how many levels of gyp finish levels are there?
6
gyp finish level 0 and where used
Unfinished. Bare drywall
Temporary construction or when the final decoration has not yet been determined
No taping, finishing or corner beads.
gyp finish level 1 and where used
Taped but without finishing over with joint compound
Used in plenum areas, attics, building service corridors and areas concealed from public view
gyp finish level 2 and where used
Taped with a thin coating of joint compound over all joints and interior angles, fasteners and accessories
Used with water-resistant gypsum as a substrate for tile, or in garages, warehouse storage or other back of house areas where a finished surface appearance is not important.
gyp finish level 3 and where used
Two coats of joint compound applied over joints, and interior angles, fasteners and accessories
Used in areas which will receive heavy texture (spray or hand applied) finishes before final painting, or where commercial-grade (heavy duty) wallcoverings will be used
gyp finish level 4 and where used
Two coats of joint compound over joints and interior angles, with three coats of joint compound over fasteners
Used when the finish decoration will be residential grade (light duty) wall coverings, flat paints or light texture.
gyp finish level 5 and where used
Like level 4 with an additional thin skim coat of joint compound trowel applied to the entire surface, leaving a film or skim coating of joint compound completely covering the paper
Required where gloss, semigloss or enamel are specified, or when flat joints are specified over an untextured surface, or for used in critical lighting conditions
