Seal n Lock Paver Sealer Review 2.5/5 (6)

Seal n Lock Paver Sealer

Seal n Lock Paver Sealer

Seal n Lock Super Wet is a high solids, two-part water based pure urethane sealer that penetrates the pavers to provide a longer lasting protective barrier with superior joint stabilization (no need for polymeric sand) resulting in a ‘wet look.’ Super Wet is user-friendly and environmentally safe. The high solids content of pure urethane wears evenly and lasts longer than solvent based sealers. Super Wet is available in 2 and 5 gallon kits.

The first all in one day process!

Seal n Lock Paver Sealer Scores (1-10)

Wet Look: 6

– Considering this is the Seal n Lock wet look version, the sealer did a very average job at enhancing or improving the paver stones with a wet look.

Gloss Level: 6

– Same as the wet look, The Seal N Lock did have an average shine after drying. This product goes on milky white but dries to a clear satin shine.

Joint Sand Hardening: 9

– The Seal n Lock did an excellent job with hardening the sand down to the base of the pavers. After 2 years, the sand erosion was minimal.

Fading/Wearing After 2 Years: 2

– After two years the Seal N Lock Wet Look has faded significantly. Very to little if any of the shine or wet look was visible. There was a large amount of mold and mildew growing in the sand as well.

White Haze/Yellowing: 10

– Seal n Lock did not yellow or turn white.

Overall Score Seal n Lock Paver Sealer at 2 Year Period: 6.6

– Seal n Lock did not score very well for us. We definitely did not like the one day application process. We had all kinds of trouble with the “wet sand” application even though we watched their video and talked to the customer service. We could not get the sand even and had air pockets. After many hours we did get the sand even and level but in our opinion, we would prefer to let the pavers dry and sweep in the sand. We also noticed the the sealer seemed to feed mold growth in the sand. After checking with some contractors, we have found that this has been a known issue with Seal n Lock.

Does not discolor, great at sand hardening, everything was average or poor.

        Nancy, couple of things:

        1. We do not allow manufacturers to post
        2. We agree with you on the previous commentator. We did not catch the fake name.
        3. To be fair we have edited out both comments.

        We only allow comments that are real and honest from customers who have used the product. If we notice anymore fake comments (good or bad reviews) we will lock this thread.

          How long does it take for a post that a contractor writes to actually appear on this site?

          • Concrete Sealer Help says:

            Mary, asking your customers to post endorsements is trying to manipulate this page. I said it had to be \”real\” comments. I do not consider these to be \”real\” as you are influencing them to post. We had no comments on this review for months then all of a sudden we get numerous within a few days. Very fishy…

            Please refrain from this and posting future comments.

  1. My company "Brick Paving Systems,Inc." has been installing pavers in the Tampa Bay area for 35 years and we have used many products to seal them over the years.We have used solvent based as well as water based sealers and I would rate Seal and Lock Wet Look as one of the best. The product needs to be applied correctly or you will not get the best result.Recently the product was reformulated and more of the pure urethane added and our customers are extremely happy with the sealing jobs. Wet sanding takes practice and dry sanding is used when we do pool decks with screen enclosures.The key to a great job is applying the flood coat to make sure the sealer penetrates the joints,then apply a fine coat for consistency..The end result is a nice color enhancement,not a heavy glossy look that makes the pavers look unnatural. You also need to use the right equipment to apply the product, a pump up sprayer will not give the same result as an airless or Seal and Lock's sealer application unit.This is a great product and I highly recommend its use and we find the service department and customer service at Seal and Lock to be very professional and an asset to the concrete paving industry.

    We have come to the conclusion that due to the fact that we were not part of any of the testing, the allowance of a fake testimony by a fake and offensive name, the disrespect and assumptions made on your part via your last post without discussing with us, and the negative comment ending your post, we respectfully withdraw our company from this website. The sad part of this website, is that it is simply a marketing tool…each time someone clicks on a place to order, the company that comes up gets to share some monetary profit with you. It's an old marketing tool and alot of people don't know that….but when the tone becomes negative and offensive, then we want no part of it.
    The contractors that did decide to write in to this page, sent us a copy. We find that these are very professional and respected individuals in the industry who wrote real and honest reviews. And we receive great reports from their customers. Collectively, a decision was made by all today and after receiving legal counsel, we are requesting that you remove our company and all comments from this site. If you do not, we will report you to the Federal Trade Commission and seek further legal avenues.

