Description
How ASA Curing Compound works (in simple terms)
Fresh concrete needs water to hydrate. ASA R forms a temporary resin film that slows evaporation, so the slab keeps its water long enough to hydrate fully. The result is stronger paste binding the aggregates, fewer early cracks, tighter abrasion-resistant surfaces, and better long-term performance.
Technical data (ASA Curing Compound)
• Base: ASA Curing Compound (Resin), formulated with a resin technology equivalent to those used in Pliolite®-based systems.
• Standards: ASTM C309 Type 1 (clear) / Type 2 (white); Class B (resin-based). AASHTO M148 equivalent classification.
• Abrasion reference: Assessed using ASTM C944 (rotating-cutter method) for abrasion resistance of concrete surfaces.
• Appearance: Clear, opaque liquid.
• Coverage: 6–10 m²/L depending on surface and finish.
• Specific gravity (20 °C): 0.83–0.89.
• Flash point: ~30 °C.
• Shelf life: Up to 24 months when stored per instructions.
• Uses: One-step cure + prime/seal system; useful as a dust-proofer/surface hardener.
• Overcoating compatibility: Cementitious systems, bituminous emulsions, polyurethane, polysulphide, epoxies.
Application guide (step-by-step)
1. Timing: Spray as soon as the sheen of bleed water disappears on fresh concrete. Do not apply if bleed water is still pooling. For formed surfaces, apply immediately after formwork removal.
2. Method: Low-pressure, even spray in a continuous coat; avoid ponding. Target 6–10 m²/L.
3. Second coat (optional): On very open or windy/hot slabs, a cross-coat can improve moisture retention. (Follow site mock-up.)
4. Overcoating: Once cured/dry, most compatible overlays/coatings can proceed per their data sheets and site pull-off tests.
5. Cleanup & safety: Avoid skin/eye contact; wash splashes with water; seek medical help if ingested. Keep away from ignition sources (flash point ~30 °C).
Clear vs. White reflective—when to choose what
Clear (Type 1): General use; shows the finish; ideal indoors and standard temperatures. White reflective (Type 2): High albedo limits heat build-up on sun-exposed slabs, helping retain moisture and reduce thermal stress in hot climates.
FAQs (fast answers)
Is this spec-compliant? Yes, ASTM C309 and AASHTO M148 are the correct standards for ASA Curing Compound classifications used by Departments of Transportations and major builders Does it help abrasion resistance? Proper curing significantly improves surface hardness; abrasion is evaluated to ASTM C944 Will it block future coatings? It’s overcoat able with common systems when surface is prepared per the coating manufacturer. Always test adhesion.
