SikaMix Plus Mortar Admix Plasticiser is a 5 litre admixture formulated to enhance the performance of mortars, renders, and plasters by improving workability, reducing segregation, and providing freeze-thaw resistance for durable results in both indoor and outdoor applications. It replaces lime in traditional mixes, saving time and effort during preparation.

Who This Product Is For

This product is designed for construction professionals, including bricklayers, plasterers, and builders, as well as serious DIY users undertaking masonry work. It suits those working on brickwork, rendering, or pointing projects where consistent mortar performance is required.

Key Features

• Advanced Plasticising Action: Enhances the hydration process for smoother, more workable mortar.
• Freeze-Thaw Resistance: Protects against frost damage and improves durability in cold weather.
• Efflorescence Reduction: Minimises surface discolouration for a clean finish.
• Chloride-Free Composition: Safe for use in various construction applications without compromising structural integrity.

Key Benefits

• Creates an even, cohesive mix that improves trowel-ability and application precision.
• Reduces bleeding and segregation for a stable, consistent mortar.
• Offers lasting protection against weather-related damage, including freezing temperatures.
• Eliminates the need for lime, simplifying the mixing process and reducing potential issues like lime bloom.

Practical Applications

The product is suited for a range of construction tasks, providing dependable results across different environments and requirements.

• Perfect for brickwork and block laying, supporting load-bearing and decorative structures alike.
• Ensures smooth external and internal rendering, delivering professional-quality finishes.
• Suited for pointing and repointing; it provides strong adhesion and improved durability over time. When applying mortar into joints, a mortar and cement pointing gun can speed the job and give neat results.

How This Fits Into a Typical Job

This admixture is used during the mortar preparation stage. It is added to gauging water before mixing with sand and cement, becoming part of the mortar mix that is then applied in bricklaying, rendering, or pointing work. Proper incorporation at this stage ensures the enhanced properties are distributed throughout the mortar.

Specifications

• Pack Size: 5 litres
• Dosage: 125 ml to 250 ml per 50 kg of cement
• Composition: Chloride-free
• Primary Use: Mortar, render, and plaster admixture

Not Suitable For

• Not intended as a general-purpose additive for non-construction materials
• Should not replace washing-up liquid or other non-specialist plasticisers
• Not for use without proper mixing equipment and adherence to dosage guidelines
• Not recommended for applications outside of mortar, render, or plaster work

How to Use

1. Prepare the Materials: Add the product to gauging water at the recommended dosage before mixing with sand and cement. Avoid using washing-up liquid as a substitute plasticiser, as this compromises structural strength.
2. Mixing: Use 125 ml to 250 ml per 50 kg of cement, adjusting for the desired degree of plasticity. Mix thoroughly to achieve a uniform consistency using a suitable power mixer.
3. Application: Use the prepared mix immediately for best results. Apply to the intended surface with the appropriate tools for bricklaying, rendering, or pointing tasks.
4. Curing: During the initial curing phase, allow the mortar to set and cure under suitable conditions, avoiding exposure to extreme weather.

Storage and Maintenance Tips

• Store the product in a cool, dry place to maintain its effectiveness over time.
• Keep the container tightly sealed when not in use to prevent contamination.
