R Cure Formula Densifier

Product remains optically clear with zero visual profile post-cure. No topical sheen, film deposition, or surface residue. Chemical reaction occurs within pore matrix; densification is entirely subsurface. Suitable for applications requiring unaltered aesthetic appearance.

Light pedestrian traffic permissible after 4–6 hours surface-dry condition. Full-cure strength development and mechanical loading capacity achieved at 24 hours, per ISO 1920 curing protocol. Recommended minimum 48-hour cure interval before motorized vehicle operation or heavy equipment placement.

Application feasible on concrete ≥24–48 hours post-placement, following initial set and surface hardening. Verify compressive strength development (minimum 5–7 MPa) before application. Green concrete with high free water content may exhibit reduced penetration efficiency; allowsurface drying prior to treatment.

Ready-to-Use (RTU) formulation requires zero pre-treatment; direct spray or roller application at manufacturer’s optimized silicate concentration. Concentrate variant diluted 1:3 (v/v) with potable water prior to application. Concentrate provides economic advantage for large-area projects (>500 m²) and permits on-site formulation flexibility per site-specific porosity assessment.

Substrate compatible with epoxy, polyurethane, acrylic, and polyaspartic coating systems when cure window extended to minimum 48–72 hours post-application. Fully densified surface provides superior mechanical adhesion profile. Mandatory: conduct ASTM D3359 adhesion pull-test on representative site sample prior to full-system specification.

Single-coat application achieves primary densification on concrete with normal porosity (water absorption 10 years), high water-cement ratio mixes (w/c >0.60), or weathered surfaces exhibiting elevated capillary porosity. Apply second coat minimum 24 hours post-initial cure.

Substrate must achieve ISO 8501-1 Sa 2.5 cleanliness minimum; remove oil, grease, curing compounds, laitance, and atmospheric contamination. Mechanical abrasion—grit blasting (Sa 2.5), grinding (80–120 grit), or shot peening—is normative to expose capillary structure and optimize penetration depth. Surface must be dry (≤4% moisture content) at time of application.

Effective on established concrete substrates when subjected to comprehensive surface preparation per ISO 8501. Recommend abrasive preparation (Sa 2.5) and rigorous alkalinity verification (pH >12) to confirm reactive capacity. Aged concrete with sealed or densified prior treatments requires assessment of existing membrane integrity; prefer mechanical removal if present.

VOC content <50 g/L (ASTM D3960) qualifies as low-VOC formulation for enclosed-space application. Water-based composition (non-flammable per ASTM D3278); storage stable at 5–40 °C. Ensure mechanical or natural ventilation (minimum 6 air changes/hour) during application and cure phases. Product poses no acute health hazard; standard occupational hygiene practices recommended.

Silicate densification represents irreversible, chemically-bonded hardening—not a topical or removable coating. Once reactive silicates combine with free calcium hydroxide (Ca(OH)₂) to form C-S-H gel, densification persists indefinitely without degradation under normal service conditions. No reapplication protocol required; performance is permanent.
