Composite Wood Decks with Defy Composite Waterproofing Sealer and Cleaner

Many homeowners are going with the composite type decks these days. Composite decks are usually made from a material containing some wood, plastic or another type of durable products. Though composite decks can be marketed as “maintenance free” they really aren’t. Anything that is exposed to the elements will degrade over time if it is not protected.

Defy Composite Deck SealerThe good news is that a composite deck can be protected just like a wood deck. Using a stain like Defy Composite Sealer that will penetrate the dense composite material is the key.

The surface can be cleaned and treated with a sealer to block out the sun’s damaging UV rays and moisture. When these types of decks are not protected they can gray out, warp, split, and collect mold and mildew.

Before staining a composite deck it first has to be cleaned. A good composite deck cleaner Such as the Defy Composite Cleaner should be applied onto the surface. The composite deck can then be pressure washed or scrubbed with a stiff brush to remove any dirt, grime, graying, or mold/mildew. Once the surface is clean it can air dry for a day or so.

Be careful not to use just any type of wood sealer on a composite deck. The material is very dense and most stains will not penetrate it very well. A sealer like Defy Composite Sealer is specially formulated to penetrate very dense hardwoods and also works very well on composite decks. It will dive into the surface of the deck and help shield against the sun and unwanted moisture.

Apply Defy Composite Deck Sealer using a brush, roller, or sprayer. Apply one board or section at a time. Apply only as much Defy as the composite will soak up. Wipe or back brush any excess stain so as to not leave any puddles, runs, or drips.

Maintaining a composite deck is made easy with Defy. Keep your composite surfaces looking like the day they were installed and enjoy them for many years to come.

Defy Composite Deck Sealer can be used on all composite wood brands such as: TREX, Fiberon, Azek, TimberTech, etc. It should not be used on solid plastic decking.

      No, it will seal the wood but it is not possible for a clear sealer to "enhance" the color.

    Deck is approximately 500 sq. ft I applied gallon and a half. I left no “holidays in application” there are no  shiney or white spots. I’m going with my “gut” will apply second coat. It took three days to clean without power washer. Is there a possibility I applied to thin? Thanking you Happy Sunday

    Can you apply on deck during hot and humid days? Is it best to make sure there’s not rain during first day or so after applied?
    • We will reply to your comment shortly.
      thesealerstore · 07/02/2019
      Deck temp needs to be below 90 so it does not flash dry. It can take rain in 6 hours after it dries.

    Last Fall I power washed my composite deck before applying product with a sprayer and deck brush, careful to follow directions. I have some patchy areas of 'white' which is very noticeable on dark brown deck boards. Cause?? How to remedy?? Disappointed in final appearance..

      thesealerstore · 04/05/2019
      It could be many things. It could be due to the prep, the wood itself, or over application of the sealer. Hard to say what the reason is or how to fix without more details. Do you have a picture?

        Jeffrey · 05/17/2019
        I also have some white areas from the over application, this was applied with a sprayer, and is just dry for 24 hours. Is there a remedy?

          thesealerstore · 05/17/2019
          It may go away once fully cured in a few days or week. I would wait and see.

    I used the Deyf composite cleaner and then used your deyf composite clear sealer. I am still seeing white specks on boards and I think I need to strip it down now and used some solid stain to restore to an acceptable look. What do you recommend to strip off the Defy sealer?

    Mike G · 03/30/2018
    Is the Composite Decking Sealer the same as the Brightner? I was told you could purchase a concentrate brightner to enhance to surface shine. Sounds like the Sealer is the same product. Can you confirm?

    Thanks,

    Mike G

      thesealerstore · 03/30/2018
      Hello, not they are not the same, not even close. A wood brightener would not enhance the shine either.

    CAN DEFY SEALER BE USED ON TREK CAPPED DECKING?

    boards capped on top and sides but not bottom want to seal bottom
    • We will reply to your comment shortly.
      thesealerstore · 01/21/2018
      As long as the bottom is composite and porous for the sealer to soak in, then yes.

    Is compositedesck the same as a trek deck
    • We will reply to your comment shortly.
      thesealerstore · 01/21/2018
      Not all Trex products are composite but some are. For the sealer to work, the decking must be porous.

    Just finished cleaning our composite deck with Scott's Outdoor Cleaner with Oxy Clean. Looks pretty good. Thought there might be a better solution than scrubbing and power washing every year and found your product. Should we redo the cleaning process with your cleaner before applying the composite sealer or is the Scott's clean ok?

    Probably will be okay as long as it is clean.
