• Water Blocking Primer/Finish

    Nothing can ruin masonry more than moisture penetration – and nothing smells worse than a damp, musty environment. Fortunately, Water Blocking Primer/Finish prevents this from happening by making interior or exterior masonry walls impenetrable to moisture while reducing odors. The end result is a uniform, quality finish that reduces odors and blocks moisture.
