Should I resurface or replace my pool deck?

Resurface when the slab is solid and the trouble is on the surface: wear, scaling, pitting, stains, a slick finish or hairline cracks. Replace it when the slab itself is moving: wide or stepped cracks, sinking or heaving sections, or water that runs toward the pool. A thin resurfacer cannot stop old cracks reappearing, so get both options quoted in writing.

Step by step

Read when to stop and call a pro, further down this page, before you start.

  1. Step 1: Look at the deck after rain or a hose-down

    Note where water sits and which way it runs; puddles and flow toward the pool point toward replacement.

  2. Step 2: Sort surface wear from slab damage

    Rough, scaled, pitted or stained concrete is a resurfacing candidate; sunken or tilted sections are not.[1]

  3. Step 3: Measure the cracks

    Measure the width of each crack and run a finger across it to feel whether one edge is higher than the other.

  4. Step 4: Check for coatings

    Find out whether the deck was painted or sealed, since the resurfacer is applied only to bare concrete.[1]

  5. Step 5: Test the grip

    Walk the deck wet in bare feet and note any slick sections.

  6. Step 6: Ask for both options in writing

    Request written quotes for resurfacing and for replacement from licensed contractors, using identical specifications.[4]

  7. Step 7: Check the licence

    Look up each contractor on DPOR before you sign.[4]

Fix the surface or rebuild the slab

Resurfacing renews the top of a concrete pool deck; replacement renews the slab. So the question is where the problem lives. Rough, scaled, pitted, stained or slick concrete on a slab that is otherwise flat and solid is a resurfacing job. A slab that is cracking wide, moving, sinking or draining toward the pool is a replacement job, because a coat that thin cannot hold it still.

QUIKRETE Re-Cap Concrete Resurfacer is designed to provide a new, durable, and wear-resistant surface over worn or scaled concrete.[1] It can be applied from a feather edge of 1/16 inch to 1/2 inch thick.[1] That range tells you what resurfacing is: a skin.

Resurface when

  • The concrete is worn, scaled or pitted but sits flat and tight.
  • Cracks are hairline and the two sides are level.
  • The finish is slick and you want a textured, slip-resistant surface. A broom finish is applied when the surface is thumb print hard.[1]
  • Drainage is already right and water leaves the deck away from the pool.

Every one of these assumes the slab is not moving. Repairs to damaged concrete must be made before resurfacing can be initiated.[1]

Replace when

  • Cracks are wide or one side is higher than the other.
  • Sections have sunk, tilted or heaved, or the deck has pulled away from the pool.
  • Water puddles on the deck or runs toward the pool instead of away.
  • The surface is crumbling all the way through, not just flaking at the top.

Los Angeles County's guide for inspectors of public pools lists these as deck problems: major cracks, uplifting, broken or missing deck tiles or deck drain covers, a deck that is not slip-resistant, and water puddling on the deck.[2] A home pool is not inspected that way, but the list is a fair checklist for your own walk-around.

Why a thin layer cannot fix a moving slab

Cracks come through. Old cracks can reappear due to movement in the base concrete.[1] The manufacturer adds that reflective cracking into the new surface cannot be completely prevented, especially if the slab does not contain adequate control joints or if slab settlement occurs.[1] If the slab is settling, a new surface just gives the same cracks a fresh place to show up.

What preparation involves

Good resurfacing is mostly preparation. Old concrete must be rigorously cleaned to ensure proper adhesion, including cleaning with a 2500 PSI pressure washer.[1] The data sheet says to apply only to bare concrete, and not to painted or sealed surfaces.[1] If your deck carries an old sealer, ask how it will be taken off.

Weather matters too. The temperature of the air and the concrete surface should be in the range of 50 to 90 degrees Fahrenheit,[1] and it is best to wait 8 hours before allowing foot traffic on the surface.[1] On a deck you will want to schedule the work when the pool is not in use.

Salt water is the exception to read about early: salt water environments, including salt water pool decks, are harsh on sealers.[3] If you have a salt system, ask about the sealer before choosing the finish.

What replacement involves

Replacement means breaking out the old slab, correcting the base and slope, and pouring new concrete with new control and expansion joints. Contractors, not homeowners, handle this. Digging for a new base can trigger a legal duty to call before you dig: no person shall make or begin any excavation or demolition without first submitting a locate request to the notification center.[6] Your contractor should arrange that.

Permits depend on your locality and the scope. Prince William County lists concrete (patio) slabs on grade that are not designed to support a future building addition among the work that does not need a building permit.[5] Barrier or drainage changes are another matter, so ask your building department before you commit.

Quantities, in a nutshell

If you are comparing bids on a resurfacing job, one 40 lb bag covers approximately 16 square feet at a thickness of 1/4 inch,[1] which tells you how fast material adds up on a big deck. For the money side, see how much it costs to redo a concrete pool deck in Virginia.

Stop and call a pro if

  • The deck has moved. Sinking, tilting or heaved slabs, or a gap between the deck and the pool, call for a contractor's assessment of the base, not a coating.
  • Water runs toward the pool. Fixing slope usually means replacing, and it affects the pool as well as the deck.
  • You see cracks wider than a pencil line, or raised edges. Start with how to fix cracks in a concrete pool deck to see what is safe to seal yourself.
  • The job involves removing the slab, digging or new drainage. Those are contractor work, with 811 and possibly permits.
  • You cannot tell which problem you have. Get a written assessment before deciding.

Getting help in Virginia

It is advisable to get at least three written bids or estimates using identical plans and specifications so you can compare prices and contractors.[4] Ask each bidder to price both resurfacing and replacement, so you can see the gap. If the work you are considering is valued at $1,000 or more, a valid Virginia Contractor's License is required for the license category in which the contractor is to work.[4]

Common questions

How thick is a resurfacing layer?
Thin. Quikrete's Re-Cap resurfacer is applied from a feather edge of 1/16 inch up to 1/2 inch. That is enough to renew a worn or scaled surface, but it does not add structure or fix a slab that is moving.
Will resurfacing hide the cracks in my pool deck?
It hides hairline cracks for a while, but the manufacturer says old cracks can reappear due to movement in the base concrete, and that reflective cracking cannot be completely prevented. Cracks need to be repaired and cured before the resurfacer goes on.
Can I resurface a sealed or painted deck?
Not directly. The Re-Cap data sheet says to apply it only to bare concrete, not to painted or sealed surfaces, so a coating has to come off first. Ask any contractor how they will prepare a coated deck.
Do I need a permit to replace a pool deck in Virginia?
It depends on the locality and on what is being built. Prince William County, for example, lists concrete patio slabs on grade that do not support a future building addition among the work that does not need a building permit. Pool, barrier or drainage changes can be treated differently, so call your building department before the work starts.
Does a salt water pool change the answer?
It can shorten the life of any sealer on the deck. Euclid's data sheet says salt water pool decks are harsh on sealers. Ask a contractor which surface and sealer they recommend for a salt water pool.
