Part 1 – Information & Preparation

General Information

Perdüre UMC is a three-component urethane modified cementitious flooring system designed to protect concrete substrates from chemical corrosion, abrasion, impact and thermal shock. Cementitious polyurethane flooring systems are suitable for food processing areas, production areas, bottling plants, commercial kitchens, pharmaceutical plants, sanitize/wash areas and chemical processing areas.

The application of sealer is not required with Perdüre UMC-SL, unless specified for cleaning or aesthetic purposes or for additional chemical resistance. A prime coat of Perdüre UMC-CO is recommended with Perdüre UMC-SL to reduce the potential for outgassing craters/holes. The wearing surface for Perdüre UMC-SL is smooth and easily cleaned under most process conditions. No priming is required for Perdüre UMC-TG, a pigmented sealer is required.

Surface Preparation

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Technical Bulletin-1. Specific attention should be paid to the following:

1. Concrete Placement—an efficient vapor barrier  should be directly under slabs on or below grade to prevent moisture migration
2. Curing and Finishing techniques of the concrete substrate
3. Age of concrete
4. Previous contamination of the substrate
5. Present condition of the substrate
6. Make sure the floor is free of moisture vapor transmission

Also, the temperature conditions of the area to receive the flooring system should be checked. An optimum room temperature of 75°F with a slab temperature of 50°F is required for proper cure of the resin flooring system.

Special Conditions

Do not apply in temperatures below 45°F, above 85°F, or if relative humidity is above 85%. To extend working time in hot temperatures, consider cooling the Part I and Part II resin components in ice water or cold storage. Do not apply to sand-cement screeds (tile setting bed mortars), asphaltic substrates, glazed tile or brick (unless glaze is mechanically abraded), copper, aluminum, softwood, or existing coatings of epoxy, polyester, or urethane. DO not apply to wet concrete or to polymer modified concrete with moisture content above 10%. Do not apply to concrete if air temperature is within 50°F of dew point. DO not featheredge application or mix material by hand.

Material Quantities

One unit of Perdüre UMC-SL contains
Part I - 1 gallon
Part II – 1 gallon and
Part III – 44 lbs
Coverage – 20 ft² at 1/4", 30 ft² at 3/16", 40 ft² at 1/8" thickness

One unit of Perdüre UMC-CO contains
Part I – 1/2gallon
Part II – 1/2gallon
Part III – 7lb (Filler Powder)
Coverage – 100ft² per unit at 12mil thickness
Note: The Part III (filler powder) is packaged in 50 lb bag and must be weighed out in 7lb portions at the jobsite or measured out by volume…7lbs of filler powder is approximately 1gallon by volume.
