Cut to a 6 x 18 ft coverage size this marine boat carpet uses a 32 oz per square yard face weight with a waterproof latex marine backing to hold up across fishing boats pontoons docks and lakeside porches. Anti Uv treated fibers resist fading after months of direct sun exposure and the tight cutpile stays secure underfoot even when soaked with water. The waterproof backing stops moisture from wicking into plywood subfloors which extends the life of the deck below.
