Introduction
Plywood is one of the most popular materials for outdoor furniture, thanks to its versatility, durability, and cost-effectiveness. In Bengaluru, where the weather ranges from moderate to highly humid, choosing the right type of plywood for outdoor use is crucial. This guide covers the essentials of selecting plywood for outdoor furniture in Bengaluru, including the types, treatments, design ideas, and maintenance tips.
Why Choose Plywood for Outdoor Furniture?
1. Versatile and Cost-Effective
- Plywood is a versatile material that can be cut, shaped, and customized to fit various design styles. It's also more affordable than solid wood, offering a cost-effective option for outdoor furniture projects.
2. Durable and Strong
- With proper treatment, plywood is resilient enough to handle Bangalore's varying climate, which includes hot summers and monsoon seasons. Outdoor-grade plywood is made to withstand these conditions, providing strength without warping or swelling.
3. Sustainable Choice
- Plywood is made by layering thin sheets of wood veneer, maximizing the yield from each log and making it a more sustainable choice compared to solid wood options.
Types of Plywood for Outdoor Furniture
When choosing plywood for outdoor furniture in Bengaluru, ensure it's designed to withstand the elements. Here are the recommended types:
1. Marine Grade Plywood
- Characteristics: Marine-grade plywood is made from durable hardwood veneers and is treated with waterproof glue. It’s built to withstand exposure to moisture without delaminating.
- Advantages: Its resistance to water and humidity makes it an excellent choice for Bengaluru’s monsoon-prone climate.
- Best Use: Ideal for garden benches, patio furniture, and other outdoor pieces exposed to rain or moisture.
2. BWP (Boiling Water Proof) Plywood
- Characteristics: BWP plywood, often marketed as "waterproof plywood," is designed to resist water and prevent fungal growth, making it a popular choice for humid climates.
- Advantages: This plywood type is durable, pest-resistant, and doesn't warp in high humidity.
- Best Use: Suitable for outdoor dining tables, chairs, and accent pieces that require water resistance and durability.
3. Exterior Grade Plywood
- Characteristics: Exterior-grade plywood is treated with a weather-resistant adhesive and is manufactured for outdoor use. While not as water-resistant as marine-grade plywood, it’s designed to withstand moderate moisture and temperature fluctuations.
- Advantages: This option is budget-friendly and can be used in partially sheltered outdoor areas.
- Best Use: Perfect for sheltered patios or covered outdoor areas where the furniture isn’t directly exposed to rain.
4. Hardwood Plywood with Weatherproof Coating
- Characteristics: Made from strong hardwoods, this plywood type can be coated with a weatherproof sealant to make it suitable for outdoor use.
- Advantages: With proper treatment, it offers high durability and strength, making it resistant to pests and moisture.
- Best Use: Ideal for benches, chairs, and small tables in covered outdoor spaces.
Tips for Choosing the Right Plywood for Outdoor Furniture
1. Look for ISI or BIS Certification
- Ensure that the plywood you choose is certified by ISI (Indian Standards Institute) or BIS (Bureau of Indian Standards), which indicates it meets quality standards for strength, durability, and weather resistance.
2. Consider Thickness
- For outdoor furniture, a plywood thickness of 18-25mm is recommended, as it provides additional strength and durability, especially for larger pieces like benches or tables.
3. Check for Waterproof Glue
- Plywood made with waterproof glue is ideal for outdoor use. Waterproof glue, also known as phenolic glue, provides strong bonding and helps the plywood resist moisture penetration.
4. Opt for Chemical Treatments
- Some plywood products are chemically treated to resist pests and mold growth, which can be especially beneficial in Bangalore's humid climate.
Design Ideas for Outdoor Plywood Furniture
1. Rustic Garden Benches
- Use marine-grade plywood to build sturdy garden benches with a rustic or natural wood finish. Adding a waterproof coating will keep the bench looking fresh and help it withstand Bengaluru's rainy season.
2. Outdoor Dining Sets
- Create a chic outdoor dining set with BWP plywood. Paint or stain the plywood for a vibrant look, and add a UV-protectant layer to prevent fading from the sun.
3. Patio Daybeds or Loungers
- With exterior-grade plywood, you can build a cozy daybed or lounger. Add weather-resistant cushions, and place it in a shaded area to create a relaxing space.
4. Minimalist Coffee Tables
- Use hardwood plywood with a weatherproof finish to build sleek, minimalist coffee tables for patios or balconies. Opt for a natural wood stain or a matte finish for a contemporary look.
5. Storage Benches
- Build functional storage benches with exterior-grade plywood. These benches can double as seating while providing storage space for gardening tools, cushions, or outdoor games.
Treatment and Finishing Options for Plywood
1. Waterproof Sealants and Varnishes
- Applying a layer of waterproof sealant or varnish is essential to protect plywood from moisture. Look for sealants specifically designed for outdoor use, which will protect the wood from both water and UV rays.
2. Oil-Based Stains
- Oil-based stains not only enhance the natural wood grain but also penetrate deep into the plywood, providing long-lasting moisture protection.
3. Paint with UV Protection
- Use high-quality, outdoor-grade paint with UV protection to keep colors vibrant and prevent peeling over time. Painted plywood can be a stylish option for modern outdoor furniture.
4. Apply a Clear Epoxy Resin Coating
- For extra protection, a clear epoxy resin coating can seal the plywood, making it highly water-resistant. This option is ideal for plywood that will be exposed to direct rain or placed near water features.
Maintenance Tips for Outdoor Plywood Furniture
1. Regular Cleaning
- Dust and debris can cause minor abrasions on the plywood surface. Clean the furniture regularly with a damp cloth, and avoid using harsh chemicals that may damage the protective finish.
2. Reapply Sealants Annually
- To maintain durability, reapply a waterproof sealant or varnish every year. This keeps the plywood water-resistant and prevents damage from Bangalore’s monsoon rains.
3. Cover Furniture During Extreme Weather
- Use furniture covers during heavy rains or intense sun exposure. This will extend the life of the plywood and prevent potential warping or fading.
4. Avoid Direct Contact with Water
- While outdoor-grade plywood is water-resistant, it’s best to avoid prolonged exposure to standing water. Place furniture on slightly raised bases to prevent water from pooling around the legs.
5. Check for Signs of Mold or Mildew
- In humid climates, mold and mildew can develop over time. Regularly inspect your furniture for signs of these growths, and treat any affected areas with a mild solution of water and vinegar.
Where to Find Quality Outdoor-Grade Plywood in Bengaluru

Look for reputable suppliers who offer certified products and are knowledgeable about the right materials for outdoor applications.
