Feb Rendamix 5 Litre is a liquid waterproofer water resistant retarding and plasticiser admixture which prevents transmission of water through sand or cement renders, also improves the workability of the product. Renda Mix also acts as an inhibitor for efflorescence. As an admixture to exterior or above ground cementitious render finishes such as dashing, harling, rough cast and internally after installation of injection DPC’s.

Feb Rendermix has good air entraining and retarding properties allows larger working areas to be covered in a single application process, significant improvement in resistance to water penetration, reduction in water demand of the mix resulting in reduction in water bleed both on the spot board and in situ.

Main Points

• 3 in 1 water proofer plasticiser and retarder
• 5 Litre easy to use tub
  
• Significant improvement in resistance to water penetration
• RENDAMIX also acts as an inhibitor for efflorescence.
  
• Low toxicity
• Reduces surface absorption
• Improves workability
• Easier application in render mixes

How To:

The substrate to which the render is to be applied should be thoroughly sound and uncontaminated.

Any existing coatings must be removed prior to the commencement of rendering.

When the substrate is highly porous, long term bond and durability can be improved by the use of a bonding slurry consisting of cement and FEBOND SBR mixed at 1-2:1

This should be applied to the prepared substrate immediately prior to application of the render, which should be applied wet on wet.

Feb Rendamix is supplied ready to use and should be added to the mixing water at a rate of one part Feb Renda-mix to 20/40 parts water.

This corresponds to a dosage rate of 500 ml to 1000 ml per 50 kg of cement.

The plasticising action of Feb Rendamix should be used to full effect by reducing the water cement ratio a reduction in water content up to approximately 20% is achievable compared to an un-plasticised mix. Care should be taken not to overmix.

Dosage:

500 ml to 1000 ml per 50 kg kilos of cement.

FAQs About Feb Rendamix Render Waterproofer, Retarder, and Plasticiser – 5 Litre

1. What is Feb Renda mix used for?

2. How does this product improve render mixes?
   It enhances workability, reduces shrinkage, increases water resistance, and extends setting time, making it easier to apply and providing a more durable finish.

3. Can it be used for external rendering?
   Yes, it is suitable for external rendering applications, providing enhanced water resistance to protect against damp and weathering.

4. How much should I use per mix?
   Use approximately 250ml per 25kg of cement, depending on the desired effect and application.

5. Does it affect the strength of the mix?
   No, it improves the performance and durability of the mix without compromising its strength.

6. Is it suitable for DIY users?
   Yes, it is easy to use and ideal for both professional contractors and DIY enthusiasts working on rendering projects.

7. Can it be used with other additives?
   It is a standalone product that combines multiple functions, so additional plasticisers or retarders are typically not required.

8. Is it effective in cold weather?
   Yes, its retarding properties ensure controlled setting times, even in colder conditions.

9. Does it improve adhesion to surfaces?
   Yes, the plasticising effect enhances adhesion, ensuring a smooth and even application.

10. Why choose Feb Rendamix over other admixtures?
    Its all-in-one formula combines water resistance, improved workability, and extended setting times, simplifying the mixing process and delivering professional results for every project.
