A washable surface layer simplifies maintenance and cleaning for outdoor walls and indoor brick features alike.
1 Gallon Bricks & Exterior Surfaces, All Purpose Concrete Sealer
OAIEGSD’s sealer is engineered for all-weather performance on outdoor surfaces, including driveways, pavers, brick, and concrete. It resists rain, snow, and freeze-thaw cycles while forming a penetrating, water-repellent barrier. The zero-VOC formula helps prevent water penetration and protects against cracking, spalling, and moisture-related damage. Beyond protection, it enriches the natural color of concrete and bricks, preserving a polished outdoor appearance without altering surface texture.
MasonryDefender Chimney Brick Sealer
This clear, water-based siloxane sealer is designed for exterior vertical masonry surfaces, including chimneys. It bonds with masonry while remaining breathable to allow trapped moisture to escape, preventing freeze-thaw damage. It does not alter surface color, offering reliable exterior protection for brick walls and other vertical surfaces while preserving the natural look of the masonry.
Rainguard Water Sealers Brick Sealer
Rainguard’s brick sealer creates an invisible, filmless barrier that protects brick and mortar from wind-driven rain and moisture. The hydrophobic, penetrating formula guards against cracks, efflorescence, and staining while maintaining a natural finish. This makes it suitable for indoor and outdoor brick surfaces, chimneys, walls, and walkways where a non-gloss appearance is preferred.
McKinnon Concrete Sealer (5 Gallon)
McKinnon Concrete Sealer is a professional, industrial-grade option designed for outdoor and indoor use. It is a penetrating, water-based acrylic sealer that aims to prevent peeling or cracking and works across substrates such as concrete, bricks, pavers, stone, and stucco. Its versatility makes it suitable for large brick projects, including patios, driveways, and pool decks, where long-term durability is essential.
Buying Guide: Key Purchase Considerations
- Penetration vs. film-forming: Penetrating sealers preserve a natural appearance and maintain breathability, while film-forming sealers add a surface layer and may alter gloss. Choose based on whether you want a natural look or enhanced surface shine.
- Finish preference: Finishes range from clear, natural, satin, to slight gloss. For brick exteriors, a satin or natural finish often balances aesthetics with dirt resistance.
- Breathability: Especially for masonry like chimneys or old brick walls, breathable formulas prevent moisture entrapment that can cause freeze-thaw damage and efflorescence.
- Water repellency and durability: Look for low- or zero-VOC formulas, deep penetration, and resistance to wind-driven rain, salt, and oil stains—critical for driveways and patios exposed to the elements.
- Application surface: Confirm compatibility with brick, concrete, pavers, stone, or combinations. Some products are multi-surface; others target specific substrates.
- Maintenance and longevity: Consider reapplication intervals and how the sealer cleans—whether it forms a washable layer or requires stripping prior to re-sealing.
- Environmental considerations: Zero-VOC and low-odor options reduce indoor air impact and are often preferred for projects with nearby living spaces or vegetation.
- Coverage expectations: Check the product’s coverage rate per gallon to plan for total project area and know whether a second coat is recommended for added protection or sheen.
- Color and appearance: If color enhancement is desired, select a product designed to deepen or preserve natural brick color without masking original texture.

When selecting a brick sealer, align product features with your climate, brick type, and desired maintenance level. For long-term durability in freezing environments, prioritize breathable siloxane-based formulas that prevent moisture entrapment. For high-traffic areas like driveways, a penetrating sealer that resists staining and allows washing without altering color can keep surfaces looking clean and uniform over time.
