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
Products are not sold, applications only by Trained Technicians.

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.

After researching various companies and methods for sealing our marble pool patio, I concluded that the proprietary method used by National Sealing company was superior. Ultimately, time will tell but the finished project looks very nice as advertised. Grain patterns look very nice and the glass nano particles feel like they prevent slipperiness as planned. Scheduling was good (not long wait) and the installer showed up on time. Work was done in a timely manner and he took care to avoid hitting our nearby wood deck with application materials (masked the wood). Overall it was a very good experience and I'm optimistic that this product will last much longer than a regular pool deck sealer. I would highly recommend them.

Kenny and his crew were great to work with! I did a lot of research and am glad I chose their company. We have a lot of travertine and it looks great and I have peace of mind knowing it's protected for years now!

The team did an excellent job. Kenney spend a good amount of time understanding our needs and advising on the best solution. We know have a surface with more grip and longer term sealing solution

We had our patio extended and tiled with travertine last summer. It looked beautiful but was so slippery! We tried a couple of different no slip products on small areas to see how they did and nothing worked. Found National Sealing and was impressed by reviews so we took a chance. They communicated well and got to us in a relatively timely manner considering they are in Florida and we’re in Texas and it was worth every minute waited and every penny paid! I don’t have to follow my grandkids around to catch them when they slip because no one’s slipping anymore! The sealant is clear and added a lovely shine. It looks beautiful! So happy we found them!!

I used National Sealing Co to seal the travertine around my swimming pool. I was initially a little hesitant to use a company based outside my state, but reviews on line were solid enough I decided to give them a try. The scheduling was relatively easy. Their applicator came by as scheduled, was courteous, hard working and did a very good job with the product application. I like the color enhancing, sheen and good traction of the travertine post sealer application. I will update this review over the next couple of years depending on how well the product holds up over time, but am currently very happy with my decision to go with National Sealing Co.

Ashton did an excellent job applying the sealant with the nano beads to our marble pool deck for a non slippery surface.

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
