MasonryDefender Brick Sealer Satin Sheen
MasonryDefender Brick Sealer Satin Sheen provides interior and exterior protection for brick walls. It forms a water-resistant barrier that helps prevent moisture-related issues like cracking and flaking, contributing to long-lasting durability. The finish is a clear satin sheen that enhances the natural color of masonry without changing its appearance. It creates an easy-to-clean surface that repels dirt and grime, simplifying maintenance for both indoor and outdoor brick walls.
Best for: Homeowners sealing exposed brick onExterior facades or interior accent walls who want a subtle shine and easier cleaning. It’s especially suitable where moisture resistance is a priority without altering the brick’s natural look.
Limitations: As a water-based sealer, it benefits from proper surface preparation and ventilation. Multiple coats can increase shine but should be applied consistently for uniform appearance.
MasonrySaver All-Purpose Heavy Duty
MasonrySaver All-Purpose Heavy Duty Water Repellent is designed to seal and protect untreated concrete, brick, and stone surfaces. It is suited for exterior or interior use and provides long-lasting protection with a claimed seven-year warranty for vertical surfaces. The product also offers de-icing salt protection, guarding concrete against winter damage. It’s a solid option for larger outdoor areas, driveways, and foundation walls that face freeze-thaw cycles and salt exposure.
Best for: Projects that require robust moisture and salt resistance on concrete and masonry surfaces, including foundations, driveways, and walls exposed to winter conditions.
Limitations: As a general-purpose water repellent, it’s important to verify compatibility with all substrate types in your project and ensure even coverage to avoid uneven appearance.
AMES Blue Max White Liquid Rubber
Ames Blue Max White is a strong, highly adhesive elastomeric liquid rubber waterproofing solution. It provides up to 900% elongation, allowing the membrane to expand and contract with the substrate to resist cracking and peeling. This makes it particularly suitable for basements, below-grade foundations, and other areas where movement or settlement occurs. It can be applied by brush, roll, or spray on vertical or horizontal surfaces, forming a flexible protective layer.
Best for: Projects needing a highly elastic, crack-bridging waterproofing membrane, especially in foundations, basements, or areas prone to minor movement.
Limitations: Its elastomeric nature means the finish is flexible and may require careful surface preparation to ensure adhesion on challenging substrates. Avoid use on surfaces where a hard, rigid film is preferred.”
Siloxa-Tek 8500 Ready to Use
Siloxa-Tek 8500 Ready to Use is a penetrating silane/siloxane sealer designed to reduce water and moisture intrusion. It preserves the natural aesthetics of concrete, brick, masonry, and pavers by remaining breathable and non-film forming, so it will not peel or flake. It is DOT approved and resists damage from chlorides and deicing salts. The formula is designed to offer long-lasting protection with six times higher actives than typical water-based sealers, and it resists wind-driven rain by penetrating deeply into the surface.
Best for: Surfaces where long-term, breathable protection is desired without altering color or texture, including concrete driveways, brick veneer, and paver paths in salt-prone or freeze-thaw environments.
Limitations: Penetrating sealers rely on proper surface porosity; excessively sealed or non-porous surfaces may show limited performance. Reapplication intervals depend on environmental exposure.
Drylok Clear Latex Masonry Sealer
Drylok Clear Latex Masonry Sealer provides a clear protective layer for masonry surfaces. As a latex-based waterproofer, it seals against moisture while maintaining the natural look of the masonry. This option is straightforward to apply and provides a transparent coating that does not alter surface color, making it suitable for preserving the appearance of older brick or stone walls while adding a moisture barrier.
Best for: Quick, surface-level moisture protection where preserving the color and texture of the masonry is important, such as decorative brick exteriors or interior stone features.
Limitations: Latex sealers may require reapplication sooner in severe weather zones or high-traffic outdoor areas compared to more heavy-duty silicone or siloxane-based sealers.
Buying Guide
What surface needs protection?
Choose a product based on substrate type (brick, concrete, stone, or wood) and whether you need interior or exterior protection. Penetrating sealers like Siloxa-Tek 8500 work well when you want to preserve natural appearance, while elastomeric coatings like Blue Max White provide a flexible, waterproof membrane for surfaces prone to movement.
Do you need breathability or a film-forming layer?
Breathable sealers prevent moisture buildup inside the material and reduce the risk of peeling. If you want a non-film, natural look, pick a breathable penetrating sealer. If you require a protective film that blocks moisture on high-exposure surfaces, consider elastomeric or acrylic film sealers.
Weather and climate considerations
Areas with frequent freeze-thaw cycles or salt exposure benefit from products that resist deicing salts and provide long-term water repellency. For basements or below-grade walls, an elastomeric or high-elasticity membrane can bridge cracks and movement.
Application and maintenance
Review surface prep instructions, reapplication intervals, and ventilation needs. Some sealers require multiple coats for optimal performance, while others are ready-to-use with minimal prep. Proper cleaning before application improves adhesion and uniform appearance.
Durability versus appearance
Consider whether you prioritize maintaining the natural color and texture or achieving a more uniform sheen and enhanced color. Satin finishes add slight shine, while clear sealers maintain the native look of masonry.
Common questions
- Is a penetrating sealer better than a film-forming coating? Penetrating sealers preserve appearance and allow moisture movement, while film-forming coatings can offer a stronger barrier on aggressive surfaces.
- Can these products be used on all masonry surfaces? Compatibility varies by product; always check substrate compatibility and test a small area first.
- Will these sealers prevent cracking? Sealers reduce moisture that can contribute to cracking but do not repair existing cracks; separate crack repair may be needed.
- How long do sealers typically last? Durability depends on climate, surface exposure, and product type; refer to manufacturer guidelines for reapplication intervals.
- Do these products affect color or texture? Some sealers are clear and preserve appearance; others may add a satin or glossy finish.

Frequently asked questions
- What is the difference between penetrating sealers and elastomeric coatings? Penetrating sealers seep into the material to repel water without forming a thick film, while elastomeric coatings create a flexible outer layer that blocks moisture and bridges small cracks.
- Are sealers safe for indoor use? Many are safe when used as directed, but ensure proper ventilation and follow product guidelines for indoor applications.
- Can sealing prevent mold and mildew? Sealing reduces moisture ingress, which can help deter mold growth, but it is not a substitute for ventilation and humidity control.
- Do I need to remove old coatings before applying a new sealer? In many cases, you should remove, repair, or lightly profile the surface to improve adhesion; follow the product’s surface prep instructions.
- How often should I re-seal masonry surfaces? Re-sealing intervals vary by product and environment; consult the manufacturer’s guidelines and assess surface condition over time.
