I live in California and have over 4000 ft.² of travertine pavers around my pool, patio area and Entry.  When wet the Travertine pavers become extremely slippery.   One of my grandchildren took a dangerous fall. And thus, I was on the hunt for an anti-skid product.  Problem was nothing actually worked that well. I had applied several products and had companies come out, but all to no avail.

And somehow I found Kenny Kline at National Sealing.  He was very patient and knowledgeable with me. Kenny offered to send me a sample which I thought was wonderful ! I could feel, touch, and  see what it would actually look like.  That’s when I realized I had found the best possible product around, nothing came Anywhere close to this anti skid product.  Kenny sent Mark out from Florida and He meticulously applied the product to all the Travertine pavers.  We are so happy we chose National Sealing.  I know I can confidently recommend this product, and have, to my friends and family.  It has kept us all safe from dangerous falls.
Give them a call and ask for a sample, you’ll see what I’m talking about.

Kenny got right back to me and had a price for the job in one day. He gave me the best price and completed the job just as he promised. The online billing was convenient and easy. There is no one else I will call for the next sealing job.

Kenny was informative and professional.  They guys showed up a day earlier than originally planned, which was good.  The weather did us no favors, but it got done.  The travertine looks great and it’s not slick when it’s wet.

Fantastic Service!!
My expectations were exceeded.  Both Kenny and Mark were absolute professionals I am totally satisfied with the outcome and highly recommend National Sealing.

National Sealing did a great job applying their non slip coating to our travertine deck.  Although they traveled cross country, they showed up when they said they would and worked around the weather conditions.  I’m no longer concerned about our kids slipping around the pool area. We would highly recommend them.

Very pleased with the results.  I have pavers that are almost white and are fairly smooth and porous.  Every thing seemed to stain them that touched them, including dirt tracked by yard guys.  So far, I’ve been able to wash away the dirt and stains with water and a broom.  I was told ahead of time that they may be a little slippery when wet and they are but I decided against adding a product that would add a little texture.  We are more careful walking when pavers are wet and it has been fine.

They did a beautiful job, in every respect. Just a great company to work with!

Kenny and his team came up to NYC and were able to restore to original color. We are pleased with the work and the professionalism. Our pavers were dull and turning white, now they are in great shape and not faded. Mark was great in explaining the process.
Thank you

Kenny was great in providing information getting a quote out and having the work done just as planned. Very happy.

I have been using National Sealers for 15 years. Their expert advice, quality workmanship and reliable service are unsurpassed in Florida. As a Quality Control director I know I can  always rely on their  professionalism.
Under   the intense  pressure of ever present  deadlines and contractual obligations National has never failed to answer the bell.   If I have a question about the constantly  changing rules and regulations governing our industry,  I can always rely on Kenny to be up to date, knowledgeable, and informative.
How many Owner/CEO’s give you their personal cell phone number…..and answer it!!!

Great service and a splendid product! Mark came up to North Carolina (all the while dodging storms) and had the job done in just a few hours. The whole team was professional, courteous, and a pleasure to work with. The price was right and the end result is just what we’d hoped for. Highly recommended!

Kenny and his team could not have been more professional.  Amazing experience from start to finish.  We had nearly 500 sq.ft. of “slippery when wet” travertine pavers that are now safe and just as beautiful as ever. Thank you, Kenny!

Great company! they did a great job at our hotel. We had a minor issue in one of the areas, but Kenny handled well and professionally. Great people to work with. The product itself was a great solution for our slippery floor.

Was a terrific experience start to finish.  Kenny spent quite a bit of time talking me through the various types of sealers available in the market for travertine stone and their pros and cons, and explained the difference in the national seal product.  While I was a bit nervous scheduling a company out of Florida to come do the job in Houston, Kenny reassured me this was normal business for them.  We scheduled the appointment out about a month and install was on time.  Mark was a pleasure to work with and took the time to explain the application and cleaning process to me.  It rained hard about 24 hours after application and the water just beaded up. I sprayed off the deck about 48 hours after install and the dirt and surface stains just washed away.  Customer service was excellent.  Product did exactly what was advertised.  I’ll be interested to see how long the seal maintains its integrity.  Wish all contractors were as conscientious!  All around was a great experience.

