There are certain steps to take when protecting and preserving a wood surface like a deck, fencing, wood siding, roofing or a log home. The wood needs to be cleaned thoroughly and prepped prior to staining. A wood prep consists of cleaning the wood followed by a neutralizing process to open the wood pores to ready them for stain. Once you have completed a proper wood prep there is a certain amount of time the wood needs to dry before applying stain.
The amount of time necessary can vary from surface to surface. Weather, humidity, sun exposure, wood age, type and porosity can all affect the dry time needed. Although the wood dry time may vary there are some basic guidelines. Most wood surfaces will be dry enough for a stain application 24-48 hours after the wood prep. If you want to get technical you can buy or rent a moisture meter. Stick the wood in several different areas to get an average moisture reading. Most wood stains can be applied once the moisture level is 12% or below.
Without a moisture meter, waiting a couple of days is typically sufficient. Dry time after prep before applying stain should be reset if the deck gets rained on. Rain during the drying window will delay the stain application. Once the rain stops the wood needs to dry another two full days on average. Wood surfaces in full sun during warm weather and a nice breeze may only take one day to dry while a deck in full shade may take longer. If you are unsure it is best to wait a couple of days than to apply stain to early.
Not waiting the appropriate dry time after prep before applying stain can actually trap moisture in the wood, which can cause mold and mildew infiltration. Applying stain over wood holding too much moisture will also jeopardize the longevity and performance of the wood stain. Therefore it is best to wait too long than to apply stain too soon. On average you need three days of dry weather after prep work has been completed. Two days of dry time and dry weather on the third day during the stain application assuming it can be accomplished in a single day.
My deck is one year old and not too dirty. Is a garden hose powerful enough to remove the cleaner and brightener?
You will need either a pressure washer or you will need to heavy scrub. Rinsing only with a hose will not work to prep. You are not just removing the cleaner and brighener but the dirt, grime, and oxidation that has occurred in the past year.
You have responded that I should totally remove 4-year old Behr semitransparent stain before using your stain. How would you recommend I totally remove previously applied semitransparent stain?
Stripper and pressure wash. Wood brightener after.
My deck in Cincinnati is 10 feet off the ground and has over 200 spindles and many stairs to ground level. After waiting 2 days after prep, how long will the pores be open enough to stain, because it will take me a few days to finish the staining by myself. Also, birds pecked some holes in three places in the deck to remove some carpenter bee larvae. What is the filler to put in those holes before staining? Also, I used Behr semitransparent “natural” stain 4 years ago. Which of your stains should I now use?
Try to stain within 2 weeks of prep. Wood filler will not work on exterior wood. Make sure to remove the Behr fully during the prep. Once removed, use the Armstrong Clark stain.

If you wait, you will need to reprep in the Spring with a deck cleaner and a wood brightener.
