Gutter Caulk

Specialty Design carries OSI-brand SBR-100 all-season exterior caulk. Our customers love how easily and consistently the caulk extrudes from the canister. OSI's formulation will maintain a strong and lasting bond that will stand the test of time and tough weather. No primer necessary. Our caulk is available in two types:
 
*OSI QUAD caulk is an advanced formula that resists dirt and dust collection, and can be applied to either wet or dry surfaces. QUAD is available in most of the 21 colors that we carry in aluminum. Please ask us about color availability.
*SBR-100 is OSI's original formula, available in white.
 
*Each cartridge is 10.2 fl oz (301 ml).