    • Concrete Sealer Help says:

      Mary, we as in anyone have a right to write reviews of products we have used as consumers, just look at Amazon. We tried your product and had some issues that are valid. We would have allowed your contractors reviews if they would have came over time but it was obvious you asked them to write reviews and that is wrong in our opinion. As for your other assumptions, you are wrong.

      • Tyler says:

        This is just seal n locks scare tactic. They do it to contractors that stop using their product as well. IWork for a ckmpanynow thatused to use real n Lock (over 2 million square feet Rach year) and had to stop because it's poor durability. Once our company transitioned to a new product – the owner, Richard Colletti, sent threatening messages to him, left him bad 1 star re views on line and even filed a BBB complaint. had an attorney draft a cease & desist letter to him as well. My boss. (the company owner) submitted it to his attorney who laughed and said they didn't have a leg to stand on and it's just a scare tactic.
        There's a class action law suit going on against Seal N Lock right now.
        Mary Elizabeth Smith made a group email with a bunch of contractors (even the owner of the company I work for now) with a link to this page asking everyone to counter this page with positive comments on deal n Lock and will give their next bucket of sealer for free. Notice all the comments all came in around the same time.
        That compamy, seal n lock, is a joke… Owned by a guy that got thrown out of the navy because of insubordination.

    Seal N Lock turned my gray pavers to charcoal black and brown. It absolutely destroyed a $70,000 project. Does anyone know how to get this stuff off? Never again…

  4. Scott Amendolaro says:

    I used Seal N lock 3 years ago to seal the driveways and patios of my 2 homes
    My main driveways for both homes amounted to over 6000sf. The deep enhancement and shine lasts less then a year but the Joint sealing is supurb which is the main reason for me sealing them. 95% of my joint sand stayed intact . I am now starting to see weed and insect intrusion in random areas. I have also noticed that most of the joints have now turned (or begun to turn) black with mold.

  5. Scott Amendolaro says:

    My back patios I have had some mixed results

    On one Patio I have 2,500 sf of artistic paves . Artistic pavers are extremely dense have practically no absorption. It does not take much to coat them and it can result in a slippery condition. Because of the low absorption a blower is required to stop pooling .. Long term I have had my artistic pavers turn white after the first year in areas where people enter and leave the pool areas . It is definitely the sealer since I can pull it off with my fingers after pressure washing. I suspect that the salt water from the pool is getting under the sealer since it does not absorb well into artistic pavers then drying and turning them white. I do plan on resealing the back with sealnlock again but I would caution anyone using it on artistic pavers around salt water pools that you may want to leave your pavers unsealed. But in the areas not exposed to salt water the shine and enhancement lasted for over 2 years.

  6. Scott Amendolaro says:

    On my other patio which was much smaller I had an overlay of 2" pavers (over Chattahoochee) . These had been sealed in the past with solvent and I had a lot of mold growth in the joints because the pavers did not have great drainage .( I do not recommend using overlays if you can avoid it) I aslo do not recommend Super wet for overlays if you already have mold issues . I have had mold growth both in the joints and on the pavers themselves.

    I am going to give the Natural Luster a try next time ( which I knew would resist mold) I used superwet because i wanted the enhancement.

    I am about to reseal them both again and My sister just got pavers as well so I will be using sealnlock again.

    • Scott Amendolaro says:


      Decided I would try the DEFY water based product. Received a sample and ran it on several pavers and it looks good .
      Looking at the Scores here it will not fade as quickly as the Seal_n_lock and I don't need to mix it so thats a + Only time will tell now, I plan on doing several homes with the Defy and compare it to the Seal_n_lock

    • Chris says:

      Bob, You don't have a clue about sealing or sealers! I have over 30 + years in the Interlocking Paver Industry and have used every type of sealer under the sun.
      Seal-N-Lock is not over priced it is very fair taking into account you add water when mixing so you actually get 10 gallons out of a 5 gallon bucket. Why don't you go to Home Depot and buy some garbage they sell and compare.
      You have to mix it and apply it right like anything to get it to work correctly.
      I think it is a great product and have had great results with it!

    • Tim says:

      You got it right Bob. Seal N Lock discolored my pavers and they looked dingy after the application. The end of my driveway slopes down to the road. If it rained during the first year, my car skid when I hit the brake before the road… making it down-right dangerous. Seal N Lock is garbage. The wet sanding lasted about a year.

      • Nick Smith says:

        As a contractor – I used real n Lock for years. However there are my h better products out there and we had to stop using the sealer because it would fail after only 6-9 months.
        We now use Ure-Seal h2o and it works wonders.

