WR Meadows EXPO-GLOSS OTC Clear 5 Gallon Pail
WR Meadows EXPO-GLOSS OTC is a transparent, high-solids, film-forming curing, sealing, and dustproofing compound intended only for exposed aggregate concrete. It gives a glossy wet-look finish that shows the natural stone and raises resistance to staining and wear, while the permeable film lets moisture in the cured substrate evaporate. It complies with the National EPA architectural coatings standard, LADCO, and Phase I OTC VOC regulations. This is the transparent formulation. EXPO-GLOSS OTC is flammable and is for exterior use only. This 5 gallon pail covers about 1,500 to 3,000 sq ft.

Frequently Asked Questions
What surfaces is WR Meadows EXPO-GLOSS OTC intended for?
Exterior exposed aggregate concrete only, freshly finished or old. Do not use it on standard concrete, polymer-modified surfaces, aggregate or concrete overlays, toppings, mortars, resin systems, or terrazzo, and not on very porous brick or dense stone.
How much area does the EXPO-GLOSS OTC 5 Gallon Pail cover?
300 to 600 sq ft per gallon, or about 1,500 to 3,000 sq ft for this 5 gallon pail. Coverage varies with finish and conditions, so apply a test area first.
How is EXPO-GLOSS OTC applied?
On fresh work, apply once aggregate exposure is complete, surface moisture is gone, and cement paste residue is removed. Existing surfaces must be clean and free of stains, oil, and curing compounds; they may be damp but not puddled. Mix gently, then spread a thin, even coat with a good natural bristle brush or short-nap roller, avoiding puddles. Apply it without diluting or thinning.
What precautions apply to EXPO-GLOSS OTC?
EXPO-GLOSS OTC is flammable, and empty containers may hold flammable vapors. Keep it away from flames, sparks, and ignition sources, use adequate ventilation, and block HVAC ducts. Apply when surface and air temperatures are between 40 and 90 F, not on hot aggregate in direct sun or on substrates with excessive moisture, and do not over-apply. The surface will be slippery while drying and may be slippery once dry; SURE-STEP can be added for slip resistance.