National Sealing just did a job for our community.  They had to deal with vehicle traffic of over 3000 cars a day and uncooperative weather and still they did an outstanding job for the price they quoted.  They did so well, we barely knew they were there.  We will be repeat customers!

National sealing were fantastic! I had existing porcelain tile on my patio and built a pool right next to it. However,  it would get so slippery that I thought we’d have to tear it all out until I spoke with Kenny. He assured me that their treatment would work with all types of floors and he was right. I saved money and stress and National’s work was professional and came out beautiful. I recommend them to all pool owners who want non slip floor treatment

Kenny is the best in explaining on the importance of sealing and coating your pavers.  Our limestone pavers came out looking shinny and new and also don’t have to worry about them being slippery when its wet.  Thank you again for all your help.

Kenny, at National Sealing was extremely helpful when he came to discuss their services. I was initially just going to seal my pavers but he indicated they had a dying process that would make them look brand new. I elected to have them dyed and they turned out amazing. I couldn’t be happier with the end result.

Excellent company to deal with.  My initial call was promptly returned by Kenny who answered all of my questions and scheduled my job timely.  My pool deck was a two day process and both days the crews showed up on time and completed their respective tasks.  These folks were a pleasure to deal with and I recommend them.

My pool deck is crema bella marble and was slick as ice.  We loved the look, but the kids would never be able to enjoy the pool deck without injury unless we added a non-skid surface.  We explored sealing and sharkskin, but the vendor advised us it would need to be rolled on leaving streaks on our brand new marble, couldn’t be rained on before or after (Florida in June tends to be pretty rainy) or it would “fog up” and would need to be reapplied frequently as it wore down.  National Sealing’s anti slip product has none of these drawbacks.  The product helped to bring out the variations in natural stone and it looks amazing.  The kids have been running on the wet surface for a couple of weeks now without anyone slipping.  The product went down evenly across the entire surface appears to be as durable as advertised.  This may not be the cheapest solution, but this is money well spent in my opinion.

I had a major problem with failed sealer as well as faded pavers on my 10 year old circular driveway. The pavers were white and looked horrible. I hired multiple companies to fix this issue to no avail, though spending thousands of dollars. I thought I would have to replace my pavers at a cost that exceeded 20k. I then stumbled upon Kenny Kline and his company National Sealing Company. I spoke to him over the phone and he had a thorough understanding of the issues. His company used a water pressure blaster(capable of 40k psi) to clean my pavers. This thoroughly removed all traces of the failed sealer and did not damage the pavers. They then sealed and dyed the pavers. The color match was perfect. This dyeing process is not like paint or stain, and the pavers have a natural look. They literally look brand new. This is no hype. The price was very reasonable. I cannot say enough good things regarding this company, and they are worth every penny I paid them plus more! Thanks again Kenny!!

Kenny and his team did a fantastic job.  He called me right back and his quote was very good – booked the job for the following week.  He spent time before and during to explain process and care.  Patio and driveway look fantastic.  Highly recommend.

This is the 2nd time I have used National Sealing so that should tell you that I was very impressed with their work the first time around.  I installed new pavers in my pool area and they were very slippery.  They did an awesome job with their coating and nano beads install and no longer slippery. They also coated my driveway with their dye process and it looks brand new.  Mark and Kenny are honest and trustworthy and explain the process carefully.  Thanks guys for another Great Job!

Very professional. Great job. My faded pavers look so much better. Great communication and delivered services on time as promised. A little more expensive than I thought, but worth it.

National sealing did a great job on our pavers,  now when we come home the driveway looks new!  Also were able to match pretty close an addition we had to do with different pavers.  Kenny was great to work with and always communicated!

