Sealing and Caring for Stamped Concrete in Ontario
Updated October 2026
In Southern Ontario, plan on resealing stamped concrete every two to three years, closer to two on a driveway or any surface that takes heavy road salt. The sealer is what holds the colour and keeps water and salt out of the surface. Between coats, use sand for grip instead of de-icing salt in the first winter and keep the sealer up to date.
Stamped concrete keeps its colour and its crisp pattern the way a deck keeps its stain: with a little regular care. The care is not hard. This page covers how often to seal, what the sealer is doing, and a simple routine. For the bigger picture on patterns, colour and cost, see our complete guide to stamped concrete.
How often to reseal
Plan on resealing every two to three years. Stamped concrete is sealed when it is poured, so the clock starts at the pour. A driveway, or anything that takes heavy road salt over the winter, sits on the shorter end of that window.
Do not wait for the surface to look bad. Put the date of the last coat on your calendar, and book the next reseal before the two to three years are up.
What the sealer is doing
Southern Ontario runs concrete through many freeze-thaw cycles every winter, each time the temperature crosses zero. Water gets into the surface, freezes, expands, and pries the top layer apart. Road salt makes it worse by pulling more water in and driving more cycles.
The sealer is the barrier that keeps water and salt out of the surface. It also gives the colour its depth. Stamped concrete leans on its sealer more than a plain slab does, because the colour and the sharp pattern edges sit right at the surface, where the damage happens. When the sealer wears thin under sun, salt and snow shovels, the colour fades and the surface starts drinking water.
A simple routine
Before winter. Reseal if the surface is due, so the sealer is on before the salt arrives.
Winter. For grip, use sand. Go easy on de-icing salt, and avoid it completely in the first winter after a new pour.
The first winter is the most careful one
New decorative concrete is still gaining strength through its first winter, and salt is hardest on it then. For a new slab, use sand for grip the whole first season, and use salt sparingly from then on.
Slip resistance when you reseal
Sealed stamped concrete can be slippery when wet. We mix an anti-slip additive into every coat we apply. If you reseal it yourself, or hire someone else, ask for the same. A deep stone texture already holds more grip than a slick, high-gloss finish, and an additive in the sealer brings the traction up on any surface that gets wet, like a pool deck or a shaded walkway.
If you would rather not maintain it
Resealing is a real, recurring task, not a one-time cost at the pour. If that sounds like more than you want to take on, say so when we quote. Exposed aggregate gives you texture and stone character with less upkeep, and we would rather pour the right surface than the fancier one.
Get a resealing schedule in writing
When we quote stamped and decorative concrete, the first coat of sealer is part of the job, and we give you a written resealing schedule so you know what is coming. Ask for a free written quote for a new patio or driveway border and we will go through the finish and the upkeep before you sign anything.
How often should stamped concrete be sealed?
Every two to three years for most surfaces in Southern Ontario. A driveway or any surface that gets heavy road salt sits on the shorter end of that window. The first coat goes on at the pour, so the first reseal is due two to three years after the job, not every year.
What happens if I skip resealing?
The sealer wears under sun, salt and snow shovels. Once it is gone the colour fades, the finish dulls, and the surface starts soaking up water, which freeze-thaw cycles then work on every winter. The surface wears years before it should.
Can I use de-icing salt on stamped concrete?
Go easy on it. New decorative concrete is still gaining strength through its first winter, and salt is hardest on it then, so use sand for grip that first season. After that, use salt sparingly and keep the sealer up to date, because the sealer is the barrier between the salt and the surface.
Will sealing make stamped concrete slippery?
A glossy, smooth sealer can be slippery when wet. We mix an anti-slip additive into every coat we apply, and you should ask for the same from whoever reseals it later. This matters most around pools and on shaded walkways that stay damp.
