Bostik Cementone Wintaplas Chloride Free Frostproofer & Accelerator 5ltr

Bostik Accelerator & Frostproofer is a specially formulated liquid that accelerates the setting of mortar mixes, making it ideal for use in cold weather, particularly during winter months. This product is designed to improve workability by plasticising the mix, ensuring consistent results in challenging conditions. Whether you're working on bricklaying, rendering, blockwork, or mortars containing embedded metal, Bostik Accelerator & Frostproofer enhances the efficiency and quality of your work.

It is especially suitable for use in colder climates where setting times can be extended. This product is formulated to work with Portland cement (CEM I) and Portland-fly ash cement (CEM II/B-V). It is a chloride-free solution that does not interfere with the integrity of mortar or concrete mixes, making it a safer choice compared to calcium chloride-based accelerators.
