Finish TradesQuestion 224 of 700
Before hanging vinyl wallcovering on new, primed drywall, why is a wallcovering primer/sizing typically applied?
a.To add a decorative color under the seams
b.To provide a uniform, sealed surface with good adhesion and allow future strippability
c.To eliminate the need to smooth the wall
d.To make the wall permanently waterproof
Explanation
A wallcovering primer (sizing) seals the surface, evens out porosity for uniform adhesive grab, and lets the paper be stripped later without tearing the drywall face. It is not a decorative layer, does not replace surface prep, and does not make the wall waterproof.
