DESCRIPTION: |
|
SUPERIOR LIQUID BINDER
is a low viscosity, two component epoxy designed
specifically to be mixed with select gradations of dry
silica sands to form an epoxy mortar system for
repairing spalled areas and chuckholes, forming
overlays, establishing grades and use in other concrete
restoration and preservation applications. This mortar
system possesses tensile, compressive and flexural
strengths several times greater than the concrete being
repaired. |
|
USES: |
| Binder for wear
resistant floor resurfacing.
Binder for patching
mortars.
Bedding mortar for
acid-proof brick and tile.
Protective, waterproof
coating.
Non-shrink grouts for
settling and leveling machinery. |
|
ADVANTAGES: |
| Superior bonding
properties.
Low viscosity.
High strength.
100% solids.
Moisture tolerant. |
|
SURFACE
PREPARATION: |
| Bare, clean, dry and
structurally sound concrete surfaces are important to
permit intimate welding contact of SUPERIOR LIQUID
BINDER. The presence of grease, oil, wax, parting
agents, organic coatings, direct loose particles,
erosion or efflorescence will be detrimental and must be
removed. This is equally true for any chemical
treatments or additives used in the original
installation of the concrete substrate. Such possible
conditions should be predetermined and removed prior to
the application of SUPERIOR LIQUID BINDER mortar or
coating.
New Concrete:
Application should not be made until the concrete is
fully cured. Washing with a solution of 10% muriatic
acid, followed by thorough rinsing and neutralization
with clear water, is highly recommended.
Dense (Steel Troweled)
Surfaces: Abrade or roughen by sandblasting or wire
brushing - or wash with muriatic acid as above. Remove
all dust etc. accumulated by mechanical cleaning.
Old Concrete:
Procedures, as outlined above, should be observed. Clean
mechanically, by sand blasting, wire brushing, grinding
or chipping. Restrict chipping only to the removal of
disintegrated and spalled areas, to minimize the
possible development of new superficial cracks. Remove
all dust, dirt, and loosely bonded matter resulting from
all mechanical cleaning. Acid washing, as indicated
above, is also highly recommended to remove all foreign
residues. |
|
MIXING
AND APPLICATION: |
|
Mix thoroughly 2 parts
by volume of part A and 1 part by volume of part B.
Prime the surface to be treated with the neat epoxy.
Prepare the mortar system by adding 3-3 ˝ gallons of
clean, dry sand to each gallon of epoxy mix. Preferred
types of sand are: hard, high grade silica sands such as
Ottawa Flintshot, Mission, or their equivalents, Emery
or other forms of Alumina, and Silicon Carbide. If a
blend of sand is used, mix the sands together prior to
adding the epoxy. Blend the epoxy and sand until the
sand is thoroughly wetted. Screed the mortar out onto
the previously primed area, rake it to distribute, then
compact and trowel to finish. Blending may be
accomplished by using a heavy duty, slow speed 1/2"
electric drill with a paddle, a Kol mixer or a mortar
pan and concrete hoe. |
|
LIMITATIONS: |
| Do NOT apply when
temperature is below 50°F.
Do NOT apply to latex
modified mortar or concrete. |
|
CLEAN
UP: |
| Clean tools and
equipment immediately with a suitable solvent such as
xylene or lacquer thinner. |
