What kind of plywood is waterproof?
Exterior plywood is weather (and water) resistant, so it’s strong enough to be used outside and also in areas that are exposed to water and humidity, like a garage. This type of plywood, often made from Douglas fir, is made stronger by adhering its layers with a waterproof glue.
Which plywood is waterproof?
CDX is made of rough, lower-quality wood that is heavily treated for water resistance and is ideal for things like roof sheathing. Marine-grade plywood is much smoother and higher quality and has the best waterproofing of any plywood.
