GENERAL INFORMATION
NanoPave JSS (NP-JSS) is a revolutionary 2-in-1 joint stabilizer and sealer product for use with pavers, natural stone, and flagstone. NP-JSS creates a strong, durable bond in common sand or crushed stone jointing materials for joints up to 4” wide. NP-JSS is also a UV resistant, VOC-free sealant that protects and helps maintain the natural beauty of most paving surfaces.
Advanced Formula NanoPave JSS is an industry leading, water-based, VOC-free, liquid nano-polymer stabilizer. Common jointing materials such as masonry sand in joints less than ¾” or crushed stone mixes in joints up to 4” are bonded by topically applying to most hardscape surfaces. Stable joint materials improves surface stability, and also reduces erosion, insect infestations, and weeds.
NanoPave JSS is also a fast curing, long-lasting sealer with ultra-high clarity that can be applied in a surface and ambient temperature range of 40º – 90ºF. It is suitable for application to dry or damp surfaces, which is ideal for new installations or restoration of existing hardscape projects. NP-JSS is available in two breathable sheens; Natural Look Finish – Ghost; Enhanced Look Finish – Gloss-
PROJECT PLANNING:
Before starting a project what should be done to ensure best results?
- Calculate the square footage of the project area to determine the required amount of NanoPave JSS and other material quantities needed.
- Consider hardscape joint width and select a suitable, complementary jointing material (i.e. for wider joints use a crushed stone mix such as decomposed granite).
- Check ambient and surface temperatures for application areas to ensure a suitable range for both installation and the curing process.
- Pause irrigation sprinklers and check weather forecast for any precipitation within 72 hours of applying NanoPave JSS.
- Perform a small test section to determine suitability of materials.

EXPECTATIONS:
What should I expect from a surface treated with NanoPave JSS?
NanoPave JSS is a 2-in-1 liquid polymer joint stabilizer and UV-resistant sealant solution for a wide range of hardscape surfacing products. The fast curing, ultra clear sealer component enhances the natural colors of pavers, bricks, flagstone, and natural stone while also helping to prevent staining and fading. Stabilizing joint material will reduce erosion, weed and insect infestation, and the displacement of hardscape materials.
Why is NanoPave JSS better than other options?
Non-stabilized joint material needs to be constantly maintained and re-applied. Polymeric sand products often create staining or hazing to the paving surface and may have inconsistent stabilization. Competing liquid stabilizers are not compatible with joint widths of 1” or more. NanoPave JSS can be used in any joint from ?” up to 4” depending only on the joint material used.
What is nano-polymer technology and why does it make NanoPave JSS a better choice?
NanoPave JSS was developed for optimum joint material absorption and a bond that offers durability, strength and flexibility. Nano-polymers are small and consistent, which allows for a smooth seal to the paving surface and a deeper absorption into the jointing material.-
COMMON USES:
What are the most common projects to use NanoPave JSS on?
NanoPave JSS is most commonly used on hardscape walkways and patios constructed with pavers, bricks, flagstone, and natural stone in both residential and commercial application projects.
Can NanoPave JSS be used on a driveway?
Yes, but there are some variables to consider before application. Auto and truck tire compositions can vary dramatically, some of which are more prone to tracking on certain surfaces. If the driveway is currently prone to tracking, it isn’t recommended apply NanoPave JSS before performing a test section. Also, roughly textured pavers or stone can often times be more prone to tire tracking because of the extreme point load taken on by small elevated areas of the stone. And finally, application rates and temperature ranges play a pivotal role. Splitting application coats, under-applying, failing to remove excess liquid from the surface or applying when the temperature ranges to too hot can adversely affect the outcome, especially in driveway projects.
Can NanoPave JSS be used as a stand-alone sealer?
NanoPave JSS is specifically formulated with a nano-polymer blend that provides stabilization of jointing materials while adding a protective sealant coat to the hardscape surface. If joint stabilization is not needed for an existing project, we recommend using NanoPave Hardscape Sealer to take advantage of the nano-polymer sealant qualities.-
TOOLS:
What tools are required to prepare the surface and apply NanoPave JSS?
Shovel, push broom, pressurized sprayer (25-40 psi), foam rubber squeegee, grout sponge, vibratory plate compactor (with rubber sole if needed), hand tamper, plastic to cover surrounding areas from accidental spills or overspray.
What is the best tool for NanoPave JSS application?
A pressurized sprayer (garden, pump or backpack are recommended). Do not use a watering can or roll on the material.-
JOINT MATERIAL SELECTION:
What type of sand works best with NanoPave JSS?
For premium aesthetic and complimentary use, UltraMix Designer Series Paver Joint Sand is strongly recommended. A standard jointing sand or all-purpose masonry sand is also suitable for paver or brick joints ranging from ?” to ¾” in width.
