A wall applique or onlay is a small decorative element applied to a wall or a door, designed to add a classical detail to the surface. The applique is typically a small PU casting with a developed pattern (a rosette, an acanthus leaf, a scroll, a floral motif), glued to the surface with construction adhesive.
The most common applique application is a door upgrade. A plain flush door is upgraded with a few appliques applied to the upper portion of the door. The appliques add a classical detail to the door and transform it from a utility element to a designed element.
A second common application is a wall focal point. A single applique or a small composition of appliques applied to a wall as a focal point. The applique is centered on the wall, with the design visible from the room.
A third common application is a furniture upgrade. A plain cabinet, sideboard, or headboard is upgraded with appliques applied to the surface. The appliques add a classical detail to the furniture and transform it from utility to designed.
A fourth common application is a frame or mirror upgrade. A plain frame or mirror is upgraded with appliques applied to the corners or the center of the frame. The appliques add a classical detail to the frame.
A fifth common application is a ceiling ornament. A small applique applied to the ceiling as a decorative element, often in a corner or at the center of a ceiling panel.
For sourcing, PU appliques and onlays are a stock product at most factories. The factory offers a range of standard designs (rosettes, acanthus, scrolls, florals) in a range of standard sizes, with quick lead times and competitive pricing. Custom designs are available on longer lead times.
A practical install note: an applique is glued to the surface with construction adhesive, with a few brad nails to hold it in place while the adhesive sets. The applique should be positioned carefully (often with a pencil outline on the surface), and the adhesive should be applied to the back of the applique in a continuous bead. The brad nails are set below the surface and filled with wood filler or paintable caulk.
A practical note on the surface. The applique can be applied to almost any smooth surface — drywall, wood, MDF, plywood, metal, or previously painted surfaces. The surface should be clean and sound, with any loose paint or wallpaper removed before the applique is applied. The adhesive bonds well to most surfaces, and the brad nails provide additional holding power.

Frequently Asked Questions
Q: What is polyurethane (PU) decorative material?
A: Polyurethane (PU) decorative material is a high-density closed-cell polymer molded into architectural profiles such as cornices, ceiling medallions, wall panels, columns, and skirting boards. It replicates the appearance of plaster, carved wood, or stone at one-quarter the weight, is fully waterproof, impact-resistant, and arrives factory-primed for paint.
Q: How does PU compare with plaster and wood mouldings?
A: PU is lighter than plaster (no scaffolding required), impact-resistant during transport, and immune to cracking. Compared with wood, PU does not warp, split, or attract termites, and it tolerates moisture in bathrooms and kitchens. The trade-off: PU cannot be refinished the way solid wood can, but its lifespan is 20–30+ years with minimal maintenance.
Q: How do you cut and finish PU mouldings?
A: Cut PU mouldings with a fine-tooth miter saw (40+ teeth for a 10-inch blade) to avoid chipping the molded edge. Sand the cut edge with 220-grit, then apply two coats of interior latex paint. Mitre joints at corners, fill seams with lightweight spackle, sand smooth, and finish with one final top coat.
Q: Is PU moulding safe for indoor air quality?
A: Yes. Premium PU mouldings are manufactured without formaldehyde, asbestos, or VOCs. They meet EN 13501-1 Class E fire classification as a minimum, with Class B fire-retardant versions available for commercial projects. The factory-applied water-based primer further reduces off-gassing once installed.
