How to Seal Tile Grout, Information on Sealing Grout

by | Jun 3, 2013 | Grout and Tile

National Sealing Co has developed a durable coating process to protect tile & grout. Let’s first make one thing clear – sealing tile grout is a waste of time and money. By comparison, our process is a durable, long lasting coating.

This application was an outdoor grill. The customer wanted to preserve the grout from the effects of the outdoors i.e. mildew, dirt, and grease from the food. In addition, by protecting the surface it made it easier to clean, and germ free. 

When using any sealer, the sealers penetrate the grout and cure below the surface; leaving the surface exposed. In addition, by definition, sealers are temporary. The area will have to be cleaned and then re-sealed approximately every 1.5 years. Our coating process is a multi-component process that includes hardeners. The coating cures on the top of the tile & grout, keeping the tile maintenance free while also protecting the surface of the grout.

For more information on coating grout, contact National Sealing today.

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.

Very professional and responsive. The product is as advertised and looks great while creating a non-slip surface.

We used National Sealing about 4 years ago to reduce the slippery nature of the Travertine around our pool deck and inside our outdoor Cabana. It worked great and no one slipped after the material was applied. End of June thru July 5th our grandkids were going to stay with us so we decided to reapply to ensure no accidents. Again, the product worked perfectly and the 8 and 5 year olds ran around with no slipping.
I highly recommend their product.

National Sealing Company has an awesome product that really works!! We have tried other applications to help make our travertine deck non-slip and nothing has worked. The application process was very quick and the staff is very friendly! The peace of mind of not having to worry about anyone slipping is totally worth it!! Thank you!!
Paul Sheppard
Great service on arrival. Product works as advertised. Awesome to be able to maintain my travertine and simply wipe stains off with a damp cloth.
Julie Bodie
Great job! Our pool deck is now perfect for preventing little kids from slipping! They were in and out in an hour and very responsive! Would highly recommend Kenny and team!
Jonathan Kahan
Saved my pool! Had a pool company lay down sealant without grip, which effectively made my backyard unusable. National Sealing came in and applied a new coat with grip and I got my pool back. Fair pricing and fast service. Would use again although hopefully won’t have to!
Adam Floyd
NSC sealed my travertine pool deck. Looks awesome and non-slip.

Thank you so much! We were in a tough spot where another contractor did not apply the sealer well and our driveway was continuing to get dirty with tire marks. National Sealer was able to get it all cleaned up and then apply their special coating which made all the colors pop!
Summer Farrell
Prompt, great communication and love the results, our pool deck is not as slippery with the nano bead traction layer they sealed out travertine pool deck with. Highly recommend
Peter Leiner
Easy to schedule working with Kenny. Professional and timely on appointment day. Product definitely added a texture and grip to travertine that other sealers had failed to do providing the non-slip results we were hoping for.
Jennifer Mora
Mark was our technician and he was on time and did a fantastic job. We had the nano beads covering and it was a game changer. our concrete is no longer slippery when wet and the feel of the beads under bare feet isn't rough to walk on barefoot. It gave the concrete a texture and a nice shine to the concrete. We were able to walk on it within 24 hours unlike other sealers that take days to dry. I highly recommend them.

Very professional. Nice looking job

Contracted National Sealing Co 1 year ago to seal my home’s travertine pool deck. What a great product! Prevented slippery conditions, plus helped protect stone from corrosion. Very happy with results, professionalism, knowledge and service! Company stands behind their product quality and service.

Finally!! A solution for my reused 20-year old pavers — they were completely faded and had turned bright pink from original color that clashed with the dark greys and whites we renovated the home to show. I learned from Steve who did my application that this company is like former military & commercial divers that make their own “dye” on site from lessons learned in the field. I watched him blend his chemistry magic and have been completely wowed by the results. I had done all the searching and there is nothing like this in the market. Amazing results, friendly team, and fair prices!

We found National Sealing Company online while in search of a solution to correct the slick surface of our travertine pool and lania pavers. Kenny explained the process, even connected us with a local power washing company, which is needed before the seal is applied. The results look great, the sealer makes our travertine tile look fantastic! The surface now has a bumpy feel when walked on with bare feet but so worth it to not have the worry of someone getting injured! Good experience - would recommend!

First class in every way! We had about 3600 ft.² of stamped concrete resealed with National Sealing CO’s proprietary sealant and nano beads and could not be happier! I’ve had so many comments on the great job they did and It feels so much safer to have a little grip for when my granddaughter is running around! Thank you so much!

