Technical Information

IMPORTANT NOTE

SikaPower®-2900 Primer contains solvent which may dull the surface finish of some freshly applied paints. Preliminary trials must be carried out. Never apply to porous substrates since it may not dry completely and might influence the adhesive or sealant. Protect adjacent surfaces by masking where necessary. It must not be used for tooling/smoothing of products and as a cleaning agent.

Application

Method of Application

METHOD OF APPLICATION

Preparation

Surfaces must be clean, dry and free from grease, oil, dust and contaminants.

Application

Use the aerosol can and apply the primer in a thin and even coat to the surface in short bursts to avoid dripping or running of the primer. Ideal application and surface temperature is between 15 °C and 25 °C. SikaPower®-2900 Primer has to be applied once only. If pre-treated area is not bonded within the maximum flash-off time, the activation process has to be repeated (once only). Consumption and method of application depends on the specific nature of the substrates.
