Sika 3 in 1 Rendamix Plasticiser Retarder Waterproofer for screeds and for renders in a 5 Litre tub a liquid admixture that enhances cementitious render applications by combining water resistance, plasticising properties, and retarding capabilities for both external and internal rendering tasks.

Who This Product Is For

This product is designed for construction professionals and home improvers working with cementitious render mixes. It suits those undertaking rendering work on buildings where water resistance and workability are important considerations.

It is appropriate for projects involving external wall rendering, internal finishes after damp-proofing, and applications in environments where moisture protection is needed.

Key Features

• 3-in-1 Formula: Combines water-resistance, plasticising, and retarding properties for versatile rendering solutions.
• Improved Workability: Makes render mixes easier to apply and manage over larger areas.
• Efflorescence Inhibitor: Reduces the appearance of unsightly white deposits on rendered surfaces.
• Water Resistance: Provides improved protection against water ingress, helping create a longer-lasting finish.
• Reduced Water Bleed: Limits surface water bleed during application, creating a more consistent mix.
• Low-Toxicity Composition: Safe to handle while maintaining high-performance standards.

Key Benefits

• Improves rendering efficiency by allowing greater coverage in a single application.
• Reduces the risk of water damage to external and internal surfaces.
• Minimises surface absorption, improving the durability of the final finish.
• Acts as a practical solution for professional and DIY rendering projects.

Practical Applications

Feb Rendamix is suitable for:

• External rendering on walls using techniques such as dashing, harling, and roughcasting.
• Internal applications following the installation of damp-proof courses.
• Creating water-resistant finishes for above-ground structures.
• Enhancing the durability of cementitious render in high-moisture environments.

How This Fits Into a Typical Job

This admixture is used during the mixing stage of rendering work. It is added to the mixing water before combining with sand and cement to create the render mix. The product functions throughout the application and curing process, improving workability during application while providing water-resistant properties that protect the finished surface.

It forms part of a complete rendering system where surface preparation is completed first, followed by mixing with the admixture, application of the render, and proper curing to achieve the desired finish.

How to Use

1. Surface Preparation:
   • Check the substrate is clean, sound, and free from contaminants, with any existing coatings removed. For porous surfaces, applying a bonding slurry can improve adhesion.
2. Mixing:
   • Add Feb Rendamix to the mixing water at a ratio of 1 part product to 20-40 parts water. Use 500-1000 ml of the product for every 50 kg of cement.
3. Application:
   • Mix thoroughly with sand and cement to achieve a uniform consistency, avoiding overmixing. Apply the render wet-on-wet to maximise bond strength.
4. Curing:
   • Allow the render to cure according to standard practices, and take sufficient drying time before applying additional coats or finishes.
