IMPORTANT NOTE
SikaForce®-300 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 adhesion or the properties of the adhesive.
Protect adjacent surfaces by masking where necessary.
SikaForce®-300 Primer must not be used for tooling/smoothing or as cleaning agent.
Application
Preparation
Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
Application
SikaForce®-300 Primer has to be processed between 15 °C and 30 °C (product, ambient, and substrate temperature).
SikaForce®-300 Primer has to be applied in a thin and even coat to the surface in short bursts to avoid dripping or running of the primer.
If pre-treated area is not bonded within the maximum flash-off time, the pre-treatment process has to be repeated (once only).
Consumption and method of application depends on the specific nature of the substrates.
