b.
Remove oil, grease, wax, old paint with [Detergents, solvents or strippers] [Flame] from crack.
3.05 MIXING
Specifier Note: In warm conditions, if all of the resin and hardener (provided in kit by Abatron) are mixed at one time, they may
harden too quickly. In such conditions, or when smaller quantities are required, small amounts of resin and hardener should b e
mixed in the ratio indicated on the can label in a small container to avoid too fast hardening. Consult manufacturer's technical
literature or contact manufacturer for comprehensive mixing instructions.
A.
Mixture: Concrete Restoration:
1.
[ABOCRETE] [AboWeld 55-1] [AboWeld 8708-2] [AboCast 8005-6] [AboCast 8007-2].
a.
Pour resin and hardener in pail in accordance with manufacturer's recommended ratio.
b.
Mix thoroughly.
Specifier Note: The sand provided with the product is the grade used most often, but finer or coarser sand, grit, chips, pebb les or
gravel can be chosen to suit particular requirements. The addition of sand and aggregates is recommended, especially in thick er
sections, to reduce the coefficient of thermal expansion differences between resin and substratum. Thicker layers of unfilled resin
may separate or crack due to higher contraction/expansion in cold and warm weather. Excess of sand can proportionately reduce
tensile and flexural strength.
c.
Add [Provided] [Specified] sand to quantities [As recommended by manufacturer] [As directed by Architect
{ ----------------- }] [Specified] after 2 - 3 minutes of mixing.
Specifier Note: Fibrous fillers such as fiberglass or fabrics improve tensile and flexural properties. Rocks can be used as
fillers, preferably graded with gravel and sand, in larger cavities and cracks.
d.
Add [Fiberglass] [Fabric] [Rock] fillers in quantities as [Recommended by manufacturer] [Directed by Architect
{ ----------------- }] [Specified], mix thoroughly.
e.
Add [Dry concrete powder] [Color pigments] while stirring.
Specifier Note: Special handling or special formulations are available for very high or very low (even subfreezing) temperatures.
Consult the manufacturer for specific installations outside of the normal temperatures of application.
f.
Blend in [AboCure 7912-1] [Manufacturer recommended additive] in ratios as recommended by manufacturer.
Specifier Note: For thin layer applications, an induction period (the blend must rest in the mixing container for a period of time before use) is
recommended. This allows the resin/hardener reaction to progress to the point that the ambient moisture or CO 2 cannot affect it and
cause incomplete "oily" hardening. When the atmosphere is dry, or when heat is used for curing, or where ABOCRETE blend is
applied thick, the induction period is not necessary.
g.
B.
Induction Period: 5 - 10 minutes.
Mixture: Structural Crack Control:
1.
[AboJet-1] [AboJet-2] [AboJet 8610-1] [AboJet 8610-2] [AboJet 8610-3] [AboJet 8702-3].
Specifier Note: AboJet resins are sold in cans, pails or drums. AboJet 8610-1, 8610-2, 8610-3 and 8702-3 are also sold in
compartmented 10 fl oz cartridges. The cartridges are syringe-type containers that hold the resin and the hardener separated
by a diaphragm connected with a plunger that is pressed to break the diaphragm and mix the resin and hardener without
opening the cartridge. Select the dispensing method appropriate to the task.
a.
Measure and mix by hand resin and hardener in pail in accordance with manufacturer's recommended ratio.
6
b.

3.06 APPLICATION
Specifier Note: AboSolv can be added in any concentration to the ABOCRETE blend for use as a thin primer coating. The unfilled
resin/hardener blend can be diluted 2/1,1/1 or 1/2 with AboSolv and so rolled, brushed or sprayed as a primer for solventless
(filled or unfilled) resin/hardener blend. For thick coating or patches, no more than 5 - 6% solvent is recommended. Consult
manufacturer's technical literature or contact manufacturer for comprehensive application instructions.
A.
Primer Coating:
1.
[ABOCRETE] [AboW eld 55-1] [AboWeld 8708-2] [AboCast 8005-6] [AboCast 8007-2].
Specifier Note: Refer to manufacturer's recommendations for prime coat requirements specific to each product.
a.
Dilute ABOCRETE blend with AboSolv [2/1] [1/1] [1/2] [As recommended by manufacturer] [As directed by
Architect { ----------------- }] [No greater than 5 - 6%].
Specifier. Note: A primer is not necessary with AboWeld 55-1. However, on surfaces that are too porous or difficult to wet,
PrimKote 8006-1 can be used to ensure best adhesion.
b.
2.
B.
Prime with PrimKote 8006-1.
[Roll] [Brush] [Spray] primer in accordance with manufacturer's recommendations.
Application: Concrete Restoration:
1.
[ABOCRETE] [AboWeld 55-1] [AboWeld 8708-2] [AboCast 8005-6] [AboCast 8007-2].
Specifier Note: In general, the larger the bulk, the faster the hardening. The thinner the layer, the slower the hardening. The higher
the temperature, the faster the hardening. The lower the temperature, the slower the hardening. Normal temperatures of
application are between 60 degrees F - 85 degrees F (15 - 29 degrees C).
a.
Ensure temperature of application is [> 60 degrees F (15 degrees C) and < 85 degrees F (29 degrees C)] [ --------------degrees F ( -------------- degrees C)].
Specifier Note: A blend with sand, gravel or aggregate can be spread, troweled, poured or cast into forms. A blend without sa nd
can be poured, spread, brushed or sprayed.
b.
[Spread] [Trowel] [Pour] [Cast into forms] [Brush] [Spray] blend in accordance with manufacturer's
recommendations.
Specifier Note: Use the following article for a non-slip floor application.
c.
Broadcast sand onto surface to cover resin completely; sweep off excess sand after resin hardens.
d.
Allow application to harden.
Specifier Note: Curing is called the completed reaction, or the progression toward the point at which the optimum properties
(rigidity, physical strength, chemical and heat resistance) have been reached. After hardening, the curing reaction continues for days or
weeks, by itself, at room temperature, or it can be accelerated to a few hours or a few minutes depending on the product and
application with heating.
C.
Application: Structural Crack Repair:
1.
[AboJet-1] [AboJet-2] [AboJet 8610-1] [AboJet 8610-2] [AboJet 8610-3] [AboJet 8702-3].
Specifier Note: Vertical surfaces will require injection ports; for horizontal surfaces the process may be a filling procedur e by
pouring or troweling, so that ports and caulking guns may not be needed.
a.
If backside of wall is exposed, seal cracked surface along backside of [Wall] [ -------------- ] with [AboWeld 55-1] [ --------------]
to contain AboJet injected from front side.
b.
Predrill holes for insertion of injection ports.
c.
Insert 2 inch - 3 inch (51 - 76 mm) long x 1/4 inch (6.4 mm) diameter copper tubing sections or plastic ports
(injection ports) into crack on front side of wall starting from bottom of crack every 8 inches - 12 inches (203
- 305 mm).
d.
Seal crack around ports and between them with [AboWeld 55-1] [AboWeld 8708-2].
Specifier Note: Blending fillers such as sand with the resin/hardener mix before injecting is useful for larger cracks (wider than 1/8
inch (3.2 mm)) to compensate for the different coefficients of thermal expansion between the resin and surrounding material.
e.
Mix in fillers to resin/hardener blend.
7
f.
Inject blend through lowest port, until resin starts oozing from port above that.
g.
Crimp lowest port shut to prevent resin backflow, and inject resin through next p ort above, until resin