I never write reviews mostly because all the work I’ve had done here in miami has been subpar/incomplete or simply disorganized and unprofessional. I am elated to say that my experience with National Sealing Company has been excellent. I needed my huge brick fireplace to be “revived” prior to placing a TV. The brick was drab, dull and grayish –the catch–I needed it done within 24 hours because the TV installers were scheduled 2 days later.  Not only did Kenny rearrange his schedule to send me someone the next day (and in the evening which was better for me) but his worker Mark was OUTSTANDING.  The brick became a beautiful red orange color that it once was. Mark showed up on time. He made sure all my furniture was protected and was kind, courteous and professional. Further, I  showed him a problem that I had with my outdoor porcelain tile. He recognized the problem and gave me a tip to correct the problem.  ( Saving almost two thousand dollars that a tile contractor quoted me) all in all, I  couldn’t be more pleased.

Can’t go wrong with National Sealing Company! Our driveway is beautiful!

Kenny, Jason & Co. were a pleasure to work with. They explained everything in detail & did a very thorough and professional job.  I would recommend National Sealing to my friends & neighbors.

National Sealing has a great product. I was looking for a sealant that accomplished both a wet look and a non slip surface- that is what National Sealing provided.  Kenny and the team were prompt and responsive and did a great job.

On time and communicative. Used as an anti-slip coating to newly installed travertine. Looks great!  Price is a little more than traditional sealer but is supposed to last 3-5Xs longer, so in the long run well worth it compared to sealing every year or two to protect your investment. The anti-slip, glass nano bead finish is mildly abrasive but well worth the piece of mind when elderly, children, complacent, or other slip-prone persons (so pretty much everyone) will be on “your” floor. Will try to update this review in a few years to talk to the product’s longevity.

Kenny and Mark are the bomb! Did a great job on my 25,000 square foot 60 year old driveway!

Kenny and his crew did a fantastic Job. They arrived on time, and completed the job quickly. I reached out to Kenny on a late Friday afternoon with a small window to get the job done. He was able to facilitate my needs in the required time allotted. Thanks Kenny and crew!

Kenny did a great job on my driveway , we are pleases with the work done .i would recommend his service to anyone.

We needed the travertine pavers around our pool resealed because they were slippery and I knew it was only a matter of time before someone slipped and got hurt. We called National Sealing and they were incredibly prompt with giving a quote and setting up the job. They were friendly, reasonably priced and stand behind their product. This weekend the kiddos were around the pool and I wasn’t nervous!  I’d highly recommend.

We had just finished redoing our pool and Lanai deck with Marble. I was very excited to swim in our new pool and as I came out I did a little slide dance on the slippery marble. We contracted to have a non-skid sealer done which when wet was also like a skating rink.

After doing some research we hired National Sealing Who removed the original sealer we just had put on and installed their non-skid finish. Once again I was very excited to be able to use my pool and after getting my feet wet I tried to break my neck and couldn’t. Wet or dry their finish is awesome

National Sealing treated our Pool lanai Travertine tile and their service was very good. I dealt with Kenny for the quoting process and Mark for the application process. Both were a pleasure to work with. I recommend National Sealing for this type of process.

We had a large very faded brick patio seal/dye coated. I’m very happy how it turned out. It looks naturally new. The color and sealer combination is top quality product. Both Ken and Mark are very professional  and knowledgeable and provide a great service. The applicator Mark is very skillful in how he mixes the formula and applies the product. I highly recommend this company and product.

Overall this was a good experience. Big improvement over badly faded builder grade pavers! The process was quick and Mark the installer was thorough in explaining what the process was and what the results would be.

While the process was expensive it was much less expensive than replacing the pavers.

Only suggestion is to roll on the product along the edges of the project rather than spraying it.  Spraying works fine and is pretty consistent in coverage in the center of the project.  The edges are less consistent in coverage.

Nice work, timely and very professional. I would recommend.

