ParaFlex Universal Primer is a multi-purpose primer for use with ParaFlex FD, Liquid Applied Waterproofing Membrane. Consisting of a 1-component Polyurethane pre-polymer elastomer with aromatic + IPDA cross linking agents ParaFlex Universal Primer can be used on virtually any substrate, and offers adequate protection against alkalinity.
ParaFlex Universal Primer hardens with exposure to air making it particularly economical to use. The addition of cross linking agent ensures rapid curing even at low temperatures.
Tests should generally be made on curing and adhesion to the substrate.
The surface to be primed must be dry, free from dust, grease or oil, and have good adhesion and load-bearing properties.
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 to 0.7 mm or 0.4 to 0.8 mm.
Curing time: ParaFlex FD can be applied after approx. 15 – 60 minutes (depending on temperature).
