Paver Sealer: How to Choose and Apply the Right One
Sealing pavers is one of those jobs that looks simple from the driveway and gets complicated the moment you start reading labels. Water-based or solvent-based. Penetrating or film-forming. Natural, satin, or wet look. Two coats or one. And underneath all of it, the question most people actually want answered: do my pavers even need sealing, or is this something I can skip?
This guide walks through the decision the way you would actually make it. What a paver sealer does and does not do, the three choices that decide which one you need, how to match a sealer to the surface you have, and then the application itself, step by step, including the mistakes that turn a good product into a blotchy weekend.
Should you seal pavers at all?
A paver sealer is not paint and it is not a repair. It is a protective layer that gets into the top of a porous surface and closes it off, so the things that normally soak in have a harder time doing it.
That is worth doing for most people, but it is worth being honest about what you get.
| Sealing helps with | Sealing will not fix |
|---|---|
| Water soaking deep into the stone | Pavers that have sunk, lifted, or shifted |
| Oil, grease, and food stains sitting on the surface | Cracks, chips, or broken units |
| Mold, mildew, and organic growth taking hold | A base that was not compacted properly |
| Dirt grinding into an open, porous surface | Stains already locked into the stone |
| Colour looking faded and chalky | Joint sand that was never installed |
The most important line in that table is the last one on the right. A sealer locks in whatever is on the surface when you apply it. If the pavers are stained, sealing them does not clean them up; it preserves the stain under a protective layer. Clean first, always, and if there is a stain you cannot lift, decide whether you can live with it before you seal over it.
The other honest caveat is that sealing is not permanent. Sun, traffic, freeze and thaw, and cleaning all wear a sealer down, and eventually you reseal. How long that takes depends on how much sun and traffic the surface gets, which is why nobody can give you a number that actually applies to your patio. There is a simple test further down that tells you when the time has come.
The three choices that decide which paver sealer you need
Almost every product on the shelf is some combination of three decisions. Get these right and the rest is application technique.
1. What it is made of: water-based or solvent-based
Solvent-based sealers carry their resin in a chemical solvent that flashes off as the sealer dries. They have been around a long time and they bite hard into dense surfaces, but they bring strong fumes, they are not friendly to plants and pets while they are wet, and the runoff is not something you want in a garden bed.
Water-based sealers carry the same job on water instead. They are lower odour, far easier to clean up, and much kinder to the area around the work. For a home patio, driveway, or pool deck, where you are working next to lawn, planting beds, and whoever is using the yard, a water-based sealer is usually the more sensible choice.
Superclear SuperSeal is water-based. It is a cross-linking acrylic formula, it is Zero VOC, and once it has dried it is safe around plants and pets. That combination is the reason it exists: no harsh solvents, no nasty runoff into the beds along the edge of the patio.
2. What it does to the surface: penetrating or film-forming
A penetrating sealer soaks into the top of the stone and works from inside it. A film-forming sealer lays a layer on top. In practice most good sealers do some of both, and the ratio is set less by the product than by how you apply it.
This is the part people get wrong. A sealer applied thick and neat tends to sit on top as a film. The same sealer thinned with water penetrates further, because the water carries the resin down into the surface before it flashes off. A seal that has gripped inside the stone has far more to hold onto than one sitting on the face of it.
That is exactly why Superclear's own directions for SuperSeal call for two thinned coats rather than one heavy one: a 50/50 mix of sealer and water, twice, with drying time in between. You can apply an undiluted single coat, and it will look good and it will protect the surface. The two-step method is what maximises how far into the substrate the sealer gets, and that is what the longevity of the job rests on.
3. The finish you want: natural, satin, or wet look
This is the choice you will actually look at every day.
| Finish | What it looks like | Typical use |
|---|---|---|
| Natural / matte | Colour barely changes; the stone looks untreated | Natural stone where you want the raw look preserved |
| Satin | A soft, low sheen; colour a little deeper | Travertine, natural stone, quieter patios |
| Wet look / gloss | Colour noticeably richer and darker, with a visible shine, as though the surface has just been rained on | Concrete pavers and driveways, feature patios, pool surrounds |
"Wet look" is the term the whole industry uses for the last one, and it describes it well: a wet-look sealer gives permanently the deep, saturated colour that pavers only show for ten minutes after a shower.
With SuperSeal, the finish you land on depends mostly on the surface you put it over. Following Superclear's step-by-step directions, the same 50/50 mix produces a gloss finish on concrete and pavers and a natural satin finish on travertine and other natural stone. The product page also describes applying it straight for a wet gloss and cutting it with about thirty percent water for satin. If you have a specific finish in mind and you want to be certain before you open the first jug, call the Superclear technical line on 888-849-0588 and ask for the mix that gets you there on your particular surface.
Matching the sealer to the surface you have
Superclear's directions split the job by surface, and the split is worth understanding because it changes both your tool and your result.
Concrete pavers, brick pavers, and poured concrete. Use a sprayer, ideally with a fan tip for even coverage. These surfaces take the sealer readily and, with SuperSeal's two-coat method, finish glossy.
Travertine and natural stone. Use a roller and lay down a thin, even coat rather than spraying. Natural stone finishes to a natural satin rather than a gloss, which is usually what people want on travertine in the first place.
Concrete block, stucco, and manufactured stone. These are porous and thirsty, and vertical surfaces need a light hand so the sealer does not run. Expect to use more material than you would on the same area of dense poured concrete.
How much material a given area takes varies enormously with how porous it is. New, dense pavers drink far less than old weathered ones, and a rough block wall drinks more than a smooth slab. Superclear publishes coverage figures for each of these surfaces in the directions on the SuperSeal product page; check those against your measured square footage, or call 888-849-0588 and talk it through before you order.
