Review TENON Waterborne Sealer Salt Barrier Protects Concrete And Masonry From

The **Tenon 100% Acrylic Waterborne Sealer (Product #129840)** is a high-performance, salt-resistant concrete masonry unit (CMU) sealer designed to enhance the durability and longevity of brick, block, and stone surfaces while providing superior protection against moisture, efflorescence, and environmental contaminants. Formulated with a **100% waterborne acrylic resin**, this clear, non-yellowing sealer penetrates deep into the porous substrate, creating a durable, breathable barrier that resists water absorption while allowing moisture vapor to escape naturally. Ideal for both new construction and restoration projects, this product is specifically engineered to combat the damaging effects of **salt crystallization and efflorescence**, which can weaken masonry over time by depositing mineral salts on surfaces. The sealer s advanced formulation bonds chemically to the concrete, forming a resilient film that prevents water infiltration while maintaining the natural appearance of the masonry, ensuring that the texture and color remain intact without the risk of discoloration or streaking. Whether applied to exterior walls, retaining walls, or decorative stonework, this sealer provides long-lasting protection against freeze-thaw cycles, UV exposure, and chemical spills, making it an excellent choice for both residential and commercial applications. Its easy application with a brush, roller, or sprayer, along with a quick drying time, ensures efficient installation without lengthy downtime. Backed by Tenon s reputation for quality and performance, this waterborne sealer delivers a balance of durability, clarity, and environmental responsibility, making it a trusted solution for preserving the integrity and aesthetic appeal of concrete masonry for years to come.

**Pros and Cons of buying a Tenon 129840 Waterborne Sealer (Salt Barrier for Concrete Masonry)**

### **Pros**

1. **Effective Salt Barrier Protection** This sealer is specifically designed to prevent salt intrusion, which is critical for concrete masonry units (CMUs) exposed to deicing salts, coastal environments, or freeze-thaw cycles. It helps prevent efflorescence, spalling, and long-term deterioration.

2. **Waterborne Formula** Unlike solvent-based sealers, this waterborne option is lower in volatile organic compounds (VOCs), making it more environmentally friendly and safer to apply in occupied spaces without strong fumes.

3. **Penetrating Sealer** It penetrates the concrete rather than forming a surface film, allowing the material to breathe while still providing protection. This helps maintain structural integrity while extending the lifespan of the masonry.

4. **Versatile Application** Suitable for new and existing concrete masonry units, including block walls, pavers, and stucco substrates. It can be applied to both interior and exterior surfaces, though exterior use is more common.

5. **Easy Application** Can be applied with a brush, roller, or spray equipment, making it accessible for both professional contractors and DIYers. It typically requires minimal surface preparation (clean, dry, and slightly rough surfaces work best).

6. **Long-Lasting Performance** When applied correctly, it provides durable protection for several years, reducing the need for frequent reapplication compared to some other sealers.

7. **Resistance to UV Damage** Unlike some surface-sealing products that yellow or degrade under sunlight, this penetrating sealer maintains its clarity and effectiveness over time.

8. **Compatibility with Other Treatments** Can often be used in conjunction with other protective coatings or waterproofing systems, depending on the project s requirements.

### **Cons**

1. **Limited to Salt Barrier Functionality** While excellent for salt protection, it may not offer additional benefits like stain resistance, color enhancement, or enhanced slip resistance. If these features are needed, a different product may be required.

2. **Requires Proper Surface Preparation** Like most penetrating sealers, it performs best on clean, dry, and slightly porous surfaces. Neglecting preparation (e.g., not removing dirt, oil, or efflorescence) can reduce effectiveness.

3. **Application Sensitivity** Overapplication can lead to pooling or uneven coverage, which may affect adhesion or performance. Underapplication may leave areas vulnerable to salt damage. Proper technique is essential.

4. **Drying Time** The sealer may require several hours to dry, depending on humidity and temperature. This can slow down construction or renovation timelines.

5. **Cost Compared to Basic Sealers** While not excessively expensive, it may be pricier than generic concrete sealers without specialized features. The cost depends on the project size and application method.

6. **Not a Waterproofing Solution** This sealer protects against salt intrusion but does not make the masonry waterproof. For areas prone to heavy rain or flooding, additional waterproofing measures (e.g., dampproofing or membrane systems) may still be necessary.

7. **Limited Color Enhancement** Unlike some aesthetic sealers, this product does not enhance or darken the color of the concrete. If visual appeal is a priority, a different sealer may be needed.

8. **Potential for Efflorescence if Not Applied Correctly** If the concrete is not fully cured or if the sealer is applied too soon after installation, efflorescence (white mineral deposits) can still occur. Proper timing and curing are critical.

### **Conclusion**

The **Tenon 129840 Waterborne Sealer** is an excellent choice for protecting concrete masonry units from salt damage, particularly in harsh climates or environments where deicing salts are used. Its waterborne formula, penetrating nature, and durability make it a practical option for both new construction and maintenance projects. However, it is not a one-size-fits-all solution it excels at salt barrier protection but lacks features like waterproofing or color enhancement. For projects where these additional benefits are needed, complementary products may be required.

### **Recommendation**

- Your primary concern is protecting concrete masonry from salt damage (e.g., in cold climates, near coastlines, or where deicing salts are used).

- You prefer a low-VOC, environmentally friendly option.

- You want a penetrating sealer that allows the masonry to breathe while extending its lifespan.

- You need waterproofing in addition to salt protection.

- You want enhanced stain resistance or color enhancement.

- Your project requires a surface-sealing film for slip resistance or aesthetic purposes.

For most applications where salt resistance is the top priority, this sealer is a reliable and effective choice. Always follow the manufacturer s instructions for surface preparation and application to ensure optimal performance.
