Needed tools, installation instructions

Application equipment / tools
Mixing of the product:
- Suitable mixer (ex. paint mixer)

Applying of the product:
- Sheepskin roller
- Brush (only for areas not accessible with the roller)

Substrate preparation
ALSAN 178 must only be applied to a prepared substrate.
Please refer to the appropriate application guide for information about correct surface preparation.

First stir the tub contents thoroughly. Then add the catalyst whilst stirring at a low speed for 2 minutes.
Make sure that all material on the side and base of the pot is mixed in. At temperatures below 10 °C the
product should be stirred for 4 minutes as the catalyst will take longer to dissolve.

Use the sheepskin roller to apply an even film‐forming coat of primer.
Avoid creating puddles of primer.
