SikaLatex®-100 Power LK

High performance SBR based multipurpose polymer for waterproofing, repair and bonding

SikaLatex®-100 Power LK is a latex-based, water-resistant multipurpose admixture for use in areas subject to humidity, dampness and continuous water contact. When added to cement mixtures, it improves water resistance and bonding strength by forming a reinforcing polymer that increases long term durability and flexibility of the mix. It is fully soluble in water and is to be added directly to the gauging water of mortar, concrete or cementitious grout.

  • Multipurpose 7-in-1 application
  • Makes the mortar waterproof
  • Improves resistance to salt permeation Improves toughness and flexibility and reduces cracking
  • Good adhesion to substrates like concrete, stone, brick etc.
  • Reduces viscosity of cement injection grout and improves bond of cured injected materials with substrates
  • Dilute with water up to 6 times depending on the type of application
  • Reduces surface dusting of concrete
  • Improves chemical resistance of concrete
  • Improves frost resistance
  • Good resistance to water and water vapour Reduces water cement ratio for equivalent workability
  • Mixes may be applied in much thinner sections

NOTE: The above stated consumption depends on substrate condition, porosity, level, application skills and mixing ratios. Mix consistency may change with the quality of sand and cement, hence gauging water may be adjusted slightly based on site conditions. Additional plasticising admixture may be necessary for concrete, screed or grouting applications to maintain desired workability
Application steps

SUBSTRATE QUALITY

The substrate shall be sound, clean, homogeneous, free from oils and grease.

SUBSTRATE PREPARATION

  • Dust, loose or friable particles, rust, scale, paint, cement laitance, old coatings and any other contaminants or deleterious materials which reduces bond or contributes to corrosion shall be removed by suitable means before application.
  • Smooth substrates must be mechanically roughened by scabbling, needle gun or grit blasting to provide an adequate key.
  • Cementitious substrates should be pre-saturated surface dry (SSD) with clean water at least 2 hours before any application.

MIXING

MIXING

  1. Mix SikaLatex®-100 Power LK with the correct amount of water to produce a gauging solution.
  2. Pour part of the gauging solution into a suitable mixing container.
  3. While stirring slowly, add the cement or cements and mix to the gauging solution and mix thoroughly until a smooth, uniform and lump-free mix is achieved.
  4. Within the mixing time add additional gauging solution to adjust to the desired consistency. Mix either by hand or with a low speed drill for not more than 2 minutes.

NOTE: When a concrete-mixer is used, pour the mortar as soon as its consistency is cohesive. Do not run the mixer too long.

APPLICATION

IMPORTANT

Avoid application in direct sun and/or strong wind.

IMPORTANT Protect freshly applied material from rain etc.

IMPORTANT During application, the mixture of SikaLatex®-100 Power LK and cement needs to be continuously stirred to prevent the cement particles from settling

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be removed mechanically.
