Wood Look
If you’re in search of a flooring option that offers a range of grain textures and an endless array of color options, concrete wood look might be just what you need. Whether you prefer the traditional 4-inch wood plank or are looking for a wider plank style, wood-look concrete overlay systems can help you achieve the desired look you’re after.
Resist
Restore and protect worn concrete surfaces with the Resist Sand Epoxy System. This durable concrete restoration solution is designed to transform existing slabs while providing exceptional abrasion, impact, and wear resistance. Its unique sand-finished texture creates a slip-resistant surface that maintains long-term grip, even as the topcoat naturally weathers.

Stone
Creating a stone finish has never been easier. With our concrete overlay system, you can easily add a dimensional texture that mimics the look of real stone. By combining the overlay with a concrete stain and color wash, the finished product will feature realistic colors that really make the floor stand out.
Broomed
Broomed concrete, the ideal finish for exterior surfaces, offers increased slip resistance and durability. It is commonly applied to high-traffic areas such as driveways and walkways. This textured concrete overlay system can be customized with integral coloring and safeguarded with a pigmented sealer. Explore the most popular products for creating a broomed concrete overlay system at 515 Decorative Concrete Supply.
Knockdown
The most sought-after slip-resistant pool deck and patio concrete finish is the knockdown or spray deck concrete overlay system. This system comprises a self-bonding cement-based overlay with a medium-sized aggregate. Combining color, it is skillfully sprayed onto the concrete surface and then meticulously smoothed with a trowel. At 515 Decorative Concrete Supply, we proudly offer an array of top-rated products crucial for creating this exceptional system.
Micro Cement
The most popular seamless decorative concrete finish for contemporary residential and commercial interiors is the micro cement concrete overlay system. This system consists of an ultra-thin, polymer-modified cement-based overlay that is troweled over properly prepared surfaces to create a smooth, grout-free finish. It delivers a modern, minimalist aesthetic while offering a range of finishes from subtly textured to polished surfaces. Micro cement is an ideal choice for Contemporary Coastal, Tuscan, Modern European, and Mediterranean-inspired designs, bringing timeless character to floors, walls, countertops, and other architectural surfaces.

What is a concrete overlay?
A concrete overlay is a cementitious resurfacing system applied over existing concrete to restore, repair, or enhance its appearance. Overlays can create decorative finishes that mimic natural stone, wood, slate, tile, or textured concrete while improving durability and extending the life of the slab.
What CSP is needed for exterior concrete overlays?
Most exterior concrete overlays require a Concrete Surface Profile (CSP) between 3 and 5, depending on the overlay manufacturer and system thickness. Mechanical preparation using a diamond grinder or shot blaster is typically recommended to remove contaminants, open the concrete pores, and create a proper bonding profile. Always follow the manufacturer's specifications for the overlay being installed.
How should surface preparation be evaluated before installing a concrete overlay?
Before installing any concrete overlay, contractors should inspect the slab for structural integrity, contamination, moisture issues, previous coatings, cracks, and surface soundness. Hollow or delaminated concrete should be removed and repaired before resurfacing. Proper mechanical preparation is essential to ensure long-term adhesion and prevent overlay failure.

What concrete overlay textures are best for interior applications?
Interior concrete overlays offer a wide range of decorative finishes depending on the design goals.
- Wood plank textures create the appearance of hardwood flooring with the durability of concrete.
- Stone textures replicate natural slate, flagstone, or travertine.
- Knockdown finishes provide a modern, slip-resistant decorative surface.
- Micro cement finishes create smooth, contemporary floors ideal for residential and commercial interiors.
The best choice depends on traffic, maintenance expectations, and the desired aesthetic. For a full display of concrete overlay mix designs, click here.
Is there a concrete overlay that can restore driveways and sidewalks?
Yes. Concrete overlays are commonly used to restore aging driveways, sidewalks, patios, pool decks, and other exterior slabs that are structurally sound. Resurfacing can cover minor surface imperfections while providing a new decorative finish without the cost of full concrete replacement.
What is the difference between micro cement and a traditional concrete overlay?
Micro cement is an ultra-thin decorative coating, typically applied in layers of 1–3 mm, that creates a smooth, seamless finish for walls and floors. Traditional concrete overlays are generally thicker and designed for resurfacing larger surface defects while allowing stamped, broomed, knockdown, or textured decorative finishes. Traditional overlays are often better suited for exterior environments and heavier traffic conditions.
Can concrete overlays be applied over cracked concrete?
Yes, but only if the cracks have been properly evaluated and repaired. Cosmetic overlays should never be used to hide structural movement. Active cracks should be stabilized using appropriate repair materials before resurfacing. Reflective cracking can occur if underlying movement is not addressed.
How long does a concrete overlay last?
When installed over properly prepared concrete and maintained correctly, a high-quality concrete overlay can last 10–20 years or more. Longevity depends on surface preparation, product selection, traffic conditions, climate, and ongoing maintenance.
Can concrete overlays be colored or stained?
Yes. Most decorative concrete overlays can be integrally colored, stained, dyed, or enhanced with decorative pigments. Contractors can create finishes that resemble natural stone, weathered wood, tile, or custom architectural concrete while offering nearly unlimited color combinations.
What is the best concrete overlay for pool decks and patios?
For outdoor living spaces, textured overlays such as knockdown, broomed, stone, and sand broadcast finishes are popular because they provide improved slip resistance while creating attractive decorative surfaces. UV-stable sealers and proper maintenance help maximize long-term performance.
What is the difference between a concrete overlay and epoxy?
Concrete overlays are cement-based systems designed to restore and decorate existing concrete while adding texture and architectural finishes. Epoxy flooring systems are resin-based coatings primarily used for chemical resistance, abrasion resistance, and seamless protection in garages, warehouses, commercial spaces, and industrial facilities. The right choice depends on whether the project prioritizes decorative concrete resurfacing or high-performance protective flooring.
Are concrete overlays slippery?
Not necessarily. Decorative concrete overlays can incorporate textured finishes such as knockdown, broom, stone, or sand broadcast surfaces to improve traction. Slip resistance can also be enhanced by adding traction additives to protective sealers.
