Please pass this article to anyone you know who is about to stain or paint a wooden deck. You may be ready to stain your own deck. It may be your neighbor. It may be a contractor you are hiring to stain your deck. Why should you care what you, your contractor, or your neighbor uses on his deck?
We know what works, and we know what doesn’t from over 20 years experience in wood care. We have used and tested countless wood coatings, and only a few products available really last. It seems to be a race among some retailers as to who can sell the cheapest per gallon price. Homeowners bear the brunt of these choices in disappointing results, and costly frequent maintenance. Before choosing a wood care product, ask how often it requires re-coating, and what chemicals are involved in the process.
You should consider kiln dried wood, or be sure to dry treated wood for 30 days before you build your deck. Why would we build a deck with wet wood, knowing it wants to warp and twist, and split, as it rapidly and uncontrollably dries out once you unbundle it? Read More. Simply order your wood a couple of months before you plan to build your deck. Have it unbundled and re-stacked, allowing air movement between the boards. Use thin wood strips or rack wood, and cover from the sun, best indoors if space allows. Wood can be slowly dried (sometimes with dehumidifier) and is usually dry in about 30 days.
The bottom side of the board should be sealed before installation.Backside coating is an important step to get a good looking, low maintenance, low cost deck care solution. If wood is near the ground, and the sun beats down on the top surface, moisture is drawn from the cool ground underneath up through the bottom side of the boards. This causes expansion and contraction of the wood, leads to cupping of the boards, and greatly reduces the long-term performance of any coating. Even elevated decks will absorb moisture through the uncoated backside, even if the lumber is "pressure-treated". More

For new wood, we have found One TIME can be applied on new wood dried about 30 days, sometimes sooner. Many Stains and wood coatings fail due to original application on wood that is either too wet, or wood that is too polished from the milling process. We like the ability to coat the topside quickly after building the deck to prevent UV damage. Smooth Cedar and Redwood should be weathered a bit before applying One TIME.
If you are building a new deck, get your wood dry before you build, prepare the wood , sand it if it is slick or mil-glazed, choose a proven solution, coat bottom and saw-cuts, install wood, coat the top, and maintain as directed.
If you have a deck with existing failed coating, you will likely need to strip and possibly sand the surface for proper performance of the new stain or coating.
