7.2.3.4 Installation Instructions
urface Preparation
S
The surface to be repaired must be
clean, dry, and free of oil, grease and
oose matter. The bonding surface
l
should be roughened, using a small
hipping hammer or bushing tool, swept
c
clean and blown with clean, dry, oil-free
ompressed air, or vacuumed clean.
c
Where the patch will terminate, the
concrete must be sawcut and chipped
out 1/4" deep.
No priming is required with RM 710 EP,
so installation is quick, easy and
economical.
Temperature
RM 710 EP should be stored at
temperatures between 50°F and 90°F
(10°C and 32°C) prior to use.
Substrate temperatures may be
between 30°F and 80°F(–1°C and
27°C).
Mixing
Proper mixing is critical when installing
epoxy repair mortars.
Do not mix more mortar than
can be applied in 30 minutes at 35°F
(2°C), or 5 minutes at 70°F (21°C). Drain
he contents of Part B completely into a
t
clean mixing container. Then drain the
ontents of Part A into the same
c
container. Mix the liquids until the
esultant mixture is free of streaking.
r
Next, add the aggregate, a little at a
time, while mixing with a mortar mixer or
a drill with a mixing paddle. Mix until
uniform, being sure that there is no dry
aggregate on the bottom or sides of the
pail. Do Not Mix Partial Units. Failure to
combine components in the proper
ratios can r
esult in poor cure or no cure.
Up to 1 lb of cement colorant may be
added to color patch.
Troweling
For large patches, apply RM 710 EP
mortar in 2 foot wide strips. Lattice
boards will help ensure proper
thickness. Spread and finish with a
rectangular steel trowel, taking care
to minimize trowel marks. Be sure
the edges of patch are flush with the
surrounding concrete. For smaller
patches, a trowel alone may be
sufficient. Trowels may be coated
with a commercial solvent such as
mineral spirits, to give the finished
work a smoother appearance.
aintenance
M
RM 710 EP may be cleaned with most
floor cleaning detergents. Aggressive
olvents should be avoided.
s
Floor Cleaning
Caution: Some cleaners may affect the
color of the floor installed.
Test each cleaner in a small area,
utilizing your cleaning technique.
If no ill effects are noted, you can
continue to clean with the product and
process tested.
Recoat or T
opcoating
No recoating or topcoating is necessary.
However, if you opt to topcoat the
applied mortar, allow it to cure before
topcoating. Many epoxies and
urethanes can be used. Contact your
Hilti Sales Representative for suitable
topcoat selections.