One thing worth clearing up: Superclear also makes a product called WB Primer and Sealer, and the names are close enough to cause mix-ups. That one is a water-activated primer and sealer for preparing a substrate before an epoxy pour, used with the Countertop Epoxy system and sold in white, grey, and black. It is not a paver sealer. For pavers, concrete, stone, and stucco, SuperSeal is the product.
How to apply paver sealer, step by step
This is the two-coat method from Superclear's own directions. The tools are simple: a pressure washer or a hose and a stiff deck brush, and a pump sprayer or watering can, with a fan nozzle recommended for the best coverage.
- Clear the surface. Furniture, planters, toys, anything standing on the pavers.
- Clean it properly. Pressure wash the whole surface to take off dirt, stains, mold, and mildew. No pressure washer is not a dealbreaker: wet the area down, scrub it with a stiff brush, and rinse. It is not the ideal method but it works. Whatever is left on the surface is what you are about to seal in, so this step earns more care than it usually gets.
- Let it dry completely. This is the step people skip and it is critical. A damp surface blocks the sealer from bonding correctly. Drying takes roughly three to six hours depending on the weather, and longer is better than shorter.
- Mix the first coat. Fifty percent SuperSeal, fifty percent water.
- Apply the first coat. On concrete and pavers, load a sprayer, fit a fan tip, and work in consistent overlapping passes. On travertine and natural stone, use a roller and lay a thin, even coat. Cover anything nearby you do not want coated: the product is non-toxic, but a semi-gloss sheen will land wherever the spray does.
- Deal with puddles immediately. Not every surface is flat, so some pooling is normal. Backroll the excess out with a dry roller while the surface is still wet. Puddled material that is left to dry can dry white instead of clear, and fixing that is much harder than preventing it.
- Let it penetrate. One to two hours. This is the step that carries the acrylic down into the substrate rather than leaving it on the face.
- Repeat for the second coat. Same 50/50 mix, same method, same one to two hours of drying. On concrete and pavers this second coat is what brings up the gloss; on natural stone it settles into a natural satin.
Then keep traffic off it while it dries, and keep an eye on the forecast before you start. Sealing ahead of rain is a wasted afternoon.
Five mistakes that ruin a sealing job
- Sealing over dirt. Leaves, soil, and organic growth left on the surface become weak points in the seal and cause spotted failure later. It is the single most common cause of a job that looks fine in week one and patchy in month three.
- Sealing a damp surface. Water in the pores means the sealer cannot bond where it matters. Give it the full drying time.
- Leaving puddles. They dry white and cloudy instead of clear. Backroll them out before the surface dries.
- Skipping the masking. Overspray is real. Anything you would rather not have a soft sheen on should be covered before you start spraying.
- One heavy coat instead of two thin ones. A single undiluted coat still protects the surface. Two thinned coats get further into the stone, which is where the durability of the job actually comes from.
How to tell when it is time to reseal
Forget the calendar and test the surface. Pour a cup of water onto a section that gets the most sun and traffic.
- The water beads and sits on top. The seal is still doing its job. Leave it alone.
- The water spreads and darkens the stone as it soaks in. The seal has worn through in that area and it is time to reseal.
Two other cues are worth watching for. If the colour that looked deep and rich after sealing has gone flat and chalky again, the surface is open. And if dirt and marks are suddenly harder to sweep or rinse off than they used to be, you are cleaning bare stone rather than a sealed surface.
When you do reseal, the process is the same as the first time: clean it, dry it completely, and put down two thinned coats.
Where Superclear fits

The technical line is staffed by people who make the product, and on a job where the prep matters as much as this one, five minutes on the phone before you start is worth more than an afternoon of fixing it afterwards.
Frequently asked questions
Do pavers really need to be sealed?
They do not have to be, but sealing protects a porous surface from water, oil, dirt, and organic growth, and keeps the colour from going flat. The clearest reasons to seal are a surface that stains easily, one that sits in sun and weather, or one you simply want to keep looking the way it did when it was laid.
What is the difference between a water-based and a solvent-based paver sealer?
The carrier. A solvent-based sealer uses a chemical solvent that evaporates as it dries, which means strong fumes and runoff that is not friendly to plants. A water-based sealer uses water, so it is lower odour, easier to clean up, and safer to use next to lawn and planting beds. Superclear SuperSeal is water-based.
How do I get a wet look finish on my pavers?
A wet-look finish comes from a sealer that deepens and saturates the colour of the stone and leaves a visible shine. Following Superclear's directions for SuperSeal, two coats of a 50/50 sealer and water mix finish glossy on concrete and pavers. If you want a specific finish, call 888-849-0588 and confirm the mix for your surface before you start.
How long does paver sealer take to dry?
With SuperSeal, allow one to two hours between the first and second coats. Before any sealer goes down at all, the cleaned surface needs to dry completely, which takes roughly three to six hours depending on the weather.
Can I apply paver sealer with a roller instead of a sprayer?
Yes, and on travertine and natural stone a roller is what Superclear's directions call for. On concrete and pavers a sprayer with a fan tip gives more even coverage over a large area, and a dry roller is still the tool you use to backroll any puddles out while the surface is wet.
Why did my sealer dry white in places?
Almost always puddling. Where sealer pools instead of being spread evenly, the excess can dry white and cloudy rather than clear. The fix is prevention: work in consistent overlapping passes, and backroll any puddles out with a dry roller while the surface is still wet.
How often should pavers be resealed?
Test rather than guess. Pour water on the busiest, sunniest part of the surface. If it beads and sits there, the seal is intact. If it soaks in and darkens the stone, it is time to clean, dry, and reseal.
