: grind before

: grind after

While cleaning a concrete surface is common before our sealing, coloring, or coating applications, grinding concrete is often necessary.

Removing trip hazards from pedestrian walkways is not only wise to prevent litigation, but also required by Federal Law.

This scenario was an approximate 1.5 lip in a pedestrian walkway. The lip had to be ground before a traffic coating was applied.

Grinding cement in this case created a smooth profile. Therefore, in combination with our traffic coating, we added a very coarse non-slip media to the surface to provide additional slip resistance.

National Sealing sealed our patio about a year ago and did a great job. I decided to hire them to come out and clean it this time to be sure we didn't damage the sealant they put on by using wrong cleaning supplies or methods. They did a great job. They were pleasant to deal with and very efficient and got the driveway and back patio looking brand new again while not damaging the sealant that is protecting it. Thanks for the good work.

Kenny was very responsive. He clearly explained our options. The costs seemed reasonable. They were available to do the job within a couple of days. The crew showed up right on time. The final outcome is great! Our pool deck has never looked better and is now non-slip and much easier to maintain. We couldn’t be happier with the service.

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.

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!

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.

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!!

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!

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!

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

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.

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.

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!

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.

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!

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!

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!

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.
