Frequently Asked Questions

Q1: Does the medallion have a pre-cut central lamp hole?
Depending on the specific style, the medallion may have a pre-cut central hole (for pendant light and flush-mount light wire access) or be solid (for decorative purposes without fixture installation). Confirm the required style and fixture installation requirements before purchasing.

Q2: How are the medallions installed?
Apply with specialized PU moulding adhesive or secure with screws. The substrate (ceiling gypsum board or wood panel) must be flat, dry, and free of grease. Apply adhesive evenly to the back of the medallion, press into place, ensuring full contact with the ceiling surface. For large medallions, increase adhesive application and add screw fixing points.

Q3: Can the product be used in humid environments (bathroom or kitchen ceilings)?
Yes. PU material does not absorb water, does not support mold growth, and does not expand, making it suitable for ceiling decoration in humid environments such as bathrooms and kitchens. Seal the back and edges to prevent moisture penetration.

Q4: Does the medallion require painting after installation?
The product comes pre-primed or with a white finish (depending on product series) and is ready to use after installation. For color changes (e.G., Gold, black, wood grain), the surface accepts water-based or polyurethane paints. When painting large medallions, apply evenly to avoid drips or runs.

Q5: What size light fixture is compatible with the 77×57.5cm medallion?
This medallion is suitable for light fixtures with a base diameter or width not exceeding 50cm, such as living room main lights and dining room chandeliers. The fixture base should be fully covered by the medallion; The fixture base dimensions should be smaller than the medallion's inner dimensions or central hole size.

Q6: Can the medallion be cut?
The medallion is an integrally molded product and generally should not be cut. If size adjustment is necessary, use a fine-tooth saw blade (tooth spacing ≤ 3mm), though this will compromise the smooth edge profile. It is recommended to purchase the correct size.

Precautions

• Verify that the ceiling surface is flat, dry, and free of grease before installation; Height difference ≤ 3mm when measured with a 2-meter straightedge
• Storage requirements: Store flat on dry ground with stack height not exceeding 1 meter; Avoid heavy pressure that may cause deformation or edge damage
• Before installation, check whether the central hole (if present) aligns with the fixture wire access point
• Recommended installation ambient temperature: 5°C to 35°C. Avoid low temperatures that may slow adhesive curing
• Apply adhesive evenly to the back of the medallion. For large medallions, use a combination of spot and strip adhesive application. Press firmly to ensure full contact with the ceiling surface without hollow spots
• For large medallions, use screws for additional fixing. Use stainless steel or galvanized screws to prevent rust contamination. Countersink screw heads below the medallion surface and cover with filler
• Inspect color consistency across multiple batches before installation
• Avoid cleaning with strong acids, strong alkalis, or organic solvents
• Handle carefully during transport; Edges and corners are easily damaged. Avoid impacts
• If repainting, apply paint before installation; Touch up screw holes and joint areas after installation
• Two-person handling is recommended for large medallions during transport and installation to prevent deformation or breakage from single-person handling
