Before adding the hardener, WIDOCRYL-Topsiegel OS has to be stirred thoroughly. The amount of hardener needed depends on the temperature. The dosage is mentioned on the lid of the packaging. The components have to be stirred thoroughly (stirring time approx. 2 min.). Due to the short pot live after having added the hardener, we recommend to prepare only small amounts.


The finished mixture is spreaded on the surface. It can be spreaded/applied with a rubber slider or a squeege and then treated with a paint roller.

Further details, especially regarding hazard statements, security advices and measures in the event of fire can be found in the safety data sheet under sections 2, 4, 5, 6, 7 and 8.
