Clean, Clean, Clean

As far as I'm concerned, no there's no sense in even bothering with wood deck stains if they'll just be applied to a dirty, unprepared surface to start with. Without a perfectly clean and prepared wood slate to begin with, the chances of the job turning out badly are pretty high. If the deck isn't in too bad of shape to start with, usually a mild soap and water solution applied with a broom and rinsed thoroughly by hose will do the trick. Be sure the deck is completely dry before proceeding.

Follow Wood Deck Stain's Directions

Depending on the wood stain's manufacturer and solution, there can be countless different ways to apply the wood deck stain properly. Be sure to follow the appropriate steps for the exact type of surface of your deck. Also, pay close attention to the time it takes the deck stain to dry before recoating or use. One trick that always helps to assure consistency is to mix all of the stain together before applying - this way any inconsistencies between different batches will blend.

Applying Wood Deck Stains

This step is where everybody seems to start asserting that their way is the best. While I can't vouch for the rest, this is my favorite way to apply wood deck stains. It takes a little bit longer than some of the other application methods, but the results are worth it. And I should mention that I have a ton of experience with this. Here goes:

First things first, start at a far corner of the deck and work backwards to avoid boxing yourself in as you go. Start by rolling the stain on with a medium nap roller cover. Apply the deck stain to about two or three boards in width at a time, and try to only apply it so you'll be stopping at the seams lengthwise.

Once you've rolled the wood deck stain out for the first small section, go back with a medium width quality paint brush and work the stain in to a smooth and even finish. Depending on if your stain is oil-based or water-based, be sure to use the correct brush for the job. Now, just repeat this process until the entire deck is finished. If you have a partner to help with the job, having one person rolling and one person brushing really gets the staining done quickly.

With wood deck stains, second coats are not always needed. Use your best judgment, but try not overdo it. Applying too much wood deck stain will cause a bad, murky finish. Be sure to let the stain dry for a couple of days before placing any furniture or other objects back on the deck.

That's all there is to applying wood deck stains!
