DAP Alex Plus Acrylic Latex Caulk Plus Silicone

DAP Alex Plus is a highly recognized acrylic latex sealant reinforced with silicone, designed for both interior and exterior applications such as windows and doors. The DAP brand has a long history dating back to 1865, originally starting as a wax and sealing producer. It has since evolved into a leader in the home improvement and construction supply industry, known for its extensive range of caulks, sealants, and adhesives.

Today, DAP is a key subsidiary of RPM International Inc., a global leader in specialty coatings and sealants. Most DAP products are manufactured in the United States at facilities in Maryland, Ohio, and Texas, though some production occurs in neighboring countries to support international distribution. The brand remains a staple in hardware stores across North America due to its reliable formulation and ease of use for DIYers and professionals alike.
