Everbuild Opti-mix Super Concentrate Render Additive – 3-in-1 Formula (697962)

Everbuild 3-in-1 Concentrated Render Additive 1 Litre

REF: OPTIREND1 | MPN: 697962 | Barcode: 5029347609917

A concentrated render additive that provides waterproofing, plasticising, and open-time extending functions in one formula.

Who This Product Is For

This product is intended for trade professionals including plasterers, renderers, and builders, as well as experienced DIY users working on rendering or concrete projects.

It is suitable for external rendering work, mortar applications for pools and tanks, pointing in outdoor environments, concrete and screed mixes, and below-ground structures.

Key Features

• Concentrated formula: One litre can replace up to 25 litres of standard additives.
• Multiple functions: Acts as a waterproofer, air-entraining plasticiser, and open-time extender.
• Reduces water absorption: Incorporates pore-blocking technology to limit water uptake and improve resistance to freeze-thaw cycles.
• Enhances workability: Produces a smooth, workable mix for application over large areas.
• Reduces cracking and shrinkage: Supports the curing process to help minimise these issues.
• Reduces need for multiple admixtures: Combines three functions in one product.
• Extends open time: Allows larger areas to be completed in a single session.

Practical Applications

The Everbuild Opti-Mix Render Additive is suitable for:

• External rendering projects; for poor or friable substrates, prime first with a bonding coat such as Everbuild 507 Rendagrip Extra-Grip Render Bonding Coating 10L.
• Mortar applications for pool and tank linings, offering improved water resistance.
• Pointing work, especially in outdoor environments exposed to weathering.
• Concrete and screed mixes, improving plasticity and reducing the risk of cracking.
• Structures located below ground level, benefiting from improved waterproofing properties.

How This Fits Into a Typical Job

This additive is used during the mixing stage when preparing render, mortar, or concrete. It is added to the gauging water before combining with dry ingredients.

The product improves workability during application, extends the working time for larger areas, and provides waterproofing properties that become active as the mix cures.

Specifications

• Concentration: One litre replaces up to 25 litres of standard additives.
• Mixing ratio: 20-40 ml per 50kg of cement.
• Maximum water dilution: Up to 10 litres of water.
• Application method: Add to gauging water, not directly to dry ingredients.
• Storage: Store in a cool, dry place away from direct sunlight.

Usage Instructions

1. Preparation: Shake the bottle thoroughly before use.
2. Measuring: Push the lid down and twist anti-clockwise to open. Squeeze the bottle to fill the measuring cup with 20-40 ml of additive per 50kg of cement.
3. Mixing: Add the measured additive to a bucket of water (up to a maximum of 10 litres) and stir well.
4. Dry mixing: Combine all other dry ingredients separately before gradually adding the prepared solution until the desired consistency is achieved.
5. Application: Never add the product directly to dry ingredients. For best results, always incorporate it into the gauging water.

Storage and Maintenance

• Store the bottle in a cool, dry place away from direct sunlight.
• Always reseal tightly after use to prevent contamination or spillage.
• Clean all tools and equipment immediately after use to avoid residue build-up.
• For applying protective coatings or sealers after curing, use a suitable roller kit for an even finish.

Everbuild 3-in-1 Concentrated Render Additive is designed for rendering and concrete projects requiring improved workability, extended working time, and waterproofing properties.

• Product FAQs

  Q: What makes this product different from standard additives?
  A: Its triple-action formula combines waterproofing, plasticising, and open-time extension into one highly concentrated solution, simplifying the mixing process and delivering superior results.
  Q: Can this product help prevent efflorescence?
  A: Yes, it contains pore-blocking additives that reduce water absorption, significantly lowering the risk of efflorescence over time.
  Q: Is this suitable for below-ground applications?
  A: Absolutely. This product improves water resistance and durability, making it ideal for below-ground structures like basements or retaining walls.
  Q: How does this additive improve workability?
  A: By forming stable air bubbles in the mix, it creates a smooth, buttery texture, making application over large areas much easier and more efficient.
  Q: Do I need additional waterproofing products when using this additive?
  A: No, this product eliminates the need for separate waterproofing admixtures, as its formula already incorporates effective water-resistant properties.
  Q: What precautions should I take during use?
  A: To achieve optimal results, avoid exceeding the recommended dosage and ensure thorough mixing. Never add the product directly to a dry mix; always dilute it in gauging water first.
