Buyer's Guide: Masonry Sealer for Exterior

Benefits of Using Masonry Sealer Exterior:

• Protection from Moisture: One of the primary advantages of using a masonry sealer for the exterior is its ability to provide a protective barrier against moisture. This is particularly important for masonry surfaces, such as brick or concrete, as they are prone to damage from water penetration.
• Prevention of Stains: Masonry surfaces are often exposed to various elements, including dirt, pollutants, and organic matter. A masonry sealer can help prevent these substances from penetrating the surface, thereby minimizing the risk of stains and discoloration.
• Enhanced Durability: By creating a protective layer on the exterior surface, masonry sealers can increase the durability of the material. They can help combat the effects of weathering, freeze-thaw cycles, and harmful UV rays, which can ultimately extend the lifespan of your masonry.
• Improved Aesthetic Appeal: Applying a masonry sealer can enhance the color, vibrancy, and overall appearance of your masonry surface. It provides a glossy or natural-looking finish, depending on the sealer type, to enhance the aesthetic charm of your exterior.
• Easy Maintenance: With a masonry sealer, maintenance becomes hassle-free as it simplifies the cleaning process. The sealed surface can be easily washed with mild soap and water, reducing the need for harsh chemicals or abrasive cleaning methods.

Types of Masonry Sealers:

1. Penetrating Sealers: These sealers penetrate deep into the masonry substrate, forming a chemical bond that helps repel water and other substances. They are suitable for both above-grade and below-grade applications and allow the masonry to retain its natural appearance without altering its texture.
2. Film-Forming Sealers: These sealers create a protective film on the surface of the masonry. They can enhance the aesthetics of your exterior by offering a glossy finish and are more resistant to staining and abrasion. However, they may alter the texture and color of masonry.
3. Acrylic Sealers: Acrylic sealers are a type of film-forming sealer that provides excellent protection against moisture, UV rays, and staining. They are known for their durability and versatility, as they can be applied to a wide range of masonry surfaces.
4. Silane/Siloxane Sealers: These penetrating sealers are specifically designed to protect against water damage. They work by forming a water repellent barrier while still allowing the masonry to breathe. Silane/siloxane sealers are often used in high-moisture environments.

Factors to Consider When Choosing a Masonry Sealer:

• Surface Compatibility: Ensure the sealer is suitable for the specific type of masonry surface you want to seal. Check the manufacturer's recommendations to ensure compatibility.
• Application Method: Consider the application method required for the sealer. Some sealers can be sprayed, rolled, or brushed on the surface. Choose a method that suits your comfort and the size of the project.
• Drying Time: Check the drying time specified by the manufacturer. This will give you an idea of how long the surface will be out of use while the sealer cures.
• Maintenance Requirements: Evaluate the maintenance requirements of the sealer. Some sealers may require periodic reapplication or additional coats to maintain their effectiveness.
• Environmental Impact: Consider the environmental impact of the sealer. Look for low VOC (volatile organic compound) or eco-friendly options if sustainability is a priority for you.
