Does WPC Wood Resist Water?

Is WPC wood water-resistant or waterproof? Concerning WPC wood, many people are perplexed. To learn more about WPC wood, see this article.

Does WPC wood get damaged by water?

Water travels up and down a tree’s length in the tissues that make up the wood. Even after the tree has been cut down and its trunk has been sawn into boards, these fibers continue to store water. In actuality, this moisture content affects the proportions of a piece of cut timber. A wood board that is dimensionally stable has a moisture content of about 20%. An issue arises when the moisture content is greater than 30% of the weight of the board.

The fibers begin to split if the water is allowed to remain inside of them. This process can be sped up by the expansion of retained water during a freeze. This free water subsequently creates the conditions for the growth of fungus and other microbes that degrade wood.

How can I pick WPC wood that is water resistant?

A waterproof material differs greatly from one that is water-resistant. Water infiltration can be tolerated by materials that are water resistant. Such a material will somewhat, but not entirely, resist water infiltration. Similar to this, because water cannot easily penetrate WPC wood decking, it is water-resistant. Water won’t simply seep through a WPC wood decking board if it is placed adjacent to a dock or a pool. When fully submerged in a pool or pond, this material won’t absorb water, in contrast to waterproof materials. A water-resistant material may absorb water when fully submerged even if water cannot easily travel through it, now that the distinctions between the two have been made evident. A waterproof substance, on the other hand, won’t absorb water, even when buried deeply.

How can I waterproof my WPC wood?

Starting with the decking boards at the top, waterproofing is applied. Trex-brand WPC boards don’t require additional waterproofing or sealing. Trex decking is made of 95 percent recyclable materials, so it won’t rot or warp and won’t need painting or staining. When building a wood deck, it is usually good to provide additional protection. Vinyl membranes, coatings, and sealants are employed most frequently in these methods.

  • Sealers

If you use wood boards, the wood must be properly sealed and preserved. By preventing water from reaching the porous surfaces of the wood, a clear sealer may reduce the risk of rot. The water on your deck should bubble up like a waxed car. If not, it’s most likely time to reseal. Most builders suggest sealing wooden deck boards every one to three years. For more information, refer to the sealant’s manufacturer’s directions.

  • Coatings

Because deck coatings are a thick material that are used to refinish and waterproof a deck, some people believe coating is the greatest approach to safeguard the deck. They can be made of latex, enamel, acrylic, liquid rubber polyurethane, or other materials. Before applying a new coating, the surface must be cleaned. The finished result can be slip-resistant and available in a variety of colors, so the preliminary work is beneficial. Not everyone likes coating since it may be difficult and complex. To apply a uniform coating, you can use a brush, roller, or spray. In addition to the time required for cleaning and application, the coating needs time to dry and adhere to the deck.


Although not waterproof, WPC wood is water resistant. Your floor may be harmed if the water level goes beyond the limit. As a result, you must guard against too much water getting on your WPC wood.
