Butyl tape and liquid sealants are two of the most common sealing materials for in-plant or offsite building construction. While both are used to create a waterproof seal, the technologies differ in their composition, application methods, and effectiveness in different scenarios.
Liquid or fluid-applied sealants are viscous materials and applied with a caulking gun, dispensing wand, spray gun or rollers. They can be comprised of various chemistries, including silicones and polyurethane, depending on the application substrate and anticipated joint movement. Liquid sealants, including Tremco’s TREMPRO 635+, are often used for filling gaps and cracks in walls and ceilings, as well as for sealing joints and seams in roofs, windows, and doors. They are also used to coat surfaces in order to protect against moisture, chemicals, and other environmental factors.
Butyl tape is easy to apply and requires no special tools or equipment, making it a popular choice when a project requires a quick turnaround. It can be applied quickly to almost any substrate and provides a strong, long-lasting seal with no waiting for it to cure. However, butyl tape may not be the best choice for large areas or complex geometries, as it can be difficult to apply evenly and may not adhere well to uneven surfaces.
Each job has a unique set of requirements that may make one of the sealants more ideal than the other. Thankfully, both tape and fluid-applied sealants can effectively create a waterproof substrate for your project.
