Before adding the components, WIDOCRYL-SP has to be stirred thoroughly. First, WIDOCRYL-SP Powder will be mixed in (mixing ratio: SP-Powder 1,5 kg : 1,0 kg WIDOCRYL-SP). Then, the hardener is added. The amount of hardener needed depends on the temperature. The dosage is mentioned on the lid of the packaging. Both components should be stirred thoroughly (stirring time approx. 2 min.). Due to the short pot life after the hardener has been added, 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. Afterwards, approx. 2,8kg/m² quartz sand (grain size 0,3 – 0,8 mm) is sprinkled into the wet WIDOCRYL-SP.
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.
