Backyard deck coating in a rich redwood finish with railing

What a deck coating does

Sun and rain are relentless on a deck. Left unsealed, boards gray, crack, splinter, and eventually rot. Our deck coatings lock out moisture and UV, restore rich color, and keep the surface smooth and safe for bare feet.

The damage happens in a specific order, and it is worth understanding because it explains why timing matters. UV breaks down the surface fibers of the wood first, which is the graying everyone notices. Then water gets into those opened fibers, swells them, and drives the checking and splintering. Once water is moving freely in and out of a board with every rain and every hot afternoon, rot follows, and by then a coating is no longer the fix — carpentry is. A deck caught before that point can be brought back. A deck caught after it gets replaced board by board.

  • Waterproof protection. Moisture stays out of the wood, so rot never gets a foothold.
  • UV defense. No more graying and fading every summer.
  • Smooth, splinter-free finish. Safe for kids, pets, and bare feet.
  • Instant curb appeal. A coated deck looks freshly built.

Used on wood decks, composite decks, porches, stairs, and railings.

Prep

Prep is what decides whether the finish holds

Wood is the least forgiving surface we coat, because it moves, it holds water, and it usually has something else on it already.

The wood has to be dry

Sealing a board that is still carrying water traps that water inside it, and the finish comes off in sheets as the board dries out underneath. This is the most common reason a deck finish fails in its first year, and it is entirely avoidable by not rushing the work.

Whatever is on there now comes off

Old stain, failing sealer, mill glaze on newer boards, and the gray, degraded surface fibers on older ones all have to go before anything new is applied. Coating over a failing finish means the new work is only bonded as well as the old work was.

Boards, fasteners, and railings first

Popped nails, loose boards, split ends, and wobbly railings get addressed before the finish goes on. A coating does not hold a deck together, and it certainly does not hide a fastener that is working its way back out.

Protect it now or rebuild it later

Coating a deck costs a fraction of tearing it out. The window for that choice closes once water is moving freely through the boards.

Start to finish

What the job looks like

No demolition, so the house stays livable and the yard stays usable.

  1. Walk the deck with an owner

    We check the condition of the boards, the railings, the fasteners, and whatever finish is already on there, and tell you honestly whether coating is the right call. Free, no obligation.

  2. Written proposal

    System, color, scope, schedule, warranty, and itemized pricing, in writing before anything is committed.

  3. Clean, strip, and repair

    The old finish and degraded surface come off, and boards, fasteners, and railings are put right before anything new goes on.

  4. Let it dry

    Wood has to reach the right moisture level before it is sealed. We wait for it rather than working around it, because this is the step that decides whether the finish lasts.

  5. Coat, cure, and walk it with you

    The finish goes on across the deck, the stairs, and the railings, and we confirm the cure window before furniture goes back on.

What is warrantied, and what it costs

Every surface we coat carries a workmanship warranty, from 1 to 15 years depending on the surface and the system specified. The exact term for your deck is spelled out in writing in your proposal. If our workmanship fails, we make it right.

Coating a surface typically saves 50 to 70% against a full tear-out and replacement, and coating projects generally start around $1,500 and up. Exact pricing is itemized in your written proposal. Payment plans are available — see payment options.

We are a licensed and insured, family-owned LLC based in the Kansas City metro. The owners are the people who walk the deck, write the proposal, and answer the phone.

Common questions

Deck coating FAQ

Have a question we haven't covered? Call or text us and ask.

Request a Proposal
My deck is already gray and splintering. Is it too late?

Usually not. Graying is surface damage, and the degraded fibers come off during prep to expose sound wood underneath. Splintering is the same story a stage further on. What genuinely ends the conversation is rot, structural movement, or boards that have gone soft — and if that is what we find, we will tell you rather than seal over it.

Can you coat a composite deck?

Yes. Composite decks, porches, stairs, and railings are all surfaces we work on. Composite is a different substrate from wood and gets prepared differently, which is one of the things the walkthrough sorts out before the proposal is written.

What if it rains during the job?

We wait. Wood has to be at the right moisture level before it is sealed, and coating a wet board traps that water underneath the finish. Weather delays are part of exterior work, and building them into the schedule honestly is better than delivering a finish that peels in its first season.

Do the railings and stairs get coated too?

They can, and in most cases they should — railings and stair treads take as much weather as the deck surface and are usually the first things to look tired. Whatever is included is written into the scope in your proposal, so there is no ambiguity about where the work stops.

How long does a deck take?

Most residential projects are measured in days rather than weeks, and because there is no demolition, the house stays completely livable throughout. The finish needs a cure window before furniture goes back on, and the exact schedule is confirmed in your written proposal.
