REF: SKREND5 | MPN: 102452 | Barcode: 5055047200529

Sika Rendermix is a liquid admixture that improves water resistance and workability in cement renders and screeds for both internal and external applications.

Who This Product Is For

This product is designed for builders, plasterers, and professional renderers working with cement-based renders and screeds.

It also suits serious DIY renovators undertaking rendering or screeding projects, whether for new construction or renovation work.

Key Features

• Water Resistance: Reduces water ingress, offering long-lasting surface protection.
• Improved Workability: Enhances the consistency of mortar for easier application.
• Air Entraining: Adds microscopic air bubbles to the mix, improving freeze-thaw resistance.
• Multi-Layer Bonding: Allows secure adhesion between layers when applied wet-on-wet.
• Adaptable Dosage: This can be adjusted to suit different cement types and sand qualities.

Key Benefits

• Protects against moisture damage, adding longevity to renders and screeds.
• Inhibits salt passage, preventing unsightly efflorescence on finished surfaces.
• Offers flexibility for both indoor and outdoor use, providing consistent performance.
• Retains mortar usability, enabling smoother application even in varying conditions.

Practical Applications

The Sika Rendermix is ideal for a range of rendering and screeding tasks. Its versatility supports professional-grade finishes across multiple project types.

• External rendering to protect walls from moisture ingress.
• Internal screeding to create smooth, durable floor bases.
• Pebble-dashing and roughcast finishes for aesthetic and functional improvements.
• Bonding multi-layer renders to ensure robust structural adherence.

How This Fits Into a Typical Job

This admixture is incorporated during the mortar mixing stage, added to the gauging water before combining with sand and cement.

Once mixed, it becomes part of the render or screed that is then applied to prepared surfaces, improving water resistance and workability throughout the application process.

How to Use

1. Surface Preparation:
   • Make sure the substrate is clean, firm, and free from grease, dirt, or loose material.
   • For porous surfaces, pre-wet and apply a bonding slurry before proceeding.
2. Mixing:
   • Add Sika Rendermix directly into the gauging water before combining with sand and cement. For larger batches, mix with an electric power mixer to achieve a consistent blend.
3. Application:
   • Spread the render or screed while the bonding slurry is still wet for superior adhesion.
   • For multi-layer applications, scratch the surface of each layer to aid binding.
4. Layer Thickness:
   • Keep subsequent layers thinner than the preceding ones for optimal performance.
5. Curing:
   • Allow sufficient drying time and avoid exposure to extreme weather during curing.

Storage and Maintenance Tips

• Store in a cool, dry place away from direct sunlight to maintain product effectiveness.
• Seal the container tightly after use to prevent contamination or leakage.
• Regularly check the shelf life (24 months) to maintain optimal performance.
