2024 COMPLETE 600 QUESTIONS
AND CORRECT ANSWERS
Advantages of Gypsum Drywall ✔✔✔✔✔✔ANSWER➖low install cost, quick &
easy installation, fire resistance, sound control capability, easy availability,
versatility, ease of finishing & decorating, ease of installation of doors/other
openings
Gypsum Drywall Edges ✔✔✔✔✔✔ANSWER➖Tapered: Most common; tapered
on face side along the long dimension of the panel & square edges at the end;
allows for application of reinforcing tape & joint compound without causing
bulges at joints
Square: used where appearance is NOT a factor, for basic layers of 2-layer
applications & for veneer plaster work
Levels of Gypsum Drywall ✔✔✔✔✔✔ANSWER➖1: plenums above ceilings &
other areas not normally open to view (tape embedded in joint compound w/
surface free of excess compound
2. water resistant backing board (all joints & angles have tape embedded in joint &
one separate coat of compound
3. heavy or medium textured finishes/heavy-grade wallcovering ( 2 coats of
compound)
4. Light textured or wallcoverings & where economy is concerned (3 layers)
,5. all paints, severe lighting conditions (4 layers)
Studs are spaced how far apart? ✔✔✔✔✔✔ANSWER➖residential: 16" O.C.
commercial: 24" O.C.
Slip Joint ✔✔✔✔✔✔ANSWER➖prevent wall from being damaged if the
structural floor deflects
Plaster Construction ✔✔✔✔✔✔ANSWER➖1. Scratch Coat
2. Brown Coat (level surface)
3. Finish Coat (Leveling & desired texture)
*Add Trim
Masonry Block Dimensions ✔✔✔✔✔✔ANSWER➖8"x8"x16" (-3/8" for mortar
joints)
Demountable Partitions ✔✔✔✔✔✔ANSWER➖Consists of a system of individual
components that can be quickly assembled, disassembled & reused with nearly
total salvageability
consists of floor runners, ceiling runners, stud sections with clips to hold panels, &
prefinished gyp. wallboard panels
uses aluminum for framing
,Definition: Hinges ✔✔✔✔✔✔ANSWER➖Consist of 2 leaves with an odd
number of knuckles on one leaf and an even number of knuckles on the other
knuckles are attached with a pin
knuckle + pin = barrel (finished with tip)
Types of Hinge Tips ✔✔✔✔✔✔ANSWER➖-flat button (most common; typical)
-hospital
-oval head (typical)
-steeple
-flush
Butt Hinge ✔✔✔✔✔✔ANSWER➖MOST COMMON; has both leaves fully
mortised into the frame and the edge of the door so the hinge is flush with the
surface of the frame and door
raised barrel hinge ✔✔✔✔✔✔ANSWER➖used when there is not room for the
barrel to extend past the door trim; OFFSET to allow one leaf to be mortised into
the frame (kind of has an L shape on each side)
swing clear hinges ✔✔✔✔✔✔ANSWER➖has a special shape that allows the
door to swing 90 degrees or 95 degrees so the full opening of the doorway is
available
, definition: latches & locksets ✔✔✔✔✔✔ANSWER➖device to operate a door,
hold in position & lock it
latchset ✔✔✔✔✔✔ANSWER➖ONLY holds door in place; NO lock (i.e.
restroom partitions)
lockset ✔✔✔✔✔✔ANSWER➖special mechanism that allows the door to be
locked with a KEY or THUMBTURN
mortise lockset ✔✔✔✔✔✔ANSWER➖installed in rectangular area cut out of
door; more SECURE than cylindrical and offers wider variety of locking options
cylindrical ✔✔✔✔✔✔ANSWER➖most common; simple to install in holes drilled
into door, relatively inexpensive, most common in residential (like doors in home
bedroom)
pre-assembled ✔✔✔✔✔✔ANSWER➖rectangular box that fits within a notch cut
in the edge of the door; easier to install than mortise; door knob OR lever can be
used
center hung pivot ✔✔✔✔✔✔ANSWER➖allow door to swing in either direction
& is completely concealed
pivots CANNOT be used with a door stop (instead use a flexible strip of wool pile
or synthetic stripping can be rabbeted into the edge of the door) on the same side of
the door with both jambs because it makes it difficult to seal the door against sound
or light transmission on the hinge and strike sides
