Roman PRO-999 Rx-35 Interior Drywall Repair and Sealer Primer - 1 gal

ROMAN’s PRO-999 Rx-35 Primer is a professional-grade, water-based solution formulated to seal and prepare porous, damaged, or textured surfaces for wallpaper installation. It’s ideal for drywall, skim coats, spackling, popcorn ceilings, contractor’s flat paint, and even surfaces with residual wallpaper paste. The primer dries to a clear matte finish with a slight residual tack to improve wallpaper adhesion and ensure long-lasting results.

Its no-run, low-odor formula makes application quick and clean, while its low VOC content (under 25 g/L) supports healthier indoor air quality. Whether you're covering newly patched drywall or prepping a textured wall, PRO-999 Rx-35 simplifies the process and enhances final results.
