HIGH-PRESSURE PREFINISHED WOOD VENEER

“DuraVeneer” is manufactured with natural, not reconstituted wood veneer that has a protective melamine resin wear layer and fused with phenolic resin-impregnated kraft sheets. The result is a pre-finished, ready-to-fabricate veneer that features a maintenance-free, scratch-resistant surface.

Due to the inherent properties of real wood and the varying number of sheets that are cut from any given log, variations in color and grain will appear from one DuraVeneer sheet to another. This is a normal occurrence, and not a defect. A natural maturing and mellowing of color may also occur with age.

 

MATERIALS

A. “DuraVeneer” High-Performance Wood Veneer.

1. Use: Interior applications.

2. Conformance: EN 438-2.

3. Manufacturing Process:

• Impregnate genuine wood veneers with a protective melamine resin and fuse with phenolic resin-impregnated Kraft sheets.
• Perform lamination under a minimum pressure of 500 psi (3,447 kPa) and at a temperature of approximately 121 degrees C.
• Sand pressed laminate to provide uniform thickness and to facilitate adhesive bonding.
• Contains no added urea-formaldehyde.

 

Note: “DuraVeneer” High-Performance Wood Veneer is classified Class II in accordance with ASTM E 84. Fire-Rated Class I high-pressure decorative wood veneer laminate is available as a special order item and is recommended for interior applications where the decorative surface must resist combustion and inhibit smoke production. Consult Lamin-Art, Inc. for more information, including availability and lead time, regarding Fire-Rated Class I high-pressure decorative wood veneer laminate.

 

Applicable Usage:

A. ANSI A208.1 – Particleboard e.g. for furniture

B. ANSI A208.2 – Medium Density Fiberboard (MDF) for e.g. interior wall decoration

C. ANSI/NEMA LD 3 – High Density Fiberboard (HDF) e.g. wood flooring

D. Plywood 

E. Rigid Plastic Boards

 

Adhesives:

Use for bonding high-pressure decorative wood veneer laminate to substrates.

1. Contact adhesive.

2. Polyvinyl acetate resin (PVA) adhesive.

3. Urea adhesive.

4. Resorcinol resin adhesive.

5. Hot-melt adhesive.

6. Epoxy adhesive.

 

Backing Sheets:

1. Kraft-paper core sheets impregnated with phenolic resin.

2. As necessary to balance assembly and prevent warping.

 

SHOP FABRICATION

A. Inspection:

1. Inspect high-pressure decorative wood veneer laminate surfaces before lamination to ensure they are sound, dry, clean, and free of surface defects.

2. Remove protective peel coat, if applicable, before inspection.

3. Correct defects before lamination.

 

B. Preparation:

1. Sand and prepare substrates and high-pressure decorative wood veneer laminate as required to provide a smooth and clean surface that is free of dirt, dust, moisture, oil, grease, or other impurities that would interfere with adhesion.

2. Ensure substrates are uniform in thickness and free of defects.

 

C. Fabrication:

1. Ensure materials, equipment, and workmanship are in accordance with:

a. ANSI/NEMA LD 3.

b. AWI Architectural Woodwork Standards.

 

2. Bond high-pressure decorative wood veneer laminate to substrates using adhesives in accordance with adhesive manufacturer’s instructions.

a. Do not use pressure greater than 45 psi to avoid starved glue line or telegraphing of substrates.

 

3. Minimize excessive moisture imbalance between high-pressure decorative wood veneer laminate and substrates by preconditioning materials for 8 to 10 days before fabrication at 18 degrees C to 22 degrees C and 50 percent to 60 percent relative humidity.

 

4. Provide air circulation around high-pressure decorative wood veneer laminate and substrates during preconditioning.

 

5. Machine factory edges before seaming and clean thoroughly with denatured alcohol.

 

6. Sealing Edges and Seams: Seal exposed edges and seams of high-pressure decorative wood veneer laminate with diluted urethane or clear varnish to prevent moisture penetration/absorption and expansion and contraction which could damage veneer.

 

 

D. Cleaning:

1. Clean high-pressure decorative wood veneer laminate promptly after fabrication in accordance with manufacturer’s instructions.

2. Do not use harsh cleaning materials or methods that could damage laminate.

E. Protection: Protect fabricated high-pressure decorative wood veneer laminate from damage.

 

DELIVERY, STORAGE, AND HANDLING

A. Delivery Requirements: Deliver materials to site in manufacturer’s original, unopened containers and packaging, with labels clearly identifying product name and manufacturer.

B. Storage and Handling Requirements:

1. Store and handle materials in accordance with manufacturer’s instructions.

2. Keep materials in manufacturer’s original, unopened containers and packaging until fabrication and installation.

3. Store materials in clean, dry area indoors.

4. Store materials out of direct sunlight.

5. Keep materials from freezing.

6. Store high-pressure decorative wood veneer laminate horizontally, back-to-back, face-to-face, with top sheet turned face-down and caul board placed on top to protect laminate from damage and to reduce chance of warping of top sheets.

7. Store high-pressure decorative wood veneer laminate and substrates for 8 to 10 days before fabrication at 18 degrees C to 22 degrees C and 50 percent to 60 percent relative humidity.

It is critical that all edges of Veneer MUST be sealed using a clear varnish or other suitable sealer to prevent moisture penetration/absorption.

8. Protect high-pressure decorative wood veneer laminate from light, heat, and moisture.

9. Protect high-pressure decorative wood veneer laminate from contact with floors and exterior walls.

10. Protect corners of high-pressure decorative wood veneer laminate from damage.

11. Protect materials during storage, handling, fabrication, and installation to prevent damage.
