Waterproof Plywood Cost: What Affects the Price

When it comes to home improvement or construction projects, plywood is often a go-to material. It’s versatile, and durable, and comes in various types, one of the most popular being waterproof plywood. But what affects the cost of waterproof plywood? Let’s break it down in simple terms.

What Is Waterproof Plywood?

Before diving into what affects the price, it’s essential to understand what waterproof plywood is. As the name suggests, this type of plywood is designed to resist water damage. It’s made by bonding layers of wood veneers together with waterproof adhesive, so it can withstand moisture, humidity and even direct contact with water without warping or deteriorating. Regular plywood, by contrast, is prone to swelling, warping and breaking down when it gets wet.

Where Waterproof Plywood Is Used

Waterproof plywood belongs anywhere moisture is constant or water exposure is likely:

• Kitchen and bathroom cabinets: Stays durable in high-moisture rooms.
• Basements: Suits areas where moisture is constant.
• Flooring: Works as a subfloor or finished surface in moisture-prone areas.
• Wall panelling and ceilings: A moisture-resistant option for interiors.
• Outdoor furniture and decks: Marine-grade sheets withstand outdoor weather.
• Boat-building: Marine-grade plywood lasts in water-exposed environments.

Without this protection, wood in these places can warp, swell or rot over time, leading to costly repairs. Preventing that damage keeps maintenance and repair costs down over the life of the project. For cabinet-specific advice, see our guide on protecting kitchen cabinets from water.

Which Plywood Is Most Waterproof?

When it comes to waterproof plywood, Marine plywood is considered the most water-resistant option available. Specifically designed for use in areas exposed to water and moisture, such as boats and coastal structures, marine plywood is made with high-quality wood veneers that are bonded together using waterproof adhesives.

This ensures that the plywood can withstand constant exposure to water without warping, delaminating, or rotting. In addition to its superior waterproofing, marine plywood is also highly durable and offers excellent strength, making it the top choice for projects where moisture is a significant concern. Our marine plywood buying guide covers it in more detail.

Factors Affecting Waterproof Plywood Prices

• Thickness: The thickness of the plywood sheet is a significant factor. Thicker sheets (like 19mm) are usually more expensive than thinner ones (like 6mm) because they offer more strength and durability.
• Grade: Plywood comes in different grades, with A-grade being the highest quality, free from knots or imperfections, and C-grade being more affordable with visible flaws. Higher-grade plywood is naturally more expensive.
• Brand: The brand can also impact the price. Well-known brands might charge more for their reputation and quality assurance, but sometimes, lesser-known brands offer similar quality at a lower cost.
• Location: Prices can vary depending on where you’re buying from. Urban areas or regions with higher demand might have slightly higher prices compared to rural areas.
• Quantity: Buying in bulk usually gives you a better deal. If you need a large amount of plywood, it might be worth negotiating with suppliers for a discount.

Because prices change with all of these factors, ask a supplier for a current quote.

What to Check in a Good Waterproof Sheet

Whatever you pay, make sure the sheet has the features that make waterproof plywood worth buying:

• Water-resistant resins and adhesives: Good bonding stops the sheet from swelling or cracking in wet conditions.
• Flat, stable construction: The board should stay flat and stable as the weather changes, rather than warping.
• Termite and borer treatment: Sheets treated with anti-termite and anti-borer chemicals are protected against pest damage.
• The right thickness and size: Choose a thickness and sheet size that suit the job, from cabinets to flooring.
• A good finish: A smooth face takes veneers and other finishes well if the plywood will be on show.

At MRS Woodcraft, our waterproof plywood range, including marine-grade sheets, is made with water-resistant resins and adhesives, treated against termites and borers, and available in multiple thicknesses and sizes for residential and commercial projects.

Tips For Buying Waterproof Plywood

• Compare Prices: Don’t settle for the first price you see. Check different suppliers, both online and offline, to get the best deal.
• Check Quality: Even if you’re on a budget, don’t compromise on quality. Ask for samples or visit the store to check the plywood before buying.
• Consider Future Needs: If you think you’ll need more plywood for future projects, it might be more cost-effective to buy in bulk now.
• Ask for Guarantees: Some brands offer guarantees or warranties on their waterproof plywood. This can be a good indicator of quality and offer peace of mind for your purchase.

Conclusion

Waterproof plywood is an excellent investment for projects where moisture resistance is crucial. While the prices might vary, understanding the factors that affect the cost can help you make an informed decision. Remember, it’s not just about finding the cheapest option, but getting the best value for your money.
