SikaBond® AT Universal has a shelf life of 12 months from the date of production, if it is stored properly in undamaged, original, sealed packaging, and if the storage conditions are met.

SikaBond® AT Universal shall be stored in dry conditions, protected from direct sunlight and at temperatures between +5 °C and +25 °C.

SikaBond® AT Universal is resistant to water, seawater, diluted alkalis, cement slurry and water dispersed detergent.
SikaBond® AT Universal is not resistant to alcohols, organic acids, concentrated alkalis and concentrated acids, chlorinated and aromatic hydro-carbons.

SikaBond® AT Universal is not or is only temporarily resistant to concentrated mineral acids, organic solvents (kelones, esters, aromatics) and alcohol, lacquer and paint thinners, organic acids and caustic solutions or solvents.

For the application of SikaBond® AT Universal all standard construction guidelines apply.

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. SikaBond® AT Universal 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 (<6 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 Sika Technical Service.
 

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.
