Coverage Rates for NanoPave JSS ( Joint Stabilizer & Sealer)
Coverage rate is dependent on paver or stone porosity,
joint width, depth and the type of jointing material used.
See Section lV for more information on jointing material
Joint Width: Recommended Joint Material: NP-JSS JSS® Coverage:
1/4"-1/2" (6.35 mm-1.25 cm) Masonry Sand 75-100ft2/gal (1.45-1.95 m2/ litre)
1/2”-3/4” (1.25-1.9 cm) Playground Sand 60-75ft2/gal (1.1-1.45 m2/ litre)
3/4”-4” (1.9-10 cm) Crushed Stone Mix or 30-60ft2/gal (.73-1.1 m2/ litre)
Decomposed Granite (DG)
Push broom / leaf blower
• Pressurized sprayer (25-40 psi/ 1.7-2.75 bar)
• Foam rubber squeegee
• Vibratory plate compactor (A rubber sole
may be needed for some surfaces)
• Hand tamp and/or rubber mallet
Suitable Applications / Materials
For joints ranging from 1/8” to 3/4” (3.2 mm-.1.9 cm) in width, use standard masonry or playground sand.
For joints ranging from 3/4” up to 4” (1.9-10 cm), use a crushed stone
mix or decomposed granite (DG) material preferably with a
gradation range of either 1/4” minus or 3/8” (6.4-9.5 mm) minus.
Avoid jointing materials that contain clay, dirt, or materials
that lack structural integrity. Screened aggregates that
may improve permeability will not stabilize well.
Top 5 Tips for NanoPave JSS ( Joint Stabilizer & Sealer)
ALWAYS PERFORM A TEST SECTION TO CONFIRM
SUITABILITY OF MATERIALS & PROJECT CONDITIONS!
NP-JSS should be installed within an ambient and
surface temperature range of 40°-90° F (4.4-32.2 C). Shaded,
low sunlight, or colder areas will lengthen cure times.
Conversely, direct sun, warmer areas will shorten cure
times. Avoid temperatures at or below freezing or
above 100° F (0 and 38 C) for NP-JSS curing phase or storage.
NP-JSS is a water-based formulation. The curing phase
is dependent upon complete evaporation of the water
component (usually 12-48 hours in optimal conditions).
NP-JSS may be installed on moderately damp surfaces
and jointing materials, including wet paver joint sand
applications (wider joint applications may vary).
Do not install NP-JSS within 24-48 hours before or after
rainfall. In excessively wet conditions, allow to dry before
Do not divide recommended application rates into
multiple coats. Always consult manufacturer coverage
rate guidelines, or contact TechniSoil technical support
Consider complimentary weather conditions before,
during, and after any NP-JSS application.
NP-JSS may be installed on damp surfaces and jointing
materials, including wet joint sand applications. Avoid excessively wet conditions or standing water. Do not install
NP-JSS within 24-48 hours before or after rainfall. in excessively wet conditions, allow materials and project area
NP-JSS should be installed within an ambient and surface temperature range of 40-90˚F (4.4-32.2 C). Shaded, low sunlight, or colder areas will lengthen cure times; conversely,
direct sun, warmer areas will shorten cure times.
NOTE: Ambient and surface temperatures are typically not the same. Be sure to check both individually
prior to NP-JSS application.
Installation of NanoPave JSS ( Joint Stabilizer & Sealer)
Apply recommended jointing material to surface
• Sweep jointing material thoroughly into all
pavement joints using a push broom. A whisk
broom may be used in tight or hard to reach
• For brittle paving materials, use a padded hand
tamp or rubber mallet to tamp the surface to fill
any air pockets and settle the jointing material
between the stone joints. Repeat as necessary
until joints are properly filled with jointing material.
• For sturdy paving materials use a vibratory
plate compactor (rubber sole) to settle sand
between the paver joints. Repeat as necessary
until joints are properly filled with sand.
For best results, thoroughly remove any residual sand,
dust or aggregates from the surface using a leaf blower or
broom before applying NP-JSS.
NP-JSS is easily applied using a standard 1-5 gallon (3.8-19 litre)
capacity low-pressure, pump sprayer. For larger
applications, electric, high-capacity sprayer may be used.
Mask or shield any adjacent surfaces in case of overspray or accidental application.
Apply NP-JSS to the paving surface using pressurized
spray equipment (40 psi/ 2.75 bar maximum). Concentrate primarily
on the joints between the paving material, and evenly
apply NP-JSS using the rate recommended in Section IV.
Do not divide recommended application rates into multiple
coats. Always consult manufacturer coverage rate
guidelines or contact technical support at: 877-356-2250.
Use a foam rubber squeegee or equivalent to remove
excess or standing NP-JSS from the surface of the
pavement. Evenly distribute excess liquid into adjacent
Keep project area free from any moisture such as rain or
irrigation sprinklers, unnecessary foot traffic or otherwise
on treated areas until fully cured. (usually 12-48 hours in
Cure Times for NanoPave JSS ( Joint Stabilizer & Sealer)
12-48 hours in
Clean all tools immediately after use by simply rinsing
tools with water and a soft bristle brush.
Storage of NanoPave JSS ( Joint Stabilizer & Sealer)
Store NP-JSS out of direct sunlight in areas with a
temperature range of 40º-90º F (4.4-32.2 C)
Treated areas should withstand normal conditions for
24-48 months before a maintenance coat is needed.
• In high traffic settings and/or in inclement
weather conditions, an increased maintenance
schedule may be required.
If jointing material is in satisfactory condition and only
a sealer maintenance coat is needed, apply NP-JSS at
twice the original application rate.
To repair degradation that occurs in existing joints:
• Scarify exposed joint areas and fill with
additional sand or crushed stone mix.
Use a padded hand tamp or rubber mallet to
completely fill joint as needed.
• Apply NP-JSS to the new material with a
pressurized sprayer and saturate until the joint
is milky white.
• Remove excess NP-JSS with a foam rubber
squeegee. In normal conditions, the repaired
area should be cured within 12-48 hours.
