58cm*3m Wood-Grain Acoustic Grille Sticker

Key Advantages

• Self-adhesive installation: Pre-applied pressure-sensitive adhesive layer; Peel and stick without drilling, gluing, or professional tools.
• Acoustic absorption: The three-dimensional grille structure increases surface area for sound wave reflection. Rated Noise Reduction Coefficient (NRC) ≥0.3 For medium to high frequencies.
• Wood-grain simulation: Printed wood-grain pattern with annual ring and导管 details that match reference samples.
• Flexible adhesion: Material bends to fit slightly curved or non-flat walls; Passes 100mm diameter bend test without cracking.
• Water and moisture resistance: Continuous waterproof surface layer suitable for indoor dry or moderate humidity environments such as living rooms and hallways.

Product Characteristics

Application Scenarios

• Living room walls: TV background walls, sofa back walls, full decorative walls.
• Bedrooms: Headboard walls, wardrobe side panel decoration.
• Entryways and hallways: Entrance walls, corridor walls.
• Commercial spaces: Cafes, restaurants, offices, exhibition hall walls.
• Acoustic spaces: Home theaters, recording rooms, conference rooms for supplementary acoustic treatment.

Common Precautions

• Substrate requirements: Substrate must be flat, dry, free of oil, grease, loose dust, and peeling paint. For latex paint walls, verify that the paint film is firmly bonded; Loose sections must be scraped and sanded.
• Substrate flatness: Walls with height variations exceeding 1.5mm per meter require leveling to ensure full contact between grille strips and the wall surface for secure adhesion.
• Pre-installation cleaning: Clean substrate with mild detergent to remove oil and wax. For tile walls, light sanding is recommended to increase roughness and improve adhesion.
• Application procedure: Peel off the release film, align from one edge, and press down. Use a squeegee or roller to apply even pressure, ensuring full contact between grille strip bases and the wall surface. Align patterns at seams.
• Ambient temperature: Recommended installation temperature is no lower than 10°C. At low temperatures, initial tack is reduced; Use a hair dryer to warm the adhesive layer evenly before application.
• Cutting method: Cut with a utility knife along the gaps between grille strips using a sharp blade to avoid burrs. Use 45° miter cuts for corner joints.
• Cleaning and maintenance: Use a vacuum cleaner with a brush attachment to remove dust from grille gaps, or wipe gently with a slightly damp soft cloth following the grille direction. Avoid direct high-pressure water spraying.
• Storage conditions: Store rolls flat in a cool, dry place away from direct sunlight and high temperatures. Storage temperature should not exceed 35°C with humidity below 70%.
• Removal method: Heat the surface to 50-60°C with a heat gun to soften the adhesive, then peel from corners. Residual adhesive can be removed with adhesive remover or rubbing alcohol.