Can I use a washed or hourglass sand with NanoPave JSS?
It is not recommended, washed sands tend to abrade easily from the surface.
How do I prepare the paving joints before applying NanoPave JSS?
Sweep sand into the paver joints using a push broom, then use a vibratory plate compactor (rubber sole) to settle sand between the paver joints. This may need to be repeated to assure the joints are properly filled with sand. Using a push broom and a leaf blower clean any loose sand or impediments of the paver surface. Any residue that is not removed will be sealed onto the pavers, so make sure the surface is completely clean before applying NanoPave JSS.
What are some recommended materials for joint sand?
First and foremost, we recommend the use of UltraMix Designer Series Paver Joint Sand for all hardscape joints up to a maximum of ¾” in width. Otherwise, an all-purpose or masonry sand works well with NanoPave JSS for joints up to ¾” in width. Do not use an ultra fine sand or screened sands as they may not bind well. Decomposed granite (DG) or crushed stone mixes are recommended for joints ranging from ¾” up to 4” in width.-
PAVERS, BRICKS, & SMALL JOINT HARDSCAPE SURFACES:
What are the most common small joint project applications for NanoPave JSS?
Manufactured hardscape surface stones such as pavers and bricks are most common. Pavers are often referred to as interlocking pavers or simply interlocks as well. Paver stones are usually manufactured from clay or concrete and come available in a nearly endless array of colors and sizes. The pavers will often have bumpers on the sides to allow for equidistant joint spacing, commonly no more than ¼”.
What is the purpose of a hardscape joint?
A sand paver joint literally provides a cushion for the stones to allow for shift or movement. When a rigid stone is hard set next to others, the force from a point load or ground shift can cause the stones to crack or break completely. With a joint between, similar to expansion joints in concrete flatwork, the stones have leeway to prevent damage.
What is the benefit of using NanoPave JSS over a traditional polymeric sand?
Polymeric sands have long been the standard in hardscape. They are sands that contain a water activated, powdered polymer (often Portland cement powder). While easy to use, polymeric sands can present a few undesirable problems. These would including hazing of the hardscape surface upon water activation; inconsistent stabilization; and harmful, dusty installation steps. NanoPave JSS virtually eliminates all of those issues by stabilizing a common sand and offering an enhancing sealant to the paver stones.
Why is it better to use UltraMix Paver Joint Sand with NanoPave JSS in small joints?
UltraMix Designer Series Paver Joint Sand products broke the long standing tradition of plain color joint sands for pavers. Manufactured pavers are often expensive yet beautiful and come in an endless array of colors and color blends. Installing a traditional grey or tan polymeric sand with mismatched paver colors can significantly reduce the aesthetic. UltraMix features as many as 18 colors and color blends, all processed to a premium gradation of sand that is perfectly suited for joint widths from ?” up to ¾” and offers a dust free installation. Better yet, UltraMix was specifically designed to work hand in hand with the stabilizing and sealing qualities of NanoPave JSS.
How come sand is not recommended for use in larger joints over ¾” in width?
Because sand is too fine of a material to stand up well on its own spanning that a gap of that size. Joints of 1” or larger will often be required to handle a point load from something like a patio chair leg, BBQ wheel or leg, or a high heel shoe. Common sand will disperse underneath these types of point loads, often times, even when stabilized. It is recommended to use a crushed stone material like decomposed granite (DG) because these materials are much stronger and rigid.-
FLAGSTONE, NATURAL STONE, & LARGE JOINT HARDSCAPE SURFACES:
What material is recommended for use with NanoPave JSS on wide joints ( ¾” and wider)?
A ¼” minus or ?” minus crushed aggregate mix, such as decomposed granite (DG), is recommended when using NanoPave JSS on wider joints.
Can sand or screened aggregates be used as a jointing material in wide joints?
No. Sand will easily abrade away in wider joints. NanoPave JSS requires a blend of aggregate chips and stone dust, so screened aggregates such as pea gravel will not work.
How do I add the crushed stone mixture to the paving joints?
Sweep crushed stone mixture into the paver joints using a push broom. Use a rubber mallet to tap the edges of the surface stones, this will fill any air pockets and settle the material between the stone joints. This process may need to be repeated to assure the joints are properly filled with. Using a push broom and a leaf blower, clean any loose aggregates and stone dust off the paver surface. Any residue that is not removed will be sealed onto the pavers, so make sure the surface is completely clean before applying NanoPave JSS.
Why is sand not recommended for joints larger than ¾”?
Sand is small granules and uniform in size, making it more likely to wear away compared to a traditional ¼” minus or ?” minus crushed stone material. These materials are processed to contain a proportion of smaller to larger aggregates which will create a more dense and durable surface rigidity.-
NP-JSS APPLICATION:
How is NanoPave JSS applied?
