Concrete staining costs $2 to $8 per square foot in 2026 depending on stain type, number of colors, and surface preparation requirements. A 500 square foot patio or garage floor staining project runs $1,000 to $4,000 installed. Staining transforms plain gray concrete into a rich, colored surface with unique mottled patterns (acid stain) or consistent solid colors (water-based stain) that cannot be replicated by any other finishing method.
Metal America Concrete connects property owners with licensed concrete staining contractors in all 50 states. Our network handles interior floors, patios, driveways, pool decks, garage floors, and commercial spaces. Every staining project includes surface preparation, stain application, neutralization (acid stain), and a protective sealer to lock in the color and protect the finished surface.

Types of Concrete Stain in 2026
Acid stain (also called reactive stain) creates a unique, variegated color pattern by chemically reacting with minerals in the concrete. No two acid-stained surfaces look exactly alike, which gives each project a one-of-a-kind appearance. Acid stain is available in a limited palette of 8 to 12 earth-tone colors including amber, brown, tan, charcoal, blue-green, and terra cotta. Acid staining costs $4 to $8 per square foot in 2026 including surface prep, stain application, neutralization, and sealer.
Water-based stain (also called non-reactive stain) produces consistent, uniform colors and is available in a much wider palette of 30 to 50+ colors including bright blues, reds, greens, and custom blends. Water-based stains sit on top of the concrete surface rather than reacting chemically, so they produce a more predictable result. Water-based staining costs $2 to $6 per square foot. Concrete dye is a third option that penetrates quickly and produces vibrant colors, primarily used for interior applications at $3 to $7 per square foot.
Best Applications for Concrete Staining
Concrete staining works on any existing or new concrete surface that is structurally sound and free of coatings, paint, or sealers that would block stain penetration. The most popular staining applications include garage floors ($1,000 to $3,000 for a two-car garage), basement floors ($1,500 to $5,000), patios ($800 to $3,000), pool decks ($1,200 to $4,000), and commercial retail floors ($2 to $6 per square foot for large areas).
Interior concrete staining has become increasingly popular for modern home design, loft conversions, and commercial spaces. Stained and polished concrete floors provide a durable, low-maintenance surface that eliminates the cost of carpet, tile, or hardwood while creating a distinctive look. Interior stained floors with a polished finish are among the most cost-effective flooring options when you already have a concrete slab, which most homes and commercial buildings do.
The Concrete Staining Process
Professional concrete staining follows a four-step process. First, the surface is cleaned, degreased, and any existing coatings are removed by grinding or chemical stripping. The concrete must be bare and porous for stain to penetrate properly. Second, the stain is applied by sprayer, brush, or roller in one or more coats to achieve the desired color intensity. Acid stains are left to react for 4 to 24 hours. Water-based stains dry in 1 to 4 hours.
Third, acid stain requires neutralization with a baking soda and water solution to stop the chemical reaction, followed by thorough rinsing and drying. Water-based stains skip this step. Fourth, a protective sealer is applied to lock in the color and protect the stained surface from wear, water, and UV exposure. Sealer options include high-gloss for a wet-look finish, satin for moderate sheen, and matte for a natural appearance.
How Long Concrete Staining Lasts
Concrete staining is permanent because the color penetrates into the concrete surface rather than sitting on top like paint. The stain itself will never peel, chip, or flake. The protective sealer over the stain needs reapplication every 2 to 4 years for exterior surfaces and 3 to 5 years for interior surfaces. Resealing costs $0.50 to $1.50 per square foot and takes a few hours.
Exterior stained concrete may fade slightly over many years from UV exposure, but the color remains visible and attractive long-term. Interior stained concrete in a controlled environment maintains its appearance indefinitely with regular sealer maintenance. The combination of permanent color and renewable sealer protection makes staining one of the most durable decorative concrete treatments available.
