COVERAGE:

Calculation for theoretical coverage: 77 ft²/ gal at 20 mil (1.9 m²/liter at 500 microns)

STORAGE:

Twelve months in factory delivered, unopened drums at 80 ºF (25 ºC) .Store on pallets and keep away from extreme heat, freezing, and moisture. Opened and partially used material should be used within 7 days.

MIXING:

Using a mechanical mixer, first pre-mix separately Part-A and Part-B base material thoroughly to obtain a uniform color, making sure to scrape the solids from the bottom and sides of the pail. Pour Part-B into Part-A slowly and while mixing, scrape the sides of the container. Mix the combined Part-A and Part-B mixture thoroughly in a circular motion until a homogeneous mixture and color is obtained. Use care not to allow the entrapment of air into the mixture.

SURFACE PREPARATION:

Concrete:

The surface of a concrete subfloor should be dry, smooth, structurally sound and free of depression, scale, or foreign deposits of any kind. Remove all curing compounds. Abrasive blast, sweep blast or water blast to remove all latent material and expose voids. Use a good quality epoxy filler or mortar for void and spall filling, skim coat or repairs. Prime, fill imperfections in the substrate surface to limit out-gassing. All concrete substrates, on or below grade level should be tested for moisture content. On-grade or below-grade concrete floors or slabs should have a moisture barrier installed to protect from ground moisture. The surface preparation of concrete should meet and conform to Joint NACE 6/SSPC-SP 13 standards and achieve a concrete surface profile of CSP 2 to CSP 5 as per ICRI Guideline No: 03732 for optimum performance.

Metal:

All surfaces should be clean and free from contamination. The surface should be assessed and treated in accordance with ISO 8504, Abrasive blast the surface to minimum NACE-2/SSPC SP-10/Sa 2.5, as per ISO 8501-1, for a visual assessment of surface cleanliness with an anchor profile of 2 to 3 mils (50 -75 microns). Soluble salts must be removed to an acceptable levels. Refer to NCSI surface preparation manual for detailed procedures for different types of substrates.

Prime all the joints, cracks & flashings with Nukote EP Prime II or Metal Prime II

APPLICATION:

For best results use a squeegee or notched trowel. Airless sprayer or phenolic resin core roller may be used but extra care should be taken not to trap air which may result in bubbles. Mix thoroughly and apply evenly over the entire deck. Application should not be stopped part way across an area. Each application should be done in one complete step. A continuous application will ensure a smooth and level coat with no lines or streaks to disfigure the deck coating. When Nukote BG mixed material begins to gel, broadcast 14-30 mesh rubber granules into the wet membrane or allow membrane to thicken until #1 or #2 washed dry sand, quartz, colored quartz (20 mesh, 6.5 Moh scale minimum hardness) can be broadcast without the aggregate sinking into the membrane. Time for thickening is dependent on atmospheric conditions especially temperature and humidity. Size of the aggregate should be decided based on the skid resistance requirement of the project

Allow each coat to cure (2-4 hours) before proceeding with subsequent coats to build up thickness. If more than 48 hours passes between coats, re-prime the surface with Nukote IC Prime, Inter-coat primer before proceeding. Allow 24 hours before permitting light pedestrian traffic and at least 72 hours before permitting heavy pedestrian or vehicular traffic on to the finished surface. Uncured Nukote BG is very sensitive to heat and moisture. Higher temperatures and/or high humidity will accelerate the cure time. Use caution in batch sizes and thickness of application. Low temperature and/or low humidity extend the cure time.

EQUIPMENT CLEAN UP:

Cured product may be disposed of without restriction. Uncured Isocyanate and resin portions should be mixed together and disposed of in accordance with local regulations. Containers should be disposed of according to local environmental laws and ordinances.

LIMITATIONS:

Do not open until ready to use, and store in a sealed container after opening. Should be used only as a base membrane. Nukote BG is not UV stable and must be top coated. Not designed to withstand direct wear and abrasion. Use recommended top coat suitable for the type of application Containers that have been opened must be used as soon as possible. Any off ratio mixing of the product will affect the properties and the product may not cure. The following conditions must not be coated with Nukote BG. Products deck coating systems or products: on grade or below grade slabs, split slabs with buried membrane, sandwich slabs with insulation, slabs over unvented metal pan, suspended pool decks, swimming pools, lightweight concrete, asphalt surfaces and asphalt overlays Do not dilute under any circumstance.

WARNING:

This product contains Isocyanate and curatives
