How to Decorate Prefabricated House Components Well
The decoration of prefabricated house components requires comprehensive planning in multiple aspects, including water and electricity renovation, thermal insulation, sound insulation, crack repair, waterproofing, wall treatment, and structural protection. The specific key points are as follows:
1. Water and electricity renovation: Avoid risks and conduct a thorough upgrade
Prefabricated panels are hollow structures. It is strictly prohibited to cut horizontal grooves in the walls (the groove depth is usually 5 centimeters) to avoid damaging the structural stability. The water and electricity systems in old prefabricated houses may have problems such as aging wires and unreasonable layouts, requiring a thorough renovation: Replace aging pipelines, optimize circuit layouts to ensure electrical safety; re-plan the direction of water pipes to avoid leakage risks. After the renovation, pressure tests and circuit inspections should be carried out to ensure system reliability.
2. Thermal insulation: Improve living comfort
Prefabricated houses have poor thermal insulation performance, easily losing heat in winter and absorbing heat in summer. Thermal insulation coatings can be applied to the walls or thermal insulation panels (such as polystyrene panels and rock wool panels) can be installed to reduce heat transfer. For residents on the top floor, roof insulation treatment is necessary, such as laying insulation films, building insulation layers, or planting greenery to reduce indoor temperature fluctuations.
3. Sound insulation: Block noise transmission
Old prefabricated houses have weak sound insulation effects. Sound insulation should be addressed from the windows and ceilings: Replace windows with double-glazed or vacuum-glazed windows and use sealing strips to close gaps. Adopt a professional sound insulation ceiling system (such as clip-in keels + sound insulation cotton), which not only reduces noise from the upstairs but also supports the design without main lights. Sound-absorbing panels or soft packs can be installed on the walls to further reduce noise reflection.
4. Solve the problem of plaster layer cracking: Combine concealment and coverage
Plaster layer cracking is a common problem in prefabricated houses. Defects can be hidden through 'full facade decoration': Use customized cabinets and bookshelves to cover cracked areas. For blank walls, use high-performance gypsum-based fiberboard + metal cladding system for full coverage. Its high nail-holding strength can fix decorations (such as wall lamps and oil paintings) while solving cracking problems.
5. Waterproofing: Strict construction in key areas
The prefabricated floor panels are prone to structural damage due to water seepage. Kitchen, bathroom, and other damp areas require key waterproofing: Apply flexible waterproof coatings (such as polyurethane) on the ground, and the waterproof height on the walls should be no less than 1.8 meters. Strengthen the treatment around pipe roots and floor drains with sealants. After a 48-hour closed-water test without leakage, the next construction step can be carried out.
6. Wall skimming: Key to base layer treatment
Although the surface of prefabricated panels is flat, there are problems such as pores and release agent residues. Direct skimming can easily lead to hollowing and cracking. Before construction, thoroughly clean the surface and polish uneven areas. Fill the joints between prefabricated panels (using special joint fillers). Apply an interface agent to enhance adhesion. Skim water-resistant putty in two coats, and polish it flat after each coat dries.
7. Structural protection: Avoid arbitrary modifications
The load-bearing capacity of prefabricated houses is limited. During decoration, it is strictly prohibited to remove load-bearing walls or beams and columns. If non-load-bearing structures (such as partitions) need to be modified, consult a professional engineer to ensure the safety and feasibility of the plan.
