Sika®-1 Waterproofer 5L

Sika®-1 is a general and structural waterproofing admixture designed to provide effective water protection for concrete and mortar surfaces. When mixed with ordinary Portland cement and water, it blocks the capillaries and pores in the cementitious system, creating a barrier against the transmission of liquid water. Ideal for both emergency and long-term waterproofing applications, Sika®-1 is suitable for use in basements, swimming pools, tunnels, water tanks, and many other concrete and masonry structures.

Features:

  • Normal setting liquid waterproofing admixture for mortar and concrete.
  • Blocks capillaries and pores to provide an effective water barrier.
  • Increased impermeability of mortar and concrete.
  • Ready to use—simply add water and ordinary Portland cement.
  • Easily dispersed for uniform mixing and application.
  • Chloride-free, ensuring safe use in reinforced concrete applications.

Application:

  • Before starting work, wear suitable protective clothing, gloves, and goggles.
  • Mix Sika®-1 with clean water at the recommended dilution ratio (1 part Sika®-1 to 10 parts water) based on application needs and water pressure.
  • Pour the liquid into a clean mixing container.
  • Add cement until the liquid is fully covered (approximately 3 parts cement to 1 part liquid).
  • Mix thoroughly into a uniform paste and apply immediately.
  • Only prepare as much product as needed for immediate use.
  • Apply the prepared mixture to the surface by molding it into a plug and pressing firmly into holes or cracks to seal them.
  • For medium to heavy water infiltration, use Sika®-1 to divert water into discharge points formed with short plastic tubes bonded into drilled holes.
  • Allow the final waterproofing render to fully set before applying any additional coatings.
  • In high water pressure areas, increase the surface area around discharge tubes to ensure a strong bond for the Sika®-1 paste.

Cleaning:

  • Clean tools and equipment immediately after use with water to avoid hardened residue.
