The DAP 18275 10.1 oz 230 wh is a premium elastomeric latex sealant formulated with silicone-like toughness for both interior and exterior applications. It delivers a 100% waterproof and weatherproof seal while remaining highly flexible to accommodate joint movement caused by temperature and humidity changes without cracking. The sealant is easy to tool, paintable, and cleans up with water, making it a practical choice for HVAC, plumbing, and general construction trades. It meets ASTM Specification C920, Class 25, and is VOC compliant. The cured sealant resists mold and mildew growth, providing long-lasting performance in demanding conditions.
This sealant is suited for sealing air leaks around windows, doors, siding, trim, and baseboards in residential construction and remodel work. It is commonly used by HVAC technicians, plumbers, and general contractors to improve building envelope performance and reduce energy loss. Its low odor formula makes it appropriate for occupied spaces. The 10.1 oz cartridge is compatible with a standard caulking gun for fast, controlled application on production jobs or single-unit service calls.
Designed for use on windows, doors, siding, trim, and baseboards in residential interior and exterior applications where an elastomeric latex sealant meeting ASTM C920, Class 25 is required.
Application is performed with a standard caulking gun. Surfaces should be clean, dry, and free of dust, oil, and loose material before applying sealant. Follow applicable local building codes for air-sealing and weatherization work. Do not apply when surface or ambient temperatures are outside the range specified on the product label, and do not use as a structural adhesive or gap-filling compound beyond the joint sizes intended for this product type.
