Frequently Asked Questions

Polyurethane (PU) is a synthetic polymer material widely used in architectural decorations. PU decorative products are molded from high-density closed-cell foam, offering the visual appearance of traditional materials like wood or plaster while providing superior performance characteristics including water resistance, light weight, and durability.

When properly installed and maintained, PU decorative products can last 20-30 years or more. Unlike wood, PU does not rot, warp, or crack with humidity changes. Unlike plaster, PU is impact resistant and will not crack during transport or installation.

Yes. PU is completely waterproof and can be used in wet areas including bathrooms, kitchens, and even outdoor covered applications. Unlike wood or MDF, PU will not swell, warp, or deteriorate when exposed to water.

Standard PU products are designed for indoor use. For covered exterior applications (under eaves, porches), our exterior-grade products with UV inhibitors are recommended. Full sun exposure may cause surface degradation over extended periods.

Our standard PU products meet Class E (EN 13501-1) fire classification. Fire-retardant versions meeting Class B are available for commercial projects with stricter fire code requirements. Please specify fire-retardant requirements when requesting quotes.

Our PU products are manufactured without formaldehyde or other harmful chemicals. They emit zero VOCs and meet indoor air quality standards for residential and commercial interiors. Safety data sheets are available upon request.

PU products can be installed with standard woodworking tools: miter saw with fine-tooth blade, finish nails, construction adhesive, sandpaper, and standard painting supplies. No specialized equipment is required. The light weight of PU makes single-person installation possible for most applications.

DIY installation is feasible for homeowners with basic carpentry skills. However, for complex projects, large-scale commercial installations, or applications requiring precise fitting, professional installation is recommended. Our products are designed for straightforward installation.

Polyurethane construction adhesives such as PL Premium or equivalent provide the best bond. Apply adhesive in a zigzag pattern to the back of the product and press firmly against the mounting surface. For ceiling applications, supplement adhesive with finish nails until adhesive cures.

Use a miter saw with a fine-tooth blade (40+ teeth for 10-inch blade). Support long pieces to prevent vibration. For inside corners, coped cuts typically provide better appearance than mitered cuts. carbide-tipped blades last longer when cutting production volumes.

Yes. Construction adhesive provides excellent bonding to properly prepared surfaces. Ensure surfaces are clean, dry, and free from loose material. For very smooth surfaces (painted drywall), light sanding improves adhesion. Do not apply adhesive inside LED channels.

Outside corners typically use mitered joints. Inside corners are best handled with coped joints, where the profile of one piece is cut to match the profile of the other. Use paintable caulk or wood filler for small gaps. For large gaps, backer rod and caulk provide flexible repair.

Most of our products are factory-primed with a high-quality primer specifically formulated for PU surfaces. This factory priming eliminates on-site priming and significantly reduces finishing time. Simply apply topcoat paint directly to the primed surface.

Standard interior latex paints work well on primed PU products. For high-traffic or high-humidity areas, premium acrylic latex or bathroom/kitchen formulas provide better durability. Avoid solvent-based paints unless specifically formulated for plastics.

Due to the smooth, consistent surface of primed PU products, most installations require only one coat of topcoat paint. Dark colors or high-sheen finishes may require two coats for complete coverage. Always allow paint to dry fully between coats.

Our stainable-density products can accept gel stain for wood-appearance finishes. Apply gel stain per manufacturer instructions, then seal with clear topcoat. Results vary; testing on a sample piece is recommended before full application.

Minor dents or holes can be filled with lightweight spackle or vinyl spackling. Sand smooth when dry, apply primer, then topcoat. The paintable surface allows seamless touch-up repairs. Keep some leftover paint for future touch-ups.

MOQ varies by product type: standard profiles typically 100-200 linear meters; custom profiles require 500+ meters due to tooling costs; decorative pieces often available from 10 pieces. We offer sample orders for quality verification before bulk orders.

Standard products ship within 15-20 days from order confirmation. Custom profiles requiring new tooling take 25-35 days. Large orders may require additional production time. Rush orders are sometimes available with premium pricing.

Standard payment terms are 30% deposit, 70% balance before shipment. For established customers, credit terms may be available. We accept wire transfer, PayPal (small orders), and Letter of Credit for large orders.

We handle full container (20ft or 40ft) and less-than-container-load (LCL) shipments. Door-to-door delivery is available through our logistics partners. We also support consolidation services for mixed-product shipments.

Yes. Sample orders are available for most products. Sample fees are typically credited toward bulk orders. Shipping costs for samples are paid by the buyer. Contact us with your product requirements to request samples.

We primarily ship to commercial ports or freight-forwarder facilities. For small sample orders, residential delivery may be available through express courier services (DHL, FedEx, UPS). Contact us for shipping options and quotes.

Yes. We can reverse-engineer existing profiles from samples or detailed drawings. For complex profiles, CAD files or physical templates help ensure accuracy. New tooling may be required for accurate replication.

We can produce products in virtually any size. Standard tolerances are ±2mm. Tighter tolerances are available for premium pricing. Custom sizes typically require new tooling and have higher MOQs.

Factory finish options include white primer, custom color matching (minimum order quantities apply), and wood-grain finishes. Most customers prefer to paint our primed products on-site for color matching to adjacent trim.

Yes. We provide comprehensive OEM/ODM services including custom formulations (density, fire rating, flexibility), proprietary tooling, branded packaging, and documentation. We work with distributors, retailers, and project specifiers worldwide.

Standard packaging is kraft paper wrapping with corner protection. Premium packaging options include individual foam wrapping, branded boxes, and display-ready packaging. Custom packaging requires minimum quantities and setup fees.

Our standard products range from 240-320 kg/m³ depending on profile complexity and performance requirements. Higher density products offer better impact resistance and paint hold; lower densities are more cost-effective for non-structural applications.

Our standard products maintain structural integrity from -30°C to +80°C. This range covers virtually all interior applications and most covered exterior uses. Thermal expansion is minimal due to the closed-cell structure.

PU products are ideal for humid environments. The closed-cell structure absorbs virtually no moisture, preventing the swelling, warping, and mold growth common with wood-based materials. This makes PU ideal for bathrooms, pools, and coastal applications.

Our high-density PU products hold screws comparable to softwood lumber. Standard wood screws provide adequate holding for most applications. For heavy loads, use expansion anchors or through-bolts. Pre-drilling is recommended for cleaner fastener placement.

Yes. PU products are designed to integrate seamlessly with standard trim carpentry. Standard finish nails, construction adhesive, and finishing techniques all work well. No specialized tools or training are required.
