Durable Non-Slip Applications

Don't Let Inferior Sealers and Distance Deny You the Best Pool Deck Protection in America

Advanced Non-Slip Pool Deck Protection

At National Sealing, we’ve developed the most durable non-slip application for pool decks using our Proprietary 3-Part Coating and Nano Non-Slip Beads. Unlike local contractors who rely on common sealers and brittle “shark grip” additives, our system is engineered for long-lasting protection and safety:

3 - 5× more durable than standard non-slip sealers
3-Part Coating enhances stone more than common sealers
Proprietary Nano Non-Slip Beads – the most durable non-slip application in the U.S.
Largest Paver Sealing Co. in the U.S., established 2001, with 25+ years of experience

By COMPARISON: The Only Option Available for local contractors/handymen

So what’s available locally? Local handymen and contractors only have access to common sealers. To make them “non-slip,” they mix in shark grip powder or even play sand. Many contractors are now trying to capitalize on National Sealing's success by advertising a so-called “coating.” Nope — it’s just a sealer. Remember: if it’s not National Sealing, it’s not a coating.

Brittle texture that wears down within a year
Frequent, costly reapplications
Layered sealers that eventually fail and require stripping

The Only Real Solution

Our 3-Part Coating + Nano Non-Slip System:

If it isn't National Sealing - it isn't a coating. Many local contractors are attempting to offer "Coating" – the 3-Part Coating System is a process developed by National Sealing decades ago. Local folks are limited to using common sealers and simply want to capitalize on our success. Our 3-part coating is proprietary technology not available from other sources.

We had a great experience with this company. After trying 3 non-slip sealants that didn’t work for our pool deck (limestone), we decided to contact Kenny, he was quick to reply and very kind answering all my questions. I finally have a non- slip pool deck, I have recommended this company to everyone.

Kenny did a fantastic job of sealing our pool pavers! I highly recommend National paver Sealing Company! You won’t be disappointed!

Jesus Guerra

Excellent customer service and excellent product deck looks magnificent show up on said day explained everything about process and product answered my questions very professionally and performed the work without any hiccups. Highly recommend this company.

Upon contacting Kenny at National Sealing Co, he took the time to explain the differences in processes to where clearly the value was in the three part coating with nano beads. Within a few days we scheduled to have it done at which time Ashton started wtih the pressure cleaning the surface nicely and let it dry for 2 hours. Upon which time, Mark showed up to apply product (w/nano beads). The whole process was seamless. Upon completion of drying the surface coated with nano beads, it definitely provides a non-slip surface as well as a consistent rich look. No we are looking forward to not having to seal the marble every year as Kenny described.

Pricey but worth the money. Our travertine pool deck was a slippery death trap before applying the non slip coating. Professional, timely and easy to work with. Go for it!

Elizabeth Denton

Amazing product!! We are a new build & picked marble for our pool decking. We were told that the marble would not be slippery when it got wet - which ended up not being true. I contacted National Sealing & spoke with Kenny. He took the time to explain their product & process. Mark arrived to apply the product & was extremely professional. We are extremely happy with the results. Our pool decking is no longer slippery - kids & teens can run around now & I no longer have to stress that someone is going to slip & fall. I highly recommend National Sealing.

There’s only (4) Options for Protection on the Entire Planet

(2 of which we’ve developed)

Option	Description	Durability	Risks / Drawbacks	Best For
Option 1	Penetrating / Impregnating Sealer	6–12 months	Creates a slip hazard, rapid UV fading, no surface protection, and costly stripping over time	Interior stone (not recommended for exterior decks)
Option 2	Sealer + Shark Grip or Play Sand	~1 year	Brittle, wears down fast, frequent reapplications, and layering leads to failure	DIY or local contractor quick fixes
Option 3	Sealer + Proprietary Nano Non-Slip Beads	~3 years	Still uses a sealer and therefore is at the mercy of the limited life of a sealer	Budget-conscious upgrade over local options
Option 4	Proprietary 3-Part Coating + Nano Non-Slip Beads	4–5 years +	Superior durability; enhances color, protects surface, and provides the longest-lasting non-slip protection in the U.S.	Homeowners seeking maximum protection, safety, and beauty

Careful: The Penetrating / Impregnating Sealer Deception That’s Destroying Your Investment

The “penetrating / impregnating sealer” story has been passed around like a game of telephone. Many homeowners (and even pool contractors) are told to use it on Travertine or Marble. While these products are great for interior applications (countertops), they are the wrong choice for exterior applications such as pool decks.

NOTE: Unbiased approach, as we can certainly apply a penetrating/impregnating sealer — in fact, it’s listed as Option #1 on our site. However, based on decades of experience, we do not recommend it for exterior use.

Concerns with Penetrating / Impregnating Sealers:

Slip hazard – water forced to sit on the surface creates dangerous slick spots
Short lifespan – breaks down in just 6–12 months under the sun and chemicals
UV fading – up to 50% color loss in 3 years (travertine)
Surface damage – saltwater and pool chemicals degrade the stone
Risk of staining from spills, potted plants, etc…
High maintenance – frequent re-applications build up residue, eventually requiring costly stripping

Does this look slick to you??

Why are penetrating / impregnating sealers still pushed or applied?

Because they’re quick and easy for contractors. One application, done. But you’re left with a slick deck, faded stone, costly re-applications, and expensive long-term damage.

Comparing Penetrating Sealer vs. National Sealing 3-Part Coating

	Penetrating / Impregnating Sealer	National Sealing 3-Part Coating + Nano Non-Slip 8e
Feature / Concern	None - Surface remains exposed to UV, stains, pool chemicals	Full barrier protects against UV fade, staining, salt, chlorine
Durability	6 - 12 months outdoors before reapplication	Lasts 3 - 5x longer (multi-year protection)
Appearance	Slight or no enhancement, stone still fades	Rich color enhancement preserves "new" look
Slip Resistance	Can actually increase slipperiness	Integrated patented Nano Non-Slip Beads for safety
Maintenance	Frequent reapplications; buildup can fall and require striping	Low-maintenance coating designed for longevity
Cost Over Time	Low upfront, but costly due to frequent re-sealing	Higher upfront, but far lower lifecycle cost
