NanoPave Hardscape Sealer (NP-HS) is a water-based, VOC-free, nano-polymer sealant for hardscape surfaces including pavers, bricks, natural stone, and flagstone. It is also commonly used to seal decorative stone ground cover materials such as river cobble, beach pebbles, and specialty aggregates. NP-HS enhances the natural color of hardscape materials and ground covers.

NP-HS enhances and protects the natural beauty of hardscape surfaces using an ultra-high clarity, nano-polymer sealer technology. With excellent adhesion to both porous and dense surface materials, NP-HS provides protection without blushing, yellowing, or cracking. NP-HS is a breathable sealer that applies easily to interior or exterior hardscape surfaces and protects against UV degradation, staining, fading, and weather damage.

NanoPave Hardscape Sealer is available in (3) ready-to-use sheens; Natural Look Finish – Low Sheen; Enhanced Look Finish – Semi Gloss; Wet Look Finish – Gloss. Each is simple to apply using a pressurized pump sprayer in conjunction with a handheld squeegee or tight nap roller as needed.-


Before starting a project what should be done to ensure best results?

  1. Calculate the square footage of the project area to determine the required amount of NanoPave Hardscape Sealer needed.
  2. Check ambient and surface temperatures for application areas to ensure a suitable range for both installation and the curing process.
  3. Pause irrigation sprinklers and check weather forecast for any precipitation within 72 hours of applying NanoPave Hardscape Sealer.
  4. Perform a small test section to determine suitability of materials.


What should I expect from a surface treated with NanoPave Hardscape Sealer?

NanoPave Hardscape Sealer is a UV-resistant sealant solution for a wide range of hardscape surfacing products. The fast curing, ultra clear sealer enhances the natural colors of pavers, bricks, flagstone, and natural stone while also helping to prevent staining and fading. The nano-polymer formulation in NP-HS is specifically formulated to treat hardscape surfaces that commonly include joint materials, such as sand and decomposed granite (DG).

Why is NanoPave Hardscape Sealer better than other options?

NanoPave Hardscape Sealer enhances the appearance of most hardscape surface products and doubles as a protectant from staining and fading. The water-based, nano-polymer formulation found in NP-HS is an excellent alternative to hazardous, solvent-based sealers. NP-HS is VOC-free, ready-to-use, and environmentally safe for use around people, pets, and landscaping. It can be used for interior or exterior applications.

What is nano-polymer technology and why does it make NanoPave Hardscape Sealer a better choice?

NanoPave Hardscape Sealer was developed for optimum surface absorption and clarity for a wide range of application scenarios. Nano-polymers are small and consistent, which allows for a smooth seal and excellent adhesion to the hardscape paving surface.-


What are the most common projects to use NanoPave Hardscape Sealer on?

NanoPave Hardscape Sealer is most commonly used on hardscape walkways and patios constructed with pavers, bricks, flagstone, and natural stone in both residential and commercial application projects. NanoPave Hardscape Sealer is designed for use on hardscape surfaces with solidified joint material such as mortar, grout, stabilized polymeric sand or crushed stone. To stabilize loose jointing material such as sand or decomposed granite (DG), please refer to our NanoPave 2-in-1 Joint Stabilizer & Sealer (JSS) product.

Can NanoPave Hardscape Sealer 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 Hardscape Sealer 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 Hardscape Sealer be used as a 2-in-1 joint stabilizer & sealer (JSS)?

No, NanoPave Hardscape Sealer is specifically formulated with a nano-polymer blend that provides a protective, enhancing sealant coat to the hardscape surface. If joint stabilization is needed for an existing project, we recommend using NanoPave JSS to take advantage of the combination nano-polymer stabilization qualities specific to its formulation.

What are the most common small joint project applications for NanoPave Hardscape Sealer?

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 filled with a joint material, commonly no more than ¼” wide.

Can NanoPave Hardscape Sealer be used to seal pea gravel, beach pebbles, and other decorative stones?

Yes. NanoPave Hardscape Sealer is commonly used to enhance the natural beauty of decorative stone ground covers. Simply apply NP-HS evenly over the stones with a pressurized sprayer at the recommended rates. For optimal coverage, use a rake to turn the surface level stones over and then apply more sealer as needed.-


What tools are required to apply NanoPave Hardscape Sealer?

Pressurized sprayer (25-40 psi), foam rubber squeegee, tight nap roller (alternative to squeegee), sponge, plastic to cover surrounding areas from accidental spills or overspray.

What is the best tool for NanoPave Hardscape Sealer application?

Using a pressurized sprayer (garden, pump or backpack are recommended) is the preferred method. NP-HS can also be applied with a tight nap roller in some scenarios although it is strongly recommended to use a sprayer for any surface with large joints or loose joint material.-


How is NanoPave Hardscape Sealer applied?

Using a pressurized sprayer (garden, pump or backpack are recommended) is the preferred method. NP-HS can also be applied with a tight nap roller in some scenarios although it is strongly recommended to use a sprayer for any surface with large joints or loose joint material.

Can I apply multiple coats of NanoPave Hardscape Sealer?

