Introduction to Moisture Resistant Plywood
In woodworking, moisture is often the main cause of damage. Too much exposure to humidity can lead to swelling, warping, and even breakage of wooden furniture. This is where moisture resistant plywood becomes important. It is designed to handle some level of dampness and has become a popular choice for both home and office interiors.
Why Moisture Resistance Matters in Woodwork
Picture buying a brand new wardrobe that starts to swell during the rainy season. That can be frustrating. Moisture resistance helps keep woodwork strong and long-lasting even in humid conditions, making it a great option for use over time.
What is Moisture Resistant Plywood?
Moisture resistant plywood, commonly known as MR plywood, is a type of wood that can resist moisture and humidity to a large degree. It is made by bonding high-quality hardwood veneers with urea-formaldehyde resin under heat and pressure. Although it is not completely waterproof, it can handle occasional exposure to moisture and dampness without major issues.
How is it manufactured?
The manufacturing process involves:
- Selecting hardwood veneers.
- Treating them with resins.
- Pressing them under high temperature and pressure.
- Finishing with sanding for smoothness.
This process ensures the plywood can resist swelling and damage when exposed to moisture.
Difference Between MR and Waterproof Plywood
- MR Plywood: Resists moisture but is not completely waterproof. It is best suited for interior use.
- BWR/BWP Plywood: Boiling Water Resistant or Boiling Water Proof. These can withstand continuous water exposure, making them suitable for use outdoors.
Key Features of Moisture Resistant Plywood
- Durability and Strength – Can last for years with proper care.
- Resistance to Humidity – Ideal for areas with frequent rain.
- Smooth Surface – Perfect for polishing and laminating.
- Cost-Effective – More affordable than marine or BWR plywood.
Applications of Moisture Resistant Plywood
- Furniture Making – Beds, tables, chairs.
- Kitchen Cabinets & Wardrobes – Can handle steam and humidity.
- Office Interiors – Workstations and partitions.
- Wall Panelling & Ceilings – Adds a stylish look while staying durable.
- Doors & Partitions – Prevents warping and cracking.
Benefits of Using Moisture Resistant Plywood
- Covers a wide range of uses.
- Long-term value for money.
- Environment-friendly production methods.
- Better value compared to MDF or particle board.
Comparison with Other Materials
- MR vs BWR – BWR is waterproof, MR is moisture resistant.
- MR vs Marine – Marine plywood is for boats and extreme wet conditions.
- MR vs MDF – MDF is cheaper but not as strong against moisture.
Choosing the Right Moisture Resistant Plywood
- Thickness Options – Available in 6mm to 19mm.
