Sika Wintermix Green 5L – Professional Grade Cold Weather Cement Admixture

Overview:
Sika Wintermix Green 5L is a premium, ready-to-use, chloride-free admixture specially formulated to accelerate the setting time and early strength development of cement-based mixes during cold weather conditions. Designed with performance, safety, and environmental responsibility in mind, Sika Wintermix Green is ideal for use in concrete, mortar, and render applications, particularly when ambient temperatures threaten to delay curing processes.

Key Features and Benefits

• Cold Weather Performance: Enables workability and curing of cementitious mixes in low-temperature environments (typically between +4°C and +15°C).

• Chloride-Free: Non-corrosive to steel reinforcement, making it safe for use in reinforced concrete structures.

• Accelerated Setting: Reduces the initial and final setting time of cement mixes, enhancing productivity and reducing downtime in colder months.

• Enhanced Early Strength: Promotes early strength gain for improved resistance to frost damage.

• Convenient and Ready-to-Use: Simple to dose and mix on-site with no additional dilution required.

• Eco-Friendly Formula: Formulated with environmentally conscious materials and packaged in recyclable containers.
