RS
is an all-weather inorganic cementitious material that is self-bonding. RS provides superior set, bond and
compressive properties, return to service in as little as10-15 minutes for walk
time and a 45 minute time for heavy traffic. RS has less impact on the environment, with
no off-gassing, and performs excellently in freezing temperatures, such as freezer
floors. RS
can be used as a replacement
anywhere a fast-setting, high-strength concrete and/or mortar is required. RS can be polished, pigmented, water based
and acid stained. RS
is trowelable, sprayable and
castable. RS can also be used for, but not limited
to: concrete resurfacing, patching and repairs, one coat stucco repair,
pre-cast, block & brick, anchoring/doweling concrete,
footers/foundations, caissons/piers,
flooring, etc.
Mixing
Add
3 quarts of potable water per 50-lb bag. Mix by mechanical means for 3 minutes.
Additional water may be added depending on application, desired consistency,
humidity and relative site conditions. Less water will result in higher
strengths. Do
not exceed 5 quarts of water. Mix
only enough material to place within 20 minutes. Larger quantities can be mixed if
pressurized spray or pump equipment is used. Set times can be extended by
additives and custom blends, please contact Cerako USA for further information.
Aggregates Up to 100% by weight can be added depending on application.
Application
RS is
a professional grade material that should only be installed by recommended and
licensed contractors or those with extensive concrete/cement experience. RS can be applied from ½”-6” thick. Thicker
applications can be achieved with the use of additional aggregate. Substrate to
be repaired must be free of dust, dirt, oil, paint or any foreign materials. Surface can be wet
prior to repair. Pour in layers across repair area to desired finish height.
After initial set RS
can be brushed, textured or hard
troweled to desired finish. Follow
standard cement-based
practices dependent on desired
application and finish broadcasting
fine aggregate into surface prior to initial set can be used to provide a
non-slip surface. Please
contact Cerako USA for further information.
Spraying
Set
spray equipment to 8-15 psi, a large nozzle size is recommended or size to
desired finish. It is recommended to spray a test area prior to final
application. Build to at least 1/8” thick in multiple passes. Applying material
too thick at one time may result in sagging. RS is
only to be installed by Cerako USA recommended contractor or someone with extensive masonry and/or concrete experience.
