Concrete & Masonry / Protective Sealers

Concrete & Masonry Sealers

Penetrating and film-forming sealers for concrete, pavers, and masonry — VOC-compliant formulas matched to your state's regulations. Free shipping.

A concrete sealer protects concrete, pavers, and masonry from water, salt, stains, and freeze-thaw damage, extending the life of driveways, patios, and slabs. Because sealer VOC limits are set by state and local regulation, the selection available to you depends on where you're located — choose your state below to view the compliant sealers we can ship to your address.

Select Your State to View Available Sealers

Sealer availability is governed by state and local VOC (volatile organic compound) regulations, so the products we can ship differ by location. Select your state to see the compliant sealers available to you.

What a Concrete Sealer Does

Concrete is porous, so untreated slabs absorb water, salt, oil, and other stains — which leads to surface scaling, freeze-thaw damage, efflorescence, and a worn, dingy look over time. A sealer closes off or coats that pore structure so liquids bead and roll off instead of soaking in, protecting the surface and making it far easier to clean. The right sealer extends the life of driveways, patios, walkways, pavers, and foundation walls, and can restore or enhance color on decorative surfaces.

The most important choice is the type of sealer, because it determines how the product protects the surface, how it looks, and how long it lasts.

Penetrating vs. Film-Forming Sealers

Every concrete sealer works one of two ways, and the difference drives everything else:

Penetrating sealers — silane, siloxane, and silicate/densifier chemistries soak into the concrete and react below the surface. They repel water and salt while leaving a natural, matte look and letting the slab breathe. Best for driveways, exterior flatwork, and freeze-thaw or de-icing exposure.
Film-forming sealers — acrylics, and (for interiors) epoxies and urethanes, leave a protective layer on top. They add sheen — from satin to high gloss — and can enrich color, which makes them the choice for decorative concrete and pavers.

Rule of thumb: reach for a penetrating sealer when you want invisible, breathable protection outdoors, and a film-forming sealer when you want sheen, color enhancement, or a wearing surface.

Common Sealer Types

Type	How It Works	Best For
Silane / Siloxane	Penetrates and chemically repels water & salt; natural look	Driveways, exterior slabs, freeze-thaw & de-icing areas
Silicate Densifier	Reacts with concrete to harden and densify the surface	Polished floors, dust-proofing, abrasion resistance
Acrylic	Forms a thin film; adds sheen and color enhancement	Decorative concrete, pavers, stamped & colored surfaces
Epoxy / Urethane	Builds a durable, chemical-resistant surface film	Interior floors — garages, shops, commercial slabs

Why Sealer Availability Depends on Your State

Sealers contain volatile organic compounds (VOCs), and the legal VOC limit for architectural coatings is set by state and regional air-quality regulation — so a solvent-based sealer that's legal in one state may be restricted in another. That's why our sealer selection changes by location: when you choose your state above, you'll see only the formulas that are compliant and shippable to your address, including low-VOC and water-based options where required.

If you don't see a specific sealer for your state, it's because it can't be legally sold there — the compliant equivalent will be shown in your state's selection instead.

How to Apply Concrete Sealer

01Clean & Dry

Remove dirt, oil, and old coatings, and let the surface dry fully. New concrete should cure per the sealer's instructions (often ~28 days) before sealing.

02Apply Thin & Even

Roll or spray thin, uniform coats — penetrating sealers soak in; film-formers need even coverage to avoid streaks and puddles.

03Cure & Recoat

Respect the dry/cure and recoat times on the label, and keep traffic off until fully cured. Reapply periodically per the product's service life.

Always follow the specific product's data sheet for coverage rate, coats, dry time, and surface prep — these vary by chemistry and manufacturer.

Concrete Sealer FAQ

Why does the sealer selection change by state?

Sealers contain VOCs, and the maximum legal VOC content for coatings is regulated at the state and regional level. A sealer that's compliant in one state may be restricted in another, so we show only the formulas that are legal and shippable to your location. Select your state above to see your available options.

What's the difference between a penetrating and a film-forming sealer?

Penetrating sealers (silane, siloxane, silicate densifiers) soak into the concrete and protect from within, leaving a natural, breathable, matte finish — ideal outdoors and in freeze-thaw areas. Film-forming sealers (acrylics, epoxies, urethanes) leave a protective layer on top that adds sheen and can enhance color, which suits decorative concrete, pavers, and interior floors.

What sealer should I use on a driveway?

For most exterior driveways, a penetrating silane/siloxane sealer is the go-to — it repels water and de-icing salt, resists freeze-thaw damage, and keeps a natural look without making the surface slippery. If you want sheen or color enhancement on a decorative driveway, an acrylic film-forming sealer is an option, keeping slip resistance in mind.

How long does concrete sealer take to dry?

It depends on the chemistry and conditions, but many sealers are dry to the touch within a few hours and accept foot traffic in 24 hours and vehicle traffic in 48–72 hours. Always follow the specific product's data sheet, since temperature and humidity change the cure time.

Can I use the same sealer on pavers?

Pavers are commonly sealed with acrylic (film-forming) sealers that enhance color and can lock joint sand, or with penetrating sealers for a natural look. Choose based on whether you want sheen and color enhancement or invisible protection, and confirm the product is rated for pavers and for your climate.

How often should concrete be resealed?

As a general guide, penetrating sealers can last several years to a decade, while film-forming sealers often need reapplication every 1–3 years depending on traffic and exposure. Watch for water no longer beading or a worn, dull finish as the signal to reseal, and follow the product's stated service life.
