Description:
A liquid admixture comprised of acrylic polymers and modifiers which when
added to any portland cement mixture, promotes a substantial increase in
adhesion of the mixture.
OCTOBLEN is used to aid in curing the new mortar mix, while
substantially increasing flexural and tensile strengths. The resulting cement
mortar will have an increased resistance to
freeze-thaw stress, spalling, cracking, abrasion, dusting and impact. The
workability of the OCTOBLEN modified mortar is improved, while prewetting
and after-curing of the new surface is greatly reduced. The physical properties
created by addition of OCTOBLEN are not reversible once cured, even in
the presence of constant water. Therefore, OCTOBLEN may be used in any
interior or exterior portland cement application.
Primarily used as an admixture to interlock the new mortar mix to itself and
to the existing surface, it can be applied as a slurry bonding membrane between
an old and new surface, where the new layer is less than 1 inch (2.5 cm)
thickness.
Uses:
INSTALLATION
Surface Preparation:
Surface to be treated must be cleaned of any film, scale, loose material,
oils, grease, dust, dirt, laitance, efflorescence, oil-based curing membranes or
form release agents, paint, unsound concrete and any other material that will
prohibit bond. Surface preparation may be accomplished by sand blast, water
blast, surface scarification, grinding or chemical methods.
On days when temperatures exceed 80ºF (27°C), the prepared surface should
be thoroughly dampened (not saturated) with water. On cool days, prewetting is
not required.
Mixing:
Mechanical mixing is recommended. Use an electric drill motor and mixing
paddle or mortar mixer. For optimum results, OCTOBLEN should be used as
the gauging liquid for cement slurries, overhead repairs and traffic bearing
applications. For maximum bond of vertical patches and wall plasters, the
gauging liquid should include at least 1 gallon (3.8 L) of OCTOBLEN for
each 50 pounds (22.7 kg) of portland cement in the mixture. Always premix the
gauging liquid before adding it to the premixed dry materials. Place an
appropriate portion of the premixed gauging liquid in a clean mixing container,
add measured powder and add balance of required liquid while mixing to bring to
an application consistency.
Application:
As a Slurry: Neat OCTOBLEN may be spread over existing surfaces
for bonding to concrete construction joints. For lighter toppings it is mixed
with a portion of the mortar powder or straight portland cement to make a 1/8
inch (3.2 mm) bonding slurry coat or membrane to be scrubbed into the existing
surface. Topping mixes should be placed while the slurry bond coat is moist.
Construction joints must be placed immediately following the neat placement of OCTOBLEN.
As a Patch or Topping Admixture: Pack firmly and quickly without any
more working force than is necessary. Mix only as much material as can be placed
in 30 minutes (40 minutes in cool weather). Clean trowel or narrow metal
straight edge (screed) the concrete surface frequently. When screeding large
areas, keep build-up of material ahead of the screed and vibrate with short
strokes. Finishing with a brush dipped in a mixture of equal parts water and OCTOBLEN
will produce a smooth dense surface. Raking with a stiff brush before final set
will produce a rough, non-slip surface.
With Cement Paints: Use OCTOBLEN when applying cement paints
over previous cement coatings or over monolithic concrete to achieve lasting
adhesion. OCTOBLEN will also aid cure and color uniformity, and eliminate
the need for surface wetting.
Prepare liquid comprised of equal parts water and OCTOBLEN. Add powder
to liquid while mixing. Bring to a heavy paste; allow to sit 20 to 30 minutes;
thin to whipped cream consistency and apply material. Approximately 2 quarts
(1.9 L) of OCTOBLEN per 25 lbs. (11.3 kg) of cement paint may be used. An
alternate method to improve adhesion of a cementitious coating over a monolithic
surface is to roll on a heavy slurry of OCTOBLEN and mortar mix prior to
applying the mixture. MIXING POWDER DIRECTLY INTO THE OCTOBLEN PROVIDES
THE BEST RESULTS.
As an Admixture in Coatings: Mix only as much material as can be
troweled or sprayed in 1 hour.
Curing:
In cool, humid weather, OCTOBLEN modified mixes are self curing. When
drying is rapid due to hot, fry air or forced ventilation, apply a moist cure
for 48 hours for vertical applications, and for 4 days for traffic bearing
areas. DO NOT USE SOLVENT BASED CURING COMPOUNDS.
Clean-up:
Cleanup must be done immediately due to high bonding characteristics of OCTOBLEN
modified mortars. Clean equipment with water and a mild detergent.
Packaging:
OCTOBLEN is packaged 4 gallons (15.1 L) per case, in 5 gallon (18.9 L)
pails and 55 gallon (208.2 L) drums. Larger bulk packaging is available and may
be sized to meet our customers’ needs. Consult with IPA’s Engineering
Department at 800-523-3834.
Shelf Life: One year
Limitations:
OCTOBLEN modified portland cement mixtures are more difficult to
finish than straight water and powder mortar mixes. DO NOT apply solvent
containing compounds or coatings over OCTOBLEN modified mixtures. DO NOT
use with air-entraining cements. OCTOBLEN should not be applied at
ambient substrate and air temperatures lower than 45°F (7°C).
