Concrete sealing for slabs that live outside.
Penetrating sealers, densifiers, and topical finishes matched to the slab and its abuse. South Florida concrete fights water, salt air, and UV every day of the year, and bare concrete loses that fight slowly, then suddenly.

Three sealers, three different jobs.
“Sealing” is not one product. Matching the chemistry to the slab is the entire service.
Silane and siloxane repellents
Soak into the slab and make it shed water and salt without changing how it looks. The right answer for driveways, pool decks, and anything that needs grip to stay exactly as it is.
Lithium silicate hardeners
React with the concrete itself to harden the wear surface and choke off dusting. The standard treatment for bare warehouse slabs and the chemistry under every polish we install.
Acrylic and urethane films
A protective film with a look, satin to wet-look gloss, color-enhancing on pavers and stamped work. Sacrificial by design: it takes the abuse and gets renewed on a cycle.
The longer answer on concrete sealing.
Concrete is a sponge with a compressive strength rating. Left bare in South Florida it drinks rain, irrigation overspray, salt air, pool chemistry, and whatever drips out of the car, and every one of those leaves something behind: efflorescence, rebar corrosion, spalling, stains that never come out. Concrete sealing is the cheap insurance against all of it, and it is dramatically cheaper than the repair work we get called for when it was skipped for a decade.
The walkthrough decides the chemistry. A driveway that needs to keep its texture gets a penetrating silane/siloxane that disappears into the slab. A warehouse floor that dusts gets a lithium densifier. Stamped concrete and pavers that should look rich and wet get a topical acrylic. Interior floors heading toward a finished look move into polish territory, and slabs with coatings failing on top need grinding first, sealer over a failing coating just seals in the failure.
Application is fast: most residential jobs are done in a day, walk-on in 2 to 24 hours depending on product, and reseal cycles run 3 to 10 years by chemistry and traffic. We log what went down and when, so the reseal is a phone call, not an investigation. Recent sealed work is in the gallery; send a photo and square footage and you will have a real quote in 24 hours.
Common concrete sealing projects.
The four jobs that fill the sealing calendar in South Florida.
Driveways and walkways
Penetrating repellent keeps rain, irrigation rust, and tire grime from soaking in, with zero change to traction. The five-year-old driveway that still looks new is the one that got sealed in year one.
Pool decks and patios
Salt and chlorine eat unsealed concrete from the surface down. Penetrating sealers shut that off while keeping the deck barefoot-safe; color-enhancing topicals are available where the look matters more than grip.
Warehouse dust-proofing
Bare slabs shed fine cement dust forever, onto inventory, into machines, through HVAC. A lithium densifier hardens the surface and stops the dusting for the life of the floor.
Stamped and decorative resealing
Stamped patios and paver drives lose their color when the original sealer wears off. A clean-and-reseal brings the depth back in a day, on a 2-to-4-year cycle that protects the investment underneath.
What a concrete sealing job looks like.
Walkthrough
Free, on-site. Slab condition, prior sealers, exposure, the right chemistry. Same-week.
Surface prep
Pressure wash or grind as needed, stain treatment, moisture check. Sealer only bonds to clean concrete.
Application
Sprayed or rolled to the coverage rate on the data sheet, two coats where the product calls for it.
Cure + handoff
Walk-on in 2 to 24 hours by product. Reseal cycle documented so future maintenance is a phone call.
What people ask us most.
How long does concrete sealer last?
By chemistry: penetrating silane/siloxane repellents run 7 to 10 years, densifiers are effectively permanent, topical acrylics are sacrificial at 2 to 4 years outdoors. We log the product and date at handoff so the reseal lands on schedule instead of after the damage.
Penetrating or topical, which one do I need?
Keep the look and the grip: penetrating. Want wet-look color and shine on stamped or decorative work: topical. Stop a warehouse slab from dusting: densifier. The walkthrough matches the chemistry to the slab, and the wrong pick is the main reason DIY sealing disappoints.
Will sealer make my patio or pool deck slippery?
Penetrating sealers, no, they leave the texture untouched, which is why they are our default around water. Gloss topicals can get slick when wet, so where we use them we broadcast a traction additive into the final coat.
Can you seal brand-new concrete?
After it cures. Most penetrating sealers want 28 days; some densifiers can go earlier. Sealing too soon traps moisture and clouds the finish, so on new pours we schedule the sealer visit, not rush it.
My old sealer is flaking white. Can you fix it?
Yes, that is a failed topical letting go. We strip or grind the failed film off, then reseal with the right product for the exposure. Sealing over flaking sealer just laminates the problem.
Does sealing stop oil and rust stains?
It stops them from becoming permanent. Sealed concrete gives you hours instead of minutes to wipe up oil, and irrigation rust sits on the surface instead of soaking in. Existing stains get treated during prep, most lift substantially, some old ones leave shadows we will point out honestly at the walkthrough.
