WIDOCRYL-Concrete Primer PM

WIDOCRYL-Concrete Primer PM

Surface preparation

The surface must be solid and free of dust, fat and oil. Loose and hollow tiles must be removed. Laitance and loose particles must be removed thoroughly, e. g. by shot blasting.


It should be noted that the amount of catalyst powder to be added depends upon the substrate temperature. For further details, see container lid.

The primer should be applied as a sealed film with blanket coverage and in principle should be sprinkled with quartz sand of grain size 0.3 – 0.8 mm. If this cannot be achieved within one working process, a second priming layer has to be applied (note: only the top layer should be sprinkled with quartz sand).

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.
