Frequently Asked Questions

Q1: What are the main differences between the 15×15cm small corner decoration and the 30×30cm corner decoration?
The 15×15cm small size is designed specifically for narrow-profile mouldings (face width up to 15cm) and small-space applications. The 30×30cm large size is designed for wide-profile mouldings and large wall areas, such as primary waistlines. The two sizes are not interchangeable; Select based on moulding width and space scale.

Q2: How does the corner decoration work with matching narrow plain mouldings?
Join two narrow plain moulding strips at a 90° angle at the corner, and cover the joint with the corner decoration. The 15×15cm size is compatible with narrow mouldings up to 8cm face width. After installation, the edges of the corner decoration align with the ends of the moulding strips, creating a complete corner trim assembly.

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

Q4: 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.

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, the surface accepts water-based or polyurethane paints. For the 15×15cm small corner decoration, use a small brush to avoid paint buildup on edge details.

Q6: What plain moulding width is the 15×15cm corner decoration compatible with?
The 15×15cm corner decoration is compatible with plain mouldings having a face width not exceeding 15cm, and is especially suitable for narrow mouldings up to 8cm (such as 2cm, 5cm, and 8cm). Verify that the plain moulding face width matches the corner decoration specifications before purchasing.

Precautions

• Verify substrate flatness and a 90° corner angle 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 cause deformation or edge damage
• Cutting: Corner decorations typically require no cutting; Install as complete units. For custom sizing, score multiple times with a utility knife or use fine-tooth saw blades; 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. Due to the small size, control adhesive amount to avoid overflow
• 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 consistency across multiple batches before installation
• Avoid cleaning with strong acids, strong alkalis, or organic solvents
• Handle carefully during transport; Edges of the corner decoration are easily damaged. Avoid impacts
• If repainting, apply paint before installation; Touch up joints after installation
