Acrylitex Qwik Prep is a fast drying primer designed to equalize the porosity differences between the drywall face paper and joint compound in new drywall construction. Qwik Prep has excellent hide and is very white in color so you can easily see your new pattern when spraying texture. It provides a uniform surface that minimizes "joint banding" and "photographing" of the finish coat. VOC compliant.
