When specifying or installing a decorative quartz flooring system for demanding commercial, industrial, or upscale residential spaces across the Greater Toronto Area, the choice of binding resin is just as critical as the quartz aggregate itself. At AK Level & Polish Inc., we engineer advanced commercial flooring and industrial flooring systems utilizing high-performance quartz flooring epoxy and companion polymer matrices.
Below is an engineering overview of how epoxy resins integrate with ceramic-coated quartz to create an impenetrable, industrial-strength floorplate.
1. The Role of Epoxy in a Quartz Flooring System
A decorative quartz floor is not a standalone paint or thin coating; it is an engineered composite matrix. Epoxy serves as the structural backbone of this system across multiple application stages:
- Moisture-Mitigating Primers: High-solids epoxy primers penetrate deep into the open pores of mechanically prepared concrete, sealing the substrate and blocking hydrostatic vapor drive to prevent osmotic blistering and delamination.
- Base Coat Matrix: Applied at a controlled uniform film thickness, the pigmented epoxy base coat provides the foundational adhesive bond and establishes the background color tone that locks in beneath the quartz broadcast.
- Full-Broadcast Saturation (100% Rejection): While the base epoxy is wet, graded, kiln-dried quartz aggregates are broadcast to total saturation. The aggregate sinks into the epoxy layer until the resin matrix is completely full, creating an exceptionally dense, impact-resistant structural wear layer.
2. Core Technical Performance Characteristics
When formulated as a 100% solids formulation (free of shrinking solvents and volatile organic compounds), quartz flooring epoxy delivers certified physical properties tested against strict ASTM standards:
- Compressive Strength: Combined with broadcast quartz, the system achieves a compressive strength ranging from 12,500 to 17,500 psi (ASTM D-695 / C-579), ensuring the floor will not crush or deform under heavy rolling loads, pallet jacks, or industrial equipment.
- Bond Strength to Concrete: Exceeds 400Â psi with 100% concrete substrate failure (ASTM D-4541 / D-7234), proving that the bond is structurally stronger than the concrete slab itself.
- Impermeable Water Absorption: Exhibits a water absorption rate of <0.04% (ASTM D-570), creating a completely seamless, non-porous barrier that locks out moisture, harsh cleaning chemicals, road salts, and organic acids.
- Hardness: Achieves a Shore D hardness of 75 to 80 (ASTM D-2240), providing high resistance to surface indentation and continuous physical wear.
3. Surface Preparation: The Prerequisite for Epoxy Adhesion
Epoxy resins require meticulous mechanical surface preparation to achieve their maximum structural bond. Chemical washing or acid etching is never sufficient for industrial resinous systems.
- Concrete Surface Preparation: Technicians utilize heavy-duty industrial diamond grinders or shot-blasters to strip away old sealers, eliminate weak surface laitance, and open concrete pores.
- ICRI Profile Achievement: This mechanical process establishes an International Concrete Repair Institute (ICRI) profile of CSP 3 to CSP 5, creating the microscopic peaks and valleys required for permanent epoxy interlocking.
- Subfloor Moisture Testing: Prior to primer application, in-situ relative humidity testing per ASTM F-2170 confirms that moisture vapor emission rates are within safe limits.
4. Protective Topcoating: Sealing the Epoxy Matrix
While epoxy provides unmatched structural strength and adhesion, standard epoxies can amber under continuous ultraviolet (UV) light exposure. To ensure long-term clarity, chemical resistance, and slip performance, quartz epoxy systems are encapsulated with specialized topcoats:
- Polyaspartic & Urethane Topcoats: One or two high-performance clear topcoats are applied over the scraped quartz matrix. These UV-stable formulations lock in chemical and scratch resistance while allowing customization of surface texture and sheen (from high-gloss to slip-resistant satin or matte).
- Slip Resistance: Topcoats can be engineered to maintain a static coefficient of friction between 0.8 and 0.9 (ASTM D-2047), exceeding ADA compliance standards for safety in wet or high-traffic zones.
