Key Advantages

• Face width of 8.5cm, suitable for common corner trim and corner protection applications
• Plain smooth design without patterns; Compatible with various interior styles and existing finishes
• Low-density PU material reduces weight, allowing single-person handling and installation
• Water and moisture resistance: Non-absorbent and non-expanding; Suitable for kitchens, bathrooms, and other humid areas
• Aging resistance: No embrittlement or powdering; Physical properties remain stable over long-term use
• Workability: Cuttable with a utility knife; No power tools required

Product Features

Application Scenarios

• Interior corner trim (ceiling-wall junctions)
• Wall corner protection (external wall corner protection and finishing)
• Ceiling edge finishing (transition between ceiling edge and wall)
• Beam and column edge covering (edge finishing for structural beams and columns)
• Baseboard top trim (decorative trim above baseboards)
• Wainscoting edge finishing (top and bottom edge trim for wall panels)
• Minimalist style interiors (plain straight-line trim for clean finishes)
• Commercial spaces (office buildings, shopping malls, hostels, hotels)

Frequently Asked Questions

Q1: What is the difference between plain corner moulding and carved moulding?
Plain corner moulding has a smooth, pattern-free surface designed for minimalist trim applications where decorative patterns are not required. Carved mouldings feature three-dimensional patterns suitable for accent wall borders, waistlines, and decorative applications. The two types can be used together depending on interior style requirements.

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. Apply adhesive to the back of the moulding, press into place. For corners, use 45° miter cuts. Use painter's tape for temporary fixing until the adhesive is fully cured.

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

Q4: How is the product cut?
Score the cutting line 3-5 times with a sharp utility knife to a depth of at least half the moulding thickness, then snap backward. Alternatively, use a fine-tooth saw (tooth spacing ≤ 3mm) or miter saw for cleaner cuts. Apply color-matched paint or filler to cut edges.

Q5: Can the product be used on exterior walls or outdoors?
This product is designed for interior use. Short-term use in semi-outdoor areas (such as covered balconies or porches) is acceptable. For long-term fully exposed outdoor applications, select outdoor-grade PU moulding products with enhanced UV resistance formulas.

Q6: How are corners handled?
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. For butt joints where miter cuts are not required, cut one end at 90° and overlap it over the other end, then fill the joint with filler.

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
• Use a sharp utility knife when cutting; Wear protective gloves. Lightly sand uneven cut edges with fine sandpaper
• Recommended installation ambient temperature: 5°C to 35°C. Avoid low temperatures that may slow adhesive curing
• Apply adhesive evenly and ensure full contact between moulding and substrate; Secure with painter's tape
• Joint treatment: Apply filler to butt joints, smooth with a damp cloth, and lightly sand with fine sandpaper after drying
• Inspect color consistency across multiple batches before large-scale installation
• Avoid cleaning with strong acids, strong alkalis, or organic solvents
• For white wall applications, plain corner mouldings are typically white or paintable. For color changes, use water-based or polyurethane paints
• Handle carefully during transport to prevent edge and corner damage
