Overview:

Sika SikaMix Frostproofer and Hardener 5 Litre (878091) is a dual-action liquid admixture that speeds up setting and hardening while improving protection against frost damage during cold weather work. Designed for use in mortar, render, screeds and non-structural concrete, it helps keep jobs moving when temperatures drop by reducing delays caused by slow set.

The clear, chloride-free formulation is suitable for use where steel reinforcement is present and provides frost protection in wet mortar down to -8°C when used at the correct dosage. Supplied in a practical 5L container for site work and regular winter use.

Key Features

• Provides frost protection in wet mortar down to -8°C (when dosed correctly)

• Suitable for mortar, renders and screeds, plus non-structural concrete

• Chloride-free formulation (safe to use where steel reinforcement is present)

• Helps improve productivity in cold weather by reducing waiting time

• Clear liquid for straightforward measuring and mixing

• Useful for winter bricklaying/pointing and cold-weather patch repairs

• Can be used as a rapid plugging aid when mixed neat with cement (where appropriate)

How to Use

• Plan the job for cold weather working: use sound materials and good practice for winter conditions.

• Measure the required amount of Sika SikaMix Frostproofer & Hardener based on temperature and cement content:

  • -4°C protection: 2.5L per 50kg cement

  • -8°C protection: 5L per 50kg cement

• Add the admixture to the gauging/mixing water and mix thoroughly for even dispersion.

• Do not exceed the recommended dosage and do not mix with other additives in the same gauging water unless manufacturer guidance confirms compatibility.

• Place and finish as normal, then protect fresh work from severe exposure and follow correct curing/protection methods.
