FAQs

Is Sikamix Plus safe to use with steel reinforcements?

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

Can I use this for internal rendering?

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

Does this product affect the drying time of mortar?

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

What is the recommended storage temperature?

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

Do I add it to the dry mix or the water?

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

Is this product suitable for use with lime-based mortars?

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

Troubleshooting

Mortar feels too soft or runny

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

Difficulty achieving a consistent mix

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

Cracking after curing

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.

Pros and Cons

Pros

Significantly improves mortar spreadability
Prevents corrosion of internal steel reinforcement
Reduces shrinkage and cracking during drying
Enhances overall bond strength and durability
Professional grade quality for consistent results

Cons

Requires precise measurement for optimal performance
Large 25L container may be heavy to handle
Over-dosing can potentially affect final set times

Setup, Compatibility & Care

For optimal results, add the required amount of Sikamix Plus to the mixing water before adding it to the dry mortar mix. Always refer to the specific dosage recommendations on the product label, as ratios may vary depending on the sand type and cement grade. Store the 25L container in a cool, frost-free location and ensure the cap is tightly sealed after every use to prevent evaporation or contamination. This product is compatible with most standard Portland cements. Avoid mixing with other admixtures unless directed by the manufacturer, as chemical interactions could impair performance.
