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, 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 our non-yellowing DECRA-SEAL™ product. Avoid brush or roller contact with wood partitions. The surface may become slippery under certain conditions.

HEALTH HAZARDS
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 runoff water. Refer to product Material Safety Data Sheet for complete health and safety information.
