Hydro-Glaze Aromatic

I. INTRODUCTION

Aromatic Hydro-glaze Interior Wall and Floor System is an aromatic polyurethane system that is impervious to most chemical attack and bacteria penetration. The system can be applied to most sound substrates including concrete, plywood, particle board, steel decks and other areas as an interior systems where scrub resistance and high where it is necessary. The Aromatic Hydro-glaze System provides superior scratch resistance and is perfect for areas where lowest possible material costs are required.

II. DESCRIPTION

NI-12 can be buffed and re-coated when tack free to foil in 3-10 hours after application. NI-12 requires approximately one hour or less to "dry to touch", three to four hours to " harden" and about 7 days to cure.

SUBSTRATE PREPARATION: Prepare and abrade substrate, removing all foreign material such as preservatives, waxes, sealers, paint, hardeners, etc. Substrate should be wood, concrete or metal: having a true surface within 1/8 inch (+/-) 10 feet in any direction. Substrate temperature must be no lower than 50° F and maintained during the installation and curing period. For concrete leveling and patching use Northern Industries' Epoxy Mortar System (cement and Hydro-Seal 75 and fine sand. For Plywood or Particleboard installations, always use the Epoxy Mortar System and fiberglass tape for taping joints and the mortar for filling nail holes.

IX. STORAGE

1. NI-12 Aromatic Polyurethane should be stored in a cool, dry and safe area. Always rotate inventory, using oldest materials first. Shelf life is approximately 4 months in a factory sealed container.
2. Hydro-Seal 75: Store material in dry area; Keep from freezing. Prevent damage to containers. Do not store for long periods in direct sunlight. Protect from the environment or potential damage by other trades.

X. MAINTENANCE

The maintenance costs of Northern seamless flooring and wall coating is approximately half that required of other resilient floor products and wall coatings. Northern Seamless Flooring needs no waxing and will give you lasting beauty at the lowest possible maintenance cost. There is no floor covering, whether it be untreated, waxed, or plastic-surfaced, that is as simple to maintain as Northern Seamless. A "waxed" or "treated" surface is more difficult to maintain than the natural surface of Northern Seamless.

PERIODIC CLEANING:DO NOT USE WAX OR POLISH ON NORTHERN SEAMLESS FLOORS. Remove the day-to-day dust and dirt with a "treated" dust mop or damp mop. Dry buffing, with a stiff bristled polishing brush or an electric polishing machine, will loosen most all other "lodged-on" dirt, which can then be removed with a dry mop or vacuum cleaner. Damp mop with clean warm water so you are not re-depositing soil to the surface. Chemically clear, water-soluble detergent (dishwashing Detergent such as Cascade) should be added to clean, warm water and applied to floor. All dirty detergent water is to be removed, using either mechanical vacuum, pickup equipment, clean mop or squeegee. Scrubbing with an electric scrubbing machine is necessary, only if floor has been neglected and surface soil is not removable by above methods.

XI. PRECAUTIONS

A Northern Seamless Floor is "tender" through the first 30 days after installation. Dirt and grit act as abrasives, and must be removed immediately.

XII. REGLAZING

Northern Seamless Aromatic Hydro-Glaze Sytem can be reglazed. In order to do a proper job, the floor must be recoated before wear has exposed the chips. Wash floor with T.S.P. (Tri-Sodium Phosphate) and warm water (1 cup T.S.P. to 1 gallon water). Rinse thoroughly with clean, cool water. When dry, buff with .000 steel wool pads. Vacuum completely. Apply finish coats of NI-12 using 1/4" nap roller.
