| Sealer / surface | Typical lifespan* | What shortens it |
|---|---|---|
| Penetrating sealer on concrete | ~3–5 years | Salt, heavy traffic, no cleaning |
| Film-forming "wet-look" on concrete | ~2–3 years | UV, traffic paths, freeze-thaw |
| Sealed pavers (joint-stabilizing) | ~3–5 years | Shade/algae, joint wash-out |
| Natural stone (penetrating) | ~3–5 years | Moisture, harsh cleaners |
"How long will it last?" is the first thing most Columbus homeowners ask before sealing a patio — and the honest answer is a range, not a number. The lifespan depends on the sealer you use, the surface it's on, and how hard our central-Ohio climate works on it. Below are realistic figures, what eats into them, and the simple test that tells you when it's time to reseal.

Penetrating vs. film-forming: the big lifespan divider
The sealer type matters more than any brand claim. Penetrating sealers soak into the surface and protect from within, so there's no surface film to wear off — they commonly last around 3–5 years. Film-forming (acrylic "wet-look") sealers sit on top and give that rich, wet sheen, but the film takes the abrasion of foot traffic and UV, so it usually needs refreshing around every 2–3 years. Which one suits your patio is worth reading up on — see penetrating vs. film-forming sealers for the full comparison.
Why Ohio is hard on sealer
Central Ohio stacks three stressors: freeze-thaw that drives water in and out of the surface all winter, de-icing salt that's chemically aggressive, and summer UV on open patios. Add shade-loving algae on the north side of the house, and the same sealer that would last five years in a mild climate lands at the lower end of its range here. That's why our numbers skew toward the conservative side — plan for the low end, not the marketing high end.
The water test: your reseal alarm
You don't have to guess. Sprinkle some water on the patio: if it beads up, the sealer is still doing its job; if it soaks in and darkens the surface, the protection is spent and it's time to reseal. Do this each spring — combined with a look for returning stains, a faded patchy appearance, or a worn finish in the walking paths, it's a reliable read on where you are in the cycle.

Resealing on time is the cheap path
The reason the schedule matters is money. A patio kept sealed is a routine clean-and-seal — or for pavers, a re-sand and seal. A patio left until water is soaking in, joints have washed out, and stains have set usually needs a full restoration before it can be sealed at all, which costs far more than the reseal you skipped. The sealer's job is to buy years; the reseal is what keeps buying them.
Bottom line for Columbus patios
Expect roughly 3–5 years from a penetrating sealer and 2–3 years from a wet-look film in our climate, plan for the low end, and let the water test — not the calendar alone — make the final call. Sealing on schedule is what keeps a patio in routine-maintenance territory instead of restoration territory.
