Existing concrete that's sound underneath but tired on top gets new life through an Ardex overlay. No tear-out, no months of disruption. Laval Concrete applies Ardex microtoppings, structural overlays, and stamped finishes to residential and commercial slabs across Laval. Call for a free written estimate.
Ardex Overlay Systems: Resurfacing Without Replacement
A concrete slab that has lost its finish or developed surface wear does not automatically need to be torn out and replaced. If the slab structure is intact, an Ardex overlay system can restore appearance and function at a fraction of the cost and disruption of full replacement. Ardex manufactures overlays for every scenario: thin decorative microtoppings for showrooms and entries, polishable overlays for retail floors, stamped overlays for patios and hardscape, and structural overlays for heavy-use areas.
Installation quality determines whether the overlay performs as designed. Ardex systems depend on precise prep, correct primer selection, proper mix ratios, and controlled cure conditions. We follow Ardex specifications exactly because that is what activates the system warranty and ensures long-term durability.
We inspect the slab for structural integrity, surface condition, moisture levels, and any cracks or spalls. This assessment determines which Ardex overlay system fits the job and what prep work is required.
Grind and prepare per spec
The slab surface is diamond-ground to the Ardex profile, contaminants removed, cracks filled with compatible repair material, and the surface primed with the specified Ardex primer for the chosen overlay system.
Mix, place, and finish overlay
Ardex overlay material is mixed to exact manufacturer ratios, placed at the engineered thickness, and finished to the specified look: smooth trowel, polished, or stamped as the project calls for.
Cure and seal per schedule
The overlay cures on the Ardex timeline, receives the matched topcoat or sealer per system specification, and is handed off with warranty documentation and care instructions.
Specification compliance
Ardex Warranty Depends on Installer Adherence to Spec
Ardex systems are engineered products. They perform as designed when every step follows Ardex specification: the right primer, the correct mix ratio, the proper placement technique, the specified cure window. Skipping prep, substituting materials, or rushing cure all compromise the system and void the warranty. We install to spec because that is what makes the overlay last.
Overlay systems, thickness ranges, warranty and when overlay beats replacement.
When the underlying slab is structurally sound and the surface issues are cosmetic or wear-related. Overlay restores the look and performance at a fraction of replacement cost; structural failure of the slab itself requires replacement.
Ranges widely by system, from very thin decorative microtoppings to substantial structural overlays. The overlay thickness matches the existing-slab condition and the use the resurfaced floor will see.
Yes, Ardex offers polishable and stamped overlay systems. The look is part of the system spec; we agree the look up front and use the matched Ardex product for that finish.
Yes. Ardex warranty applies when installers follow Ardex spec on prep, mix, install and cure. We install to spec and deliver the warranty documentation at handoff.
A few days to a week for most residential or small-commercial projects, with cure before service. Larger or staged projects take longer; the full schedule is in the quote.
Microtopping overlay on a tired commercial entry. Looks brand new, no tear-out, Ardex warranty support. Real value for the right scope.

Stamped Ardex overlay on a patio that had been considered for replacement. Three years in, holding perfectly. Cost a fraction of replacement and looks better.

★★★★★
They followed Ardex spec exactly, walked us through the warranty documentation at handoff. Other contractors had quoted overlays without mentioning spec compliance. Real expertise.

Polishable overlay on a worn showroom floor. Polished to spec, looks like the original slab was never compromised. The Ardex system is what made it possible.
