Application steps

SUBSTRATE PREPARATION

The steel surfaces should be grit blasted or wire brushed to remove all traces of corrosion. Ensure no oil, grease or dust is present. Surfaces should be dry.
Apply SikaEmaco®-8100 AP immediately after completion of preparation to prevent any contamination. Do not leave blasted or prepared steel uncoated.

MIXING

SikaEmaco®-8100 AP should be thoroughly stirred prior to application.

 

APPLICATION

Brush the SikaEmaco®-8100 AP onto the prepared substrate, ensuring uniform and full coverage, particularly on the back face of reinforcement. Only one coat of SikaEmaco®-8100 AP is required.
Repair mortars can be applied as soon as the SikaEmaco®-8100 AP is dry.
