BOSS® 850 Colors Silicone for Surfaces must always be applied to sound, clean, dry, frostfree surfaces.
Tooling is recommended and if possible, should be completed in one continuous stroke.
Tool joints within 10 minutes of application. Remove masking tape before a surface skin
has formed.
Cleaning the joint surface on both new and old jobs
Bonding surfaces on both new and remedial jobs must be clean, dry and free of dirt, dust
and soap film.
Use masking tape where bead lines of exact shapes are required
Use masking tape before applying sealant and remove immediately after a bead is
completed and before a skin forms (7 to 15 minutes).
Applying the sealant
BOSS® 850 Colors Silicone for Surfaces can be applied directly from the caulking cartridge
with either an air-operated or hand-operated cartridge gun. Do not break the cartridge seal
until just before using.
After applying the sealant and after a skin has formed, do not disturb the joint for 48 hours.
A previously opened cartridge may be reused by removing the cured plug of sealant from
the tip.
