The surface finishes for PU Stone Panel – Which One Is Right for You?

Selecting a PU stone panel finish isn't just about color and style. The wall panel's surface finish affects texture, durability, and total cost.

This guide compares two core processes and three color tiers of the polyurethane artificial stone panel, so you can match the right panel to your project's requirements, such as condition, climate, lifespan, and budget.

Two Surface Finish Technologies

1. PVC Film Lamination (Budget-Friendly)

Process: The surface is laminated with a PVC film and then spray-painted. This process is stable, highly efficient, and offers excellent cost-effectiveness.

Although the texture definition is slightly inferior to that of in-mold painting, the visual appearance remains impressive.

Best for: Interior walls, covered patios, and exteriors under eaves.

Lifespan: 8-15 years outdoors. (Depends on condition)

Texture: Smooth and consistent, suitable for modern minimalism.

Choose this if: You have a regular budget and a shorter-term project.

2. In-Mold Painting (Premium Durability)

Process: The color coating and substrate are molded together in a single step, ensuring the surface coating fuses perfectly with the base material to create a fine, natural texture.

A protective topcoat is subsequently applied to ensure superior weather resistance.

Best for: Full facades, harsh sun, extreme temperatures, or seaside locations.

Lifespan: 20+ years outdoors.

Texture: Fine, natural stone grain with micro-porosity.

Choose this if: Your building is a permanent investment and replacement costs are higher than the PVC lamination.

Coloring process – Three Tiers to Suit Every Design

1. Solid Colors – Uniform tones (black, white, cement grey). Perfect for large-volume projects where consistency matters.

2. Gradient Colors – Multi-tonal layering creates natural color shifts and depth, mimicking real stone.

3. Hand-Painted Custom – Artisans hand-blend pigments for unique textures and artistic variations. Ideal for luxury interiors or landmark projects where no two panels are alike.

How to Choose the Right Finish

Both Film Lamination and In-Mold Painting can be used for interior and exterior applications. The main difference is their expected outdoor service life and cost.

These are general recommendations. The final finishing and coloring process can be selected according to the project requirements, expected service life, design preferences, and budget.

Quick FAQ

Q: Can Film-laminated panels go outdoors?
A: Yes, but only in shaded areas. For full sun or rain, upgrade to In-Mold.

Q: Are hand-painted panels worth the extra cost?
A: For premium, custom aesthetics – absolutely. They offer unlimited color matching that standard gradients can't.

Q: How to clean both finishes?
A: A soft cloth with clean water. Avoid abrasive tools on Film surfaces.