Using a pressurized sprayer, apply NanoPave JSS at the recommended rates based on your paver joint width. Evenly apply NanoPave JSS over the paver surface, the wider the joints the more NanoPave JSS will need to be applied. After applying NanoPave JSS at the recommended coverage rate, evenly distribute any residual NanoPave JSS that hasn’t absorbed into the pavers or joints after 10 minutes using a foam rubber squeegee to push/pull the excess liquid into the joints. Use a grout sponge to remove any additional material if needed.
Can I apply multiple coats of NanoPave JSS?
It is not recommended because NanoPave JSS was designed as a single 2-in-1 application process. Our nano-polymer technology creates an even, solid seal to the paving surface and stabilizes jointing material. Dividing applications coasts or adding extra coats of NanoPave JSS is unnecessary, and in turn, can create other issues such as stacking, flashing or modified surface aesthetic and sheen.
How long does it take for NanoPave JSS to cure?
In optimal conditions the surface will cure in 24 – 48 hours. Humidity, temperature and atmospheric conditions can cause the curing time windows to fluctuate. NanoPave JSS is a water-based product and the curing process is based on evaporation of the water component. Once your NanoPave JSS treated joint material is dry and hard to the touch, it is cured. If the material is still wet or soft, allow for the joint material to fully dry and harden until completely cured.
How soon can I apply NanoPave JSS before and after a rain event?
It is not recommended to apply NanoPave JSS 48 – 72 hours before or after a heavy rain event. Light rains are not usually an issue, but heavy or prolonged rains before or after applying NanoPave JSS should be avoided. If the joint material is saturated it dilute the stabilizing polymer component in NanoPave JSS which can compromise the installation. If rain is forecast within 72 hours it is recommended to wait for dryer conditions. This is even more important in cool, shaded and overcast conditions, since this will affect evaporation and slow the curing process.
What should I do if it rains before NanoPave JSS has cured?
If rain is forecast before the surface has cured, it is recommended to tarp the treated area with plastic. If possible, keep the tarp suspended above the hardscape surface to allow air flow and prevent any sealant damage. Remove plastic after the rain event to allow for evaporation and curing.
Will cold weather affect NanoPave JSS curing?
Since NanoPave JSS is water-based and curing is dependent upon evaporation, cold weather will often prolong the curing process of NanoPave JSS. It is not recommended to apply NanoPave JSS if the low temperature falls below 40 degrees during the application and curing process.
Will warm or hot weather affect NanoPave JSS curing?
It is recommended to apply NanoPave JSS when the surface temperature of the pavement is 85º F or less. It is very important to note the ambient temperature and surface temperature before application. For example, an 85º F day in the afternoon could product a much warmer surface temperature for pavers or stone in full sun – often as much as 20º F warmer. Temperatures above 90º F can cause NanoPave JSS to flash cure which can cause a number of unwanted side effects such as discoloration, tackiness, and stabilization failure. In warmer months it is recommended to apply NanoPave JSS in the early morning hours.
There is still a haze of dust after applying the jointing sand, can I still apply NanoPave JSS?
It is highly recommended that the surface be free of dust to prevent an undesirable finish. It is best to sweep area 2-3 times to assure a clean surface.
Can I apply NanoPave JSS if the hardscape paving material is still damp?
Yes. Avoid applying NanoPave JSS if the surface is oversaturated, as it can affect the ability of NanoPave JSS to fully absorb. Please refer to our weather guidelines for rain events, before and after installation.
Can I apply NanoPave JSS if the paving is set on concrete slab?
No. NanoPave JSS requires a sand bed on a compacted base-rock to assure adequate water drainage and evaporation. Mortar and concrete will not allow the water to efficiently drain through the stabilized jointing material (sand or crushed stone) and may destabilize the joints when oversaturated.
How soon after applying NanoPave JSS can I use the treated paving surface?
NanoPave JSS can cure as quickly as 12 hours in some conditions, but it is advised to wait 24 – 72 hours before allowing foot or vehicular traffic. If the surface is used before NanoPave JSS fully cures the joint material bond can be damaged and have an adverse affect the success of the installation.
How do I know the area treated with NanoPave JSS is fully cured?
The material will not be wet, tacky or soft. The joint material must be firm to the touch in order to use.
What should I do if it is taking a long time for the NanoPave JSS treated joints to become firm?
In normal conditions NanoPave JSS will cure within 24 – 72 hours, although curing is dependent upon evaporation of the water component. Curing can take longer if the weather is cold, overcast or the treated surface is an area that is shaded.
I applied NanoPave JSS and the joints are still wet and soft?
Allow the material to fully cure which is the total evaporation of the water component. Depending on weather conditions or shade, the curing process can take longer.
I applied NanoPave JSS, but the joint sand is dry and never became hard?
