Basic Uses

EXCEL-THANE "MCU-250" and "MCU-400" CLEAR are designed to coat decorative concrete or concrete with decorative or natural aggregates. When applied at the proper thickness, these high solids and high performance sealers will minimize dirt and oil penetration. It is easily cleaned with water and detergent and provides a high gloss, bright appearance. EXCEL-THANE "MCU-250" and "MCU-400" CLEAR are extremely wear resistant compared to conventional sealers and coatings. They are resistant to most commonly encountered dilute acids, alkalis, organic solvents and oils as well as many dry chemicals. EXCEL-THANE "MCU-250" and "MCU-400" CLEAR are used as a topcoat in Excellent Coatings Decorative Aggregate Concrete Surfacing Systems. They will brighten an exposed aggregate, highlighting the color of the aggregate. In other areas where solvent containing coatings are allowed, these coatings are clear dress up top coats for other ECI Pedestrian Traffic Waterproofing Systems.

Limitations

Limitations: Containers that have been opened must be used within one or two days, since the product is a moisture-reactive material that will gel or set up when exposed to air. Keep lid tightly sealed when material is not in use. This material contains flammable and combustible solvents. EXCEL-THANE "MCU-250" and "MCU-400" CLEAR cure faster when applied under warm temperature and high humidity conditions and slower when applied under cool temperature and low humidity conditions.

Installation

Surface Preparation: All surfaces to be coated must be clean, dry and free of all contaminants. It is recommended that concrete be cleaned by sandblasting or mechanically grinding. Metal surfaces must have no oxidation present prior to coating. Ceramic tile should be degreased and stripped to remove any wax on the surface and possibly sanded. Wood and aggregate should be cleaned with a detergent and rinsed with water under high pressure and allowed to dry. The appropriate primer or base coats should be used in all cases. Caution: Cured EXCEL-THANE "MCU-250" and "MCU-400" CLEAR may be slippery and may require the use of skid-resisting or texturing aggregate.
