Application

Application Information

Ambient air temperature

+0°C min. / +40°C max.
At temperatures below +5°C the tape and the substrate must be warmed before and during the application. Use hot air equipment.

Substrate moisture content

The substrate must be dry.
Application steps

SUBSTRATE PREPARATION

The substrate must be sound, clean, dry and free from all surface contaminants.
All loose particles, release agents, laitance, paint, rust and other poorly adhering materials must be removed by suitable hand or mechanical preparation techniques.

Metallic substrates, plastics etc. have to be thoroughly cleaned with a solvent (e.g. Sika® Cleaner-205). Allow the solvent to completely evaporate before the tape is applied.

On porous substrates (concrete, renderings, etc.) the adhesion can be improved with a butyl primer (e.g. Primer 130) Let the primer dry for at least 1 hour.
