FAQ's

Is marine plywood completely waterproof?

 Yes – marine plywood uses waterproof phenolic adhesives and water-resistant outer veneers. Unlike standard plywood, it's engineered for constant moisture exposure and won't delaminate when wet. Perfect for permanent water contact applications.

How strong is marine plywood?

 Extremely strong. The high-density multi-layer construction creates exceptional structural stability. The hardwood core and cross-bonded grain pattern deliver superior load-bearing capacity compared to standard exterior plywood.

Can I use marine plywood outdoors?

Absolutely. Marine plywood is specifically designed for outdoor and wet environments. It outperforms regular exterior plywood in moisture resistance, making it ideal for decks, docks, sheds, and any outdoor project exposed to rain or humidity.

What's the difference between marine plywood and exterior plywood?

Marine plywood uses higher-grade hardwood veneers and phenolic waterproof glue throughout. It must meet strict BS 1088 standards for moisture resistance and structural integrity. Standard exterior plywood uses different adhesives and lower-grade cores.
