EPOXY GROUT
DESCRIPTION
TECHNICAL DATA CP-20
OVERDRIVE ®
OverDrive ® is a specially developed epoxy grout for rebuilding
severely eroded concrete floors. Because of its tremendous
bonding and load-bearing properties, this product yields an
excellent base for the application of OverKrete ® , OverKote ® ,
Overkote ® Plus, FlorClad , or other products manufactured by
Rust-Oleum.
FEATURES AND BENEFITS
Freedom from porosity: Porosity is the most common cause of
flooring failures. OverDrive ® is nonporous and does not require
a sealer coat to prevent chemical penetration to the concrete.
Sealer coats are subject to breakdown due to wear, fracture,
or chemical attack. When this occurs on porous systems, the
underlying concrete is attacked by the chemicals and the
coating starts debonding.
• Adhesion to new concrete: Bonds to 10 day old concrete at
70°F.
• Adhesion to damp concrete: OverDrive ® epoxy grout has
a tenacious adhesion to concrete. The bond strength of
OverDrive ® exceeds the tensile and shear strengths of the
concrete itself.
• OverDrive ® can be applied on high moisture and damp
concrete (with no standing water). Its bond strength
is lessened somewhat, but is still acceptable for most
applications. This unique characteristic of OverDrive ®
eliminates a major uncertainty in applying a grout system,
since moisture conditions are difficult to control in the field.
• Rapid turn around time: At application temperatures above
70°F, the OverDrive ® material can support foot traffic in 6-8
hours and is ready for coating or topping at that time.
FOR VERTICAL SURFACES
OverDrive ® is a fluid system and cannot be applied to vertical
surfaces. For vertical applications, consult our technical service
department.

PACKAGING
OverDrive ® is available in three standard kit sizes:
Kit Size Part A Part B
4 gal. kit 3 gal. (part fill) 1 gal.
20 gal. kit 15 gal. 5 gal.
60 gal. kit 45 gal. (drum) 15 gal.
COLORS
OverDrive ® is intended as an underlayment for coatings or
toppings, and is therefore unpigmented.
PRODUCT APPLICATION
APPLICATION
OverDrive ® can be applied with a trowel or spreader bar. With
temperatures ranging from 65-90°F, working time will be between
25 and 35 minutes. At temperatures above 90°F, working time
will be shorter (possibly requiring more application personnel or
smaller batch sizes).
SURFACE PREPARATION
NEW CONCRETE: Laitance must be removed by muriatic acid
etching, shotblasting, or sandblasting. On concrete that does not
take muriatic etching, shot blasting or sandblasting is required.
EXISTING CONCRETE: Concrete must be sound, and old coatings
and toppings must be removed. Concrete must be clean and
free of oil, wax, paint,and other contaminants. Water soluble
contaminants should be hosed off with water. Some water
insoluble materials are difficult to remove and may require
sandblasting, scabbling or other methods of removal.
MIXING EQUIPMENT
Mix with a 5 gal. electric bucket mixer having a side and bottom
scraper attached or a mortar mixer. This set-up will allow all the
material to be mixed in an even and consistent fashion.

PRODUCT APPLICATION
TECHNICAL DATA
OVERDRIVE ®
MIXING
The minimum temperature for application should be 65°F.
For low temperature applications, consult Rust-Oleum. Use
only motorized mixers. Hand mixing will produce inconsistent
results. For each 1 gal. of OverDrive ® (part A and part B mixed),
add 60 lbs. of aggregate (30 lbs. of 1/8-1/4 inch pea gravel
plus 30 lbs. of clean graded 30-40 mesh sand). This mix will
fill approximately 1/2 cubic foot area. The aggregate may be
purchased locally or from Rust-Oleum.
Pour part A (resin) and part B (hardener) into mixer. Mix for
about 30 seconds. Immediately add pea gravel and sand. Mix
only long enough to thoroughly disperse the aggregate (1.5 to
3.0 minutes). Immediately pour onto the concrete.
Because sand and gravel size will vary from region to region,
the recommended 30 lbs. of 1/8-1/4 inch pea gravel and 30
lbs. of sand is only a good starting point. If the mix is too wet,
more sand and gravel can be added or 480 silica sand can be
used. If the mix appears too dry, decrease the amount of sand
or gravel accordingly.
Note: Mixing ratios are supplied in kits and on container labels.
For additional adhesion of toppings to OverDrive ® , a silica
broadcast of 50 lbs. per 10 sq. ft. will provide an additional
tooth for binding a heavy duty system.
CLEAN UP
Xylene can be used to remove material from equipment if it is
cleaned before the material has started to set up; otherwise,
stronger solvents such as methylene chloride will be necessary.
If there are any questions on the use of this product, please
consult our technical service department.
SAFETY
OVERDRIVE contains amine curing agents. Avoid skin contact.
In case of eye contact or ingestion, contact a physician
immediately. In case of skin sensitivity to these materials, use
protective clothing and gloves.
MATERIAL SAFETY DATA SHEETS
Material Safety Data Sheets are available upon request. It
is strongly recommended that they be read by all persons
handling OverDrive ® .