I used National Sealing Co to seal and apply there nano beads on my travertine pool patio. I can thank them enough for a job well done. With the peace of mind having my stone patio done right! Kenny is awesome to work with.
Chip Stubbs
We have used National Sealing Co. multiple times on different properties. We are very pleased with the results and with Kenny and Mark. We will continue to refer them to our friends and family.
Jessica Brady
We found National Sealing Co a few years ago and have had them out twice now to reseal our patio and pool deck. When we originally had stamped concrete installed around our pool we did not realize how slippery it could be. The grip is much more noticeable after resealing and the concrete looks great. Scheduling and communication is easy. Really happy we found National Sealing Co and will continue using them in the future!

Exceptional service. Job done on time & well done! Excellent service from my first call with Kenneth,all the way through to the guys who completed the work. 5 stars!
Kim Webb
We've had our coating down for several weeks now. So far, we are thrilled. Kenny has been very responsive and answered all our questions. Highly recommended.

I reviewed the information online about National Sealing and reviews from others. Everything was very positive, and the anti-slip product was what I was looking for. A bit nervous on doing business with an out of state company but Kenny was great to work with. He provided me with answers to my questions, took a deposit and setup a date. Mark arrived on the scheduled day and did a great job. I'm very satisfied with the entire process and looking forward to getting some good years in with this product.

A company that actually shows up on time and does what they say.
Can't speak for the produce yet, as is was just applied, but so far so good!
Marco Suarez
Ken did a fantastic job explaining the products they offer to include the five warranty on their proprietary sealing products. We selected their top of line no slip sealer for our new pool deck. After we scheduled are appointment, Ashton came to clean the deck followed by Mark the next day to apply the sealer. Mark took his time to explain the process and reiterated their warranty on the product should anything happen. The sealer gave our new pool decking a beautiful sheen. It does take 24 to 48 hours for the product to properly cure. So, be patient. We’re super happy with the results!

Had them come out and Nano coat my new Pool area and it looks great. I would tell you to go with them and you cant go wrong.

Kenny is incredibly knowledgeable and National Sealing was very professional about everything. They showed up early, which in Miami damn near never happens! Also love that they back they're work with a warranty. Would highly recommend them.

Mark came out and was super friendly, experienced, and explained how their process works. Kenny scheduled us and got us on the schedule relatively quick with only a few weeks notice. Glad I found them as I was tempted to seal our travertine pool decking myself and it most likely would have been a disaster. Will see how this coating hold up but with the Nano-Bead nonslip coating, Kenny anticipated 4-5 years even in our Houston heat. Pleasure to do business with.

Had this done at my house on pool deck and on concrete slab of tiki hut at my river condo as guests were slipping. Fellow owner at river yesterday (preparing for Helene) commented that this stuff is legit.

Installed Travertine Pool Deck and found out how slippery it was when it got wet. It was near impossible to walk on without slipping. I found National Sealing Company's videos on Youtube and was very impressed with their process. I contacted them and spoke to Kenny. They applied a sealant and a non-slip surface on our travertine. It has been a difference maker. We are extremely pleased with the customer service and the final product

The product they coated my travertine pavers which made them pop like a million bucks! The installer, Martell, was extremely polite and did an absolutely splendid job and protected areas before applying the coating. We have not yet tested the non-slip coating after getting out of the pool, but it's very similar to a medium-grit sandpaper so I have no doubt that it will not be slippery at all. I cannot recommend this company any more highly; I would give them 6 stars if Google would let me. Thanks to Kenny for answering my plethora of emails to calm any fears I may have about their process and their product.

I tried several products in an attempt to reduce the slipperiness of the travertine around my pool. None of them worked. I continued doing research and found Kenny at National Sealing. I was very skeptical of trying another product but, Kenny answered all my questions and made me feel very comfortable. I am so glad I took a chance on his product. Not only did it solve my slipping issue, it also made my travertine look new. Mark did the application and once again answered all my questions. He did a great job. No runs and no spots that look different. I am very pleased.

We used National Sealing recently to seal our Turkish shell stone pool deck, which had become very slippery when wet (dangerous for everyone, especially young kids). We opted for their proprietary non-slip bead application, which ended up being the right choice. The product was applied in a matter of hours, dried by the evening, and we were back to using our pool the next day. It did not change the appearance of the stone in any noticeable way, and has the perfect amount of grip without being too rough on the feet. Looking forward to the expected 4-5 year life as well. Kenny in the office and the applicator team were all responsive and professional/knowledgable. Would recommend them to anyone having slippery surface issues on their pool decks.
