BOND COAT
Mixing
Add four (4) quarts of water to an empty, clean 5 gal. container.
Slowly introduce one (1) 50 lb. bag of Bond Coat/Spray Texture
Bag Mix (TX-SC) while mixing with an adequate drill equipped
with a cage type mixer. A 450 rpm drill speed is recommended.
Mix thoroughly for at least one (1) minute paying close attention
to potential dry material on sides or bottom of bucket. Additional
bag mix may be required to achieve desired consistency.
NOTE: The amount of water required may vary slightly due
to temperature and humidity. i.e. cool temperatures and/or
high humidity requires less liquid solution for equal workability.
Also, smaller jobs may only require mixing partial bags of
bond coat.
Application
Cover or mask all areas requiring protection with tape and
paper so the material does not bond to unwanted surfaces.
Dampen concrete before applying bond coat. Concrete MUST be
damp with no standing water prior to bond coat application.
Pour mixed material onto the existing damp slab and trowel
to approximately 1/16" or 1/8" thickness. This will
fill in any slight inconsistencies in the concrete surface
and leave a flat, even base that is essential for a successful
application.
NOTE: Bond coat coverage rates for texture are generally less
than bond coat coverage rates for a stamped overlay. Stamp
mix material will fill small inconsistencies in the surface.
Texture coat must be applied slightly thicker and much smoother
than that of stamp bond coat to help hide surface inconsistencies.
After the bond coat is dry, (this should occur within two
hours depending on climate) rub down any high spots or trowel
marks with a brick or shave using a trowel. Broom and blow
off surface to remove loose material.
SPRAY TEXTURE
Mixing
Add four (4) quarts of water to an empty, clean 5 gal. container.
Slowly introduce one (1) 50 lb. bag of Bond Coat/Spray Texture
Bag Mix (TX-SC) while mixing with an adequate drill equipped
with a cage type mixer. A 450 rpm drill speed is recommended.
Mix thoroughly for at least one (1) minute paying close attention
to potential dry material on sides or bottom of bucket. Lumpy
material will not shoot well through the hopper gun and will
result in an uneven texture. Adjust the consistency with additional
water (up to one quart per bag) as needed to suit personal
techniques.
Application
Cover or mask all areas requiring protection with tape and
paper so that material does not bond to unwanted surfaces.
Carefully place stencils or tape as required. Do not dampen
bond coat prior to shooting texture.
Read and understand all operating instructions for hopper
gun and air compressor prior to starting project. Adjust air
pressure typically between 8 and 15 psi and set hopper gun
orifice to desired size. Fill hopper approximately 80% and
hold 36 to 48 inches above surface. Shoot texture evenly over
surface in small circular or figure 8 patterns achieving the
desired coverage. Use care not to disturb stencils while walking
or stepping backwards.
The newly shot material will have a glossy or wet appearance.
After this gloss has become matte or dull, the material is
ready for troweling. This time (usually 1 to 5 min.) will
vary depending on temperature and humidity. Wearing metal-cleat
golf shoes or spikes, walk out to the area ready to trowel.
Using a round-corner trowel, lightly test an area to establish
the force required for the
desired texture. Once the required force is established,
maintain this pressure while troweling in a large arching
motion. Wipe trowel after each pass with a damp rag to ensure
a clean texture.
After the texture coat has dried, (usually the following
day) tape and stencils may be pulled. After lifting tape,
stencils, and any masking, remove rough points or edges with
a trowel by scraping it across the surface. Use a blower to
remove loose material.
SEALER
Two coats of clear or pigmented sealer are required to complete
the project. The surface must be clean, completely dry and
at least 40° F during the sealer application. Open the
pail of sealer and mix thoroughly with drill. To apply with
roller, use a solvent resistant, ½" nap. Apply
one thin coat forcing the sealer into the low areas of the
texture. Allow sealer to dry then repeat the process with
a coat of non-skid modified sealer. To apply with an airless
sprayer, use a size 8/13 reversible tip and spray evenly onto
the concrete surface. Allow first coat to dry completely and
apply the second non-skid modified coat in the same manner.
CURE TIME
Allow twenty-four (24) hours before permitting foot traffic
on sealed area. Allow seventy-two (72) hours before permitting
vehicle traffic on sealed area.
CLEAN UP
Equipment and tools should be cleaned immediately after use.
Water may be used to clean polymer-modified cement from tools.
Solvent may be used to clean up sealer.
