Unlike many people think, marine plywood is not waterproof. However, it is still a good type of plywood, made up of hardwoods and waterproof glue. As a result, marine plywood is trusted to use in many outdoor exterior projects in coastal areas where there is high warmth or a smart choice for building materials and boat parts.
The characteristics of marine plywood are hardness, durability, lightweight, and much better price than traditional sawn timber. Can resist moisture long term and against the attack of fungi.
According to The Engineered Wood Association (EWA), marine plywood divided into categories:
-Average coverage density (MDO)
-High density (HDO)
3. Glue waterproof
Marine plywood uses WBP waterproof glue (Water Boiled Proof). When exposed to moisture, or with water, the adhesive broken, so the layers of plywood are not peeling, splitting. Currently, there are two types of WBP glues: melamine glue and phenolic glue. Both types of products are of excellent quality. Plywood using melamine glue can be soaked in water for 4-8 hours without being separated. For phenolic glue, it is 24-48 hours.

4. Differences between marine and conventional plywood
Whether used as a floor or an extra layer, marine plywood is more resistant to rot and warping than regular plywood. It resists moisture from steam and can prevent the absorption of stagnant water. It even holds well against boiling water! It makes it a great option as a liner for the kitchen or bathroom floors.
Marine plywood is also stronger and more durable than regular plywood. Marine plywood has five or more layers bonded together with a waterproof adhesive, allowing it to bear heavier loads and repel moisture from its core. Therefore, you can use a thinner sheet that will have the strength of thicker conventional plywood. The extra strength and durability make marine plywood an excellent base for heavy flooring materials, like ceramic tiles.