I highly recommend you skip the other non slip pool treatments out there and just go with National Sealing. I contracted out and had two other Non Slip Products installed on our pool deck that did nothing.

Mark from National Sealing came on time, on budget and delivered a Non Slip Solution that simply WORKS! And best of all my Wife is extremely happy for it always seemed she was the one slipping the most.

I can’t believe the results! Never thought my pavers would get their color back. This was by far the best way and most economical way to update our driveway. Thanks Kenny and Mark!

Unbelievable! My husband and I are extremely pleased. Kenny made the process easy and Marc was charismatic and professional. Our pavers went from faded to looking as if the were brand new. I would strongly recommend this company to anyone. Great service, easy billing and great product!

Very responsive and helpful. We needed non-slip coating on a pool bathroom floor to satisfy health department requirements. National Sealing took care of it for us quickly and easily. Product works very well and does not change the original look of the tile.

After our pool company scratched our brand new travertine, we knew we needed to get it sealed right away. We did a lot of research and found National Sealing had the best warranty. They were able to get us in within a few weeks, did a beautiful job, were quick and on time, friendly and knowledgeable. We are so happy with how our travertine looks! Worth a little extra cost to have a product that will last. Thank you so much!

Kenny was wonderful and so responsive from beginning to end (even while abroad on vacation), the work was completed when they promised and it came out great. We had our entire patio area sealed because it was way too slippery and since then we have had no issues. Amazing!

We had a fantastic experience with National Sealing Company! The process of renewing our 14 year old paver patio was easy, affordable and we are thrilled with the result. Kenny and Mark were true professionals guiding us through the process, scheduling and application. Our 14 year old paver patio looks brand new. The end result was even better than we could have imagined. How many home improvement projects turn out like that?  We highly recommend National Sealing Company!!!

Best money spent in a while.

I looked and tried several products and hire some people to treat our marble pool deck, they said acid will be the only thing that works, until I found National Sealing.

I spoke to Kenny and he said he had the right product for me ( like I haven’t heard that before I said) I schedule the job and Mark came in in the morning and once again I said is going to work went it gets wet? Of course, is going to work he said in his Australian accent. About 2 hours later he was done, I could not wait to try it out, 5 hours later and when it was all dried to the touch I wet my foot on the pool and stepped on the deck and no slip, Zero slip, I even tried harder and running and nothing no slipping not even a little, I highly recommend these guys.

Great people and great service. I wouldn’t hesitate to recommend this company and use them again myself! Thanks Kenny!

Rarely do I post reviews but the experience w National Sealing was so impressive, we wanted to share.  We were left in a pinch from our pool renovation company, called National Sealing on a Saturday, they came on Monday to give us an estimate – fair and thorough – and did the work on Thursday!  Professional, easy to work with and a great job!

We’ve had our pavers dyed by National Sealing and they look outstanding! Kenny and Mark are professional, responsive and a pleasure to deal with.

I had a skating rink after sealing the travertine pavers around my pool. I looked everywhere on the internet for possible solutions and came across  National Sealing. I spoke with a very knowledgeable Kenny who explained to me my options. After in depth research on their work at different locations in the US and abroad I decided to give it a try. Mark arrived on time for the service appointment and it was fun chatting with him while he worked. Three pool parties later with no less than five kids running around I feel safe to say I made the best decision for everyone’s safety. My wife and I are very happy with the outcome. Kenny and Mark, thank you for your very affordable and effective product and for making  business with you a pleasurable experience.

We made a mess of our sidewalks when we sealed them twice and made them incredibly slick when it rained. Brilliant I know. We are a wedding venue and we couldn’t have the brides and guests slipping and, believe me it was slick as ice. I was desperate for a solution when I called Kenny at National Sealing and they promised a non-slick surface while keeping the same look. They delivered 100%.  It was worth the price and the surface is beautiful and grippy. I would do it again in a second.

Great Job they met and exceeded our schedule and performed the work in a professional manner. The non slip coating they installed came out great and our client was very satisfied with the outcome.

