Stamped Concrete Overlays

A stamped overlay offers all the aesthetic benefits of conventional stamped concrete but is applied over existing concrete. Stamped concrete overlays allow you to duplicate the beauty and texture of natural stone, brick, slate, wood, and other materials without having to replace your concrete.

A stamped overlay can be used indoors or outdoors to recreate the look of natural stone, brick, slate, or even wood.

CAN YOU DO STAMPED CONCRETE OVER OLD CONCRETE?

Stamped concrete overlays can be used on new or existing concrete and on interior or exterior surfaces. They can even be applied to walls and other vertical surfaces. They are especially popular for refreshing the appearance of existing driveways, patios, walkways, pool decks, and floors.

Before opting for a stamped overlay, consult a professional to determine if your concrete can be resurfaced successfully. If the concrete is in bad shape, with large cracks or severe settlement, resurfacing may not be a viable option.

HOW TO STAMP EXISTING CONCRETE

A stamped overlay will be durable and easy to maintain if applied properly. In order for the overlay to adhere successfully, you'll need to prepare the existing surface by cleaning it thoroughly, repairing any cracks, and profiling (which roughens the surface and helps the overlay bond to the concrete).

The overlay mix is usually applied by a gauge rake (a tool with an adjustable depth gauge for achieving a uniform topping thickness), and then imprinted with stamping mats or texturing skins. Overlay thicknesses range from 1/4 to 3/4 inch, depending on the depth of the imprint.

STAMPED CONCRETE OVERLAY COST

A stamped concrete overlay is at the higher end of the overlay products, which can range from $3-$10 per square foot, installed. Labor costs depend on the market rates in your area, as well as the size and detail of your design. Generally speaking, the smaller the surface, the higher the labor cost might be. Some contractors may even charge a flat fee for small projects.

IS A STAMPED OVERLAY A DIY-FRIENDLY PROJECT?

While it is possible to complete some concrete projects as a DIY, we recommend hiring a professional. You can find a resurfacing contractor near you in our directory.

An overlay acts in a similar fashion to new concrete, in that it has a limited time available for it to be stamped. A contractor can complete the job on time, without error, and with a final finish you will enjoy for years to come.

DURABILITY OF STAMPED OVERLAYS

When applied properly, a stamped concrete coating should last for years. It will help add strength to an existing surface, while also updating the look. Much like a newly poured patio, your overlay will need to be sealed every few years to maintain its appearance and protect it from damage.

MORE IDEAS FOR STAMPED CONCRETE RESTORATION AND RESURFACING

If you already have a stamped concrete surface that is suffering from cracks, spalling, or settling it may be a candidate for restoration and resurfacing. Some refinishing options include:

New sealer

Every few years, depending on the amount of traffic, it is recommended to apply a new sealer. For a surface that is in good shape, this will refresh the look. Depending on the type of sealer used, it can enhance the color already installed on your surface, or even give you the opportunity to add color through a tinting additive. Sealers also come in different sheen levels, ranging from matte to high gloss.

Recoloring

Changing the color of your stamped concrete can be done with different types of stains, tints, or dyes. The coloring method you choose will give you a different amount of color.

Here is a quick guide to the color adjustment levels:

• For minor color adjustment use an impregnating stain or diluted acid stain
• For medium color adjustment use a full-strength acid stain, dye, or tinted sealer
• For complete color change use an acrylic or solid-color stain

Resurfacing

Applying a concrete overlay to an existing concrete surface, in good condition, will bring a new look, and feel. The overlay will work to fix minor cracking, and add strength and durability to the surface, while simultaneously giving you an opportunity to change the stamp pattern, color or finish.
