Width 12.8cm Plain PU Mouldings & Cornices

Key Advantages

• Face width of 12.8cm, suitable for primary waistlines and wide trim applications
• Smooth flat design without patterns; Compatible with various interior styles
• PU material density lower than gypsum or wood mouldings, reducing weight for easier handling and installation
• Moisture and corrosion resistance: Non-absorbent, non-expanding, non-rotting; Suitable for humid environments
• Compression resistance and dimensional stability: Maintains flatness after installation without deformation
• Smooth surface: Ready to install without on-site sanding

Frequently Asked Questions

Q1: What are the main application differences between the 12.8cm wide moulding and narrow mouldings (e.G., 2cm, 8.5cm)?
The 12.8cm wide moulding is suitable for primary wall waistlines, wide trim, and large-area decorative applications, providing strong visual presence as the main wall decoration. Narrow mouldings are suitable for fine trim, partial accents, and wall grid lines. The two can be combined in the same space to create a hierarchical decorative composition.

Q2: How are the mouldings installed? What auxiliary materials are required?
Apply with specialized PU moulding adhesive or neutral mold-resistant construction adhesive. The substrate must be flat, dry, and free of grease, with height difference not exceeding 3mm when measured with a 2-meter straightedge. Due to the larger contact area of wide mouldings, apply adhesive evenly across the entire back surface, press firmly to ensure full contact with the substrate. Fill joints with color-matched filler.

Q3: Can the product be used in bathrooms, kitchens, and other humid environments?
Yes. PU material does not absorb water, does not develop mold, does not expand, and does not rot, making it suitable for high-humidity environments. Seal the back and joints to prevent moisture penetration between the moulding and the wall.

Q4: How are corners handled with wide mouldings?
For both external and internal corners, use 45° miter cuts. Cut the moulding ends at 45° using a miter saw or utility knife, apply adhesive, and join. Due to the wider profile, ensure miter cuts are clean and accurate to avoid visible gaps at the joint. Alternatively, use butt joints with one end cut flat and overlapped over the other, filling the joint with filler.

Q5: Does the product 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., Gray, black, wood grain, metallic colors), the surface accepts water-based or polyurethane paints with good adhesion. When painting wide mouldings, apply evenly to avoid drips or runs.

Q6: How is flatness maintained during installation of wide mouldings?
Ensure substrate flatness meets requirements before installation. Apply adhesive evenly across the entire back of the moulding, use a level during pressing to ensure the moulding is on the same plane. For continuous installations longer than 2 meters, apply in sections and use painter's tape for temporary fixing until the adhesive is fully cured.

Precautions

• Verify substrate flatness before installation: height difference ≤ 3mm when measured with a 2-meter straightedge. Substrate must be dry, free of grease, and free of loose dust
• Storage requirements: Store flat on dry ground with stack height not exceeding 1 meter; Avoid heavy pressure that may cause deformation. Ensure the storage surface is flat for 12.8cm wide mouldings
• Use fine-tooth saw blades (tooth spacing ≤ 3mm) or miter saws when cutting; Wear safety goggles. Cutting wide mouldings manually with a utility knife is challenging; Power tools are recommended
• Apply color-matched paint or filler to cut edges to maintain consistent appearance
• Recommended installation ambient temperature: 5°C to 35°C. Avoid low temperatures that may slow adhesive curing
• Apply adhesive evenly across the entire back of the moulding; Ensure full contact with the substrate without hollow spots
• Joint treatment: Apply filler to butt joints, smooth with a damp cloth, and lightly sand with fine sandpaper after drying. Position joints in areas where they are less likely to be directly in the line of sight
• Inspect color consistency across multiple batches before large-scale installation
• Avoid cleaning with strong acids, strong alkalis, or organic solvents
• Handle carefully during transport to prevent edge and corner damage or surface scratches
• For vertical wall installation of wide mouldings, ensure adequate support before adhesive cures; Use temporary support rods or painter's tape for fixing
