Decoration Process for Prefabricated Houses
The decoration process for prefabricated houses can be divided into the following steps:
1. Preliminary Preparation
Clarify decoration requirements, including budget, style (such as modern simplicity, Nordic style), and functional needs (such as open kitchens, smart home systems); choose a decoration mode (self-procurement, partial-procurement, or full-package); conduct precise measurements to confirm details like water and electricity points, storage spaces, etc.; sign a contract that specifies the project duration, material brands (e.g., specifying 'flame-retardant BV wire' for electrical wires), payment ratios, and additional terms (such as daily compensation of 0.1% of the total contract amount for delays).
2. Demolition and Reconstruction Phase
Obtain property approval before demolishing non-load-bearing walls to avoid structural damage; prioritize lightweight steel keels (for moisture resistance) or red bricks (for good sound insulation) when building new walls, paying attention to sound insulation treatment; promptly clear debris after demolition and reconstruction to maintain a clean site.
3. Plumbing and Electrical Renovation
Locate positions for sockets, switches, light fixtures, and water pipes, following the principle of 'water pipes on the ceiling, electrical wires on the floor'; when trenching and wiring, use PPR pipes for water and flame-retardant wires for electricity, wrapping aluminum foil at intersections of strong and weak currents to prevent interference; conduct pressure tests (water pipe pressure at 0.8MPa for 30 minutes without leakage) and power-on tests during acceptance, and take photos to document the pipeline layout.
4. Waterproofing and Tiling
Apply waterproofing on bathroom walls up to 1.8 meters high (or at least 1.5 meters), using waterproof materials with a color different from the wall to avoid missed applications; conduct a 48-hour closed-water test to confirm no leakage before tiling; wall tiles over floor tiles are more moisture-resistant; leave a 2-3mm gap between tiles and use a hollow drum hammer to check for a hollow rate of ≤5%; ensure floor leveling error is ≤3mm (when laying wooden floors).
5. Carpentry Phase
Use lightweight steel keels for ceiling moisture resistance and make V-shaped grooves at gypsum board joints to prevent cracking; when customizing cabinets or opting for whole-house customization, prioritize ENF-grade or E0-grade environmentally friendly panels; design background walls to be simple and timeless, avoiding complex shapes.
6. Painting Work
The wall treatment process involves gypsum leveling → two coats of putty → sanding → one coat of primer → two coats of finish paint; close doors and windows during air-drying to prevent cracking, and choose premium-grade latex paint; conduct a small-area color test before full application to confirm the color is correct.
7. Installation Phase
Install doors, floors, cabinets, and bathrooms in sequence; reserve sockets when installing appliances (such as air conditioners, range hoods); use dual-control designs for light switches (in bedrooms) or switches with sockets (in kitchens) to enhance convenience.
8. Acceptance and Soft Furnishings
Conduct phased acceptance (plumbing → waterproofing → tiles → painting → overall), focusing on checking water and electricity lines, waterproofing effectiveness, and tile hollows; ventilate for more than 3 months and test for formaldehyde (standard ≤0.08mg/m³); finally, arrange furniture, curtains, and other soft furnishings to complete the overall decoration.
