Is Your St. Louis Concrete Showing Signs of Sealer Failure?
"Unsealed concrete in St. Louis absorbs everything: motor oil, road salt, rainwater, and freeze-thaw cycles that crack it from the inside out."
Water Absorption Test Fails
Pour a cup of water on your concrete. If it soaks in within 30 seconds instead of beading, the sealer is gone. Unprotected concrete is one bad winter away from scaling damage.
Freeze-Thaw Surface Scaling
Missouri's freeze-thaw cycles push water into pores, freeze, expand, and pop the surface layer. This is largely preventable with a properly applied penetrating or topical sealer.
Oil & Stain Absorption
Unsealed concrete is porous. One oil drip soaks in permanently within hours. A vehicle drip pad on unsealed concrete becomes a permanent feature without professional treatment.
Stamped Color Fading
Decorative and stamped concrete depends on surface sealer to maintain color vibrancy. Faded stamped patterns mean the sealer has failed and the exposed pigment is bleaching under UV.

Years Sealing St. Louis Concrete
Why Does Proper Concrete Sealing in St. Louis Require More Than a Roller and a Bucket?
Sealer Matched to Your Application
Penetrating silane-siloxane sealers for freeze protection. Acrylic topical sealers for decorative surfaces. Polyurethane for high-traffic commercial areas. One sealer doesn't fit all — and the wrong choice fails early.
Cure Time Verification
New concrete must cure 28 days before sealing. Sealing too early traps moisture vapor and causes white haze (efflorescence) and bond failure. BTS always verifies cure time — we won't seal concrete that isn't ready.
Joint Caulking Included
Expansion joint failure is the primary entry point for freeze-thaw water damage. BTS includes polyurethane caulking on all expansion joints with every sealing job — at no extra charge.

How It Works
How Does the BTS Concrete Sealing Process Work?
Five consistent steps from surface prep to full cure — every job, every time.
1
Cure Verification
We confirm concrete age and cure status before scheduling. New concrete requires 28 days minimum. Previously sealed concrete is assessed for adhesion compatibility.
2
Surface Preparation
Surface is thoroughly cleaned (pressure washed or chemically cleaned) and completely dried. Failed or peeling sealer is stripped with chemical stripper or grinder.
3
Joint Caulking
All expansion joints are routed, cleaned, and filled with flexible polyurethane sealant color-matched to your concrete. This step prevents freeze-thaw water entry.
4
Sealer Application
Two thin coats applied by sprayer or roller. First coat opens pores; second coat provides surface film. We monitor drying conditions between coats.
5
Cure & QA
Surface is cordoned off. Dry to foot traffic: 4–8 hours. Vehicle traffic: 24–48 hours. Full cure: 72 hours. We confirm the cure timeline with you before leaving.

Common Questions
What Questions Do Homeowners Ask About Concrete Sealing in St. Louis?
In St. Louis, concrete should be resealed every 3–5 years for penetrating sealers and every 2–4 years for topical film sealers, depending on traffic and exposure. Missouri's freeze-thaw cycles and road salt exposure accelerate wear — don't wait until you see surface spalling. BTS can assess your current surface condition at no charge.
Topical wet-look sealers add a gloss film that enhances the concrete's color and repels surface stains. Matte or natural-look sealers (typically penetrating silane-siloxane types) provide water and salt protection without changing the surface appearance. Gloss levels range from satin to high-gloss — we'll show you samples before we apply.
No. New concrete needs to cure fully — typically 28 days — before sealing. Sealing too early traps moisture vapor that causes white haziness (efflorescence) and bond failure. BTS always verifies cure time before scheduling a sealing job.
Most sealers are dry to foot traffic within 4–8 hours in dry conditions. Vehicle traffic should wait 24–48 hours. Full cure is 72 hours. Avoid water, dew, and rain for the first 24 hours after application — we check the weather forecast before scheduling.
Yes — expansion joint caulking is included with every concrete sealing job. Failed caulk at joints is the primary entry point for water that causes freeze-thaw cracking and edge spalling. We use flexible polyurethane sealant color-matched to your concrete.
Penetrating sealers (silane-siloxane) soak into the concrete and chemically react with pore structure to block water and salt without changing surface appearance. Topical sealers form a protective film on top, adding gloss or sheen while resisting stains. For St. Louis driveways, we recommend penetrating sealers for freeze-thaw protection; topical for decorative and stamped surfaces.
Usually yes, but the concrete must be completely dry first — typically 24–48 hours in sunny weather. BTS often schedules cleaning on day one and sealing on day two to ensure proper drying. We won't apply sealer to damp concrete. The timeline is confirmed during your free estimate.
