I. INTRODUCTION

NI-Dura Vinyl Chip Seamless Flooring System is a decorative, durable seamless system that can be applied to most sound substrates, including concrete, plywood, particle board, steel decks, etc. as an interior system where scrub resistance is necessary in combination with unusual decorative effects. Chips are broadcast to obtain an unlimited number of decorative finishes and color patterns. These decorative finishes provide a texture that helps to break up the plane of light reflection and diminishes substrate imperfections.

XI. MAINTENANCE

Northern Seamless Flooring is a flooring system that needs no waxing.

A. MAINTENANCE-COMMERCIAL: MAINTENANCE INSTRUCTION FOR NORTHERN FLOORS IN COMMERCIAL INSTALLATIONS Following the simple recommended maintenance instructions, a Northern floor will give you lasting beauty at lowest possible maintenance cost. There is no floor covering, untreated, waxed, or plastic-surfaced, that is as simple to maintain as Northern Seamless Obviously, ease-of-maintenance reduces costs. Thousands of Northern Seamless users are saving maintenance dollars every day and testimonial evidence can be shown which proves Northern Seamless Floors are saving owners as much as 50% percent or more on their old floor maintenance budgets. A "waxed" or "treated" surface 1 s more difficult to maintain than the natural surface of Northern Seamless

B. PERIODIC CLEANING

1. DO NOT USE WAX OR POLISH ON NORTHERN SEAMLESS FLOORS
2. Remove the day-to-day dust and dirt with a "treated" dust mop. (The larger the mop, the easier and faster the job) To remove dust and dirt on a day-to-day basis, use large dust mops treated with Dust Attractor or commercial vacuum cleaner.
3. Remove rubber heel marks, etc., with a dry rag or wet sponge: Black rubber marks can be removed with a clean rag or damp sponge.
4. 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.
5. When it becomes necessary to remove soil that is not removable with the above procedures, damp mop with a clean mop and clean warm water. If you elect to mop-rinse, keep your mop water clean so you are not redepositing soil to the surface When necessary, Northern Seamless should be wet cleaned. Chemically clear, water-soluble detergent (dishwashing Detergent such as Cascade) should be added to clean, warm water and applied to floor to emulsify surface soil. All dirty detergent water is to be removed, using either mechanical vacuum, pickup equipment, clean mop or squeegee.
6. Scrubbing with electric scrubbing machine is necessary, only if floor has been neglected and surface soil is not removable by above methods

C. PRECAUTIONS

1. When a Northern Floor is brand new, it is "tender". Every day it is down, through the first 30 days, it gets tougher, so give a Northern floor a little more attention through these early days of curing.
2. Should there be cigarette burns, repair them as soon as possible after they appear.
3. Grease, oil, or dirty water act as "lubricants" on the surface of Northern Seamless, thus making the surface slippery. If these are removed, (not just moved around) and the surface is kept clean, the chances of slipping are minimized.
4. Dirt and grit must be removed frequently, as they act as abrasives, shortening the life of the floor.

D. Reglazing: unlike waxed conventional flooring, one of the outstanding features of this remarkable Northern Seamless Floor is that it can be restored to its' original luster by reglazing, should this become necessary after years of wear.

XII. REGLAZING

Northern Seamless can be restored at any convenient time by reglazing.

A. HOW TO REGLAZE NORTHERN FLOORS

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

XIV. LAYDOWN ACRYLILC SEAMLESS FLOOR SYSTEM

A. INTRODUCTION

The flooring and wall coating industry has long sought a durable seamless waxless flooring system. Such a system should be easy to handle in application, resilient, waxless and extra durable.

Northern Industries, Inc. has combined the established properties of water-soluble epoxy and moisture cured urethane polymers to produce the ultimate in seamless flooring and wall coating systems.

Northern Seamless flooring and wall coating are tailored to fit your flooring and wall requirements whether residential, commercial, or industrial.

This offers virtually a limitless availability of color combinations that will adapt and compliment any decor.

In addition to being a high style custom floor, Seamless by Northern never needs wax, is completely resilient, is highly resistant to most mild acids and alkalis and to scuffing and scratching.

Residential and Light Commercial flooring consist of two component water-soluble odorless epoxy, prime and base coat. Water insoluble colorfast chips and two-part moisture cured urethane finish coats, having ultra violet inhibitors.

Heavy Commercial and Industrial flooring consists of two component water soluble odorless epoxy prime and base coats permanently coated fused ceramic light core aggregate and two part moisture cured urethane finish coats, having ultra violet inhibitors.

Commercial and Industrial Seal coat consists of pigmented two component water soluble odorless epoxy prime and base coat, and moisture cured urethane finish coats, having ultra violet inhibitors.

Decorative Wainscoat, Cove Base, and wall systems will consist of two component water soluble odorless epoxy, prime and base coat, water insoluble color fast chips and moisture cured urethane finish coats having ultra violet inhibitors.

Interior Glazed Wall Coating consists of pigmented two component water soluble odorless epoxy prime and base coats and moisture cured urethane finish coats having ultra violet inhibitors.

Exterior Masonry waterproof coating (over concrete, cement block, brick, or cinder block) consists of two component pigmented water soluble odorless epoxy prime and base coats and water soluble two component pigmented odorless epoxy finish coat. NOTE: (Application by brush, roller, or spray).

Interior-Exterior masonry aggregate color coat (over concrete, cement block, brick, or cinder block) consists of two component pigmented water soluble odorless prime and base coats permanently coated fused ceramic light core aggregate and two component water soluble translucent, odorless epoxy binder coat.

B. MAINTENANCE

Maintenance cost of Northern seamless flooring and wall coating is approximately half that required for other resilient floor products and wall coatings.
