Review MOLD ARMOR Free Caulk And Sealant Clear 5.5 Oz. 100% Silicone

The **Mold Armor FG672 6-Mold Caulk Sealant (5.5 oz)** is a high-performance, multi-purpose silicone sealant engineered to deliver superior adhesion, flexibility, and long-lasting protection against moisture, mold, and mildew making it an indispensable choice for both professional contractors and DIY enthusiasts. Formulated with a **100% silicone base**, this sealant provides an unmatched combination of durability and waterproofing, ensuring a watertight barrier that resists cracking, peeling, or degrading even in harsh environmental conditions. Its **6-mold capability** allows for seamless application across a variety of surfaces, including wood, metal, concrete, glass, tile, and most plastics, while its **neutral cure** ensures compatibility with paints, stains, and finishes without discoloration or adhesion issues. The **flexible yet strong** consistency of the sealant accommodates structural movement, preventing leaks and gaps in areas prone to expansion and contraction, such as windows, doors, bathtubs, showers, and outdoor siding. Beyond its structural integrity, Mold Armor is infused with **mold and mildew inhibitors**, creating an inhospitable environment for microbial growth while maintaining its elasticity over time unlike traditional caulks that may degrade and become breeding grounds for moisture-related damage. With a **smooth, professional finish** and a **5.5-ounce cartridge** designed for precision application, this sealant is ideal for both small touch-ups and larger projects, offering a balance of ease of use and performance. Whether sealing gaps in a basement, reinforcing a roof flashing, or restoring a weathered deck, Mold Armor FG672 provides a reliable, low-maintenance solution that stands the test of time, ensuring long-term protection against the elements and the hidden threats of mold and moisture infiltration.

**Pros and Cons of Buying Mold Armor FG672 6-Mold Caulk Sealant (5.5 oz Silicone)**

1. **Mold and Mildew Resistance** This caulk is specifically formulated to inhibit mold and mildew growth, making it ideal for bathrooms, kitchens, basements, and other high-humidity environments where leaks or condensation are common.

2. **Flexibility and Durability** The silicone-based formula remains flexible over time, reducing the risk of cracking or peeling, which is a common issue with less resilient caulks. This ensures a long-lasting seal, especially in areas subject to movement (e.g., around pipes or windows).

3. **Waterproof and Weatherproof** It provides a watertight seal, preventing water intrusion that could lead to structural damage, rot, or further mold growth. This makes it suitable for both indoor and outdoor applications where exposure to moisture is a concern.

4. **Easy Application and Cleanup** The caulk comes in a convenient tube and applies smoothly with standard caulking tools. It can be easily trimmed and cleaned up with acetone or silicone remover, minimizing mess during installation.

5. **Non-Yellowing Formula** Unlike some cheaper silicone caulks, the FG672 retains its original color over time, avoiding the unsightly yellowing that can occur with exposure to sunlight or humidity.

6. **Versatile Use** It can be used for a wide range of applications, including sealing gaps around sinks, tubs, showers, windows, doors, and even outdoor joints where moisture resistance is critical.

7. **Adhesion to Various Surfaces** The product bonds well to glass, metal, ceramic, tile, and painted surfaces, making it a reliable choice for most sealing needs.

1. **Higher Cost** Compared to basic acrylic or latex caulks, silicone caulks like this one are more expensive. The price per ounce is significantly higher, which may be a deterrent for budget-conscious buyers or those only needing a small amount.

2. **Requires Proper Surface Preparation** Like all high-quality caulks, the FG672 performs best when applied to clean, dry, and properly prepared surfaces. Failure to clean off dirt, grease, or old caulk residue can result in poor adhesion or premature failure.

3. **Not Suitable for All Materials** While it adheres well to most common building materials, it may not bond as effectively to porous surfaces like untreated wood or certain plastics without proper priming. Additionally, it is not recommended for use on flexible substrates that can stretch excessively (e.g., some types of rubber or certain membranes).

4. **Limited Color Options** The FG672 is typically available in neutral colors (e.g., white or clear), which may not match all design aesthetics. Custom colors are not an option, unlike some acrylic caulks that can be tinted.

5. **Silicone-Specific Challenges** Silicone caulks can be more difficult to remove than acrylic caulks if a reapplication is needed. They often require specialized tools or solvents to strip, which can be inconvenient for DIYers who may need to redo a job.

6. **Potential for Overuse** Because silicone caulk is so durable and flexible, some users may overapply it, leading to excessive buildup that can look messy or interfere with proper sealing. Precision in application is key.

7. **Environmental Concerns** Silicone caulks are not biodegradable and may contain chemicals that could raise environmental or health concerns for some users, though the FG672 is generally considered low-VOC (volatile organic compound).

The Mold Armor FG672 6-Mold Caulk Sealant is a superior choice for anyone prioritizing long-term moisture resistance, flexibility, and mold prevention in critical sealing applications. Its durability and performance justify the higher cost for homeowners dealing with persistent humidity issues, leaks, or areas prone to mold. However, the increased expense and the need for careful surface preparation may make it less ideal for minor, one-time projects or those on a tight budget.

For most high-moisture areas such as bathrooms, kitchens, or basements the benefits of using a high-quality silicone caulk like this one far outweigh the drawbacks. It is particularly recommended for professionals or serious DIYers who want a reliable, long-lasting solution that minimizes the risk of water damage and mold growth.

If you are sealing gaps in areas where moisture is a significant concern (e.g., around tubs, showers, windows, or basements), the Mold Armor FG672 is an excellent investment. Ensure you prepare the surfaces properly and apply it in a controlled manner to maximize its effectiveness. For smaller, low-moisture applications where cost is a primary factor, a basic acrylic caulk might suffice, but for critical sealing needs, the FG672 is the best choice available.
