Speedcrete Redline Bag: Euclid Speedcrete 50Ib

Speedcrete Redline Bag is a rapid-setting, cement-based concrete and masonry repair mortar. Speed Crete Red Line Bag is a proprietary formulation of blended portland cements, finely processed selected aggregates, and
specific chemical additives that undergo a chemical “hyper hydration” and produces a stable, low permeability,
cementitious matrix. Speedcrete Redline Bag can be “shaved” for detailed repairs. Questions? Contact Us.

Surface Preparation: Concrete surfaces must be structurally sound, free of loose or deteriorated concrete and free of dust, dirt, paint, efflorescence, oil and all other contaminants. Mechanically abrade the surface to achieve a surface profile equal to CSP 6 – 8 in accordance with ICRI Guideline 310.2. Properly clean profiled area.

Priming & Bonding (Saw Cut & Chipped Out Repairs): Thoroughly clean any exposed reinforcing steel, and apply DURALPREP A.C. to the concrete and the reinforcing steel within the repair area. Refer to the DURALPREP A.C. technical data sheet for full instructions. Alternatively, application of EUCOWELD 2.0 or a scrub coat of SPEED CRETE RED LINE to the saturated surface dry (SSD) concrete surface may be used for bonding. The repair material must be placed on the scrub coat before the scrub coat dries out.

Mixing: SPEED CRETE  will require approximately 5 to 5.5 qt (4.7 to 5.2 L) of potable water per 50 lb
(22.7 kg) bag to achieve the proper mix consistency. Pour the measured amount of water into a clean mixing
container, then add the SPEED CRETE , and thoroughly mix for no more than 60 seconds to a stiff,
no slump, putty-like consistency. Mix small quantities of SPEED CRETE in a clean pail with a hand
trowel. Use a rotary mixer with rubber tip blades for mixing quantities up to 100 lbs. (45.4 kg). To fill patches 2”
(5.1 cm) deep or greater, add clean, pre-dampened, 3/8” (0.96 cm) size pea gravel. DO NOT USE LIMESTONE
AGGREGATE. The mix ratio must not exceed 40 lbs. (18 kg) of pea gravel to each 50 lb (22.7 kg) bag or pail of
SPEED CRETE . Mixing procedure: Start mixer, load water, load pea gravel, and then load the SPEED
CRETE RED LINE. MIX FOR NO MORE THAN 60 SECONDS.

Application: For vertical repairs, place SPEED CRETE RED LINE in 1/8” – 2” (3.2mm – 50.0 mm) lifts. To ensure
a complete bond with the entire surface, force the SPEED CRETE RED LINE firmly into the SSD area by hand or
with a trowel. Slightly overfill the repair, and following initial set, shave the material to conform to the contour of
the surrounding surface. Always shave SPEED CRETE RED LINE toward the common bonding edge between
the repair mortar and the existing surface. Cure material using standard curing practices.

Cold Weather Installation: Application at temperatures below 40°F (4°C) extends the set time. Heating the repair area until warm, using warm water for mixing, and tenting/insulating the repair area after application will increase strength development. Do not use direct heat on the repair after it is installed.
