PU Brick Veneer Panels

Product Definition

   PU Brick Veneer Panels are prefabricated wall decorative materials with rigid polyurethane as the base material, whose surface is formed by molds and coated with a weather-resistant coating. It transfers the texture, brick joints and surface texture of traditional brick walls or stone walls to the panels through molds in one go, realizing the industrial production of "masonry effect".

   Different from real brick masonry, this product does not rely on mortar bonding and manual pointing, but is directly fixed on the base wall by gluing or dry hanging. It mainly solves three practical problems: wall load limitation, long construction period and uncontrollable material color difference.

2. Materials and Structure

Layer Composition

   There are five layers from outside to inside:

• Transparent Protection Layer: High-hardness polyurethane varnish with pencil hardness 2H. It mainly prevents scratches during transportation and installation.
• Weather-Resistant Color Paint Layer: Aliphatic polyurethane with ceramic pigments added. After 2000 hours of QUV aging test, the color difference ΔE ≤ 2, with no obvious chalking.
• Texture Layer: Reproduced from the surface of real bricks by silicone molds, including details such as fired pores, edge wear and fine cracks. The touch is rough, not a smooth surface.
• Primer Sealing Layer: Used to improve the adhesion between the texture layer and the foam core, and at the same time seal the pores on the foam surface to prevent moisture from seeping through the cut.
• Polyurethane Core: Density 400–500 kg/m³, closed-cell structure, compressive strength ≥1.2 MPa. It bears the mechanical properties and lightweight characteristics of the panel.

Molding Method

   Adopting negative pressure casting process. Liquid polyurethane is injected into the preheated silicone mold, demolded after foaming and curing, then trimmed, sprayed with topcoat, and back-coated with anti-adhesive layer (optional). The mold is reproduced from standard clay bricks, with high texture precision and good batch consistency.

5. Installation Methods

• Adhesive Bonding MethodApplicable to solid substrates such as concrete, cement mortar and old tiles. Use polyurethane structural adhesive, and the gluing area on the back of the panel shall not be less than 60% (exterior wall) or 40% (interior wall). After pasting, tap lightly with a rubber hammer to ensure full contact of the adhesive.
• Dry Hanging MethodApplicable to steel structures, wooden frames or scenarios requiring ventilated exterior walls. Fix the panels on the base course through stainless steel hangers or aluminum alloy keels, and the back of the panels is prefabricated with installation notches. The dry hanging method can form an air layer, which is conducive to drainage and thermal insulation.
• Mixed FixationUsed for high-rise buildings or high wind pressure areas. On the basis of gluing, add stainless steel screws for auxiliary fixation. The screw spacing shall not be greater than 500 mm. After the screw head sinks into the reserved pit of the panel, cover it with color-matched repair paste.
• CuttingUse a cemented carbide circular saw blade or jigsaw. It is recommended to feed the knife from the back of the panel to avoid chipping of the front coating.

7. Frequently Asked Questions

1.Is there a big difference in appearance between PU brick veneer panels and real brick walls?

   The front texture and color are close to real fired bricks. The differences are mainly reflected in the knocking sound and back material. The front touch is rough due to the addition of aggregates, which is similar to real brick walls.

2.Can it be used for exterior walls of high-rise buildings?

   Yes. The B1 fire rating meets the specifications of most high-rise buildings. For buildings above 100 meters, dry hanging or mixed fixation is recommended, and special wind pressure calculation shall be carried out. The self-weight of the panel is low, and the requirement for keel load is much lower than that of real bricks and stones.

3.How to clean the surface?

   The surface is hydrophobic, and most dust can be removed by rain washing. For long-term dust accumulation, a low-pressure water gun (≤8 MPa) or a soft brush with neutral detergent can be used. Avoid using strong acid, strong alkali or high-pressure water gun for close-range flushing.

4.How to handle panel joints?

   The edge of the panel is designed as a stepped lap joint or tongue-and-groove structure. After installation, a shadow gap consistent with the width of the prefabricated brick joint is naturally formed. If waterproof sealing is required, color-matched polyurethane sealant can be filled.

5.Can it be installed on curved walls?

   The panel has a certain flexibility, with a minimum bending radius of about 3 meters (along the length direction). For smaller radians, custom curved molds are required.

6.How to obtain samples?

   200×200 mm actual panel samples are provided free of charge (freight collect). A small mold fee is required for custom color samples.

7.What is the warranty period?

   Standard warranty is 10 years, covering manufacturing defects such as coating fading (ΔE > 5), delamination and cracking. For extreme climate areas, enhanced coating can be selected, and the warranty is extended to 15 years.

8.How does the comprehensive cost compare with real brick walls?

   Taking 100 m² exterior wall as an example, the cost of real brick masonry (masonry + plastering + pointing) is about 28,000–35,000 yuan; the cost of PU brick veneer panels (panels + glue + labor) is about 22,000–28,000 yuan. The comprehensive cost is 20–30% lower, and the construction period is shortened by about 70%.
