Prep Tex is a ready mixed drywall texture base coat designed to improve the quality of the drywall finish. It is recommended for use prior to the application of texture or decoration to minimize texture variation between finished gypsum surface and gypsum face paper. It is not, and should not be considered as, a "sealer," or an architectural coating.
There is, and has always been, a surface texture differential between the drywall face paper and joint cements used for concealment of joints, fasteners and trims. Even with the best drywall finishing techniques, those surface differentials may be visible after texture and painting. The likelihood of this problem occurring is greatly increased when severe side lighting, gloss finishes or light textures are present. Prep-Tex, when applied over a properly finished drywall installation, provides a surface with minimal differential, ready for decoration.
Prep Tex provides a smooth, sandable surface, eliminating problems often caused by porosity variations between finished joints and untreated gypsum wallboard paper.
Any drywall surface to be decorated with gloss paints, or subject to severe lighting conditions, should be treated. Surfaces to be finished smooth, with no texture, whether flat or gloss finish is specified, should likewise be treated. This product is also recommended for use prior to application of texture to minimize texture pattern variation. Made in USA.
