Why Sealtite is better than
caulk?
All gunnable sealants and caulks depend on three material properties to work: adhesion, cohesion, and
impermeability to water. Sealtite is designed to address the failure of caulked
joints. Sealtite acts under compression at all times, thereby eliminating all
factors associated with tensile stresses. Sealtite has no adhesive "glue
line". Instead, it seals the joint wall interface with a high density foam
acting under constant pressure and a waterproof, hydrophobic acrylic polymer.
This composition provides for long life and resiliency allowing up to 100%
movement with zero adhesive and cohesive stresses. When Sealtite is in a 4:1
ratio it is impermeable to water.
When Should Sealtite Be
Specifed?
Sealtite should be specified
as a primary sealant when joint width exceeds 3/4" or when extreme movement is
anticipated. Sealtite B should be specified as a secondary sealant behind a
gunnable sealant in any application requiring a fail-safe sealing system. By
design, Sealtite has higher movement capabilities than most sealants and will
not shrink, which makes it a superior sealant when excessive movement is
expected. Very few gunnable sealants can match Sealtite's 100% movement
recovery making it an ideal choice for joints subject to repeated expansion and
contraction cycles. Sealtite should be specified when immediate sealing is
required as most sealants require 27 to 72 hours for a tack-free
surface.
