An Ardex overlay system resurfaces existing concrete with a fraction of the disruption of full slab replacement. Boston Concrete is the Ardex specialist for Boston overlay projects, decorative microtopping for showrooms, structural overlays for repairing worn surfaces, decorative stamped overlays for entries and patios. Every project starts with a free written estimate.
Worn or out-of-spec concrete does not always need replacement. If the underlying slab is structurally sound, an Ardex overlay can resurface it with the look and performance the project requires, at a fraction of the tear-out cost. Ardex offers a full range of overlay systems, microtoppings for decorative refresh, polishable overlays, structural overlays, stamped overlays for hardscape work.
We install Ardex overlays as the Ardex-system specialist, meaning the install follows Ardex protocols for prep, primer, mix, placement and cure. The system warranty depends on installer compliance with those protocols; we deliver to spec.
Same Ardex expertise across our other Ardex services and the broader brand specialty work. Where the slab is too far gone for overlay, we recommend full replacement via the appropriate residential or commercial service.

How it works
How We Install Ardex Overlays in Boston
Assess existing slab
We assess the existing slab for structural soundness, surface condition, moisture content, and the overlay system that fits, decorative thin-set vs structural overlay vs stamped system.
Prep to Ardex spec
The slab is diamond-ground to the Ardex prep profile, contaminants removed, cracks repaired with compatible material, and the surface primed with the Ardex primer for the chosen overlay.
Mix and pour overlay
The Ardex overlay material is mixed to manufacturer ratios, placed at the engineered thickness, and finished to the chosen look (troweled, stamped, polished as appropriate).
Cure and seal
The overlay cures per Ardex schedule, gets the matched topcoat or sealer per system spec, and is handed off ready for use with the warranty documentation and maintenance protocol.
Why specialist install
Ardex Spec Compliance Is the Whole Job
Ardex systems work as designed when installed to Ardex spec. Substituting primer, mixing off-ratio, skipping prep, or applying outside the working window all void the system warranty and risk early failure. We follow the spec because that is what makes the system perform.
Coordinate with adjacent Ardex self-leveling if the slab needs flatness correction before overlay, and with our Ardex repair mortars for spalled areas that need addressing before resurfacing.
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.
