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 having to reseal my pool deck every year, I had Nat. Sealing reseal my Pool Deck 3 months ago with their patented COATING. From start to finish (Sales w/ Kenny to Tech w/ Mark) everything went Smooth, and when they say Non slip they mean non slip ! Exceeded expectations !

Highly recommend this company. These guys are awesome to deal with. Kenny was super helpful guiding me to the right choice for sealing the pavers. Went with the microbead 3-part sealer, which is slip resistant and really brought out the amazing colors of our pavers. Mark came out to complete the project and he was awesome. Super knowledgeable about different types of stones and surfaces and which products work and which fail and why.

Kenny, Mark, and team were great to work with. We installed limestone pavers on a large patio and our pool area 3 years ago and, to our surprise, the pavers were very slick even though rated for use near the pool. This led to us having angst whenever having friends/family over and the worry of someone (especially kids) slipping and having a major injury. I did a quick Google search and found National Sealing Co and their multiple 5* reviews. At first I couldn't believe it to be true, and also wasn't sure how an outfit reliably traveled the country to apply this technology. After dealing with Kenny and Mark, it was clear to see they have their process and product dialed in over many years of operation. We went with the top tier option to maximize non-slip features and longevity, and am glad we did so. Thank you for allowing us to *really* enjoy our backyard space. Cheers from Arizona!

The owner of National Sealing Ken Kline and his team provided us with outstanding service from beginning to end. National Sealing's exclusive bead sealing process is far superior to any other product and the slightly higher cost is well worth the investment. My 1000 sf. leathered marble pool deck looks brand new, is slip free and comfortable to walk bare foot on. Do not waste your money with any other sealing company or product.

Kenny and team were great to deal with. We have a 6,000ft stamped concrete patio around pool and has been very slippery since we built it, found National Sealing and they are the first company that I truly feel fixed my problem. Everything looks great and looks like there is plenty of traction. We cant wait until it warms up a bit to give everything a good test. Was very nice to deal with folks that know what they are talking about

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
