Patched, worn or discoloured concrete slabs get a second life under a thin polymer overlay. We prep the substrate, apply the topping in controlled lifts, then finish it with polish, stain or sealer. No slab replacement needed. Every project includes a free written estimate and firm completion date.
A concrete slab that has surface damage, patches, stains or inconsistency cannot take a direct polish or stain. Tearing it out and pouring new concrete is expensive and disruptive. A micro-topping solves the problem by creating a fresh, sound surface on top of the existing slab.
The overlay is a polymer-modified cement applied in thin layers, each one bonding tightly to the substrate below. The result is a smooth, seamless base ready for polished concrete, acid or water stain, or a protective sealer. The slab underneath stays in place.
Micro-topping is not the answer when the slab itself is failing. Deep cracks that move, heaving, base erosion, or structural settlement require a tear-out and new pour. We walk the slab, assess the damage, and tell you whether it is a cosmetic fix or a structural replacement.

Installation sequence
How Micro-Topping Installation Happens in Oshawa
Slab inspection and substrate prep
We examine the existing concrete for structural soundness, identify any cracks or repairs needed, test for moisture, and confirm what finish will go on top of the topping.
Mechanical profiling and priming
The slab surface is ground or shot-blasted to open the pores and create mechanical bond. Any necessary repairs are made, then the manufacturer-specified primer is applied to the entire substrate.
Topping application in lifts
The polymer-modified topping is trowelled on in thin, controlled passes. Each lift is feathered and blended to the previous one, building a uniform thickness with no voids or thin spots.
Finishing, curing and handoff
The surface is burnished to the desired sheen, allowed to cure per schedule, then the final finish (polish, stain or sealer) is applied. The floor is ready for use on the agreed date.
Finish layer options
Choosing a Finish Above the Topping
The micro-topping is the base layer. The finish is what you see and walk on. Most homeowners choose polished concrete for a bright, hard-wearing surface that shows the topping's uniform colour and texture.
Others prefer stained concrete for warmth and depth, layering acid or water-based stain over the topping before sealing. A clear sealer alone gives a satin, natural look. The topping accepts all three finishes equally well and pairs seamlessly with radiant floor heating if you want warmth built into the slab.
Thickness, finishes, structural limits and what to expect during installation.
A few millimetres total, applied in lifts. It is not a full overlay; it is a thin resurfacing that bonds to the substrate and gives the next finish a clean canvas.
When the slab has structural problems, heaving, deep cracks that move, base failure. The topping fixes a cosmetic-grade slab problem, not a structural one. We assess the slab and tell you straight which side of the line it is on.
Any of the interior finishes we install, polish, stain, or a clear sealer. The topping is engineered to take them all.
Done properly, no. The lifts blend together and the burnish produces a uniform surface. We pre-test on a sample area for tricky finishes to confirm the look before doing the whole floor.
Yes. Heated floor underlayment goes down first to encase the radiant heat tubing, then the micro-topping over it, then the finish above. The whole stack works as one heated floor system.

What Oshawa Homeowners Say About Their Micro-Topping Floors
Old basement slab was patched and ugly. They micro-topped it then polished, and now it reads as a brand-new floor without the tear-out and mess of a replacement.

Saved us a slab replacement on the main floor. Micro-topping plus stain plus seal gave us exactly the look we wanted, and the existing slab is hidden underneath.

Knew the answer when they walked in, micro-topping was the move because of how patched our slab was. Done in less than a week and the new floor looks seamless.

★★★★★
Combined with heated floor underlayment underneath. The radiant heat warms the topping evenly and the finished floor is exactly the same look top to bottom.
