JOINT SEALANTS PREVENT WATER INTRUSION & ALLOW FOR MOVEMENT
Proper caulking of designed control joints in masonry, and at perimeters of punched out items within a masonry structure, is a critical component of any building envelope. Sky-facing head joints on masonry caps, sills, decorative elements, and water table sills commonly require a proper caulk “soft” joint to prevent excessive water intrusion.
Whether the caulking is part of a new construction project, or removal and replacement of existing caulking and backer material, FTM employs skilled caulkers, with vast product knowledge and installation experience.

CHOOSE THE CORRECT TYPE OF CAULKING SEALANT
Choosing the proper caulking type and backer material is a critical component of any caulking project. Understanding the intended function of the sealant at its installed location typically dictates the composition of the caulking that is appropriate for the joint. Based on the type of material being caulked, various types of sealant may or may not be appropriate for use. For example, some caulking can be painted once cured, while others cannot. Some materials require priming before caulking, while others may or may not stain if primed. FTM may install product samples prior to commencing a caulking project to ensure desired outcomes will be achieved, and design decisions can be made. Following a project specification when available is desired and common on commercial projects.
KEEPING WATER OUT
In some instances, caulking is counted on to keep water out of an assembly or substrate. Ideally, caulking is a watertight bridge material between waterproofing components such as flashings that are doing most of the work keeping the water out. Other uses for caulking on buildings is a bridge material between dissimilar substrates, a flexible sealant at a control joint, a flexible watertight seal around a punched out door, window, louver, or to seal a necessary penetration. Caulking can also simply serve as an aesthetic gap filler at an open abutment.
