Sikamix Plus Mortar Plasticiser - 25L

Yes, its chloride-free formula specifically ensures that it will not cause corrosion to steel reinforcement bars or wall ties.

Yes, it is suitable for both internal and external renders, providing improved adhesion and reduced cracking.

It does not significantly alter the final set time when used at the recommended dosage, though it does improve the 'open' time for working.

Keep the product in a cool, frost-free environment between 5°C and 25°C.

Always dilute the product into your mixing water first for the most uniform distribution.

Sikamix Plus is designed for standard cement-based mortars; consult the manufacturer or a technical datasheet before using with specialized lime products.

You may have exceeded the recommended dosage; reduce the amount of plasticiser in your next mix and double-check your water-to-cement ratio.

Ensure the plasticiser is thoroughly mixed into the water before adding the dry components to ensure even distribution throughout the batch.

Check your sand grading and water content; ensure you are not using too much water and that the mortar is allowed to cure properly away from extreme drying winds.
