Instructions / Assembly

Thickness of Installation
HENRY 615 can be installed from 1/4” to 1/2” (6 to 12 mm)
neat, and up to 2” (5 cm) with the addition of proper aggregate.
For areas thicker than 1/2” (12 mm), mix HENRY 615 with
washed and well-graded 1/8”-1/4” (3 to 6 mm) pea gravel. Mix
the HENRY 615 with water first, and then add 1 part by volume
of aggregate, mixing until the aggregate is completely coated.
Do not use sand. If aggregate is wet, reduce the amount of
water to avoid over watering. Please note that thicker areas will
take longer to set and will reduce the overall coverage.
Curing
Although HENRY 615 requires no special curing procedures,
avoid applying this product if rain is expected within 6 to 8
hours, or if freezing temperatures could occur within 24 hours
of application. As with any cementitious material, the above
conditions can alter the appearance and performance of the
patching compound. HENRY 615 can receive light foot traffic
after approximately 2 hours.
Color
HENRY 615 is formulated from Portland cement and is a light
gray color when dry. As concrete color and jobsite conditions
vary widely, it is not intended that this product will match the
color of the concrete being resurfaced or an adjacent concrete
pad. Jobsite conditions such as direct sunlight and wind, as well
as the surface of the HENRY 615 being exposed to moisture
before it completely sets, can lead to minor color variations in
the appearance of the patching compound.
If a more uniform aesthetic appearance is desired, HENRY
recommends that the repaired area and adjacent concrete either
be skim coated with HENRY 625 or HENRY 625F after 4 hours,
or sealed with HENRY 635 in Gray after 24 hours. Please refer
to the HENRY Technical Brochures for instructions.
Sealing
As is the case with any concrete surface, HENRY 615 should
be sealed with a water-borne, breathable concrete sealer to
prevent dusting and to help resist damage from standing water,
salt or oil, as well as staining and marking. HENRY recommends
the use of HENRY 635 to seal HENRY 615, as well as other
absorbent concrete and masonry surfaces. Sealing can proceed
once the HENRY 615 has cured for a minimum of 24 hours
(70°F/21°C). If HENRY 625 or HENRY 625F is installed over the
HENRY 615, the installation still requires a minimum of 24 hours
before sealing. Avoid full traffic and vehicular traffic until the
sealer has dried thoroughly. For further information, please refer
to the HENRY Technical Brochures.
Notes
The pot life of HENRY 615 is approximately 30 minutes at 70°F
(21°C). Pot life will vary with ambient temperatures.
HENRY 615 is intended for resurfacing interior and exterior
concrete subject to foot and rubber-wheeled traffic. Do not use
in fountains, inside swimming pools or in any areas that will be
permanently submerged in water.
HENRY 615 is recommended for residential and commercial
use only. HENRY 615 is not intended for industrial uses such
as heavy manufacturing or areas with heavy truck traffic.
Always install an adequate number of properly located test
areas, including the sealer, to determine the suitability and
aesthetic value of the products for the intended use. As sealers
vary, always contact and rely upon the sealer manufacturer
for specific directives such as maximum allowable moisture
content, sealer selection and intended end use of the product.
Never mix with cement or additives other than HENRY
approved products. Observe the basic rules of concrete work.
Do not install below 50°F (10°C) surface and air temperatures.
Install quickly if substrate is warm, and follow warm weather
instructions available from the HENRY Technical Service
Department.
