AC 309 – Water-Based Chemical Curing Agent
AC 309 is a water-based chemical curing agent, specially developed for application on floors, slabs, pavements, and precast fresh concrete in outdoor environments (uncovered areas). It offers high coverage efficiency, providing the best cost-benefit ratio on the market, along with excellent surface protection and no floor pathologies.
Function:
Delays water loss from fresh concrete, improving cement hydration. Enhances concrete surface strength. Prevents plastic and hydraulic shrinkage cracks. Forms a protective film over the surface, shielding it from dirt during the concrete curing process.
Advantages:
Prevents cracks in concrete Increases strength and durability Eliminates the need for traditional wet curing Protects the surface from stains and dust Reduces dust generation Facilitates cleaning Low VOC emission
Applications:
External concrete floors, pavements, and slabs Concrete compression layers Garage and parking lot floors in outdoor areas General precast concrete elements
How to Use:
Apply immediately after pouring and finishing the concrete. Use a backpack sprayer with a conical nozzle. Apply a single coat, avoiding overlap and excess product. Coverage: 8 to 10 m²/liter. Drying time: 30 to 90 minutes.
Coverage:
8 m²/liter on broom-finished external floors 10 m²/liter on troweled external floors