We had a Great experience with National Sealing. After years of regular pressure washing and sealing our pavers just did not look good anymore. We were ready to replace 10,000 square feet of pavers. In researching our options we found National Sealing. Kenny explained our options and the process completely. We took a chance and hoped for the best. The results were beyond our expectations as our pavers look almost new. We would definitely use National Sealing again.

Great job sealing and coating my travertine. Martel did a great job applying the anti slip beads keeping
In mind protecting my property. Made a great look to the travertine with dealer. Would definitely recommend National Sealing and Kenny. Thanks A definite job well done you guys are the best

I have a stamped concrete driveway that resembles slate. It looks beautiful but is a nightmare during rain and snow events. No local company had a solution. The non slip coating is amazing. The tech…Marc explained the process and completed the project is a few hours. We are very please not only with the product but also with Kenny & Marc. Well Done!

As a picky Individual, I’m so happy with Kenny and Mark. They did a fantastic job with coating my travertine deck! It came out beautiful. I was speaking to numerous of different companies and they all just wanted to do a basic sealer on my travertine deck. Kenny educated me and told me the pros and cons of sealing travertine and coating process. Well, he knew that I didn’t want to keep sealing it every year, so he recommended me to coat the travertine that can last up to 4 to 5 years, as long a i maintain it the decking appropriately. Thank you both and if I would definitely use them again.

We had our pool deck and lanai of approximately 1,200 square feet of exotic travertine treated back in March 2018.  Although we were immediately impressed with the results, I wanted to wait to write the reviews to see how it did once the weather warmed up and we were actually using the pool and deck more.  The treatment transformed our deck from a super slippery danger zone surface to a non-slippery, safe, usable space.  I was so scared of kids and people slipping on our travertine pool deck, I would lay beach towels all over where people would walk.  If I didn’t, there was always a kid who would end up slipping. Before the treatment, I walked so gingerly and cautiously across the travertine because it was so slippery. . After the treatment, I could literally run across the deck (with it wet) and not slip.  Before we found National Sealing company online, we had ordered several products to apply ourselves.  After several attempts, we still had a very slippery deck.  Kenny was extremely professional, courteous, and easy to work with.  The treatment was expensive, but for the peace of mind and lasting results, well worth it.  The treatment also enhanced the beautiful colors in our travertine, making it look even better.

No complaints.  Delivered as promised.  Professional services and cordial.

Our pavers look alive again! The coating applied by National Sealing really makes the pavers in our driveway and around our pool area appear new.

Kenny is very professional and extremely accommodating, especially with weather situations. We happened to be out of town when the process was done but what a great sight to come home to!

We would definitely recommend National Sealing.

Kenny and his crew were very responsive and competent from the initial assessment of our needs, bid, scheduling, application and post-job follow up.  They accommodated a late PM start to minimize impact to our business and the product was as advertised – light clear grit surface that has dramatically improved slip resistance on our commercial pool deck.

Found national sealing online and after trying to figure out the best method to protect my pavers, I went with Kenny and he didn’t disappoint. So far so good.

Great service excellent finished product. An absolute pleasure to work with. Non slip surface is amazing. Kenny was great to work with.

Kenny, at National Sealing, was very helpful with explaining how important sealing our pavers was after we built a new home and were looking for a sealing company. The price was right and we were able to schedule a date for sealing that worked for both of us. They did a great job, came when scheduled, and were professional and thorough. I would highly recommend National Sealing.

Great service, product works as advertised, not my picture above but thats exactly how they were all faded out, after applying the product color came out just like in the picture, friends and family were amazed how good it looks now. Mark from his staff was wonderful and experienced he explained how the product works and how to care of it.

We had very slippery travertine around our pool deck. The deck was also a bit lighter than we wanted. The application not only completely solved the slipperiness, but it cut the glare and slightly darkened the travertine, giving it a richer look. It is so nice not to worry about people slipping, especially kids. The work was done efficiently and professionally. Very satisfied!
