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: Aromatic Hydro-glaze Interior Wall and Floor System is comprised of a
primer and second coat of Hydro-Seal 75 as well as third and fourth finish coats of NI-12
Aromatic Moisture-Curing Polyurethane. Hydro-Seal 75 is a two component thermoset, heavy
bodied, fluid applied, water soluble, solvent free, odor free, epoxy.

The higher the humidity and the temperature, the faster NI-12 will cure. Under normal
conditions of 60° F to 90° F and
relative humidity above 35%, NI-12 can be walked on 5-12 hours after application. 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.

D. 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.
1. Metal surfaces: should be prepared with a solution of phosphoric acid and
neutralized with water.
2. Concrete surfaces
a) New: Should be at least 28 days cured prior to application of seamless flooring
materials and free of sealers, curing compounds, oil, grease, hydrostatic pressure and
moisture transmission. Should be light steel troweled, smooth and level.
b) Old: Must be clean, free of paint, stain or other foreign material that would
prevent proper hydration and bonding. Patch and Level with Hydro-Seal 75 Epoxy Mortar on
concrete:
(1) Thickness
(a) Over 1/4": Add fine sand to Epoxy Mortar System to eliminate cracking.
(i) Mixing Ratio by volume: More sand is needed
for thicker applications. Up to a ratio of: 3 parts sand, 1 part cement, 1 part mixed
Hydro-Seal 75 for 1/2 " to 3/4" patch.
(b) Under 1/4": Epoxy Mortar System
(i) Mixing Ratio by volume: Three (3) parts
cement to one (1) part mixed Hydro-Seal 75 Epoxy
(2) Tools ( and additional materials):
(a) a straightedge trowel,
(b) Portland Cement
(c) Fine sand if needed
(3) Procedure:
(a) Fill and smooth all cracks with Mortar System as a scrape and seal coat
(b) Prepare rough, porous or contaminated surfaces that are deteriorating by filling
and repair them with the Epoxy Mortar System.
(c) Dry (1) hour at 70° F and 50% humidity.
3. Wood substrate: should be exterior grade plywood or
particleboard. Particle board should meet requirements of FHA use of materials bulletin UM
28 A. Wood/Particle Board. Fiberglass tape joints and fill nail holes:
(1) Tools:
(a) 4" Wide straight edge Putty Knife or straight edge trowel
(b) 4" Northern fiberglass tape
(2) Mixing Ratio: 2 parts cement, 1 part mixed Hydro-Seal 75
(3) Procedure
(a) Apply Epoxy Mortar System over joints as smoothly as possible ( feather edging)
(b) Lay Northern Industries fiberglass tape into the mortared joints.
(c) Apply additional Epoxy Mortar over fiberglass tape as smoothly as possible (Feather
edging)
(d) Fill all nail holes with same mixture
E. Installation Procedure
1. Mask all adjacent surfaces
2. First and second coats of Hydro-Seal 75:
a) Coverage: 100 to 120 sq. ft. per gallon
b) Tools (choice of):
(1) 3/8" or 1/2" Nap Roller or
(2) Brush or
(3) Spray equipment: "Graco Airless Spray Gun #208-327, Tip #163-817. Pump
#226-175. Equipped with an accessory to monitor the fluid pressure which shuts off
automatically if outside the pressure setting compressor (minimum) 8 H.P. flow, fluid oz.
NOTE: Other models of equipment are available to suit operational needs.
c) Preparation of Material
(1) Before blending, each component should be mixed
individually for a period of 5 minutes with a mechanical mixer.
(2) Mix components together in a one to one ratio using equal amounts of A component
and B component. Blend for 3 minutes. Please Note: Pot life is approx. 40 minutes.
3. FINISH COATS: Aromatic Polyurethane: NI-12
a) Tools: 3/8" or 1/4" nap roller and tray
b) Preparation of Material: For faster drying NI-12 Aromatic Standard Catalyst can be
added
c) Procedure: apply from tray in even strokes

IX. STORAGE:
A. 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.
B. 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.
