FUSION-CRETE® I LIQUID and FUSION-CRETE® II CRYSTALS are
both high-quality copolymer products which are used in very much
the same manner. The liquid product or the powdered product is first
mixed with the appropriate amount of water to make what we refer
to as the "pre-mix" solution. The amount of water that
will be added to each of these products varies, dependent upon what
type of work you intend to perform. There is a Mixing Ratio Chart
contained in the Instructions For Use of these products, as well
as on each five-gallon pail of these products. These Mixing Ratio
Charts give the amount of water to be added to the product (by volume)
in order to prepare the "pre-mix" solution for numerous
applications, as well as the amount of cement and sand to be used
in the application. In deeper applications, where gravel may be
added, both the amount and the maximum size of the gravel are indicated
on the Mixing Ratio Chart. While the liquid product is quite soluble
in water, the powdered product is defined as "dispersible and
redispersible"; this means that the powdered product may be
dispersed in water and redispersed after settling occurs. Consequently,
the powdered product, after having been mixed with water, will require
stirring from time to time in order to redisperse the powder in
the "pre-mix" solution.
The dry repair and/or
coating mixture of cement and sand (with or without gravel) is mixed
separately in the appropriate ratio which is found on the Mixing
Ratio Chart for the desired application you wish to perform. Subsequently,
the "pre-mix" solution is slowly added to the dry mixture
until the desired consistency is achieved. The "pre-mix"
solution will be the ONLY liquid added to the dry mixture of cement
and sand. Water should never be added to the dry mixture separately.
Dry mixtures are recommended for projects such as curb repairs because
these mixtures may be feathered into broken, jagged surfaces and
the construction of forms and major demolition become unnecessary.
Prior to the application
of a repair or coating mixture, the repair surface must be thoroughly
cleaned and prepared for the repair materials. (See the Instructions
For Use for this information.) Just prior to applying the repair
mixture, the repair area must be "primed", i.e., a bonding
coat applied. In mild climates with little movement, expansion or
contraction, the "pre-mix" solution may be used as the
primer or bonding coat. However, we strongly recommend that a cementitious
slurry coat be used as the bonding coat or primer because this will
assure a substantially better bond between the existing surface
and the repair/coating application. A cementitious bonding coat
may easily be prepared by adding one part of cement and one or two
parts of sand to some of the "pre-mix" solution, bringing
it to a paintable consistency. This bonding coat may then be applied
with a paint brush or wallpaper paste brush just prior to the application
of the repair/coating mixture. It is important that the bonding
coat be either wet or tacky when the repair/coating mixture is applied.
If the bonding coat has dried before the application of the repair/coating
mixture, a second bonding coat should be applied prior to the application
of the repair/coating mixture in order to assure a strong, permanent
bond.
The "pre-mix"
solution may also be used to retemper the repair/coating mixture
if it has gotten too dry from the sun and/or heat. The "pre-mix"
solution may also be used to facilitate the final finishing (trowelling,
brooming, sponging, etc.) by placing some of this "pre-mix"
solution in a plastic spray bottle (Hudson sprayer for large areas)
and "misting" some "pre-mix" solution on the
surface immediately prior to the final finishing. Other procedures
and techniques for the use of FUSION-CRETE® I LIQUID and FUSION-CRETE®
II CRYSTALS are discussed in the Instructions For Use and shown
in our videos.
FUSION-CRETE® 5-MINUTE
CONCRETE is a totally different, two-component "magnesium/phosphate"
product that is used in a substantially different manner. Minimal
surface preparation is required. Generally, brushing or sweeping
is all that may be required, unless there are substances such as
oil, grease, gum or other materials in the repair area that may
interfere with a good bond. If this is evident, clean the surface(s)
appropriately. Potholes require virtually no surface preparation
because the repair material will be fully contained.
Two (2) to three (3)
parts of sand (by volume) may first be added to Component "B",
Dry Cement Compound, and thoroughly mixed. The green-colored Component
"A", Liquid Activator, may be used as a "primer"
when repairing vertical or shallow horizontal repair areas. This
may be accomplished simply by painting the Liquid Activator on the
surface just prior to applying the repair mixture. This will not
be necessary in filling potholes because, as previously stated,
the repair material will be fully contained.
As its name implies,
FUSION-CRETE® 5-MINUTE CONCRETE is an extremely fast-setting
concrete and it is important that you have the necessary manpower
available and that, once commenced, you work very quickly so that
you can accomplish the desired repair properly. In normal circumstances,
this material becomes rock-hard in five (5) minutes following the
addition of the Liquid Activator to the dry mixture of Component
"B" and sand; however, you may delay the hardening time
by as much as a few minutes by using more of the Liquid Activator
in the mixture. Before using this product on an actual repair site,
we suggest that you experiment with this product to properly prepare
yourself.
Once the sand has been
added to Component "B" and thoroughly mixed, you may prime
the repair area first with the Liquid Activator and then quickly
add the same amount of Liquid Activator (by volume) as the amount
of Component "B" used. Quickly and very thoroughly mix
the Liquid Activator with the dry mix of Component "B"
and sand using rubber-gloved hands. If the mixture appears too dry,
you may add a very small additional amount of Liquid Activator.
At first, the mixture will develop a dough-like consistency. You
may then apply the
appropriate amount of this material to the repair area with your
gloved hands and you may immediately commence the finishing and/or
shaping procedures with the use of a steel trowel and/or sponge
first dampened with clean water. While a trowel may be useful in
compacting the material into the repair area, a water-dampened sponge
will be very useful in achieving a nice finish or creating a radius
to match an existing radius in the repair area. A chemical induction
results from the combination of these materials, causing a substantial
increase in heat and the release of a minimal amount of free ammonia.
If used indoors, additional ventilation might be desirable. This
is unnecessary if the product is used outdoors. Always remember
to work very quickly with this product because it will set up in
approximately five (5) minutes and will develop a compressive strength
of as much as 4,500 psi in approximately two (2) hours! If used
to fill a pothole in a roadway, the roadway may be opened to heavy
traffic in only five (5) minutes after completing the repair. This
material will also set up under water. If it is raining heavily
and the pothole to be repaired is full of water, the FUSION-CRETE®
5-MINUTE CONCRETE may be mixed under cover and then dumped into
the pothole. Being substantially heavier than water, the repair
material will displace the water and, when it reaches street level,
may be flattened and finished with a trowel dampened with water
while the repair area is covered with a tent or a hand-held umbrella.
Sometimes, more than one application may be required to reach the
street level. Again, this area may be opened to heavy vehicular
traffic (buses and big-rigs included) five (5) minutes following
completion of the repair.
This product is very useful to Public Works/Street Maintenance Departments
for the repairs of potholes and/or other damage in peak traffic
areas during rainstorms. Additional information on this amazing
product is included in the Instructions For Use pamphlet.
