New Deck: Sealed or Stained?
Being the proud owner of a new deck can be exciting, but if not cared for and properly maintained, especially in the beginning, you could be signing yourself up for a lifetime of headaches and costly repairs, instead of the enjoyment and relaxation you envisioned. As with any home improvement project, the more informed you are as the homeowner when it comes to proper installation, maintenance, and general upkeep and care, the more likely you are to have a successful addition to your home to enjoy for many years to come. And when it comes to a new deck on your home, you don’t need to be a contractor or lumber expert to learn some easy, but incredibly valuable tips to ensure the beauty, stability, and strength of your wood deck for the entirety of its lifetime.
🪵 Should New Wood be Sealed or Stained?
One of the biggest misconceptions about new decks is that they don’t need to be cleaned prior to staining. This couldn’t be farther from the truth. Think of it like wanting to put on a new outfit, but rolling around in a big dirt pile before putting it on. Doesn’t make much sense, does it? And you certainly won’t be left with the results you were hoping for. Every piece of new lumber has a coating of mill glaze on it that protects it throughout the production process. Luckily, this coating can, and should be, removed before staining or sealing your new deck. Washing the wood with a deck cleaner or leaving it outside to weather for several months are the best options when it comes to properly prepping the wood before treatment.
New deck wood is also very high in moisture content. You may have noticed how heavy a new piece of wood is compared to a piece with more age to it, and that weight comes from the moisture it’s holding within. Sealing a deck too soon can trap this moisture within the wood, resulting in mold, mildew, and even wood rot.
⏰ Timing is Everything
Depending on the brand of stain you’ve purchased to use on your new deck, you must allow new wood to “weather” or age for several months before washing and staining it. Some even believe that a new deck must weather for an entire year before you can stain it. In most cases though, this is a myth. And truthfully, most of the water and sun damage homeowners encounter occurs to unprotected wood within that first year. Ideally, you want the moisture content to be about 10-12 percent or less before cleaning and sealing the wood. This can be easily checked with a moisture meter, available for purchase at your local hardware store. During the hot days of summer, if a deck has plenty of sun exposure, it may only take new wood 3 months or so to dry enough for sealing.
🧼 Cleaning a New Deck: Step 1
Once you have determined that your new deck is ready to be protected, the first step is to wash the wood with a quality deck cleaner. The sodium percarbonate deck cleaners, available in the powder form, are very effective and will make your job easier. These are eco-friendly, non-chlorine powders that break down organic buildup like mold, mildew, algae, and gray weathering residue on both wood and composite decks. Following the mixing ratio instructions on the packaging, apply the deck cleaner with a pump sprayer and use a stiff brush or pressure washer to clean the wood. (Pro-Tip: After mixing, run the mixture through a cheesecloth or fine mesh strainer to prevent any clogging in the nozzle of the pump sprayer.) Remember to rinse the deck thoroughly after properly saturating and scrubbing it with the deck cleaner, to remove any residual solution left behind. This process will remove any dirt, grime, or mill glaze present on the wood and eliminate any graying that has occurred.
✨ Brighten a New Deck: Step 2
Following the cleaning process, it is recommended to apply a deck brightener. Most deck cleaners contain caustic soaps that will darken the wood. This is why properly rinsing the cleansing agent after use is important, especially to minimize the severity of the wood darkening. Applying a deck brightening product will neutralize the cleaner further and enhance the beauty of the wood. Deck brighteners also restore the proper pH levels in the wood so the new deck stain will pe*****te properly.
🖌️ Staining a New Deck: Step 3
It is important to allow your wood deck to dry for a couple of days before applying the deck stain. Before anything else, use a leaf blower or broom to clean the deck of any debris that may have fallen on it. It is imperative that you use a quality deck stain on new wood. This is one of those moments where “you get what you pay for” becomes unarguably true. Newer wood is denser than aged wood, and only a quality deck stain will pe*****te the wood pores to provide maximum protection. For proper application and coverage, follow the directions provided on the stain can packaging. As tempting as it may be to immediately pull out the deck furniture and fire pit for a relaxing evening, admiring your hard work, it is crucial to allow the deck stain to cure for several days before use. DON’T TOUCH IT!
Prepping a new deck for stain is not hard, but it is crucial to the deck’s stability and longevity. Knowing how and when to start the process is the key!
