HeliPrimer WB is an aqueous dispersion of an acrylic copolymer containing coalescents and biocide.
The primer is used when coatings are applied to porous substrates. It can be used as a pre-sealer and as a curing aid for concrete repair mortar.
HeliPrimer WB is supplied ready for application although containers should be shaken immediately prior to use. The primer can be applied by brush, roller or, on large uninterrupted areas, by spray. Any coating should be applied when the WB Primer is touch-dry.
