NanoPave Concrete Sealer

NanoPave Concrete Sealer


NanoPave Concrete Sealer (NP-CS) is a water-based, VOC-free, nano-polymer sealant for finished concrete surfaces including smooth, broomed, colored, stamped, exposed aggregate, and more. NP-CS enhances and protects the natural beauty of embellished concrete surfaces using an ultra-high clarity, nano-polymer sealer technology. With excellent adhesion to concrete despite the finishing technique used, NP-CS provides protection without blushing, yellowing, or cracking.

NanoPave Concrete Sealer is a breathable sealer that applies easily to interior or exterior concrete surfaces and protects against UV degradation, staining, fading, and weather damage. NP-CS 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 Concrete 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 Concrete Sealer.
  4. Perform a small test section to determine suitability of materials.


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

NanoPave Concrete Sealer is a UV-resistant sealant solution for a wide range of concrete surfaces. The fast curing, ultra clear sealer enhances colored and stamped concrete while also helping to prevent staining and fading. The nano-polymer formulation in NP-CS is specifically formulated to treat various concrete surface finishes.

Why is NanoPave Concrete Sealer better than other options?

NanoPave Concrete Sealer enhances the appearance of most concrete surfaces and doubles as a protectant from staining and fading. The water-based, nano-polymer formulation found in NP-CS is an excellent alternative to hazardous, solvent-based sealers. NP-CS 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 Concrete Sealer a better choice?

NanoPave Concrete 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 Concrete Sealer on?

NanoPave Concrete Sealer is most commonly used on concrete walkways and patios in both residential and commercial application projects. NanoPave Concrete Sealer is designed for use on many types of concrete finishes including broomed, smooth, exposed aggregate, salt, colored, and stamped.

Can NanoPave Concrete 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 Concrete Sealer before performing a test section. 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 Concrete Sealer be used concrete step stones with joint material?

In a situation where concrete stepping stones are situated with either mortar, stabilized sand or crushed stone joint material, or another type of loose aggregate ground cover, it is recommended to use NanoPave Hardscape Sealer to seal the stones and joint areas. NanoPave Hardscape Sealer is specifically formulated to meet the adhesion needs for stabilized joint material or loose ground cover materials. To stabilize sand or crushed stone mixes used as joint material, we strongly recommend using NanoPave 2-in-1 Joint Stabilizer & Sealer (JSS) where applicable.



What tools are required to apply NanoPave Concrete 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 Concrete Sealer application?

Using a pressurized sprayer (garden, pump or backpack are recommended) is the preferred method. NP-CS can also be applied with a tight nap roller in some scenarios although it is strongly recommended to use a sprayer for any surface uneven texture or stamp work.



How is NanoPave Concrete Sealer applied?

Using a pressurized sprayer, apply NanoPave Concrete Sealer at the recommended rates based on your concrete surface. Evenly apply NP-CS over the entire surface, including the expansion joints. After applying NanoPave Concrete Sealer at the recommended coverage rate, evenly distribute any residual liquid that hasn’t absorbed into the surface by using a foam rubber squeegee. Use a grout sponge to remove any additional material if needed.

Can I apply multiple coats of NanoPave Concrete Sealer?

To increase sheen to desired aesthetic, a second coat of NP-CS 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 Concrete 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-CS from the surface.

How long does it take for NanoPave Concrete 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 Concrete Sealer is a water-based product and the curing process is based on evaporation of the water component.

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

It is not recommended to apply NanoPave Concrete 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 Concrete 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 Concrete 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 Concrete Sealer curing process?

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

Can I apply NanoPave Concrete Sealer in hot conditions?

It is recommended to apply NanoPave Concrete 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 concrete in full sun - often as much as 20º F warmer. Temperatures above 90º F can cause NanoPave Concrete 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 Concrete Sealer in the early morning hours.

Can I apply NanoPave Concrete Sealer if the concrete surface is still damp?

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

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

NanoPave Concrete 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 Concrete 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 Concrete Sealer be applied to concrete areas around swimming pools or hot tubs?

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

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

It is very important for the concrete surface to be completely clean before sealing. Applying sealer over stains or efflorescence will likely result in an undesirable finish. NanoPave Concrete Sealer will not hide or cover up stains, deep scratches, tire marks, or efflorescence. Depending on the concrete finish, 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 a concrete supplier or contractor 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 Concrete 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-CS. Blemishes or efflorescence should be cleaned before sealing. Other important aspects to consider when using NanoPave Concrete Sealer are adhering to recommended application ratios and acknowledging temperature and weather conditions during application and cure.



Can NanoPave Concrete Sealer be used on an older concrete installations?

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-CS 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 Concrete 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 Concrete Sealer?

When finished applying NanoPave Concrete 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 Concrete 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 concrete surface due to wear and tear from foot traffic and weather.



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

NanoPave Concrete 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 Concrete 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-CS is 4+ years if stored in optimal conditions. For opened NP-CS containers make sure that the container is airtight and the lid is securely fastened.
