Bostik Cementone Wintaplas Chloride Free Frostproofer & Plasticiser - 5L

Its main purpose is to provide frost protection and accelerate the setting of mortar mixes in cold weather, while also improving workability and the strength of the cured concrete.

Yes, this product is chloride-free, making it safe for use in applications involving embedded metal components and steel reinforcement, as it eliminates the risk of corrosion.

Refer to the product's technical data sheet or the instructions on the packaging for the recommended dosage. Dosage is typically based on the weight of cement or per batch of mortar, and may vary slightly depending on conditions.

While it can be used, its primary benefits are for cold weather conditions. In warm weather, its accelerating properties might not be needed and could potentially lead to a too-fast set if not managed correctly.

It is suitable for bricklaying, rendering, and blockwork applications where cold weather performance is required.

The product is orange in colour.

The container size is 5 litres.

Ensure the correct dosage of Wintaplas was used and thoroughly mixed into the gauging water. Verify that ambient temperatures are within the product's effective range and that no other admixtures are interfering with the setting process.

Check that the correct amount of Wintaplas was added. Excessive amounts can lead to overly plastic mixes. Adjust aggregate and water content slightly if necessary, adhering to standard mortar mix ratios.

While Wintaplas is chloride-free, ensure other components in the mix (e.g., aggregates, water source) do not contain chlorides. Proper concrete cover over reinforcement is always essential for corrosion protection.

If the product has been exposed to freezing temperatures, it may be compromised. Allow it to return to ambient temperature and visually inspect for any separation or thickening. If the product appears normal, test a small batch before full application. If significantly altered, it may need to be replaced.
