Wallpaper Hanging Honor

Vocational Activities

Requirements

1. Describe the proper preparation of a wall for hanging wallpaper.

   Answer: Clean the wall, removing dust, grease, and mold. Sand rough spots, fill holes and cracks with joint compound (wait 24h to dry and sand). Apply primer or sealing paint if the wall is very porous or colored. Check that it is completely dry. Mark a reference vertical plumb line with a plumb bob from the ceiling. — Proper preparation determines the final result. Dirt prevents the adhesive from sticking. Holes show through the paper. Very colored walls can stain light-colored paper (use light paint first). The sealer evens out the porosity. The plumb bob ensures perfect alignment. Ideal temperature: 18-22°C; too cold slows drying, too hot creates bubbles. Good preparation saves time and materials and produces a durable, professional-quality finish.

2. Explain how to fix wallpaper, describing at least 2 methods.

   Answer: 1) Traditional paste (non-adhesive paper): specific paste (powdered or ready-made) is applied with a brush or roller on the back of the paper, left to hydrate for 5-10 minutes, positioned on the wall, and smoothed with a plastic spatula from the center to the edges. 2) Self-adhesive paper (peel-and-stick): it has dry adhesive ready on the back. — The two methods have distinct characteristics. Traditional paste is stronger and more durable but requires preparation. Self-adhesive is practical and removable, ideal for rented apartments (does not damage the wall). There is also the paste-the-wall method (paste on the wall, not on the paper), popular in Europe. Vinyl has an extra-resistant version (bathrooms). For beginners, self-adhesive is easier; professionals prefer traditional paste for its proven durability.

3. Using a method mentioned in the previous question, hang wallpaper on at least 2 walls of a house (bedroom, living room, kitchen, etc.).

   Answer: Measure the walls and calculate the rolls needed (a 10% extra margin). Mark the initial vertical plumb line. Cut the first strip with 5cm to spare at the top and bottom. Apply adhesive according to the chosen method (traditional or self-adhesive). Hang it from top to bottom, aligning with the plumb line. Smooth it with a spatula from the center to the edges, expelling bubbles. — The application requires patience and technique. Common mistakes: bubbles (resolved by pricking with a needle and smoothing), edges peeling off (re-apply adhesive at the tip), misalignment (impossible to correct, must be redone). Working in pairs helps a lot (one holds, the other smooths). It is common in bedrooms and living rooms. Bathrooms and kitchens call for moisture-resistant paper. Visiting stores like Leroy Merlin or hiring a professional for complex walls is a good option.

4. Demonstrate how to align a pattern well on the wall being worked on.

   Answer: Identify the type of pattern match on the packaging: 1) Straight (RM): the pattern aligns horizontally without waste; 2) Offset/Drop (HM): each strip starts half the pattern higher, creating an alternating design; 3) Random/Free (FM): no matching needed (texture, simple stripes). — Correct pattern matching is what distinguishes amateur work from professional. Straight match is the simplest; drop match requires calculation (it usually wastes 5-10% more paper); free match is the most economical. Always check the roll label (RM/HM/FM) to plan correctly. Mistakes at this step are costly since each meter of paper costs between R$30-200. Taking the time to align well ensures a harmonious look across the whole wall.

5. Use your creativity by designing some wallpaper combinations for the following:
   • Living room
   • Kitchen
   • Bathroom
   • Bedroom
   • Game room
   • Church

   Answer: Living room: papers with neutral textures (linen, sand) or discreet patterns to welcome guests. Kitchen: cheerful washable patterns (fruits, colorful stripes, resistant vinyl). Bathroom: paper made for moisture with light colors and geometric patterns. Bedroom: soft relaxing tones (light blue, sage green, discreet floral). — Each room has its own purpose and atmosphere. The living room receives guests (the impression matters). The kitchen needs to be practical (vinyl is better). The bathroom calls for moisture resistance. The bedroom values comfort and rest. A game room can be bold in creativity and energy. A church requires formality and respect. Colors influence mood: red energizes, blue calms, green harmonizes. Also remember the natural and artificial lighting of the room.
