WeberSpec Smooth Rapid Floor
Primer/ Bonding coat
The substrate should be vacuum cleaned, prepared and primed with weberfloor 4716 primer, according to the manufacturer's instructions (e.g. mixing recommendations). Priming improves the screed’s adhesion to the substrate and prevents the formation of air bubbles and dewatering of the screed. Dry and very porous substrates (cast-in-situ concrete floors) may need to be treated twice. If the screed is applied in more than one layer, each layer must be primed.