This is often a sign that either not enough NanoPave JSS was applied, or that an unsuitable jointing material was used. Loose joint sand can be re-treated with additional NanoPave JSS.-
COMPACTION OF JOINT MATERIALS:
Is compaction of jointing material required for narrow joints?
It is often stated by paving stone manufacturers to use a vibratory plate compactor to help settle the sand joints evenly. This is most common with joint widths of less than a ½” in width.
Is compaction of jointing material required for wider joints?
Although it is not required, hand tool compaction in wider joints can help prevent air pockets, inconsistencies, and abrasion. For joints wider than 1″, use a trowel or wooden block to compress. This process will help add density and strength.-
NEW PROJECTS:
What is the best way to ensure success on a NanoPave JSS project?
When planning a project from the beginning, all installation variables can be taken into consideration and recommended construction methods can be followed. Skipping steps or relying on components from an older installation can often times lead to problems or undesired results. The most important aspects to consider when using NanoPave JSS are using a suitable joint material, adhering to recommended application ratios, and acknowledging temperature and weather conditions during application and cure.-
EXISTING PROJECTS:
Can NanoPave JSS be used on existing hardscape installations (flagstone, pavers, brick, etc)?
Yes. It is highly recommended to clean, repair, and reset the hardscape pavement if needed. Next, remove existing and reinstall new jointing material. At this point it is often suitable to apply the NanoPave JSS product, although each project has its own set of variables. To ensure optimal results for existing projects, it is recommended to contact our Technical Support department directly at 877-356-2250.-
FINISHING TOUCHES & CLEANING:
What is the best way to clean my tools after applying the NanoPave JSS?
When finished applying NanoPave JSS, simply rinse off your tools with water. For pressurized sprayers it is recommended to rinse out the lines by spraying ½ – ¾ gallons of water through the system. If there are any clogs in the sprayer tip, use a soft bristle brush and water to remove. It is recommended to clean equipment immediately after use.-
MAINTENANCE:
How often do I need to apply a NanoPave JSS maintenance coat?
On average a maintenance coat will need to be applied every 2-4 years. Inclement weather conditions and heavier surface traffic may increase the need for a maintenance coat. The need for occasional maintenance is common throughout the life-span of a hardscape surface due to the loosening of areas from foot traffic and weather.
Heavy rain caused a few areas of joint material to erode, how can I repair?
A NanoPave JSS treated surface is very resistant to erosion, but water from heavy rains may cause minor erosion to occur. If this happens, simply re-apply crushed stone material to the eroded area as needed. Then re-apply NanoPave JSS to the loose material and use a trowel to lightly compact the material into place. Allow area to dry 24-72 hours.
What is the recommended method to repair any cracks or light erosion?
NanoPave JSS was designed to expand and contract in extreme temperatures, so cracking should be minimal. However there can be shifting of pavement in sand-set hardscape applications that can cause a separation from the jointing material. If cracks do occur they can be easily repaired by brushing or brooming joint material into the cracks (try to use the finer grains or screen the larger rock out for easier application and clean up). Apply the NanoPave JSS to solidify the new material. Allow a minimum of 24 hours to dry.
I am noticing loose material on the surface, do I need a maintenance coat?
Loose material will occur over time, but doesn’t affect the structural integrity. This is often a sign of an area that is used more. Treating these specific areas by spraying a light coat of NanoPave JSS to the affected joints will be sufficient to re-strengthen the surface. Remove any excess NanoPave JSS from the pavement surface.
How do I repair joints where pavers or flagstone have become dislodged or had to be replaced?
In most cases, the easiest way to repair is by mixing the jointing material with enough NanoPave JSS to make a consistent mixture (oatmeal consistency. Install the blended mixture into the affected areas and then lightly compress or trowel the material into place.-
LIFE CYCLE:
What should I expect from a NanoPave JSS treated surface?
NanoPave JSS is a durable, UV stable product, but still requires occasional care and maintenance. In average conditions a maintenance coat is recommended every 24 – 72 months. Much like a wood or stone sealant, the maintenance coat works to rejuvenate and strengthen the crushed stone, increasing the life of the surface. The maintenance process is dependent upon 2 factors; the amount of usage and weather conditions. Heavier usage and inclement weather events may reveal the need for minor repairs, and it is recommended to repair these areas promptly.-
STORAGE:
How should opened and unopened material be stored?
In either instance NanoPave JSS should be stored in an area that meets two vital conditions; no direct exposure to sunlight and within the recommended temperature range. The shelf-life of NP-JSS is 4+ years if stored in optimal conditions. For opened NP-JSS containers make sure that the container is airtight and the lid is securely fastened. If the original container has been compromised then it is recommended to transfer the product to a compatible container. Improper storage can result in the polymer formulation being compromised.-
