I. INTRODUCTION: HYDRO-SEAL 75 epoxy waterproofing
eliminates most seepage and moisture when applied to interior and exterior above
and below grade problem masonry. It forms a positive, high quality, integral
protective barrier against mass water penetration. It resists 40 P.S.I. hydrostatic
pressure, an amount ten times greater than needed to pass Federal Specification
TT-P-001411. Hydro-Seal 75 is a hydrophobic "breathing" type epoxy, which allows
vapor transmission to the highest degree in the industry (up to 1.75
permeability ASTM d 1653). It is solvent free, odorless, non-flammable,
relatively non-toxic. Is packaged, "ready-to-use" in two equal component
packages marked "A" and "B"; combined just prior to use.
II. DESCRIPTION: HYDRO-SEAL 75 epoxy waterproofing,
a two component heavy bodied water based epoxy, is designed to combine
flexibility with the hardness of epoxy resin. HYRDO-SEAL 75 modified coating is
based upon a carefully balanced ratio of fillers, water extended resins, and
hardeners.
III. How HYDRO-SEAL 75 Waterproofs:
A. Hydro-Seal 75 penetrates deep into these surface capillaries, cross
linking and forming a water insoluble lining on the side walls, pores and
voids in the substrate, making them water repellant.
B. This lining robs the water of its capillary action and prevents
moisture from entering through the masonry.
C. Successive coats, each bonded to the previous coat, build up
sufficient density, cohesion and strength to render the surface "pinhole
free" and impervious to mass water penetration.
IV. USES : For use on interior and exterior masonry (concrete, brick,
masonry block, mortar, stucco, adobe, cast stone and sandstone) surfaces, both
above and below grade. Formulated for on site, two coat spray or roller
application, Hydro-Seal 75 forms a positive, high quality, integral protective
barrier against mass water penetration when minimum time, high pressure and
strength are major factors.

VII. PHYSICAL ANALYSIS AND TECHNICAL DATA:
|
Hydrostatic Pressure Resistance Testing
(Federal Specification TT-P-001411) |
| During the cure phase,
Hydro-Seal 75 polymers cross-link to create a macromolecule of extreme
durability that provides optimum resistance to severe below grade
hydrostatic pressure, a wide variety of chemicals, and other environmental
conditions. |
| Testing Procedure: Two coats
of Hydro-Seal 75 was given to the outer surface of a 8"X8"X8" concrete
corner block (Federal Specification SS-C-621, Type 1, Class 3).The coating
is applied at the rate of 100 sq. feet per gallon allowing 24 hours air
dry between coats. A clock is mounted on a test stand, Fig. 1 and 2 and a
full water level is maintained for 7 days. At the end of this period, 4
psi pressure is applied and maintained for one half hour. The pressure is
released for 24 hours and then repeated for another half hour. (with
pictures) To effect a more severe condition, the pressure was increased
into 10 psi increments for one half hour. At 40 psi, the block burst with
no water seepage observed. |

| EFFLORESCENCE CONTROL |
The passage of water through
masonry units dissolves free lime and other salts of sodium, calcium or
potassium, carrying these salts in the outer surface. The salts then
crystallize to form efflorescence, an objectionable discoloration of the
surface. Hydro-Seal 75 prevents the major cause of efflorescence deposits. |

Since there are no toxic or
odorous solvents, Hydro-Seal 75 is used in occupied areas, including
schools and hospitals without discomfort. It is also ecologically safe and
acceptable. |

X. APPLICATION
A. COVERAGE:
1. TYPE OF MASONRY This chart assumes the masonry to be in good
general condition. Old masonry, however, often becomes more porous after
long exposure and weathering. Steam cleaning, sandblasting and acid
etching will also make masonry more porous. These recommendations,
therefore, will have to be adjusted on the job to the condition of the
masonry. When estimating coverage, allow 10% for overspray. Winds of
over 15 MPH will result in a further loss of material when spraying.

