What is the cost to make concrete look like marble?

The cost of acid-stained interior flooring begins at $0.51 per square foot, which is significantly less than marble or common decorative flooring options. It can rise as high as $10.00 per square foot with highly intricate design work.

Unlike wood, tile, and carpet, which require professional installation, homeowners can manage costs by acid-staining concrete flooring themselves! Use the Direct Colors Cost Calculator to estimate your project cost.

4 Basic Considerations For Concrete Stained Like Marble

1. Selecting Acid Stain Colors

Whether you are inspired to replicate the natural color of marble or match concrete color with your existing home decor, it’s essential to test your intended slab before committing to a fully-scaled project. Concrete stains are highly versatile but depend upon consistent surface conditions to fully mimic the look of natural marble. 

Use an Acid Stain Trial Kit to test different techniques and colors in order to achieve the exact look and finish you have in mind. Remember to follow all steps for surface preparation prior to testing.

The  “marbling” effects achieved through acid staining are easier to create and more pronounced on clean, smooth concrete.

2. Surface Preparation

Surface preparation is the most important step in any acid staining project. Dilute Concrete Cleaner & Degreaser with water to a medium concentration and scrub the surface with a soft nylon bristle brush (or power wash using a low setting). Thoroughly rinse the surface with clear water to remove any remaining cleanser. Use a shop vacuum, mop, and/or squeegee to contain the water and aid in drying.

Sometimes a simple scrub is all you need to reveal a fresh canvas, however, fully removing surface adhesives can be more problematic. That’s why we rely on Mastic Remover for clean removal of any lingering industrial glues. Similarly, if you’re working with excessively smooth concrete, such as a garage floor, we recommend CitrusEtch™ Concrete Etcher to enhance concrete porosity and penetration of the acid stain.

In extreme circumstances, when the concrete does not otherwise respond to basic surface preparation, a quick Concrete Overlay will provide you with a ready-to-stain layer of concrete.

3. Stain Application

The process of acid staining will always yield one-of-a-kind permanent coloring and variation that is greatly influenced by the composition of the concrete and stain application. 

For subtle marbling effects, cover the entire floor with one color and spot stain with a diluted version of the same color or introduce a second color. This technique is called wet on wet layering.

Applying your acid stain with a pump-up applicator is the most popular option, although mixing and pouring it from a bucket is also a popular and effective approach.

Combining various techniques allows users more control and creativity. As in the case of a “washed” surface look, pooling in various areas allows the strength of the stain to be intentionally enhanced or diluted, resulting in a water-swept look.

4. Sealer Application

When choosing a sealer, the most important consideration is whether or not the concrete will present a slip hazard when wet. Interior surfaces that do not see heavy foot traffic may be sealed with our Water Based Acrylic Sealer in either a “High Gloss” or “Satin Finish.”

All outdoor concrete will eventually get wet and should therefore be sealed with a Satin Finish Solvent Based Acrylic Sealer, which is not as slippery when wet. If a high-gloss finish is essential to your intended look, consider using Non-Slip Additive in the second coat to prevent dangerous surface conditions in the presence of water.

How Do I Make Concrete Look Like Marble?

Other than having a true marble slab, the most natural-looking and durable marble-like option is to use concrete Acid Stain. Unlike paint, concrete stain penetrates deeply into the concrete surface, producing a fade-resistant, permanent color that won’t flake off or peel away. Whether you want a smooth or textured finish, staining concrete to look like marble gives you the appearance of expensive marble without the added cost of caring for and maintaining real marble.
