Is This the Right Page?
Where Polymer Cementitious Concrete Overlays Fits
A good fit for
- Spalled, pitted, or sun-damaged driveways, patios, and entries
- Sound slabs that need a new wear surface instead of replacement
- Decorative upgrades — overlays, microtopping, stain, and seal
- Paver and flagstone surfaces due for cleaning and resealing
Not the right system for
- Structurally failing slabs with deep settlement or heaving
- Sites where drainage problems must be corrected first
- Surfaces better served by a film coating alone, like interior garages
System Overview
Polymer & Cementitious Concrete Overlays
Resurface suitable aging slabs without full demolition when the underlying concrete is sound enough for an overlay.
Cracked, spalled, or uneven concrete driveways and walkways are unsightly safety hazards. Polymer-modified cementitious overlays allow us to resurface aged slabs without the massive expense of demolition and repouring.
We bond a thin, polymer-reinforced concrete layer directly to the existing concrete, texturing it to a knockdown, broom, or stamped finish that reduces surface temperatures under the hot Arizona sun.
Why These Surfaces Fail Without the Right System
Sun and monsoon damage
Arizona UV, heat cycles, and monsoon moisture break down unprotected surfaces, causing spalling, pitting, and fading.
Cheap resurfacing jobs
Thin patch products applied without mechanical prep peel and telegraph old damage back through. A proper overlay system bonds to a prepared slab.
Unaddressed cracks
Cracks that are skimmed over instead of routed and repaired reappear in the new surface. Repair scope is part of every honest resurfacing quote.
Technical Specifications & Features
Our Engineered Installation Process
1. Abrasive Washing & Prep
Pressure washing and mechanical profiling to remove dirt and open the concrete pores.
2. Fracture Stitching
Chasing and filling cracks with high-tensile epoxy and concrete stitching staples to stabilize the concrete base.
3. Polymer Base Coat
Applying a high-bond polymer primer and slurry base coat to lock in the slab and create a uniform layer.
4. Textured Finish & Sealer
Spraying or troweling the decorative knockdown overlay, followed by UV-stable tinted acrylic sealers.
What Drives the Price
Every polymer cementitious concrete overlays quote is built from the same practical inputs — there is no mystery number. Sending photos and approximate square footage gets you an accurate estimate faster.
- Square footage of the surface
- Depth of damage and the repair scope required
- System choice — overlay, microtopping, stain and seal
- Finish, texture, and color selection
- Removal or tear-off of failed previous work
Our 5-step estimate tool collects surface type, size, and condition so pricing reflects your actual slab.

These are planning guidelines, not a substitute for the written proposal. Exact products, schedule, finish, maintenance, and warranty terms depend on the inspected surface and selected system.
Installation & Return to Use
- Installation timing depends on surface condition, repairs, system build, weather, and site access.
- Foot traffic, furniture return, and vehicle traffic are separate milestones and are confirmed for the products used on your project.
- Do not plan return-to-service from a generic one-day claim; the written project schedule controls.
Maintenance
- Remove abrasive dirt and grit routinely so it does not become a wear layer.
- Use cleaning products and methods approved for the installed finish.
- Address damage, failed joints, drainage issues, or chemical spills before they spread.
Colors, Texture & Appearance
- Final color, gloss, texture, and traction are selected for the surface and how it will be used.
- Samples and photographs are useful guides, but lighting, concrete condition, and hand-applied texture can affect the final appearance.
Warranty Expectations
- Coverage depends on the installed system, substrate condition, preparation scope, and written proposal.
- Concrete movement, moisture, abuse, drainage, and normal wear may be treated differently from coating adhesion.
- Review the project-specific warranty and maintenance requirements before approving the work.
