Caulking is used to provide caulk sealing for construction, renovations, and repairs. This process finds its origins among the Native Americans in medieval times.

They used pitch and amber as a malleable sealant that helped secure cracks and defects. This process inspired European explorers to bring a similar solution into the mainstream.

In the 19th century, this was made possible by John Dicks. He initially produced large-scale caulk for industries but eventually ventured into small containers for homeowners in the 1950s.

From there, it was picked up by several commercial companies, eventually growing into the caulk we are familiar with today.
