegated finishes rather than perfectly uniform solid colors. For a deeper, more uniform effect, multiple coats or a different product type may be needed.
- Is testing necessary?
Yes. Testing on a small area helps predict color depth, pattern, and application behavior before committing to the entire surface.
