In modern residential and commercial construction, floor preparation and coating application require specialized trade expertise. Flooring scopes—spanning structural slab profiling, moisture mitigation, self-leveling underlayments, resinous coatings, and concrete polishing—are critical-path milestones. Delays or substrate failures directly impact downstream finishing trades, project schedules, and overall site profitability.
At AK Level & Polish, we serve as a dedicated single-source flooring subcontractor for General Contractors, custom home builders, commercial managers, and developer-builders across Toronto and the Greater Toronto Area (GTA). We deliver turnkey concrete preparation, leveling, and high-performance coating solutions engineered to satisfy rigorous architectural specifications and demanding delivery schedules.
Core Trade Capabilities & Subcontracting Scopes
We manage complete Division 3 (Concrete) and Division 9 (Finishes) sub-scopes utilizing specialized industrial machinery, trained field crews, and experienced project management.
1. Mechanical Concrete Surface Preparation (CSP 1–5)
Proper mechanical profiling is essential for long-term coating adhesion and slab integrity:
- Planetary Diamond Grinding: Heavy-duty grinding to strip legacy mastics, adhesives, curing compounds, and surface laitance while establishing a uniform profile for thin-film or high-build systems.
- Enclosed Shot Blasting: Steel shot blasting to achieve ICRI Concrete Surface Profiles (CSP) 3 through 5, essential for heavy-duty urethane mortars and thick self-leveling overlays.
- Glue, Epoxy, and Coating Stripping: Specialized PCD (polycrystalline diamond) tooling to remove fail-prone tile adhesives, elastomeric membranes, and degraded floor paint.
2. Hydraulic Self-Leveling Underlayments (SLU) & Slab Remediation
Uneven or damaged concrete slabs delay the installation of finish flooring (LVT, hardwood, tile) and create structural deficiencies. Our high-output pumping equipment handles high-volume leveling:
- Tolerance Restoration: Achieving specified FF/FL (Floor Flatness/Floor Levelness) ratings for commercial logistics centers, retail developments, and residential high-rises.
- Fast-Drying Underlayments: Rapid-setting hydraulic cements allowing foot traffic in 2–4 hours and moisture-sensitive flooring installation within 16–24 hours.
- Deep-Fill Ramping & Pitching: Restoring severely pitted slabs or creating gradual transitions and drain slopes from 1/8″ to 3″+ in a single lift.
3. Industrial & Commercial Resinous Coating Systems
We supply and install fluid-applied resinous flooring systems specified for distinct operational environments:
- Urethane Cement / Mortar: 3/16″ to 3/8″ heavy-duty thermal-shock systems designed for commercial kitchens, food processing bays, and heavy washdown zones.
- 100% Solids Industrial Epoxy: High-build protective coatings engineered for manufacturing facilities, warehousing, mechanical rooms, and auto dealerships.
- Polyaspartic & Rapid-Cure Systems: UV-stable, fast-curing coatings designed for rapid turnaround in retail spaces, residential garages, and high-traffic corridors.
- Decorative Flake & Metallic Epoxy: Custom aesthetic designs for commercial lobbies, multi-family amenities, showrooms, and luxury residential interiors.
4. Architectural Concrete Polishing
For projects specifying exposed, low-maintenance concrete surfaces:
- Multi-stage mechanical polishing ranging from honed satin (200–400 grit) to high-gloss mirror finishes (1500–3000 grit).
- Application of penetrating lithium silicate densifiers and stain-resistant protective guards to maximize surface hardness and abrasion resistance.

Key Operational Advantages for Contractors
Schedule Protection & Trade Coordination
Our teams operate with industrial-grade machinery (high-CFM HEPA dust extractors, heavy planetary grinders, high-output continuous pumps) and offer flexible scheduling—including night or weekend shifts—to prevent critical-path delays and protect milestone timelines.
Technical & Specification Compliance
We work strictly within project submittals, architectural specifications, and relevant ASTM standards:
- Sub-Slab Moisture Vapor Mitigation: In-situ Relative Humidity (RH) probe testing (ASTM F2170) and application of 100% solids epoxy moisture mitigation barriers (ASTM F3010) when slab MVER exceeds manufacturer tolerances.
- Silica Control & Site Safety: Full compliance with Ontario Occupational Health and Safety Act (OHSA) regulations, utilizing closed-loop HEPA dust extraction across all grinding and preparation operations.
- Complete Technical Submittals: Rapid delivery of technical data sheets, Safety Data Sheets (SDS), system mockups, and material certifications for fast architectural sign-off.
