Concrete Sealing in Tamarac, FL

Why exterior concrete needs protection

Outdoor concrete here deals with constant moisture, intense sun, heavy rain and frequent irrigation. Bare concrete absorbs water like a sponge, which feeds black mildew and green algae, especially in shaded areas near hedges and along the north side of the house. Sprinkler systems fed by well or canal water leave orange rust stains. Oil drips from cars, leaf tannins and pool chemicals add more discoloration. A sealer slows or stops water from soaking in, so the surface stays cleaner, dries faster and is easier to wash.

Types of sealers

Penetrating sealers

Silane and siloxane sealers soak into the concrete and repel water from within. They do not change the appearance or make the surface slippery. They are our usual choice for driveways, walkways and pool decks where footing matters.

Film-forming sealers

Acrylic and urethane sealers form a thin layer on top. They can enhance color and add a wet look or a satin sheen. They are well suited to decorative concrete, pavers and stamped patios, though they need recoating every few years and can get slick if applied heavily.

Cleaning before sealing

Sealer locks in whatever is on the surface, so cleaning is essential. We pressure wash with surface cleaners, treat mildew and algae with appropriate cleaners, and address rust stains with a concrete-safe rust remover. Oil spots are degreased. The concrete then needs to dry fully, which can take a day or more in humid weather.

Pool decks

Pool decks see chlorinated or salt water splash, sunscreen, bare feet and furniture. We use penetrating sealers that keep the surface breathable and slip resistant. Painted or coated decks that are peeling can be stripped and resurfaced; see our driveway coating page for resurfacing options that also work around pools.

Driveways

Driveways benefit from sealing because oil, tire marks and rust wash off more easily. A penetrating sealer will not change the look, while a tinted or film-forming option can refresh faded concrete. We seal expansion joints and repair minor cracks first.

Screened patios and entryways

Covered areas still get wet from blown rain and humidity, and mildew thrives in shade. Sealing these surfaces makes routine cleaning much easier. For screened patios that need more than a sealer, our flake floor systems add color and texture.

Timing and weather

Sealers need dry concrete and a few hours without rain. During the wet season, we schedule for mornings after a dry stretch and watch the radar closely. The dry season, roughly late fall through spring, makes scheduling easier. We will reschedule rather than seal damp concrete, because trapped moisture ruins the result.

How often to reseal

Penetrating sealers typically last several years. Film-forming sealers need recoating more often, especially in full sun. We leave care notes with the expected schedule for your surfaces.

Questions

Will sealing make my driveway slippery?

Penetrating sealers do not change traction. Film-forming sealers can, so we add grit where needed.

Can you seal pavers?

Yes, with sealers that stabilize joint sand and enhance color.

Does sealing stop all mildew?

It slows growth considerably. Shaded areas still benefit from an occasional rinse.

Sealing around landscaping and screen enclosures

Before we spray anything, we cover plant beds, screen frames, doors and stucco walls so sealer lands only on concrete. Overspray on glass or aluminum is wiped right away. Pets and kids should stay off the surface for a few hours while it dries, and we leave the sprinklers turned off until the next day so water does not spot the fresh sealer.
