storage:
Store in undamaged and unopened original packaging in a dry place out of direct sunlight. Frost susceptible.
disposal:
Disposal must be in accordance with the pertinent national and local regulations. Hardened materials
may be disposed of with regular
household/commercial waste. Cartridges containing residual paste must be treated as colour waste.

Processing/ Mixing:
Allow the hardener component ( component B ) to flow completely into the master component (component A ). Mix intensively with a slowly rotating stirrer (recommendation: double stirrer with counter-rotating stirrer shafts).
Repot into another receptacle and mix thoroughly again.
The compound must be homogeneous, streak-free before application.

Sealing of fibre cement distance tubes with fibre cement plugs:
After cleaning the inside of the fibre cement distance tubes and removing the loose material, the fibre cement plug is dipped into the PROTECT BK and inserted into the distance tube.
The quantity of PROTECT BK on the plug must be sufficient to ensure that the fibre cement plug is fully glued to the inside of the distance tube over its full length.
Depending on the requirements of the construction site, several fibre cement plugs may have to be installed.

Bonding of concrete components:
Depending on the application, PROTECT BK is evenly applied to the components to be bonded using a spatula, smoothing trowel, toothed trowel or similar.
Make sure that the entire surface is bonded without voids.
Immediately after applying the adhesive, the surfaces to be bonded are pressed together and weighted if necessary. For vertical or overhead bonding, the components must be fixed for at least 12 hours,
depending on temperature and layer thickness.
PROTECT BK can be applied in layer thicknesses of 1 - 20 mm.

Please note:
The relative humidity must not exceed 80 %.
Ensure good ventilation after application and during hardening.
Depending on the substance, concentration and duration of exposure, exposure to chemicals can lead to colour changes on the surface which, however, do not affect functionality.
When exposed to UV rays, epoxy resins generally show a certain colour change and chalking.
