How to Decorate Prefabricated House Components
The decoration of prefabricated house components requires a comprehensive consideration of safety, functionality, and aesthetics, with a focus on the following aspects:
Plumbing and Electrical Renovation: Avoid Structural Damage, Thoroughly Update Systems
The plumbing and electrical renovation of prefabricated panel houses must strictly adhere to safety regulations. It is prohibited to cut horizontal grooves in the prefabricated panels, as horizontal cutting can weaken the structural strength of the panels, potentially leading to fractures and even affecting the safety of the rooms above. Lighting wires should be routed along the base of the walls or the floor to minimize direct damage to the panels. Additionally, the plumbing and electrical systems in prefabricated panel houses are often aged, and it is recommended to conduct a complete renovation, replacing old pipes and wires to ensure the safety of water and electricity usage. For example, use PPR pipes instead of cast iron pipes, and copper wires that meet national standards for electrical wiring, while reasonably planning the placement of sockets to meet the needs of modern appliances.
Wall Treatment: Conceal Cracks, Strengthen the Base Layer
Prefabricated panel walls are prone to cracking or porosity due to material characteristics, which can be addressed through full facade decoration or base layer treatment. If choosing to cover the walls, use built-in cabinets, bookshelves, or other storage spaces to conceal the walls, or employ a high-performance gypsum-based fiberboard with a metal cladding system for full coverage. This material has strong nail-holding power and high durability, allowing for the direct installation of wall lamps, paintings, and other decorations. If skimming is required, base layer treatment must be performed first: sand the uneven areas, remove dust, oil, and release agents; fill the joints between prefabricated panels with a special joint filler to prevent crack propagation; finally, apply water-resistant putty and sand it smooth to ensure coating adhesion.
Waterproofing and Insulation: Enhance Living Comfort
The floor waterproofing performance of prefabricated panel houses is poor, and waterproofing treatment must be carried out in wet areas such as kitchens and bathrooms. The floor should be coated with a flexible waterproof coating, with the wall height being at least 30 centimeters, and reaching 1.8 meters in the shower area. A closed-water test should be conducted to ensure no leakage. For insulation issues, waterproof insulation coatings can be applied to the walls, or insulation materials such as polystyrene boards or rock wool boards can be installed to reduce heat loss. For houses on the top floor, roof insulation treatment is also necessary, such as laying insulation bricks or reflective films to lower indoor temperatures in summer.
Sound Insulation and Structural Safety: Reduce Noise, Avoid Damage
Old prefabricated panel houses often have poor sound insulation, which can be improved by replacing windows. Choose double-glazed or vacuum-glazed windows and install weatherstripping to effectively block outdoor noise. If structural modifications to the house are required, such as removing non-load-bearing walls, consult a professional architect or structural engineer to ensure that the modifications do not affect the overall stability. For example, load-bearing walls between prefabricated panels should not be removed arbitrarily, as this may lead to floor collapse.
By implementing these measures, the functionality and living experience of prefabricated panel houses can be enhanced while ensuring safety.
