MORTAR MIX High-Strength Structural Repair Mortar
CURING: Water cure all Rapid Set
®
MORTAR MIX installations by keeping exposed surfaces
wet for a minimum of 1 hour. Begin curing as soon as the surface starts to lose its moist
sheen. When experiencing extended setting time due to cold temperature or the use of
retarder, longer curing times may be required. The objective of water curing shall be to
maintain a continuously wet surface until the product has achieved sufcient strength.
COLD WEATHER: Environmental and material temperatures below 70°F (21°C) may delay
setting time and reduce the rate of strength gain. Lower temperatures will have a more
pronounced effect. Thinner sections will be more signicantly affected. To compensate
for cold temperatures, keep material warm, use heated mix water, and follow ACI 306
Procedures for Cold Weather Concreting.
WARM WEATHER: Environmental and material temperatures above 70°F (21°C) may
speed setting time and increase the rate of strength gain. Higher temperatures will have
a more pronounced effect. To compensate for warm temperatures, keep material cool,
use chilled mix water, and follow ACI 305 Procedures for Hot Weather Concreting. The use
of Rapid Set

will help offset the effects of high temperatures.
YIELD & PACKAGING: MORTAR MIX is available in 55-lb and 25-lb (25-kg and 11.3-kg)
sizes. One 55-lb (25-kg) bag of MORTAR MIX will yield approximately 0.5 ft

WARNING: DO NOT BREATHE DUST. AVOID CONTACT WITH SKIN AND EYES. Use
material in well-ventilated areas only. Exposure to cement dust may irritate eyes, nose,
throat, and the upper respiratory system/lungs. Silica exposure by inhalation may result
in the development of lung injuries and pulmonary diseases, including silicosis and lung
cancer. Seek medical treatment if you experience difculty breathing while using this
product. The use of a NIOSH/MSHA-approved respirator (P-, N- or R-95) is recommended
to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid
ingesting cement dust. Skin contact with dry material or wet mixtures may result in
bodily injury ranging from moderate irritation and thickening/cracking of skin to severe
skin damage from chemical burns. If irritation or burning occurs, seek medical treatment.
Protect eyes with goggles or safety glasses with side shields. Cover skin with protective
clothing. Use chemical resistant gloves and waterproof boots. In case of skin contact
with cement dust, immediately wash off dust with soap and water to avoid skin damage.
In case of skin contact with wet concrete, wash exposed skin areas with cold running
water as soon as possible. In case of eye contact with cement dust, ush immediately
and repeatedly with clean water, and consult a physician. If wet concrete splashes into
eyes, rinse eyes with clean water for at least 15 minutes and go to the hospital for
further treatment.
