SB-190High Strength Adhesive Caulk
Berger recommends Surebond Everseal (SB-190)* when using adhesive to install the CL Snow Guard. This product has been proven in the industry for this particular use. SB-190 requires 28 days (672 consecutive hours) of 50 degrees Fahrenheit, or warmer temperatures to fully cure to 2000-psi shear tensile strength.
If these conditions cannot be met, Surebond Everflex (SB-1800)**, a cold weather sealant that sets in 24 hours and fully cures in 48 to 72 hours in temperatures as low as (-20F) to 500psi shear tensile strength, should be considered for sealing mechanical fastened snow guards when temperature does not permit use of SB-190 adhesive.
Berger recommends SB-190 as the strongest adhesive. In any case, of adhesive bond failure, there is no warranty by Berger for the adhesive. SB-1800** SB-190*
