Practical Applications

The Sika 1 Waterproofer is ideal for safeguarding various structures against moisture, whether below or above ground. It excels at creating watertight screeds, moisture-resistant renders, and general-purpose mortar waterproofing.

• Below-Ground Structural Protection: Perfect for cellars, basements, and vaults to resist water pressure.
• Above-Ground Damp-Proofing: Ensures walls remain free from damp patches in challenging conditions.
• Internal Tanking: A trusted choice for waterproofing water tanks and reservoirs.
• Replastering After DPC Injection: Provides a reliable finish for areas treated for rising damp.

How This Fits Into a Typical Job

This admixture is integrated during the mixing stage of cement-based materials. It becomes part of the render, screed, or mortar preparation before application to surfaces.

In waterproofing projects, it functions as an integral component of the protective system, working within the material matrix to block water ingress rather than being applied as a surface coating.

How to Use

1. Surface Preparation:
   • Ensure surfaces are clean, sound, and free of debris or contaminants.
   • Remove any loose or flaking material to allow proper adhesion.
2. Mixing:
   • Add the required amount of Sika 1 Waterproofer to your cement mix. The correct ratios are in the product guidelines.
3. Application:
   • Apply the mixture using a trowel or appropriate tool, ensuring an even layer.
   • For renders or screeds, build up layers as necessary for the desired thickness.
4. Drying Time:
   • Allow sufficient drying between coats or layers; conditions may vary depending on humidity and temperature.
5. Final Curing:
   • Protect the treated area from adverse weather or mechanical stress during the curing period.
