Sika® Igolflex®-130 is a water-based waterproof coating prepared by special processes after using high polymer modified bitumen such as SBS and APP. It has excellent application performance and service performance. After cured, it has excellent elastic-plastic property, low temperature flexibility and aging resistance.

  • Single component, cold applied
  • Non-toxic, odorless, and pollution-free
  • Capable of thick coating, saving labor and time
  • Safe and convenient application, excellent adhesion to concrete, wood, and asbestos tile, even on wet substrate
  • Moves with normal thermal movement – Retains flexibility even at low temperatures
  • High temperature resistance, corrosion resistance

Application

SUBSTRATE QUALITY

The quality of the substrate is directly related to the service life of the waterproof layer, so the substrate must meet the following conditions:

  • The cement mortar or concrete grade must meet the design requirements
  • The substrate should be solid, flat, free of concavities, pits, sand, etc.
  • The root of the parapet wall should be rounded with a radius not less than 50mm

MIXING

Mechanical mixing is not required. Product should be manually stirred with a plastic spatula until a smooth consistency is obtained.

APPLICATION

Priming:

Add ~20-50% fresh water (by weight) to Sika® Igolflex®-130 and mix thoroughly. Prime the surface by brush or spray. Allow to completely dry prior to the application of further coatings. In case of porous, absorbent substrates pre-wet the surface with water. Avoid standing water.

    

Application:

Sika® Igolflex®-130 is applied using a wide nylon brush, sheepskin disposable rollers or by spraying.

The product should be applied in 2 or 3 coats of 0.6 - 0.8 kg/m² (depending on application requirements), allowing each coat to dry fully before the next coat is applied. Subsequent coats should be applied at right angles to the previous coat. The product must not be applied in wet conditions or exposed to water until it has fully dried.

Waiting time between coats is 4-6 hours, depending on ambient conditions.

The waterproofing system should be allowed to cure for at least 72 hours prior to overlaying with screed.

For large areas, a polythene sheet should be placed to isolate the screed from Sika® Igolflex®-130 membrane. At day joints, Sika® Igolflex®-130 membrane should overlap the existing cured membrane by at least 100 mm. 

   

Notes on Application / Limitations

  • The application should start from detailing and then conduct large-scale rolling
  • The coating should be applied 2-3 coats, and its thickness should not be less than 1mm.
  • As Sika® Igolflex®-130 is not long term UV resistant therefore exposed surface (e.g. flat roof) must be protected (e.g. over coated with reflective paint or protective mortar screed) as soon as possible after application.
  • Not to be used as a traffic bearing surface.
  • Do not thin with solvents.
