An amazing range of sealants, adhesives, cements and putties designed to seal gaps, seal cracks, seal holes and bond with various building materials The result of all these options is that it is often difficult to find the most suitable sealant for your building materials. But, within the sea of caulking tubes that line store shelves is a line of super products known as resilient sealants. Once fully cured, they are pliable and resilient to accommodate any expansion and contraction, a phenomenon known as dynamic joint movement, these sealants can be used indoors or out and will adhere to almost any building material, including wood, steel, stone, tile, brick, glass, plastic, vinyl, Most importantly, flexible sealants are highly resistant to seasonal movement and long-term exposure to the elements, which are the two main reasons most sealers fail. Fill a gap between two different materials, such as vinyl siding and wood trim, which tend to expand and contract at different rates based on temperature and humidity. When you seal a joint that must remain closed, you need an elastomeric sealant.
