A grind and seal is a single-coat or double-coat aliphatic polyaspartic floor applied to diamond-ground concrete. Right for sound Calgary slabs that need UV stability and cold-climate performance. On moisture-heavy slabs, an MVB primer goes under the polyaspartic to extend the system to concrete that would not otherwise qualify.

Why Grind and Seal
HDI and IPDI chemistry. No benzene rings, no yellowing, no chalking. Rated SSPC Level 3A at 2,000 hours of UV testing.
One coat for qualifying slabs. Two coats when Flake, metallic, or added film build is the right call. We match the system to your concrete.
Reliable application down to minus 29 Celsius substrate temperature. No seasonal shutdown from October through April.
Elongation at break 50 to 300 percent, roughly 10 to 60 times epoxy. Bridges hairline cracks and handles Calgary freeze-thaw cycles.
Moisture readings, hardness, porosity, contamination. We test before we recommend. If your slab does not qualify, we say so.
Resists automotive fluids, solvents, and household chemicals. Shore D hardness 75 to 80 with full-film aliphatic protection.
A grind and seal is a legitimate, high-performance floor when matched to the right slab. Epoxy Floors Canada is an XPS Certified Installer. We diamond-grind the concrete to a CSP 2-3 profile, vacuum and degrease, then apply aliphatic polyaspartic directly to bare concrete. No filler layers your slab does not need, no coats padding the invoice. Just the right system for concrete that qualifies, engineered for up to 15 years of performance when the slab is sound.
The qualifier is slab condition. Moisture readings, porosity, hardness, contamination, and concrete age all matter. Our quote starts with a slab assessment. If the concrete qualifies as-is, grind and seal is the engineered answer. On moisture-heavy slabs, an MVB primer goes down first to lock the moisture under the system. For soft, contaminated, or compromised concrete, a full epoxy and polyaspartic build is the right call. The assessment determines the build.
Polyaspartic is aliphatic polyurea. The isocyanates we use (HDI and IPDI) contain no benzene rings in their molecular backbone. UV photons cannot break bonds that are not there. Epoxy ambers and yellows within months of sun exposure at the molecular level. Polyaspartic is immune at the molecular level. In a full multi-coat system, the polyaspartic topcoat protects an epoxy base that will still amber underneath. In a grind and seal, the entire film is aliphatic from substrate to surface.
A grind and seal on its own is not a moisture-mitigating system. On Calgary slabs with elevated moisture readings, we add an MVB (moisture vapor barrier) primer under the polyaspartic. This extends grind and seal to concrete that would otherwise fail, and protects the coating from hydrostatic pressure through the slab. For soft or powdery concrete, oil-saturated slabs, old coatings that release, or surface correction needs, we install the complete system: a full epoxy base, decorative media if desired, and polyaspartic topcoats. We test every slab, show you the results, and recommend the build that actually works for your concrete.

HOW IT'S DONE
Slab condition check: hardness, porosity, contamination, and moisture readings. If the concrete does not qualify for grind and seal, we say so before we quote. No surprises on install day.
Werkmaster Raptor XT planetary grinder profiles the concrete to CSP 2-3. Bartell HD1 HEPA dust extraction keeps the space clean from first cut to final pass.
Vacuum, then acetone or xylene wipe. Zero residual dust. Substrate prepared to bond at full strength.
Mixed to spec, ribboned and back-rolled for even film build. Single coat for qualifying slabs, double coat for Flake or metallic.
Solid colour or clear seal work as a single coat on qualifying slabs. Flake and metallic broadcasts require a double-coat build with a clear lock-in topcoat.
Solid colour polyaspartic matches any RAL or custom paint code on request.
