Staining Composite Decks in 2022

We here at DeckStainHelp.com thank you for your continued support as we continue to be the internet’s number one reference for all things wood deck restoration related. Composite decks have become popular over the last few years, so here we outline some tips for staining them. As always, we appreciate your input, so feel free to leave a comment below.


Composite material decks have become very popular among homeowners in the past few years. They come in many different designs and colors. Most people believe that a composite deck is maintenance free but that is not true. Like any surface exposed to Mother Nature, composite decking is prone to fading, graying, warping, and so on. To stop these negative effects a composite deck stain should be applied. Staining composite decks help block out color fading UV rays and damaging moisture.

To stain a composite deck the surface must first be completely cleaned. With the use of a pressure washer or scrub brush and a composite deck cleaner, all the dirt, mold, mildew, and graying should be washed away. Mildew is a common occurrence on composite materials. Because most composite decking consists of wood and plastic it is prone to mold and mildew. It is important to remove any mildew before staining the deck so mildew is not sealed in and trapped below the surface.
Once the surface is dirt free it will be ready to accept a new stain. Use a quality composite deck stain that penetrates well. Look for a stain that helps fight against UV fading and discoloring. Composite deck stains with mildewcides or inhibitors are a plus. Any stain containing zinc particles will also naturally fight against mildew. Apply the composite deck stain using a brush, roller, or stain pad. Do not over-apply.

Try to stay away from film forming or solid deck stains. These can begin to flake and peel away from the surface after a few months. They are also more prone to mildew problems because they create a film atop the surface that may trap moisture. To keep a composite deck looking good, rewash the deck every couple of seasons and apply a maintenance coat of stain. This will help ensure a clean, attractive composite deck for many years to come.

Update for 2022 Staining Composite Decks

We recently prepped and stained a very old and dirty Trex deck in Spring of 2021. We applied the penetrating TWP Semi-Solid Pro-Series to the Trex, and it turned out outstanding! Looks brand new and the TWP soaked deep into the composite decking with no issues. We highly suggest the TWP Semi-Solid if you are looking to add some color or stain to your old composite decking.

TWP Semi-Solid Pro Series

Prep Materials: Restore A Deck Cleaner Kits

Color Used: TWP Semi-Solid Mount Rushmore

Coverage: 1 coat was applied. 4.5 gallons were used. Coverage was about 200 Sq Feet per gallon.

TWP Semi-Solid Pro-Series Review: TWP Pro-Series Semi-Solid

I have a ChoiceDek that is 15 years old. It looks bad, dark mildew throughout. Composite deck cleaners have not helped. Is there anything that I can do? I saw that it can be stained but considering that I cannot get the mold off, is it even worth doing or should I just bite the expensive bullet and replace the boards?

Paint was spilled on our composite deck. What is the best remover? I am sure that it will leave splotches of a lighter color. What type of deck stain should I use to get a more complete color?

I have the original Trex Composite Decking which is about 20 years old. Can I use the TWP Pro-Series-Semi-Solid Stain/Sealer? Or would you recommend Defy Composite Sealer? When I power wash the deck the color is still fairly good.

I’m confused now. I have a five year old composite deck. I hate the saddle brown color and am now also going to add on to it at a different height. So can I stain it? Can I use a semi solid stain? Something else? Thanks very much.

Why is in not possible to fix the chalky white caused by goof off.
We had our house painted and contracted taped paper on deck during prep. The glue from tape would not come off our trex deck contractor used goof off ruining the deck. He has offered to stain Deck.
So would like to know why goof off damage can not be fixed?

I have one of the older(not encapsulated) Trex Decks with soaked in grease stains that cleaning with vinegar and baking soda did not remove. Is there any hope of removing the stains or will one if the composite deck stains hide the grease stains?

I just installed pricey AZEK ARBOR, PVC decking… Brazillian Walnut colot… ($100 per board!) – I need to revitalize the finish in some spots. Surface is damaged. Here’s what happened… I tried to remove some latex paint drops using popular “Goof-Off” spray… BIG MISTAKE! Every place I wiped with Goof-off is now chalky white. Help!!

I have a 2002 Timbertech deck that is very weathered. What is the current best stain brand for this type of deck and should you use oil or water based stain?

I recent purchased a home with light gray Trex decking. It’s at least 10 years old and looks weathered (even a bit rough) with small black mold spots. A painter told me to clean it and to use a translucent stain. However most companies stains for composite decking are solid stains. Which is best? Water or Oil base?
Multi coats?

My dog has made a scratchy mess of my Timbertech deck. Will staining help cover the scratches and will the new stain scratch easily? I am trying to figure out if it is worth the time and effort. Thanks!

Not true!!!!! Use Benjamin Moore Arborcoat Solid Stain. Any good paint or stain suitable for PVC will do the job. Light sand first than paint or stain. It works!
