APPLICATION
SURFACE PREPARATION
The key to long-term sealant and adhesive performance is proper
substrate preparation. The substrate must be clean, dry, frost free,
sound and free of any oils, greases, or incompatible sealers, paints or
coatings that may interfere with adhesion and good joint performance.
Porous surfaces should be cleaned of dust & debris from fabrication
or job site dirt before cleaning using a stiff brush or using oil &
moisture free compressed air. Mechanical methods, such as wire
brushes, grinders, etc. may be required to remove surface
contamination, debris and failed sealants such as in re-caulking
applications.
JOINT DESIGN
A thin bead of sealant will accommodate more movement than a thick
bead. Working joint depths should never exceed ½" (12 mm) or be
thinner than 1/8" (3 mm), ideally ¼" (6 mm). The ratio of joint width to
depth should be 2 to 1. Joints should be designed or cut to work well
within the movement capability of the sealant allowing for erection
and installation tolerances, time of year of installation and sealant
movement capability. QUIKRETE
