VERY RAPID-SETTING HORIZONTAL REPAIR MORTAR
SEALTIGHT FUTURA-15 is a one component,
cementitious, very rapid-hardening structural repair mortar designed for
horizontal applications. FUTURA-15 is composed of selected cements, graded sands
and chemical additives. This proprietary blend produces a very rapid-setting
structural repair mortar even in cold weather conditions without the aid of
chloride or gypsum based accelerators.
SEALTIGHT FUTURA-15 is ideal for structural patching of concrete
pavements, bridges, parking decks, airport runways and taxiways. FUTURA-15 is
also designed for repair of industrial floors, expansion joint nosings,
sidewalks and general commercial applications, along with grouting keyways.

Yields listed above are based on 4.75 pints (2.25L) of
water per 50-lb. bag and will vary based on substrate profile, mix ratios,
aggregate type and waste. Field trials should be performed to determine yields
based on aggregate type.

FOR BEST PERFORMANCE
|FUTURA-15 is recommended for concrete repairs only
|Do not use as an underlayment or overlay
|Protect from freezing for a minimum of 24 hours.
|Do not bridge moving cracks. Extend existing control
and expansion joints through FUTURA-15.
|For large areas with no control, expansion or
construction joints, refer to ACI Guidelines.
|Do not exceed a length-to-width ratio of 2 to 1 for the

|Exceeding liquid requirements shall result in reduced
|Realize that set time will decrease as the product,
air, substrate and mixing liquid temperature increases and will increase as
the temperature decreases.
|Repair areas should be saw cut and slightly undercut to
a minimum depth of a 1/2" (12.5 mm). Do not featheredge.
|Protect from conditions that may cause early water
loss; windy, low humidity, high temperature and direct sunlight. Early water
loss is exasperated in thin applications.
|Realize that the use of extender aggregate will alter
|Do not use evaporation retardants, such as SEALTIGHT
EVAPRE with this product.
|Failure to follow industry standard practices may
result in decreased material performance.
|Proper application is the responsibility of the user.

Perform surface preparation in accordance
with ICRI Technical Guidelines No. 03730, "Guide for Surface Preparation
for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel
Corrosion." Mechanically abrade existing substrate to remove all unsound
concrete, but do not use excessive force, which may cause micro-fracturing.
Substrate must be structurally sound and free of any contaminants that will
adversely affect the bond. Prepared substrate surface must have a sufficient
profile of ¼" to ensure adequate mechanical lock. Saw cut perimeter of
repair zone to a depth of ½" to avoid feather edging.
Completely expose all reinforcing steel, ensuring a
minimum clearance of ¾" behind reinforcing steel. Abrade entire
circumference of steel to a white metal finish. Perform reinforcing steel
preparation in accordance with ICRI Technical Guidelines No. 03730. Pre-dampen
concrete substrate to a saturated surface dry (SSD) condition. Remove all
standing water and puddles.
Mix only complete bags. Using a suitable sized mortar type mixer, add 4.75-5.25
pints (2.24-2.48L) of clean water to the mixer per 50 lbs. (22.7 kg) bag of
FUTURA-15. If extension is required, add appropriate amount of aggregate to
mixer prior to the addition of FUTURA-15. Mix for 3-5 minutes until homogenous
and lump-free. Do not mix more product than can be mixed, placed and finished in
15 minutes at 70° F (21° C). Do not over-mix.
For repairs greater than 2" (51mm) in depth; extend FUTURA-15 with 12.5
lbs. (5.68 kg) of aggregate. For repairs greater than 4" (102 mm) in depth
extend FUTURA-15 with 25 lbs. (11.36 kg) of aggregate. The aggregate must be a
minimum of 3/8" (9mm) size, saturated but surface dry condition, clean pea
gravel. Always add the aggregate to the mixing water prior to the addition of
FUTURA-15. For configurations requiring greater than 50% extension or larger
areas, contact your local W.R. MEADOWS representative. Proper stress relief must
be given for large patch areas.
Apply FUTURA-15 by trowel or screed. Compact FUTURA-15 well against the prepared
substrate prior to bulk placement. Ensure complete encapsulation of reinforcing
steel. Finish surface by screeding FUTURA-15 to a level surface. For a rough
finish, a broom or burlap bag is suitable, never re-temper. Do not re-temper or
Follow ACI 305-R89 "Standard on Hot Weather
Concreting" or ACI 306-R88 "Standard on Cold Weather Concreting,"
May be top-coated with an epoxy-based overlay after 4
hours. For all other systems, wait a minimum of 24 hours prior to topcoating.
Consult appropriate installation guide for the product to be overlaid.
FUTURA-15 must be immediately cured in accordance with ACI 308. If a membrane
curing compound is used, we suggest using SEALTIGHT 2250-WHITE or SEALTIGHT
1130-CLEAR. On large patches, cure repair zone as work proceeds. Wet curing for
a minimum of one day, followed by a suitable curing compound helps minimize
