Sample FL Gypsum Drywall Practice Questions

Try these sample questions to test your FL Gypsum Drywall exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which additive gives Type X gypsum board its enhanced fire-resistance rating?

A.Glass fibers and other core additives such as vermiculite

B.Portland cement blended into the gypsum core

C.Asbestos fibers woven through the core

D.Polyurethane foam laminated to the back

Explanation: Type X gypsum board is formulated with glass fibers and other additives (such as vermiculite) in the core. These hold the calcined gypsum in place under heat so the board maintains integrity longer in a fire-rated assembly. Regular gypsum board lacks this reinforcement.

2Per GA-214, a Level 1 finish requires which treatment?

A.Tape embedded in joint compound at joints and interior angles only

B.Two separate coats of compound over all joints and accessories

C.A full skim coat applied over the entire surface

D.No taping, finishing, or accessories - board merely fastened in place

Explanation: Level 1 embeds tape in compound over joints and interior angles and is used in concealed areas such as above ceilings or behind permanent assemblies. It is the lowest finish level that includes taping. Level 0 means no finish work at all.

3Which screw type is correct for fastening gypsum board to metal studs?

A.Fine-thread bugle-head self-drilling screw

B.Coarse-thread bugle-head wood screw

C.Fine-thread flat-head machine screw

D.Coarse-thread pan-head screw

Explanation: Fine-thread (Type S) bugle-head screws are designed to drill into and hold thin metal studs without stripping. The bugle head seats into the paper without over-penetrating. Coarse thread is for wood framing, where fibers need to be gripped.

4Where is green-board gypsum panel an appropriate use?

A.As a moisture-resistant base behind ceramic tile in indirect-moisture areas

B.As the board in a 1-hour fire-rated wall assembly

C.As exterior roof sheathing exposed directly to weather

D.On a corridor ceiling where an STC 50 rating is required

Explanation: Green board has a moisture-resistant core and paper suited for humid or indirect-moisture areas such as bathroom walls behind tile. It is not a fire-rated board, not for direct weather exposure, and acoustic performance depends on the full assembly, not the green board itself.

5A room is 10 ft by 12 ft with 8 ft walls and no openings. What total board area must be covered for the walls only (one layer)?

A.352 sq ft

B.256 sq ft

C.192 sq ft

D.320 sq ft

Explanation: Wall perimeter is 2(10 + 12) = 44 ft, and wall area is 44 x 8 = 352 sq ft. Each 4x8 board covers 32 sq ft, so this wall surface would require 11 boards. Openings would reduce the area, but the question specifies none.

6Which board is typically required to achieve a 1-hour fire-rated wood-framed wall assembly per listed UL designs?

A.5/8 in. Type X gypsum board

B.1/2 in. regular gypsum board

C.1/4 in. flexible gypsum board

D.1/2 in. water-resistant green board

Explanation: Most listed 1-hour wood-framed wall assemblies use 5/8 in. Type X gypsum board because its glass-fiber-reinforced core maintains integrity under fire for the rated period. Regular, flexible, and green boards are not fire-rated products.

7What does GA-216 specify?

A.Application and finishing of gypsum panel products

B.Levels of gypsum board finish (0 through 5)

C.Installation of metal stud framing

D.Suspended acoustical ceiling grid systems

Explanation: GA-216 is the Gypsum Association standard for the application and finishing of gypsum panel products, covering fastener spacing, joint treatment, and installation practices. It is one of the approved references on the CILB exam.

8How do fastener spacings typically compare between walls and ceilings per GA-216?

A.Ceilings require closer fastener spacing than walls

B.Walls require closer spacing than ceilings

C.Both use identical spacing regardless of orientation

D.Spacing depends only on board thickness, not orientation

Explanation: Ceiling board is loaded by gravity and can sag, so GA-216 calls for closer fastener spacing on ceilings than on walls for the same board. Orientation is a controlling factor along with board thickness and framing spacing.

9On ceiling joists spaced 24 in. o.c., which board thickness is the minimum recommended to resist sag without back-blocking?

A.5/8 in.

B.1/4 in.

C.3/8 in.

D.1/2 in.

Explanation: Half-inch board on 24 in. o.c. ceilings tends to sag between joists; 5/8 in. board is the recommended minimum for that spacing to resist sag. Thinner boards are used for overlays or curves, not for wide-ceiling spans.

10A 4x8 sheet is applied to wall studs spaced 16 in. o.c. with screws spaced 8 in. o.c. along each stud, including the two edge studs. How many screws fasten the board?

A.52

B.48

C.39

D.64

Explanation: A 48-in.-wide board on 16 in. o.c. studs lands on 4 studs (0, 16, 32, 48 in.). Over 96 in. of height at 8 in. o.c. there are 13 screw positions per stud (96/8 + 1). Four studs times 13 screws equals 52 screws.

About the FL Gypsum Drywall Exam

Florida Certified Gypsum Drywall Specialty Contractor trade knowledge exam covers gypsum and gypsum wallboard installation (board types, fasteners, spacing, tools, estimating), taping and texturing (joint compound, tape, GA-214 finish levels, texture types), metal stud walls and ceiling grid systems (stud gauge and spacing, runner track, suspended acoustical ceilings, door framing, layout), and special applications (curves, fire and sound control, exterior sheathing, OSHA safety). The exam tests knowledge of GA-216, GA-214, ASTM C840, ASTM C1007, ASTM C635, FBC, and OSHA 29 CFR 1926.

FL Gypsum Drywall Study Tips from Top Performers

1Tab and highlight GA-216 (Application and Finishing of Gypsum Panel Products) and GA-214 (Levels of Finish) before exam day; fastener spacing tables and finish level definitions are heavily tested.

2Know the board types cold: Type X for fire ratings, green/paperless for moisture and mold, cement board for wet tile substrates, glass-mat sheathing for exterior use, and 1/4 in. flexible for curves.

3Practice drywall math: board area (4x8 = 32 sq ft), room wall and ceiling board counts, fastener counts per board, stud counts at 16 in. o.c. (length/16 + 1), and compound coverage per gallon.

4Master metal framing: 25 gauge for non-load-bearing partitions, 20 gauge for taller or cabinet walls, ASTM C1007 for installation, runner track top and bottom, and ASTM C635/CISCA for ceiling grid.

5Review OSHA 29 CFR 1926: 6 ft fall protection trigger, GFCI on temporary 120V receptacles, ladder 1:4 ratio, scaffold load requirements, and lead RRP rules for pre-1978 paint disturbance.
