Wallpaper
:
This wall detector functions normally on walls
covered with wallpaper or fabric, unless the materials are
metallic foil, contain metallic fibers, or are still wet after
application. Wallpaper may need to dry for several weeks
after application.
Freshly painted walls:
May take one week or longer to dry
after application
Lath & plaster:
Due to irregularities in plaster thickness, it
is difficult for this wall detector to locate studs in Stud
modes. Change to Metal Scan mode to locate the nail
heads holding wood lath to the studs. If the plaster has
metal mesh reinforcement, the wall detector may be unable
to detect through that material.
Extremely textured walls or acoustic ceilings:
When
scanning a ceiling or wall with an uneven surface, place thin
cardboard on the surface to be scanned and scan over the
cardboard in Deep mode. If irregular scanning results are
received, switch to Metal Scan mode to locate nails or
drywall screws that line up vertically where a stud or joist is
positioned.
Wood flooring, subflooring, or gypsum drywall over
plywood sheathing:
Use Deep mode and move the tool
slowly. The Signal Strength Indicator may only display 1 or
2 bars when the tool locates a stud through thick surfaces.
