Why does my deck fade so much sooner than my fence?

Because it faces the sky. A deck board takes the sun from morning to evening at close to a right angle, holds rain and sprinkler water on its surface instead of shedding it, and is walked on every day. A fence is vertical, shades itself for part of the day and is never scuffed by shoes or chair legs.

Can a deck be stained in the middle of summer?

Yes, if the day is planned around the sun. Work starts early or follows the shade across the deck, and boards that are hot to the touch wait. Stain applied to a hot board dries on the surface before it can soak in, which leaves lap marks and a finish that wears through early.

How long before we can walk on the deck or put the furniture back?

It depends on the product, the temperature and the humidity, and the label gives the range. Light foot traffic usually comes well before heavy furniture, planters and rugs. Ebenezer tells you the plan for your deck before he starts, so you can arrange the barbecue around it.

How do I know if my deck is ready for new stain?

Sprinkle a little water on a few boards in the sunniest part of the deck. If it beads and sits, the old finish is still working. If it darkens the wood and disappears within a minute or so, the wood is thirsty and ready for preparation and a new coat.

Staining a Deck in the San Diego Sun

A deck in San Diego takes more sun and more wear than any other wood around the house, so it needs recoating sooner than a fence or a pergola. Stain it when the boards are dry and cool to the touch, in the shade of the day rather than the full afternoon sun, and work it into the gaps, end grain and stair treads, not just across the tops.

Of all the wood around a San Diego home, the deck has the hardest life. Siding, fences and gates stand upright and shed water. A deck lies flat and faces the sky, so it takes the sun at close to full strength for most of the day, it holds every drop of rain and sprinkler overspray on its surface, and people walk across it in shoes, drag chairs over it and roll a barbecue across it. That combination is why a deck needs attention well before the rest of the wood on the property does.

In the inland valleys the sun is the dominant force. A deck in El Cajon or Santee can sit in direct light from late morning until the sun drops behind the hills, and in August the boards get hot enough to be uncomfortable barefoot. Ultraviolet light breaks down the surface fibers and the binder in the stain, and heat opens small checks along the grain.

Why does a deck need restaining sooner than vertical wood?

Because a horizontal surface collects everything a vertical one sheds. Water sits on a deck board instead of running off, sun hits it at a steeper angle, and foot traffic grinds away the top layer of stain where people walk most. The traffic path from the back door to the steps always wears first.

That last point matters when you look at your own deck. If the finish has gone gray or patchy along the path to the stairs but still looks reasonable under the table and along the rail, the deck is not failing evenly, and the preparation should not treat it as if it were.

Reading the boards before anything is applied

Sprinkle water on several boards, including the sunniest part of the deck and the traffic path. If it beads, the existing finish is still repelling water. If it darkens the wood and soaks in within a minute or so, the wood is open and ready to take stain once it is prepared.

Ebenezer also looks at things a homeowner tends to walk past:

End grain. The cut ends of boards drink water like a bundle of straws. Ends that are splitting or darker than the rest of the board have been taking on moisture for a while.
Fastener heads. Nails that have backed out, or screws ringed with dark staining, tell you water has been sitting around them.
Stair treads and the bottom step. Treads take the most wear on the whole deck, and the bottom step often sits closest to wet soil and sprinkler spray.
Soft spots. Pressing a screwdriver point into a suspicious area separates weathered wood from rotted wood. Rot is a repair conversation, not a staining one.

Cleaning and brightening the wood comes next, and it is a subject of its own, covered in wood cleaners and brighteners. What matters here is that stain soaks into clean, open wood fibers and sits on top of dirt, mildew and gray dead fibers, so no deck is stained before it has been properly cleaned and allowed to dry through.

Why does the time of day matter so much?

Stain needs time to soak into the wood before it dries. On a board that is hot from the sun, the solvent or water in the stain flashes off at the surface first, so the color dries in a skin on top instead of penetrating. You get lap marks where one pass overlaps another, and a finish that wears through early.

So the working day on a deck follows the sun rather than fighting it. In practice that means:

Start where the shade is. Early morning, once any dew from the marine layer has dried, the boards are usually cool enough. In La Mesa and the South Bay the morning damp can linger, so the deck has to be dry to the touch and dry underneath, not just on top.
Move with the shade. As the sun comes round, work shifts to the parts of the deck the house or trees are still covering.
Stop before the full afternoon sun. On the hottest inland days the sunniest section may be left for the following morning rather than rushed.
Watch for wind. Santa Ana days bring hot, dry wind that dries a finish too soon and blows dust and leaves into it.

The label on the can gives a temperature and humidity window. Ebenezer works inside it, and on San Diego decks that usually means working short of its upper end.

Getting stain where the wear actually happens

A deck is not a flat board. The gaps between boards, the edges of each plank, the cut ends, the stair stringers and the underside of the handrail all take weather, and the gaps in particular collect leaves and dirt that hold moisture against the wood.

Stain is applied a few boards at a time along their full length, so each board is finished from end to end without a dried edge in the middle. Whether it goes on by brush, pad or sprayer depends on the deck and on your preference, but on most decks it is worked in by brush afterwards: back-brushing pushes the stain into the grain and the edges, lifts any puddles before they dry glossy, and makes sure the gaps and end grain get their share. End grain often takes more than the face of the board, because it is so much more absorbent.

Excess stain is not a bonus: whatever the wood cannot absorb dries tacky or shiny and wears off in patches. A good deck finish looks as if it is in the wood, not on it.

Drying before you use it

Once the stain is down, the deck needs time before it goes back into service. Light foot traffic comes first, and heavy planters, outdoor rugs, furniture with narrow feet and the barbecue come later, because they press into a finish that is still curing and trap moisture under them. The label gives the range. Ebenezer tells you the plan before work starts, including which part of the deck is out of use on which day, so nobody is surprised on a Saturday.

When the deck is part of a bigger job

Most decks sit against a house that has its own paint, trim and doors, and the deck is often stained in the same project as the exterior. Ebenezer manages every project personally, so a deck alone and a deck alongside a repaint are both welcome conversations. No job is too small.

If you are not sure what finish your deck needs, or whether the boards are past the point where stain will help, that is exactly what the visit is for. Read more about wood staining, about painting in El Cajon or Santee, or ask for a free estimate and Ebenezer will walk the deck with you, run the water test on your own boards and tell you plainly what it needs.
