Application steps

SUBSTRATE PREPARATION

Surfaces of cracks, joints and voids need to be clean, free of loose particles, dust, oil and any other bond-breaking substances.

Any dirt must be blown out with compressed air.

 

MIXING

Empty parts A and B into a dry clean mixing vessel and stir slowly (ma. 250 rpm) and thoroughly for ~2 min until homogeneous.

Observe the safety precautions. Containers are supplied according to the required mixing ratio of 1:1 parts by volume.

After mixing pour the material into the pumps feed container (hopper) and use within potlife.

If 2-component pumps are used the product can be pumped directly from the containers and will be mixed in a static mixer.

When using accelerator SikaInject® AC 20, measure the required quantity and pre-mix into part A of the base resin. 

CLEANING OF EQUIPMENT

Use SikaInject® Cleaner C1 or SikaInject® CL2 for pump-cleaning (non-cured resin). Cured material can only be removed mechanically.
