While most consumers might not be able to visually differentiate between one caulk or sealant and another, product formulators and chemists understand the tremendous diversity between products. After decades of innovation and development, the products used today last longer and offer advantages that far surpass their predecessors.
Caulk formulations can vary greatly based on their chemistry. To understand these differences, it is important to first look at the different chemistries used in caulks and sealants. These include silicone, polyurethane and latex-based products.
