INSTANT PATCHING CEMENT
Page 2
Mixing
1. Use cool, potable water, clean tools and clean containers.
For additional bond strength to the substrate, use a concrete
bonding additive in place of water.
2. Mix only the amount that can be applied within the 10-20
minute working time.
3. Add approximately 1½ pints (.71 L) of clean, cool water per
10 lbs. (4.5 kg) of powder. (Ratio of approximately 2.4 oz.
liquid per 1 lb. powder.) Always add powder to liquid to avoid
lumps. Avoid high-speed mechanical mixing which can
entrap air into the mixture. Smaller amounts can be mixed by
hand. When mixing partial bags, it is a good practice to dry
blend the powder in case of settling during shipment.
4. Mix to a uniform, lump-free, putty-like consistency,
approximately 2-3 minutes.
5. Warmer temperatures will reduce the working time. The
addition of cold water at high temperatures, or warm water in
low temperatures will aid in adjusting the mix temperature.
6. For repairs over 1 in. (2.5 cm) thick, add 5 lbs. (2.26 kg) of
dry 3/8” pea gravel per 10 lbs. of Instant Patching Cement.
Apply pea gravel blend up to 5 in. (127 mm) per layer.
Application
1. Apply using a steel trowel to surfaces that are frost free and
above 40°F (4°C) and below 90°F (32°C) within 24 hours of
application and 48 hours thereafter. Do not apply in direct
sunlight on hot, windy days, or when rain is forecast to fall on
the surface within 6-8 hours.
2. To reduce shrinkage and cracking, build up in layers of 1 in.
(25 mm) neat, or 5 in. (127 mm) when extended. Additional
layers can be applied after 24 hours.
3. Clean the surface of the trowel often with water and use a
“light touch” when finishing the surface. Do not over trowel. If
a textured finish is desired, brush in one direction with a soft-
bristled brush or broom while patch is still soft.
4. Protect the surface from use until patch is completely hard
and set. On average, supports foot traffic in 5 hours, wheeled
traffic in 24 hours depending upon temperatures and
humidity.
Curing
After the patch has reached final set, during the first 24 hours,
keep the patch damp or covered to prevent excessive loss of
water, especially during hot and/or drying winds or when low
humidity are present. Under such conditions, damp cure by
covering the surface with wet burlap or towel overnight to retain
moisture or lightly fog spray. Note, color may be affected where
covering comes in contact with the new patch. After 24 hours,
remove covering and allow to air cure. Damp curing is not
required when used to repair smaller cracks.
Repair can be painted with a latex masonry paint once cured a
minimum of 7 days and area remains dry.
Clean Up
Use soapy water to clean hands and tools immediately after
use. Dried material must be mechanically removed. Use a
waste water hardener (e.g. Congelz™ or similar product) for
cementitious waste disposal.
Limitations
• Follow all industry standard safety procedures when
handling, such as gloves and eye protection. Wear gloves at
all times, failure to do so can result in severe burns.
• Use only clean mixing containers and tools.
• Do not use more than the recommended amount of liquid.
Overwatering may cause excessive shrinkage and cracking.
• Do not cover or fill expansion or control joints.
• Do not apply over concrete cured less than 28 days, or is
frozen or contains frost.
