Acid stained concrete is a decorative application. Colors are earth tones of brown and green. The most popular is brown which resembles the look of worn leather.
The stains produce a muted appearance, which are drastically enhanced with application of a seal coat.
How Do You Stain a Concrete Floor?
Acid stains come in liquid form. They are a mix of hydrochloric acid, metallic salts and water. Coloring becomes part of the concrete.
The acid open the pores of the concrete surface allowing acid soluble metallic salts to react with the lime in concrete.
This is very different than paints or coatings which cover the concrete.
The natural variation of concrete is exposed. Once the acid stains are applied, a seal coat is sprayed and rolled on the surface. The final seal coats are what make the floor pop exposing the beauty of the floor.
Acid Stained Concrete Cost
Expect to pay in the range of $1.50 to $4.50 per square foot depending on the size and condition of the floor.
Pricing will increase for decorative options. Shallow saw cuts creating the look of custom tile with borders are very popular. Areas with borders and patterns can be stained with custom colors. This will increase the overall cost due to extra labor and skill.
The decorative concrete staining contractors at Armor Prep are skilled artists. They know how to layer the stains and various colors to create decorative floors for home and business use.
Can All Concrete Be Stained?
There are solutions for problematic surfaces. In some cases floors may have had sealers applied or admixtures in the concrete when originally poured. These can block the ability of acid stains to react with the lime.
The solution may be to grind the surface, then stain and seal. This is called Grind and Seal. You may have seen a Grind and Seal floor in a restaurant or retail store. They are very popular due to the cost, low maintenance and decorative appearance.
If the floor is damaged or uneven, a thin overlay or self leveling concrete can be applied. The the new surface can be stained and sealed.
What is The Cost to Maintain a Stained Concrete Floor?
Use low abrasion cleaners to prevent scratches or wear through the sealer.
High solids wax coats can be applied for under 10 cents per square foot. High solids wax coats are available with 25% or more solids. They can also be diluted with water.
Apply 1 – 2 coats with a micro fiber mop. They can also be buffed with high speed burnishers enhancing protection, ensuring long term durability
Basic polished concrete can range from $1.75 to $5 per square foot depending on the size, condition and level of polish desired.
More elaborate, decorative polished concrete can range from $5 to $10 or more.
What Are The Factors Affecting the Cost of Polished Concrete?
Concrete polishing equipment comes in various sizes.
Hand Grinders – For tough to reach areas near walls and columns, hand grinding is the best option. The process starts with course pads to break through the top layer. Then numerous steps in the process are used to grind and hone the surface.
Small Upright Machines – Small is a relative term when referring to polishing equipment. A small machine can be 300 lbs. Each machine also has a high powered industrial dustless vacuum. Both the polisher and vacuum can be powered by a portable generator.
Each polisher uses different diamond grinding pads. They start with course pads ranging from 25-50 grit. Then the pads are changed to 50-100 grit, 200, 400, 800, 1500 and 3,000 grit.
Polishing concrete is a multi step process working from course pads to finer ones.
A 300 lb machine will not produce the same level of polish as a large industrial machine. The additional weight makes a significant difference in outcome.
Small areas like basements or garages can benefit from the Grind & Seal finish. Frequently what starts as a polishing requirement ends with a grind & seal finish, an overlay or epoxy.
Large Upright Machines – These can be 1,000 lbs or more. They are used primarily in commercial areas. Restaurants, Retails Stores, Offices, Showrooms and warehouses are popular uses.
Available Concrete Polishing Options
There are many choices available depending on your desired appearance, budget, condition of the floor, size and access.
Due to the high demand of polished concrete, numerous options have evolved.
• Floor Grinding and Sealing – Grind and seal can be a decorative or utility finish. Use as a first step for surface prep for tile, hardwood, carpet or moisture mitigation. They can be sealed with epoxy coatings, urethanes or polyaspartics.
• Metallic Epoxy Coatings – Metallic epoxy produces a marbleized stained concrete appearance with a gloss like on a polished surface. Numerous colors are available as well as custom designs.
• Polished Concrete Overlays – Many overlays are available from thin coats of 1/16th inch thick to 3/8 inch thick. These are ideal when a new surface is needed for floor height needs to be increased.
Epoxy floor coatings have broad uses with specialized features. They should not be compared to the thin, epoxy paints you find at your local home improvement store.
Metallic epoxy, in particular, should not be confused with a typical decorative chip epoxy floor coating. Chip epoxy coatings are a high performance industrial look. They range in price from $4 per square foot to $7 per square foot depending on size and appropriate system.
Metallic epoxy floor coatings, on the other hand, range in price from $6 to $12 per square foot.
To give you an idea of total cost, here are sample uses and sizes with price based on actual square footage.
There are other industrial systems that cost even more than $10 per square foot for chemical resistance features especially useful for commercial and industrial applications.

What Is Metallic Epoxy Flooring?
Metallic epoxy is a high performance liquid coating. It is 2 parts resin and hardener that are mixed together then rolled or squeegeed onto concrete surfaces. It is protected with a clear urethane creating a smooth finish.
A metallic pigment is added creating an amazing appearance with tremendous depth. Numerous colors can be combined for a marble like appearance.
Is Metallic Epoxy a Durable Coating?
Metallic epoxy is a two-coat, 100% solids liquid floor coating. They are finished with high performance clear coat urethanes. They are extremely durable.
One of the benefits of Metallic Epoxy Floor coatings is they combine industrial strength with a high decorative curb appeal enhancing finish.
