Wallpaper Quiz
Questions: 16 · 10 minutes
1. How does a half-drop match typically affect neighboring wallpaper strips?
Each strip overlaps half the width of the previous strip
The design on the next strip is offset by half a pattern repeat
The lower half of each strip is trimmed away before hanging
Alternate strips use a different color batch
2. What can happen if a seam roller is pressed too firmly on freshly hung wallpaper?
Adhesive may be squeezed out, or the surface may be marked or flattened
The wallpaper will automatically become easier to remove later
The wall primer will change into a stronger adhesive
The pattern repeat can permanently increase in length
3. Before soaking or steaming an entire wall to remove old wallpaper, what should you do first?
Identify the covering type and test the recommended removal method in a small area
Apply maximum steam immediately, whatever the wall substrate
Sand through the decorative face across the whole wall
Saturate every electrical fitting so the edges release evenly
4. A wall is 3.6 meters wide, and the usable width of each wallpaper strip is 0.6 meters. Ignoring openings, how many full-width strips span the wall?
5 strips
6 strips
7 strips
8 strips
5. What is a common purpose of hanging lining paper beneath decorative wallpaper?
To make pattern matching unnecessary at every seam
To eliminate the need to repair loose plaster or active damp
To convert every wallpaper into a peel-and-stick product
To create a more uniform base and help disguise minor surface irregularities
6. The label identifies a product as “paste-the-wall” wallpaper. What does that instruction mean?
Paste is applied only to the back of each dry strip
Paste is applied to the wall, and the dry strip is then positioned
Both the wall and paper must soak in paste before hanging
The wall needs no adhesive because the pattern activates with water
7. While hanging a strip, you notice a small trapped air pocket before the adhesive has set. What is the appropriate response?
Leave it untouched because all bubbles become permanent if pressed
Add another layer of wallpaper directly over the bubble
Gently smooth the air toward the nearest edge with a suitable tool
Drive a screw through the center to hold the paper flat
8. Two wallpaper estimates cover the same wall area, but one ignores a large pattern repeat. Which approach is more reliable?
Order only the exact measured area because repeats do not affect usage
Deduct every opening and then round the roll quantity down
Use the quantity left from a previous room of similar size
Allow for pattern-match waste and a reasonable reserve when calculating rolls
9. For a well-ventilated bathroom where occasional moisture and splashes are expected, which is generally the most suitable starting choice?
An uncoated, highly absorbent paper installed without checking its label
A delicate textile wallcovering selected only for its thickness
Any wallpaper described as removable, regardless of moisture guidance
A moisture-resistant vinyl or coated wallcovering approved for the setting
10. What distinguishes a straight-match wallpaper pattern?
Every second strip must be hung upside down
Matching motifs meet at the same height on adjacent strips
Each strip can be positioned without reference to its neighbor
The pattern aligns only at the ceiling and baseboard
11. Why should rolls for one room normally share the same batch or dye-lot number?
It reduces the chance of visible color variation between rolls
It guarantees that the pattern requires no matching
It shows that the rolls use identical adhesive instructions
It confirms that every roll contains the same number of meters
12. You are cutting a second strip of patterned wallpaper. What best helps preserve the match?
Cut it to the first strip’s length without checking the motifs
Turn it upside down regardless of the manufacturer’s directions
Align its motif with the first strip before marking and cutting allowances
Remove one full repeat from its length after it has been hung
13. You plan to hang wallpaper on newly finished drywall. What preparation is generally appropriate before hanging?
Polish the surface with wax to make repositioning easier
Leave the drywall bare so it absorbs the paste rapidly
Apply a wallcovering-compatible primer or sealer as directed
Coat the wall with ordinary cooking oil to limit absorption
14. Wallpaper must be trimmed around an electrical outlet. Which procedure best addresses electrical safety?
Leave the power on so the outlet can be tested during trimming
Cover the live outlet with wet wallpaper and trim it after the paste dries
Remove only the faceplate while keeping the circuit energized
Switch off the circuit at the breaker, verify it is off, then remove the cover and trim carefully
15. On a wallpaper specification, what does “pattern repeat” usually describe?
The vertical distance before the same part of the design appears again
The recommended overlap between neighboring strips
The time the adhesive must rest before hanging
The number of strips expected from every roll
16. Before hanging the first strip, why is a plumb line or level used?
To calculate how long the paste remains usable
To locate the exact center of every printed motif
To establish a true vertical guide because corners may not be straight
To determine whether two rolls came from the same dye lot
