Sikaflex®-11 FC+ has a shelf life of 15 months from the date of production, if it is stored properly in undamaged, original, sealed packaging, and if the storage conditions are met.

Sikaflex®-11 FC+ shall be stored in dry conditions, protected from direct sunlight and at temperatures between +5 °C and +25 °C.

Sikaflex®-11 FC+ is resistant to water, seawater, diluted alkalis, cement grout and water dispersed detergent.
Sikaflex®-11 FC+ is not resistant to alcohols, organic acids, concentrated alkalis and concentrated acids, chlorinated (hydro-carbons) fuel.

For detailed information please contact our Technical Service Department.

−40 °C to +80 °C

The joint width must be designed to suit the joint movement required and the movement capability of the sealant. The joint width shall be ≥ 10 mm and ≤ 35 mm. A width to depth ratio of 1:0.8 for floor joints and 2:1 for facade joints must be maintained.
 

Standard joint widths for joints between concrete elements:

All joints must be correctly designed and dimensioned in accordance with the relevant standards, before their construction. The basis for calculation of the necessary joint widths are the type of structure and its dimensions, the technical values of the adjacent building materials and the joint sealing material, as well as the specific exposure of the building and the joints.
 

Joints ≤ 10 mm in width are for crack control and therefore non-movement joints. What is relevant is the joint width at the time of application of the sealant (guide value of +10 °C).

For larger joints please contact our Technical Service Department.

Use closed cell, polyethylene foam backing rods.

+5 °C to +40 °C, min. 3 °C above dew point temperature

30% to 90%

+5 °C to +40 °C

Approximate consumption for floor joints

Minimum joint width for perimeter joints around windows is 10 mm.

The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed. Sikaflex®-11 FC+ adheres without primers and/or activators.
However, for optimum adhesion and critical, high performance applications, such as on multi-story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming and/or pre-treatment procedures shall be followed:
 

Non- porous substrates
Glazed tiles, powder coated metals, aluminium, anodised aluminium, stainless steel and galvanised steel have to be treated with a very fine abrasive pad and Sika® Aktivator-205 shall be applied using a clean towel. Before sealing allow a flash-off time of > 15 minutes.
All metal surfaces that are not mentioned above have to be treated with a very fine abrasive pad and Sika® Primer-3 N shall be applied using a clean brush or roller. Before sealing allow a flash-off time of > 30 minutes (< 8 hours).
PVC has to be pre-treated with Sika® Primer-215 applied with a clean brush. Before sealing allow a flash-off time of > 30 minutes (< 8 hours).
 

Porous substrates
Concrete, aerated concrete and cement-based renders, mortars, brick, and natural stone have to be primed with Sika® Primer-3 N applied with a clean brush. Before sealing allow a flash-off time of > 30 minutes (< 8 hours).
 

For detailed advice, please contact our Technical Service Department.
 

Note: Primers are adhesion promoters. They are neither a substitute for the correct cleaning of a surface, nor do they improve the strength of the surface significantly.

Clean all tools and application equipment immediately after use with Sika® Remover-208 and/or Sika® TopClean T. Once cured, residual material can only be removed mechanically.
