Application areas

Sikaflex Tank N should only be used by professional applicators.
Sikaflex Tank N has been designed for use in environments used for the storage, filling and handling of water polluting liquids such as: floor joints in gas stations, joints in handling areas, tanks storage and containment, and floor expansion and connection joints in car parks.

Application

1. The support must be clean and dry, sound, homogeneous, free of oil, grease, dust and friable or loose particles.
2. Cement laitance must be removed.
3. Sanding the surface of non-porous substrates with a very fine abrasive pad can improve the adhesion of Sikaflex Tank N.

The Sikaflex Tank N joint system is certified for application between uncoated precast concrete elements.
Sikaflex Tank N has technical approval for use in areas for the storage/filling/handling of water-polluting liquids, or concrete grades ≥C35/C45 and ≤C50/60 (EN 206-1), or between cast-in-situ concrete elements classified according to DIN 1045 as "FD" (liquid-tight concrete) or "FDE" (concrete tested against liquid penetration).

Non-porous substrates:

• Aluminum, anodized aluminum, stainless steel, galvanized steel, thermo lacquered powder-based metals or vitrified tiles must be cleaned and then pre-treated with Sika Aktivator-205 using a cloth own.
  Maintain an evaporation time of at least 15 minutes (maximum 6 hours) before applying the mastic.
• Other metal surfaces such as copper, brass and titanium zinc should also be cleaned and then pre-treated with Sika Aktivator-205 using a clean cloth.
  After the necessary evaporation time, apply a coat of Sika Primer-3 N using a brush.
  Maintain an evaporation time of at least 30 minutes (maximum 8 hours) before applying the mastic.
• The PVC must be cleaned and then pre-treated with Sika Primer-215 using a brush.
  Before applying the mastic, let the primer dry for at least 30 minutes (maximum 8 hours).

Porous substrates:

• Concrete, aerated concrete, cementitious plasters, mortars and bricks must first be primed with Sika Primer-215 for applications according to ETA-09/0272, or Sika Primer-3 N applied with a brush or clean roller.
  Allow a minimum drying time of 30 minutes (max. 8 hours) before applying the mastic.
