Understanding Sealer Coatings
There are several different ways to seal the sandblasted
surface on glass. On the majority of sandblasted glass produced by Milestone
Mfg., a proprietary polymer coating (part no. 7325) is applied directly
after the sandblasting process. This sealer coating is recommended for
all interior glass applications installed in a dry environment. For exterior
installations, or moisture prone environments, Milestone Mfg. Recommends
the application of our renewable water repellent exterior sealer coating
(part no.XXXX). Both of these products are environmentally friendly and
have been approved for application.
Milestone Mfg.'s interior sealer has a smooth, uniform,
soft satin appearance that is almost undetectable, enhancing the sandblast
finish. This sealer coating aids in the resistance of contamination to
the sandblasted surface and makes the surface easier to clean than raw
sandblasted glass. Though this sealer coating aids in protecting the sandblasted
surface, it too can be susceptible to damage by abrasion, staining, or
chemical degradation. Proper cleaning practices are imperative and must
continually be disseminated throughout all maintenance personnel. Re-sandblasting
and re-seal coating the glass is the only way to repair damage to the
Milestone Mfg.'s renewable water repellent sealer has a
slightly different look than the interior sealer. This sealer also aids
in the resistance of contamination to the sandblasted surface and makes
the surface easier to clean. The sealed surface virtually repels anything
from sticking to it. Buffing with a clean dry cloth can often clean the
sealed surface. Unlike the interior sealer, this sealer can be reapplied
bringing the sandblasted surface back to a pristine condition. This sealer
is not recommended on butt-glazed applications, as the tape used in this
glazing technique will not stick to the sealed surface. It is possible
to apply this sealer to the glass after glazing. Milestone Mfg. will share
its knowledge of the appropriate application techniques if desired. Milestone,
however, cannot be held liable for the appearance of the sandblasted glass
when seal coated by others.
Both types of sealer coatings require specific drying times.
These drying times can fluctuate with temperature and humidity. The interior
sealer is always allowed to dry for a minimum of twelve hours before handling.
The renewable sealer can dry within two hours.
