Shelf life

store in unopened packaging in a dry area for up to 12 months

At 68° F (+20 °C ) and 65% relative humidity. Higher temperature and low humidity decreases, lower temperature and high humidity increases this value respectively.

Avoid air entrapment doing exterior installations. Apply mortar on substrate and the backside of tiles (buttering-floating procedure).

Substrate preparation

The substrate must be ready for installation, dry, clean and load bearing. If installation occurs on shrinking substrates frequent expansion joints should be included in the layout.
Prime absorbent substrates in interior areas with Okamul GG or Okatmos® UG 30. Allow a drying time of at least 24 hours over calcium sulfate screed. Prime non-absorbent substrates with Okatmos® UG 30.
In exterior areas apply a contact layer of adhesive mortar and let it set.

Processing

Mix ServoStar® 2000 Flex with clean water to a smooth texture. Allow mixture to slake for approx. 5 minutes and stir again. Use appropriate notched trowel (see table) to apply mortar onto substrate, slide the covering material into the adhesive bed within 25 minutes and press tightly. Depending on the absorbency of the substrate/covering corrections can be made within 25 minutes.

Cleaning

Clean tools and tile surface immediately with water.

The information is based on our experience and is to be regarded as general instructions. We cannot guarantee successful results since we do not have any influence on the conditions at the construction site and the proper processing. In any case a sample application is recommended before the installation.
