Review Sashco Sealant Products for Exterior Wall Preparation

What happens here

The video opens with a professional painter introducing a promotional box of Sashco sealant products. He demonstrates each product, explaining its general purpose and benefits. Although the video does not show the actual application of elastomeric paint or specific waterproofing techniques for exterior walls, it features products vital for surface preparation. These include: 1. **Exact Color Sealant (0:12.380-0:18.720):** This is a tintable caulking that can be mixed with any paint to achieve a perfect color match. In the context of exterior wall waterproofing, this product would be ideal for sealing small cracks, joints, and gaps (e.g., around trim, windows, or doors) on exterior surfaces before the final application of elastomeric paint. Its tintable nature ensures a seamless finish with the chosen paint color, contributing to both aesthetics and a comprehensive moisture barrier. 2. **Clean and Seal (0:20.480-0:27.760):** Described as a product for bathrooms and kitchens that cleans soap scum and mildew. This product is not directly applicable to exterior wall waterproofing. 3. **Morflex Mortar and Stucco Repair (0:27.760-0:38.239):** This product is specifically designed for repairing cracks in mortar and stucco. This is extremely relevant for exterior wall waterproofing, as elastomeric paint requires a sound, stable substrate. Cracks in stucco or mortar must be properly repaired and sealed to prevent water intrusion. Using a flexible repair material like Morflex helps maintain the integrity of the wall, preventing future cracking and ensuring the elastomeric paint adheres effectively and provides a continuous waterproof layer. 4. **Through the Roof (0:38.239-0:44.879):** This sealant is highlighted for patching and repairing roofs, even in wet conditions. While excellent for roof waterproofing, its primary use is not for vertical exterior walls, although it demonstrates Sashco's robust waterproofing capabilities. 5. **Lexel (0:44.879-0:52.800):** Described as an all-around amazing clear sealant that is cleanable with water. While versatile, its primary benefit of being clear might not be fully utilized on surfaces that will be painted over. However, its strong adhesive and sealing properties make it a viable option for clear sealing applications on exterior walls where specific movement is not anticipated, or as a general high-performance sealant. 6. **Big Stretch (0:52.800-1:04.720):** This product is emphasized for its flexibility, used on baseboards both inside and outside. For exterior wall waterproofing, Big Stretch is a critical product. It's designed to accommodate significant movement, making it perfect for sealing dynamic joints, gaps between different materials, or areas prone to structural movement on exterior walls. Using Big Stretch prevents the elastomeric paint layer from cracking over these moving joints, thus maintaining the integrity of the waterproof barrier.