To increase sheen to desired aesthetic, a second coat of NP-HS may be applied at twice the initial application rate, once cured. Do not divide recommended initial application rates into multiple coats. Dividing application coats of NanoPave Hardscape Sealer is unnecessary, and in turn, can create other issues such as stacking, flashing or modified surface aesthetic and sheen. Use a foam rubber squeegee or equivalent to evenly distribute or remove excess or standing NP-HS from the surface.

How long does it take for NanoPave Hardscape Sealer to cure?

In optimal conditions the surface will cure in 6 – 12 hours. Humidity, temperature and atmospheric conditions can cause the curing time windows to fluctuate. NanoPave Hardscape Sealer is a water-based product and the curing process is based on evaporation of the water component.

How soon can I apply NanoPave Hardscape Sealer before and after a rain event?

It is not recommended to apply NanoPave Hardscape Sealer 24 – 48 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 Hardscape Sealer should be avoided. If rain is forecast within 48 hours it is recommended to wait for dryer conditions.

What should I do if it rains before NanoPave Hardscape Sealer 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 airflow and prevent any sealant damage. Remove plastic after the rain event to allow for evaporation and curing.

Will colder weather affect the NanoPave Hardscape Sealer curing process?

Since NanoPave Hardscape Sealer is water-based and curing is dependent upon evaporation, cold weather will often prolong the curing process of NanoPave Hardscape Sealer. It is not recommended to apply NanoPave Hardscape Sealer if the low temperature falls below 40 degrees during the application and curing process.

Can I apply NanoPave Hardscape Sealer in hot conditions?

It is recommended to apply NanoPave Hardscape Sealer when the surface temperature of the pavement is 85 degrees 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 Hardscape Sealer 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 Hardscape Sealer in the early morning hours.

Can I apply NanoPave Hardscape Sealer if the hardscape paving material is still damp?

Yes. Avoid applying NanoPave Hardscape Sealer if the surface is oversaturated, as it can affect the ability of NanoPave Hardscape Sealer to fully absorb. Please refer to our weather guidelines for rain events, before and after installation.

Can I apply NanoPave Hardscape Sealer over polymeric sand joint material?

Yes. NanoPave Hardscape Sealer is designed for use on existing hardscape surfaces including paver, brick, and natural stone areas where polymeric sand has been used as a joint material. This is also true for mortar joints commonly seen in flagstone projects.

How soon after applying NanoPave Hardscape Sealer can I use the treated paving surface?

NanoPave Hardscape Sealer can cure as quickly as 6 hours in some conditions, but it is advised to wait 24 – 48 hours before allowing foot or vehicular traffic.

How do I know the area treated with NanoPave Hardscape Sealer is fully cured?

The hardscape surface will be dry to the touch and completely clear. If any areas appear to be a milky white color, it typically needs more time to cure.

Can NanoPave Hardscape Sealer be applied to hardscape areas around swimming pools or hot tubs?

Yes. NanoPave Hardscape Sealer is safe for use around pools, hot tubs, and areas where chlorinated water will come into contact.

How do I proceed if my hardscape surface has stains or efflorescence?

It is very important for the hardscape surface to be completely clean before sealing. Applying sealer over stains or efflorescence will likely result in an undesirable finish. NanoPave Hardscape Sealer will not hide or cover up stains, deep scratches, tire marks, or efflorescence. Depending on the hardscape material, there are several ways to clean the surface including pressure washing or scrubbing with a brush and soap or detergent. For bad staining or efflorescence, Acetone or Muriatic Acid may be used. Consult the hardscape material supplier or manufacturer for more information, always wear appropriate personal protective equipment (PPE), and exercise caution when using chemicals.-


What is the best way to ensure success on a NanoPave Hardscape Sealer project?

When planning a project from the beginning, it is important the surface area is clean and matches your expectations visually before applying NP-HS. Blemishes or efflorescence should be cleaned before sealing. Other important aspects to consider when using NanoPave Hardscape Sealer are adhering to recommended application ratios and acknowledging temperature and weather conditions during application and cure.-


Can NanoPave Hardscape Sealer 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. If the area has been sealed previously with another brand of sealer or coating, a test section should be performed using NP-HS before starting. In some cases, the old sealer or coating may need to be removed with a sealant stripper before application. At this point it is often suitable to apply the NanoPave Hardscape Sealer 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.-


What is the best way to clean my tools after applying the NanoPave Hardscape Sealer?

When finished applying NanoPave Hardscape Sealer, simply rinse off your tools with water. For pressurized sprayers it is recommended to rinse out the lines by spraying clean 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.-


How often do I need to apply a NanoPave Hardscape Sealer maintenance coat?

On average a maintenance coat will need to be applied every 24 – 48 months. 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.-


What should I expect from a NanoPave Hardscape Sealer treated surface?

NanoPave Hardscape Sealer is a durable, UV stable product, but still requires occasional care and maintenance. In average conditions a maintenance coat is recommended every 24 – 48 months. The maintenance process is dependent upon 2 factors; the amount of usage and weather conditions. –


How should opened and unopened material be stored?

In either instance NanoPave Hardscape Sealer 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-HS is 4+ years if stored in optimal conditions. For opened NP-HS 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.-