  8. Bill says:

    I just received an estimate for washing and sealing my brick pavers. The company states that they apply 3 coats of Seal n Lock instead of the typical 1 heavy coat and a second light coat. They claim this provides better results in the wet look as well as the gloss. they also claim this 3 heavy coat application extend the life of the sealer to about 3 years. What do you think?

    • Concrete Sealer Help says:

      Doubt it. More is not always better and does not mean it will last longer. It may give a richer wet look though.

    • Tim says:

      During rain plan on the surface being extremely slippery and dangerous. If used on a driveway, your cars could skid and slide.

  9. Ed Gaudet says:

    After 3 coats of seal n lock, I put on an additiona 2 coats of the wet seal n lock. I did not get the wet look that I expected.
    The first 3 coats were put on by a company call Dura Lock, which I would not recommend.

  10. Greg says:

    I had the low gloss product with 2 coats with surfaces well prepared for the resealing/sanding application to my driveway, walkway, lanai, pool deck brick red pavers.I had it done by a very experienced and reputable company so cannot comment on application difficulty. It dried fine and did not discolor or damage pavers. Seem average or below average in terms of durability and sand retention. Sand didn't last a year and sealer less than 2 years Very expensive and ties area up for a few days so irritating to need it redone every two years. . I am due for a resealing and will research to see if there is a better product available.

    • rick detrio says:

      How was the sealer applied? with a low cost air pump back pack sprayer? or a motorized sealer sprayer designed to spray sealer? maybe it wasn't applied with a Flood coat first and then 2 more coats after.

  11. John W says:

    We hired a "certified contractor" of the seal n lock system to seal the pavers on our pool deck. They pressure washed, sanded, swept and then sealed the pavers as the sun was setting and assured me that sealing that late in the day without the sun to help dry the product was one of the great things about seal n lock. The next morning the product had pooled in the paver joints and cured a bright, almost florescent white color … it was absolutely terrible. I reached out to the owner of seal n lock who is based 20 minutes from my home and requested he come and take a look… he wouldn't. He advised the excess product should have been blown off with a leaf blower and advised the product works much better with the sun to help dry/cure it. The certified contractor spent the next 3 days power washing this stuff off the pavers, blew out most of the sand under the pavers, blew some of the sealant onto our sliding glass patio doors ruining them and then they left. This product from our experience is terrible, the customer service is terrible and I 'd highly recommend pursing another company and product to seal your pavers.

    • Richard Detrio says:

      if to much sealer is applied, the contractor is at fault not the product. The contractor should have used a blower to move the excess sealer around so it wouldn't pool. Sounds like an application error. I have used this product daily for years. Any sealer applied like this would produce the same results.

    • bryancannon says:

      You probably chose the lowest the price. That contractor did what he probably does on every job. Homework has to be done when choosing a contractor. If your new roof leaks, is the shingles' fault or the nails' fault – most likely now. We see this every day – 99 times out of 100 the contractor was chosen as the low bid. There is plenty of ways now a days to be able to do research on a contractor.

      Did you get this fixed yet? I would be willing to try to help if needed.

  12. bryancannon says:

    We have used this product for over 9 years exclusively in our sealing business. We have never had the issues stated here. Just like anything else – the applicator must know what they are doing. There is more to sealing than just spraying or rolling a sealer onto a surface. Like one of the comments from a "contractor" that it takes 8 hours to wet sand 1000 sq ft. We routinely wet sand that same amount in about 30 minutes with perfect coverage. Again, its about learning the trade not just popping a top on a pail of sealer. Each paver is different, thus the amount and method of application of any sealer must be customized to the scope of the job/project. To use a product as a weekend warrior or a contractor on 2 jobs is useless for the basis of leaving a creditable review. I use several different types of sealers and I would never use a product on a client's property unless I have tested it for at least a year at my facility or a test location. Seal n lock does exactly what it says it does and our several million sq ft over the years can attest to it.

  13. Jeff says:

    This review above is based on their original formula. They reformulated in Dec 2015 with a 'higher solids' content. However the higher solids Seal N Lock now purchase is from overseas is poor in quality. The sealer lasts no longer than 9 months in any application.
    Dozzens of contractors have stopped using this prodict because of premature product failures.
    When contractors contact Deal n Lock owner, Richard Colletti, he tells them they 'must have mixed it wrong'.
    There is a contractor driven class action lawsuit pending against Seal N Lock System Corp because of these premature product failures.
