Hypo Drywall Surface Primer

A fast drying, water-based interior wall surface preparation primer formulated specifically to equalize the surface porosity between the gypsum panel face and the finished joint Compound. To reduce toxic emissions and control out-gassing, this product has an extremely low VOC and does not contain mildewcide or fungicide. Its higher solid content leaves a higher film build, which can help hide wall imperfections.  This product is recommended for use where level five gypsum finish board is required. (Available in 1 and 5 gallon containers.)
