EverStain™ Acid Stain is a professional-grade concrete acid stain that creates permanent, variegated color through a chemical reaction with the cement minerals in your concrete. Unlike paints, dyes, or topical stains that sit on the surface, EverStain reacts with the concrete itself — producing rich, marbled, translucent color that becomes part of the slab and can never chip, peel, flake, or wear off.

Every concrete acid stain application is one-of-a-kind. Because EverStain reacts with the unique mineral content of each individual concrete surface, no two floors look exactly alike. The result is the deep, organic, variegated look that makes acid-stained concrete the gold standard for decorative concrete floors, patios, countertops, and architectural surfaces.

Why Acid Stain Concrete Instead of Paint or Dye

Concrete acid stain produces results that no paint, dye, or topical stain can replicate:

• Permanent color through chemical reaction — EverStain reacts with calcium hydroxide in the cement to form insoluble metallic oxides locked into the concrete matrix. The color is part of the concrete itself.
• Variegated, translucent, marbled finish — Acid stain reveals the natural character of the concrete underneath. Highs, lows, trowel marks, and surface variation become part of the finished look.
• Cannot chip, peel, or flake — Because the color is chemical, not topical, there's nothing to delaminate. Acid-stained concrete looks better with age and wear.
• Translucent — works with existing concrete — EverStain enhances and colors existing concrete rather than covering it. You see the soul of the slab through the color.
• Decades of proven performance — Acid staining has been the professional standard for decorative concrete since the early 1900s. It's the technique architects, designers, and high-end builders specify when they want a finish that lasts.

Sealer Required: Why EverStain Needs a Concrete Sealer

Every concrete acid stain — including EverStain — must be sealed after application. Here's why this matters:

While the EverStain reaction creates color that's chemically permanent and locked into the concrete, the color appears faint, dusty, and washed-out until it's sealed. The sealer is what makes acid-stained concrete "pop" — it deepens the color, brings out the marbled variegation, and reveals the rich, saturated tones the reaction has created underneath. Without sealer, you get a fraction of the visual impact your acid stain is capable of producing.

Sealer also protects the concrete surface from staining, water damage, abrasion, and UV exposure. For interior floors, a sealer-and-wax finish creates a low-maintenance surface that handles foot traffic, spills, and cleaning for years. For exterior patios, sealing locks in color saturation and protects against weathering.

This is why Direct Colors sells EverStain in 3-Step Systems that pair the acid stain with the right sealer and ProClean™ Neutralizer in matched quantities. If you're not sure which sealer to choose for your project, the system bundles take the guesswork out — see the EverStain™ 3-Step Acid Stain System for the complete kit.

What EverStain Acid Stain Is Used For

Interior concrete floors — Living rooms, kitchens, basements, sunrooms, retail spaces, restaurants, and commercial flooring where customers want the warmth of natural concrete with permanent color. Acid-stained interior floors are a standout look that costs less than tile, hardwood, or polished concrete and lasts longer than any of them.

Exterior concrete patios — Backyard patios, courtyards, outdoor entertaining areas, and garden hardscape. EverStain handles weather, freeze-thaw, and UV exposure when properly sealed.

Concrete driveways and walkways — Curb appeal that lasts. An acid-stained concrete driveway is a permanent upgrade that survives years of weather and tire wear.

Pool decks — Cool, slip-resistant (when sealed with OxiGrip™ additive), and beautiful. Pool deck acid staining is one of the most popular high-end backyard upgrades.

Concrete countertops — Acid stain on concrete countertops creates a one-of-a-kind kitchen or bath surface. EverStain works on cast and cast-in-place concrete countertops.

Garage floors — A stained and sealed garage floor handles oil, gas, dirt, and tire traffic far better than paint or epoxy and won't peel under hot tires.

Vertical surfaces — Stained concrete walls, fireplace surrounds, and architectural features. (For vertical applications, DecoGel™ Acid Stain is the gel-formula version designed to stay put on walls without dripping.)

For best results, always test EverStain on an inconspicuous area or sample piece of concrete from your specific slab before committing to a full application. The EverStain™ 3-Step Trial System is the most reliable way to test colors before you buy a full gallon.

How to Acid Stain Concrete with EverStain

Acid staining concrete is a 3-step process: prep, stain, and seal. The full process is documented in the Direct Colors Acid Stain How-To Guide, but here's the overview:

1. Surface prep — Clean and degrease the concrete with ProClean Degreaser™. For sealed or contaminated concrete, use CitrusEtch™ to open the pores so the acid stain can react.
2. Apply EverStain Acid Stain — Spray on with a plastic pump sprayer. Work the stain into the surface with a soft-bristle brush for even coverage. Allow the chemical reaction to develop (usually 4–24 hours depending on temperature and humidity).
3. Neutralize the reaction — Use ProClean Neutralizer™ to stop the acid reaction and prepare the surface for sealing. Rinse thoroughly.
4. Seal the concrete — Apply your chosen concrete sealer to lock in the color and protect the surface. The sealer is what makes the color "pop" — without it, the stain looks dull and dusty.
5. Optional final coat — For interior floors, finish with ProWax Polish™ for a low-maintenance, high-traffic finish.

EverStain Coverage and Sizing

EverStain Acid Stain is sold by the gallon and covers approximately 150–200 square feet per gallon, depending on concrete porosity and desired color depth. For most projects, plan on one gallon per 200 sq ft of standard interior or exterior concrete.

For larger projects, EverStain is also sold in 5-gallon containers as part of the EverStain™ 3-Step Professional System, which covers 1,000 sq ft and includes matched quantities of sealer and ProClean Neutralizer.