B. SUBSTRATE PREPARATION:
1. NEW CONCRETE:
a) Must be cured a minimum of 28 days.
b) Modern building
methods incorporate the use of curing compounds, hardening agents,
and bond-breaking compounds, all of these materials can seriously
affect the bond of Hydro-Seal 75. Should
be free of curing compounds.
2. OLD CONCRETE:
a)
Prepare and abrade substrate by
removing all foreign material such as preservatives, wax, sealers,
paint, hardeners, etc
that
would prevent proper hydration and bonding.
Use TSP and water.
b)
Pre-dampen surface. Normal cleaning
with TSP and water will pre-dampen surface enough. Be sure to rinse
surface with clear water to neutralize after washing with TSP and
water.
c) Fill holes and cracks.
Level uneven areas. For concrete leveling
and patching use Northern Industries' Epoxy Mortar System consisting
of Portland cement, Hydro-Seal 75 and fine sand.
C. APPLICATION
1. PREPARATION OF MATERIAL: Hydro-Seal 75 is a two
component material which requires the
combining of resin and curing agent. Do not mix more of component A and
B than can be applied in one half hour.
| TEMPERATURE |
POT LIFE IN CONTAINER |
| 80 °
F |
25 minutes |
| 60 °
F |
40 minutes |
a) Ratio: 1 part resin; 1 part curing agent
b) Mix each part in their independent container.
(1) Component A
(a) Stir Component A three (3)
minutes with mechanical mixer to disperse any settled
filler.
(b) Clean mechanical mixer
(2) Component B
(a) Stir Component B for three (3) minutes to disperse
any settled filler.
(3) Combine equal volumes of Component A and Component B
together with a mechanical mixer for three (3) minutes or until
it reaches the consistency of heavy cream. Failure to mix
properly may cause excessive chalking of the coating and, in
extreme cases, the coating may not dry.
(4) HYDRO-SEAL 75 is a chemically-cured coating that will set
up in the container after the two components have been mixed, if
it is not used within a relatively short period
2. FIRST COAT: HYDRO-SEAL 75 WATERPROOFING:
a) Coverage:
(1) approximately 100 square feet per gallon on rough
surfaces
(2) approximately 125 square feet per gallon on smooth
surfaces.
b) Temperature: HYDRO-SEAL 75 WATERPROOFING should not be applied
at a surface temperature of less than 50°
F or when relative humidity is above 85%.
c) Tools: stiff nylon brush or a long (1 or 2 inch) nap roller
d) Procedure:
(1) Using a stiff nylon brush or a long nap roller, stroke in
different directions to fill all pinholes. It is important to
apply material liberally as recommended for optimum results.
(2) Allow two hours to dry at 70°
F or until dry to the touch. Longer drying times will be
required at temperatures below 70° F.
3. SECOND COAT: HYDRO-SEAL 75 WATERPROOFING:
a) Coverage
(1) Approximately 135 square feet per gallon on rough
surfaces.
(2) Approximately 150 square feet per gallon on smooth
surfaces.
b) Cure Times
(1) Surface area will be cured properly after twenty-four
hours at 70° F and 50% R
H.
(2) Lower temperatures will require proportionally longer
cure times.
4. GENERAL PRECAUTIONS:
a)
Do not mix more of the material than can be applied within 40
minutes @ 72 ° F. Warmer temperatures
decrease the pot life. Under no circumstance can the mixed material
be tempered by the later addition of water.
b)
Do not apply at temperatures below 50°
F.
c)
Do not apply if there is a threat of rain within three hours
after application. Do not apply over any prior paints or coatings.
XI. CLEAN UP:
HYDRO-SEAL 75 is washed from tools and
equipment with warm water. Precautions should be taken to avoid solidification
of the coating on tools or equipment. Clean tools, hands, spillage or drippings
immediately or it will be extremely difficult to remove.
XII. PACKAGING:
supplied in a two package kit
(Component A and Component B): Available in 1, 6, and 10 gallon kits.
