DAP

Over 160 Years of Innovation in Caulks, Sealants, and Adhesives

Since its founding in 1865, DAP has established itself as one of the most innovative manufacturers in the home improvement industry. What began as a small operation producing sealing wax for food canning in Dayton, Ohio, has evolved into a leading supplier of comprehensive solutions for professional contractors, remodelers, and do-it-yourself enthusiasts. Based in Baltimore, Maryland, DAP continues to build on a legacy of first-to-market innovations that have shaped how builders and homeowners approach sealing, bonding, and repair projects.

Pioneering Industry Breakthroughs

DAP's commitment to innovation is evident throughout its history. In 1964, the company pioneered the development of latex caulking compounds, fundamentally changing the caulk industry by offering a paintable, easy-to-clean alternative to oil-based products. The innovations continued through the decades: In 1980, DAP was first to market with Siliconized Latex Caulk, which was designed to cure quickly to form a strong, flexible and watertight seal that does not shrink. This pattern of industry leadership extended to specialized applications as well, including the introduction of DryDex Spackling with its patented color-change dry time indicator, and DAPtex latex insulating foam that offered a cleaner alternative to traditional polyurethane foams.

Comprehensive Product Portfolio

Today's DAP product line represents the culmination of strategic acquisitions and internal development. The company integrated respected brands like Weldwood adhesives in the 1980s, Plastic Wood in the 1990s, and Phenoseal adhesive caulk in the 2000s, each adding specialized expertise to the portfolio. Modern innovations like DAP 3.0 Advanced Hybrid Sealants and SmartBond Construction Adhesives demonstrate the company's continued focus on developing products that combine superior performance with ease of use. Whether sealing kitchen and bath areas, insulating homes against energy loss, repairing damaged surfaces, or bonding construction materials, DAP offers formulations engineered for specific applications and conditions.

Trusted Solutions for Every Project

What distinguishes DAP products is their focus on solving real-world challenges that professionals and homeowners face. The company's technical support infrastructure, including specialized product lines for demanding applications like fire-stopping sealants and commercial-grade formulations, reflects an understanding that different projects require different performance characteristics. From weather-resistant exterior sealants that withstand temperature fluctuations to interior-grade products designed for paintability and easy cleanup, DAP formulations are developed with specific use cases in mind. This specialization has made DAP products a fixture in over 60,000 retail outlets and a trusted name on job sites and in workshops across North America.
