EXPO-GLOSS® OTC
“Wet-Look” Exposed Aggregate Solvent-Based Sealer
DESCRIPTION
EXPO-GLOSS OTC exposed aggregate sealer is
a transparent, high solids, film-forming, curing,
sealing and dustproofing compound that improves
resistance to staining and wear. EXPO-GLOSS
OTC is specifically formulated to enhance the
beauty of natural stone in exposed aggregate
surfaces, while providing maximum surface
protection. When properly applied, EXPO-GLOSS
OTC produces a glossy “wet look”
finish.
USES
EXPO-GLOSS OTC is ideal for freshly finished
exposed aggregate surfaces. It is also equally
applicable for use on old exposed aggregate
surfaces.

APPLICATION
Surface Preparation...… EXPO-GLOSS OTC
may be applied over freshly finished exposed
aggregate as soon as the surface moisture has
disappeared. On existing exposed aggregate,
clean the surface thoroughly and rinse well.
EXPO-GLOSS OTC may be applied to damp
surfaces.
Mixing … For optimum performance, gentle
mixing or agitation is recommended.
CAUTION: TO AVOID FOAMING,
DO NOT MIX EXCESSIVELY.
Application Method … Apply using a good
quality natural bristle brush or a short nap roller.
Spread in a thin, even coat, being careful to avoid
puddling.
Drying … Drying times may be extended,
depending on application rate, temperature,
humidity, and project conditions. Protect the
freshly coated surface from traffic, dust,
condensation, and rain while drying. The surface
will be slippery while drying and may become
slippery under certain conditions.
Cleanup … Clean tools with an aromatic solvent
immediately after finishing application.
PRECAUTIONS
DO NOT DILUTE. FOR EXTERIOR
APPLICATION ONLY. Do not use on concrete
or on surfaces other than exposed aggregate. Do
not apply to painted or frozen surfaces. Apply a
test patch in an inconspicuous area before
applying to the intended surface.
EXPO-GLOSS OTC should not be applied on hot
surfaces in direct sunlight. These conditions
cause rapid evaporation, which does not allow the
film to form properly. Under these conditions,
the film may peel, bubble, and/or turn white
(blush).
EXPO-GLOSS OTC should not be applied to
exposed aggregate subject to excessive moisture.
Entrapped moisture in a solvent-based sealer may
cause the film to peel and/or turn white (blush).
Do not apply EXPO-GLOSS OTC over stained
wood joint dividers. This may cause stain to
spread while the sealer is wet. Continuous or
long-term exposure to ultraviolet light may cause
the film to discolor. If discoloration must be
avoided, we recommend using DECRA-SEAL™
from W. R. MEADOWS. Avoid brush or roller
contact with wood partitions. The surface may
become slippery under certain conditions.
HEALTH AND SAFETY
EXPO-GLOSS OTC IS FLAMMABLE.
Remove ignition sources prior to use. Empty
containers may contain FLAMMABLE vapors.
Handle empty containers as FLAMMABLE
liquids.
Direct contact with the product or exposure to
product vapors may cause irritation of the eyes
and/or skin. Inhalation of vapors in excess of
permissible exposure limits may result in
symptoms of transient central nervous system
depression.
In the event of a spill, contain the product, apply
absorbents and place in sealed containers. In the
event of a fire, contain all run-off water. Refer to
product Material Safety Data Sheet for complete
health and safety information.
