Comment poncer du contreplaqué

Step-by-Step Process:

1. Choose a thin, flexible plywood sheet (preferably 1/8″ or 3.2 mm thick)
2. Prepare your bending form with a smooth, curved surface
3. Soak the plywood thoroughly in hot water or apply steam
4. Gradually bend the plywood around your form
5. Secure with clamps and allow to dry completely

How to Bend Plywood for Furniture

When creating furniture, follow these additional tips:

• Use multiple thin layers laminated together for complex curves
• Apply waterproof glue between layers for strength
• Allow extended drying time (24-48 hours)
• Use a backup form to maintain shape while drying

How to Bend Plywood into a Circle

For perfect circular bends:

• Create a precise circular form
• Mark your desired radius
• Use multiple smaller segments for larger circles
• Apply even pressure during bending
• Typical minimum radius: 12″ (305 mm)

How to Bend Plywood with Hot Water

Hot water method is most effective:

• Water temperature: 160-180°F (71-82°C)
• Soak time: 15-30 minutes depending on thickness
• Use protective equipment
• Bend slowly and consistently
