Description

Sika SikaMix Integral Liquid Waterproofer Additive 5 Litre 877539

MPN: 877539

Barcode: 5029347002251

This liquid admixture improves the durability and water resistance of cement-based materials for demanding construction or repair tasks.

Who This Product Is For

This product is designed for construction professionals, builders, and experienced DIY users working on projects that require enhanced water resistance in cement-based materials.

It suits those handling below-ground structures, external rendering, tank linings, and other areas exposed to moisture or dampness.

Key Features

  • Water Resistance: Reduces water permeability, safeguarding surfaces from moisture damage.
  • Air Entraining Agent: Retains mix integrity without compromising workability.
  • Improved Strength: Improves compressive strength for durable, long-lasting results.
  • Low Toxicity: Safer handling during use, suitable for various environments.
  • Corrosion Protection: Does not corrode steel reinforcements or ties, helping preserve structural integrity.

Practical Applications

The Sika SikaMix Integral Liquid Waterproofer excels across a range of challenging tasks, making it useful for professionals and DIY users. Its versatile design enables effective performance in the following ways:

  • Sealing pool and tank linings to prevent water leakage.
  • Creating waterproof screeds for below-ground structures.
  • External rendering and pointing to resist rainwater penetration.
  • Protecting roof areas from moisture and dampness.
  • Strengthening mortar mixes for extended durability in harsh conditions.

How This Fits Into a Typical Job

This liquid waterproofer is added during the mixing stage of cement-based materials preparation. It becomes an integral part of the mortar, render, or concrete mix before application to surfaces that require water resistance.

It functions as a single additive that provides multiple protective properties, eliminating the need for separate admixtures during the mixing process.

How to Use

  1. Preparation:
    • Make sure all surfaces are clean, free of debris, and structurally sound. Remove any loose material before mixing.
  2. Measuring:
    • Add the recommended amount of the liquid waterproofer to your sand-cement mix in a sturdy mixing bucket.
  3. Mixing:
    • Blend thoroughly to achieve a consistent mix, so the waterproofer is evenly distributed throughout. For larger batches, mix with an electric power mixer.
  4. Application:
    • Apply the mixture as required, whether for rendering, screeding, pointing, or other tasks.
  5. Curing:
    • Allow sufficient drying and curing time based on environmental conditions and the thickness of the applied layer.
  6. Post-Care:
    • Clean tools immediately after use to prevent residue build-up.
