While ‘caulk’ and ‘sealant’ are terms that are used interchangeably in exterior building restoration, sealants are usually more highly engineered and have peak performance when compared to caulks. Usually, caulks are used simply to fill a gap, with very little function required besides that. Sealants on the other hand are made to withstand movement and exposure to the elements over a long period of time. Some sealants have been manufactured with various additional characteristics such as fire stopping sealants which can withstand exposure to fire. There are also made to have structural capabilities, especially for use in commercial settings. Think of sealants as the older, stronger brother of caulks.

Sealers, or water repellents, repel water by minimizing absorption of the same. Sealers are not made with the intention of waterproofing walls. If you require this, you need to do it properly through sealants, proper flashings and proper maintenance. Sealers more or less play a short term role and should ideally be replaced with a more permanent solution if water/moisture is found to be a long-drawn challenge.
