🛡️ CONCRETE SEALING
Concrete Sealing in Florissant, CO
Sealing concrete in Florissant isn't maintenance for its own sake — it's the most cost-effective thing a Teller County property owner can do to extend the service life of a driveway, patio, or floor slab. At 8,000 feet with aggressive freeze-thaw cycling, intense ultraviolet exposure, and the magnesium chloride residue from county road treatment, unsealed concrete ages fast. Concrete Doctor has been sealing and protecting Colorado concrete since 1994, and we match the sealer type to the specific exposure conditions each Florissant surface faces.

Concrete Sealing for Florissant, CO Properties
The environment around Florissant is demanding on concrete in ways that aren't immediately obvious to property owners. High-altitude UV breaks down concrete binder chemistry and degrades surface sealers more quickly than at lower elevations — a sealer rated for five-year reapplication at sea level may need attention in three years here. Meanwhile, winter brings dozens of freeze-thaw transitions, each one driving moisture deeper into unsealed concrete until the surface begins to scale and spall from the inside out.
Teller County road maintenance relies heavily on magnesium chloride for ice control on U.S. 24 and local county roads. This compound is highly effective at melting ice but equally effective at attacking concrete chemistry when it migrates onto driveways and aprons during snowmelt runoff. Penetrating sealers that block this chloride migration are particularly important for Florissant properties near any treated road surface — and nearly every Florissant property is close enough to be affected during a melt event.
Our Concrete Sealing Approach
Concrete Doctor applies both penetrating sealers and surface film-forming sealers depending on what the concrete surface requires. Penetrating sealers — silane, siloxane, or silane-siloxane blends — work by chemically bonding within the pore structure of the concrete, creating a hydrophobic barrier that repels water and chloride ions while allowing vapor to escape. These are ideal for driveways, exterior patios, and any surface where a natural concrete appearance is desired without a sheen.
Film-forming sealers, including acrylic and polyurethane-based products, create a surface coating that provides additional UV and abrasion protection while enhancing the concrete's appearance. We use these on stamped concrete, polished surfaces, and decorative flatwork where the surface finish needs to be maintained. In both cases, surface preparation before sealing — cleaning, degreasing, and in some cases light mechanical preparation — determines whether the sealer bonds properly and achieves its intended service life.
The Right Time to Seal Florissant Concrete
The best time to seal concrete is before visible damage appears — not after the surface has begun to scale or spall. On new concrete, sealing should happen after the initial cure period (typically 28 days for full curing) and before the surface has been exposed to a full winter season. On existing concrete in good condition, resealing on a two-to-four-year cycle maintains protection against moisture infiltration and chloride migration without allowing the surface to degrade between applications.
For existing concrete that already shows light scaling or surface wear, sealing is still valuable but works best in combination with surface cleaning and any needed crack repair first. We assess the current condition of each surface before recommending a sealing approach — not every slab needs the same preparation or the same product.
Stamped and Decorative Concrete Sealing at Altitude
Florissant properties with stamped concrete driveways, colored flatwork, or decorative patio surfaces have an additional reason to prioritize sealing: surface finish preservation. The UV intensity at altitude fades and grays stamped concrete color rapidly without a UV-inhibiting film sealer refreshed on schedule. What looked rich and detailed when first installed can look washed out within three or four years without maintenance sealing.
We use sealer products with UV stabilizer packages specifically for decorative concrete applications — not standard clear acrylic construction sealers, which lack the UV resistance needed for Florissant's solar exposure. Application technique also matters: consistent film thickness, proper ambient temperature, and dry surface conditions all affect how the sealer cures and how long it lasts. These are variables we control on every application.
Serving Florissant, CO Since 1994
From Lakewood, we make the trip to Florissant and throughout Teller County because we understand that mountain concrete has different protection needs than city slabs. Sealing on a schedule — before you can see the surface degradation — is the approach that saves property owners the most money over time. To schedule a free on-site evaluation of your driveways, patios, or floor slabs, call us at (303) 988-2558. We'll identify what's exposed, what's at risk, and what sealing program makes sense for your property.
Frequently Asked Questions
In Teller County's mountain environment, most driveways benefit from resealing every two to three years for penetrating sealers and every two to four years for film-forming sealers, depending on traffic and sun exposure. The higher altitude accelerates both UV degradation of the sealer and freeze-thaw stress on the surface beneath it. An annual visual check — water should still bead on a properly sealed surface — is a simple way to track when resealing is needed.
Yes, but we address the cracks first. Sealing over an open crack doesn't prevent water from infiltrating through it — the crack needs to be filled with an appropriate material before sealing. We include crack assessment and filling as part of the sealing preparation process.
Different surfaces often call for different sealer types. Exterior driveways typically get a penetrating sealer for moisture and chloride resistance. Interior garage floors, if not getting a full coating system, often benefit from a harder film-forming sealer or densifier that reduces surface dusting and provides some stain resistance. We evaluate each surface separately and recommend accordingly.
Penetrating sealers leave no visible surface film and don't change the appearance of the concrete — the surface looks the same but repels water. Film-forming sealers create a low to medium gloss sheen and may slightly deepen the color of the concrete. We discuss appearance preferences before product selection.
