Frequently Asked Questions

Q1: How does the corner decoration work with matching plain mouldings?
The corner decoration is designed to connect two plain moulding strips at corners. At ceiling corners, accent wall corners, or waistline corners, two plain moulding strips are joined at a 90° angle, and the corner decoration covers the joint, creating a complete corner trim assembly.

Q2: Can the product be used on external corners? Does it support both internal and external corners?
The product is designed to accommodate both external corners (protruding corners) and internal corners (recessed corners). Select the appropriate mounting orientation based on the corner type. Some products are designed specifically for flat frame corners and are not suitable for wall corners.

Q3: How are the corner decorations installed?
Apply with specialized PU moulding adhesive or neutral mold-resistant construction adhesive. The substrate must be flat, dry, and free of grease. Apply adhesive evenly to the back of the corner decoration, press into place at the designated corner, ensuring alignment with adjacent plain moulding strips. Use painter's tape for temporary fixing until the adhesive is fully cured.

Q4: Are there visible gaps between the corner decoration and plain mouldings?
The corner decoration is sized to match the cross-section width of the matching plain moulding series. During installation, align the edges of the corner decoration with the ends of the plain moulding strips. Apply color-matched filler to the joint, allow to dry, and sand smooth for a clean, low-visibility joint.

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., Gold, black, antique colors), the surface accepts water-based or polyurethane paints. When painting carved areas, apply evenly to avoid paint accumulation in recessed details.

Q6: What plain moulding width is the 30×30cm corner decoration compatible with?
The 30×30cm corner decoration is compatible with plain mouldings having a face width not exceeding 30cm. Common compatible moulding widths range from 8cm to 12.8cm. Verify that the plain moulding face width matches the corner decoration specifications before purchasing.

Precautions

• Verify substrate flatness and corner angle (90° or as designed) before installation; Level corners with significant deviation prior to installation
• Storage requirements: Store flat on dry ground with stack height not exceeding 1 meter; Avoid heavy pressure that may damage carved details
• Cutting: Corner decorations typically require no cutting; Install as complete units. For custom sizing, use fine-tooth saw blades (tooth spacing ≤ 3mm) and apply color-matched paint to cut edges
• 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 corner decoration; Press firmly to ensure full contact with substrate and adjacent mouldings. Prevent adhesive from extruding into carved details
• Joint treatment: Fill gaps between corner decoration edges and plain moulding ends with filler, smooth with a damp cloth, and lightly sand with fine sandpaper after drying
• Inspect color and pattern consistency across multiple batches before installation
• Avoid cleaning carved surfaces with strong acids, strong alkalis, or organic solvents
• Handle carefully during transport; Carved details and edges are easily damaged. Avoid impacts
• If repainting, apply paint before installation for complete coverage of carved areas; Touch up joints after installation
