Primers, Finish Paints & Rendering

Primer Sealer

The use of this vapour permeable primer sealer Klaas coatings is a FireCrunch warranty requirement.

ALL MgSO4 boards are effectively breathing materials and this primer sealer allows that to continue even after using water based paints or extra waterproofing membranes where maybe required in heavy duty industrial use. The primer sealer S1 is a waterproofing application for internal and external residential and commercial use.

Once the S1 primer is applied any water based finishing paint or texture paints may be used.


First consult the manufacturers instructions and refer back to Fire crunch if more info is required.  A large range of renders have been used on FireCrunch MgSO4 K-Clad products over the past 9 years further info technical@firecrunchaustralasia.com.au or 1300 933 102
