This waterproof adhesive, sealer, and bonding agent is designed for both internal and external applications on building materials.

Who This Product Is For

This product is designed for building professionals and serious DIY users undertaking construction or renovation work.

It suits tasks involving surface bonding, waterproofing, and preparation of porous building materials like concrete, brick, and plaster.

Key Features

• Waterproof Formula: Maintains integrity when exposed to moisture, suitable for outdoor use.
• Multi-Surface Application: Bonds to porous surfaces such as concrete, stone, and brick.
• Dust-Proofing Capability: Strengthens and stabilises renders, floors, and screeds, reducing surface dust.
• Application Methods: Can be applied with a brush or roller, or mixed directly into cement.
• Bonding Agent: Forms connections between materials, reducing need for extensive surface preparation.

Practical Applications

This product is used for sealing, bonding, and strengthening surfaces across building projects:

• Bonding new concrete to existing surfaces without additional keying.
• Improving plaster and render finishes.
• Toughening screeds and floors in high-traffic areas.
• Securing wood, cork, textiles, and paper in general-purpose applications.

For small repairs, follow with a rapid repair patching plaster to achieve a finished surface.

How This Fits Into a Typical Job

This product is typically used during surface preparation, applied as a primer or bonding agent before laying plaster, screed, or render.

It creates a stable base that improves adhesion and waterproofing for subsequent layers in the workflow.

How to Use

1. Surface Preparation:
   • Make sure all working surfaces are clean, stable, and free from debris, oils, or standing water.
   • Remove any loose or flaking material to create a solid base.
2. Mixing:
   • Shake the container thoroughly before use to recombine ingredients.
   • Dilution may be necessary based on the porosity of the surface—refer to the technical data sheet for specific guidance.
3. Application:
   • Apply the product using a plastering trowel, brush or roller, or mix it directly into your cement mixture.
   • Allow the primer coat to dry fully before laying the bonding coat.
4. Bonding:
   • For best results, apply plaster, screed, or render while the bonding coat remains tacky.
5. Finishing Touches:
   • On non-absorbent surfaces, the sealing coat can be omitted if unnecessary.

  Q: Can this be used as a primer for non-porous surfaces?
  A: Yes, it can be applied as a primer; however, non-absorbent surfaces may not require a sealing coat. Always test a small area for compatibility.
  Q: Is this product safe to use indoors?
  A: Absolutely. It is formulated for both internal and external use, offering the same level of effectiveness in either environment. Ensure adequate ventilation during application.
  Q: How does this compare to standard PVA adhesives?
  A: Unlike standard PVA, this product will not re-emulsify when exposed to moisture, making it more durable and reliable in challenging environments.
  Q: Can it be used as a dustproofer for floors?
  A: Yes, it’s perfect for stabilising and toughening dusty floors and screeds, creating a more durable and cleaner surface.
  Q: What dilution ratio should I use for priming?
  A: The dilution ratio depends on the porosity of the surface. Refer to the technical data sheet for detailed recommendations to achieve the best results.
