Update 2019 for Composite Sealer Reviews
Here at DeckStainHelp.com, we take pride in the fact that we have become the Internet’s number one resource for true, honest deck stain reviews. Composite decks contain a mix of plastic and wood and are prone to mold and mildew growth just like wood decks, so you should choose a high-quality composite sealer to protect your finished project. If you have used composite sealers in the past, or if you are using one for the first time this year, we appreciate your input, so feel free to leave a comment below and pictures of your completed projects if you have them.
You may not think a composite deck needs to be sealed or protected. It may not be as susceptible to the elements as a wood deck, but the truth is that a composite deck is prone to many of the same problems. Composite decks are normally part wood and part plastic so they are prone to mold, mildew, fading, and graying due to both sun and water damage. To help increase the longevity of a composite deck it should be protected with a composite deck sealer.
