Bond-It Frostproofer & Rapid Hardener - 5 Litre

Bond-It Frostproofer & Rapid Hardener – 5 Litre is a reliable cold weather additive for cement-based mixes, specially designed to improve performance during low or sub-zero temperatures. This high-strength chemical speeds up the hydration process, allowing mortar and concrete to set faster and gain strength more quickly, even in frosty conditions.

Perfect for all-year-round bricklaying and rendering, especially in winter months, this frostproofer not only boosts early strength gain but also improves workability and water resistance. The result is a denser, more durable mortar with reduced shrinkage and curing time, helping minimise the risk of frost-related cracking.

Thanks to its chloride-free formulation, it's safe to use with steel reinforcements, wall ties and structural components, offering peace of mind on every job. Whether you're working on external walls, garden structures or winter construction projects, this additive helps your mortar cope with the cold and keeps your build on track.
