Surface preparation
It is essential that adequate preparation is carried out prior to the application of SpECtite PU-Flex Primer.
SpECtite PU-Flex Primer can be applied by brush and roller at the rate of 7 – 10 m²/litre. On very porous substrates it may be necessary to apply a second coat of primer if absorption is noted to be high. The primer/sealer must completely seal the floor or air release will cause bubbles to form in the subsequent layers of coatings.

Allow the primer to become touch dry.
SpECtite PU-Flex Primer is supplied in 5 and 20 litre packs with a coverage rate of 7 – 10 m²/litre.
