How to Decorate the Roof of a Prefabricated Slab House

The decoration of the roof of a prefabricated slab house should be selected based on structural characteristics, functional requirements, and budget. Common methods include leveling treatment, concealed wiring layout, reinforcement treatment, and targeted decoration design.

1. Leveling Treatment: Addressing Surface Irregularities on the Roof

If there are irregularities on the roof surface, the treatment method should be selected based on the size of the gaps:

• Gaps less than 5 millimeters: Gypsum can be used directly for leveling, with a cost of approximately 30 yuan per square meter and a construction thickness not exceeding 3 millimeters. This method is suitable for roofs with minor irregularities, enabling quick surface leveling at a low cost.
• Gaps between 5-20 millimeters or exceeding 20 millimeters: A suspended ceiling should be used to resolve the issue. Large gaps may affect subsequent decoration effects, and a suspended ceiling can conceal defects and enhance overall aesthetics.

2. Concealed Wiring Layout: Leveraging the Structural Advantages of Prefabricated Slabs

Prefabricated slabs typically contain hollow conduits internally, which can be reasonably utilized for concealed wiring layout:

• Thread shielded wires through the hollow conduits of the prefabricated slabs to avoid cutting grooves on the roof surface and reduce damage to structural strength.
• This method requires advance planning of circuit routes to ensure reasonable wire distribution and compliance with safety regulations, especially suitable for decoration scenarios requiring concealed wiring.

3. Reinforcement Treatment: Repairing Structural Damage

If the prefabricated slabs exhibit issues such as pulling apart, damage, or movement, reinforcement treatment should be prioritized:

• Prefabricated slabs pulling apart or damaged: Fill the gaps with cement mortar and thicken the steel bars to enhance structural stability.
• Roof movement: Use iron pipe supports or add brick piers for fixation to prevent further displacement.
• Reinforcement treatment is a prerequisite for decoration, ensuring the roof structure is safe before proceeding with surface decoration.

4. Decoration Scheme Selection: Balancing Functionality and Aesthetics

Choose an appropriate decoration method based on needs:

• Partial suspended ceiling: Install a narrow-edged suspended ceiling (width 30-40 centimeters, drop 10-15 centimeters) in areas where concealed piping or air conditioning vents are needed. This scheme offers high cost-effectiveness, retains most of the ceiling height, and is suitable for small apartments or rooms with low ceiling heights.
• Gypsum line decoration: Apply gypsum lines at the junction between the ceiling and walls, with options for flat or vintage styles. This method is low-cost and offers excellent decorative effects, enhancing spatial layering and suitable for simple or European-style decorations.
• Wooden suspended ceiling: Although not elaborated in detail, it can be considered as an option. Wooden materials create a warm and natural atmosphere but require attention to moisture-proofing, suitable for dry environments.

Before decoration, conduct a comprehensive inspection of the roof structure to ensure there are no safety hazards before proceeding with construction, and select the most appropriate scheme based on actual needs.
