Concrete Sealing Questions

A penetrating silane sealer typically lasts 5-10 years. A film-forming acrylic needs reapplication every 2-3 years, depending on traffic. The installer will specify the expected lifespan of the product used in your written estimate.

Unsealed concrete absorbs oil, water, and road salts. Over time, freeze-thaw cycles and chemical penetration cause spalling, cracking, and deep staining. Repairs at that stage cost significantly more than sealing would have.

Stains are treated and cracks are filled during surface prep before any sealer is applied. Sealing over untreated cracks traps moisture and lifts the coat, so prep is never skipped.

Cure time depends on the sealer product and ambient temperature. Most film-forming sealers allow foot traffic within 24 hours and vehicle traffic within 48-72 hours. Your written estimate will state the specific cure window.

Concrete sealing on existing residential or commercial slabs does not require a permit in Fort Worth. If the project involves structural repairs or drainage changes, the installer will flag any requirements during the on-site assessment.

A penetrating silane sealer soaks into the pores and leaves no surface film, ideal for driveways and areas where slip resistance matters. A film-forming acrylic sits on top and adds sheen, better suited to decorative patios and interior floors.
