Super Diamond Clear Sealer Scores (1-10)

Wet Look: 9

– We were very impressed with the Super Diamond Clear darkening/enhancing the stamped concrete patio. Overall look and colors were enhanced well.

Gloss Level: 8

– Super Diamond clear contains 25% solids according to the manufacturer. This sealer left a nice semi-gloss shine to the stamped concrete patio. We did notice that the Diamond Clear looked stunning when dried.

Joint Sand Hardening: n/a

– Does not apply as we used the Diamond Clear on a Stamped Concrete Patio that contained no jointing sand.

Fading/wearing After 2 Years: 7

– The Diamond Clear did fairly well with fading after 2 years and was on par with other solvent based sealers containing similar amounts of acrylic. There was not visible wearing or peeling.

White Haze/Yellowing: 6

– We were not impressed with the Diamond Clear when it came to the dreaded white haze. It did not turn white completely but it definitely left a light white look to the sealer and patio.

Overall Score Super Diamond Clear at 2 Year Period: 7.5

– Overall the Super Diamond Clear did well except with the white hazing. We were very impressed with the appearance after application and it did seem to hold up fairly well through the years.

Not a bad sealer but not the best either.

    Live in Dallas Texas and had an aggregate pool deck poured, what is the best sealer to use giving a wet look? Will i need to add an anti slip agent being that it is aggregate? Is it easy enough for me to do myself.

    • Concrete Sealer Help says:

      Michael, I would look at the SuperSeal 30 and adding a ant slip will help with the pool area. Yes you can easily do it yourself.

  2. Dan H. says:

    Wet look, darkening, satin/semi-gloss
    Color impregnated brushed concrete pool deck
    Contractor sealed with Diamond Clear upon curing and again at 3 yrs. Now 3 yrs later (6 yrs ttl) need to seal again. Diamond Clear looks/performs great for 2 yrs only. At 3 it is basically gone. What will last/perform longer in Minnesota?

  3. C W D says:

    I just receintly poored a new floor in my garage and sealed it with two coats of Super Diamond Clear and was wondering about using an anti-slip agent. It seems like this shouldn't be an issue I was just wondering what would be the best way to go about applying this? I've heard I will have to loosen it up a little with xylene.

  4. Chris says:

    I get bubbles up from the concrete every year so I have to put on a new coat every spring. Looks beautiful though.

  5. sue says:

    I had my stampcrete porch sealed and there are white areas that came up right after it was dried. Also a concrete repair was done the day before on the concrete porch and it was also sealed the day after the work was completed. It was power washed and sealed the same day. Was it done properly? I have pictures also.

    • Concrete Sealer Help says:

      Not sure. It could be trapped moisture under the sealer. Try applying xylene solvent to those areas to restore the look.

  6. Bob k says:

    Can I apply VCR tile on top of super diamond clear sealed?

  7. Patria L says:

    Guys staining deck above exposed aggregate concrete dripped stain on the patio. The patio is sealed with super diamond clear and they tried to clean it up by using paint thinner and a wire brush…now I have patches that are a dull white color in several places on my patio. The deck guys said they contacted the super clear folks and they said just to clean and re-seal those areas… should I trust this or does anyone think this doesn't sound right? Thanks for any advice here…

  8. Jeff says:

    What type of anti slip product would you use?

  9. Tim says:

    What is the best time of day and temperature to apply the super Diamond Clear 350 concrete sealer.
    I applied it on a hot day around 11:00 am in brite sunshine. The patio was very hot. The sealer didn't bubble right away but the next morning almost the entire 950 sq ft patio was full of small blister bubbles. What can I do to fix the patio now?

    • Concrete Sealer Help says:

      Apply on a cloudy day late in the evening. Spray down the patio with xylene to melt the bubbles. Do not apply this in direct sunlight to avoid it repeating again.

  10. dino says:

    how can I remove the sealer

    • dino says:

      the person who did my concrete mixed colour with the sealer and know it's peeling and looks terrible how can I remove it

  11. marlene says:

    Is this product safe to use in house?

  12. marlene says:

    It has been over a week and still has a "horrible, strong, nasty " oder. If a pillow or towel is on the floor, it picks up the floor smell.
    It's been a major disappointment with this product. The finish scuffs and marks easily. Any suggestions on how to elimante the smell and how to deal with the scuffs and scratches?

    • Concrete Sealer Help says:

      Ddi you use this inside? You should not have due to the odor. It will have to go away naturally. Not sure on the scratches.

  13. Alyssa says:

    Can you burnish Super Diamond Clear Sealer?

  14. Kevin in Ohio says:

    I have 1500 sq ft of stamped concrete. I have been coating yearly with super diamond clear for 7 yrs. Good results but have to do it every year. A concrete guy said I could cut / thin the diamond clear with zylene and it might make it more durable, last longer. Sound true?

  15. Joe says:

    I had a stamped concrete patio poured last year and it turned out beautiful. It was sealed with Super Diamond Clear and seems to have held up pretty well. However, it is on the south side of the house and gets full sun all day long. I was going to reseal it again this fall just to keep it looking its best. If I want to switch from Super Diamond Clear to SuperSeal 25 or SuperSeal 30 this time around, do I need to do anything special to prep the patio, or is a good pressure washing sufficient?

    Also, is there any big advantage to using the Superseal 30 vs the 25? Thank you!

    • Concrete Sealer Help says:

      The 30 is a little shinier then the 25. Just make sure the surface is clean and that the Diamond clear has not discolored.

  16. Harry behnke says:

    i sealed my aggregate patio two years ago , shine only held up one year ..was told by several people diamond was the best , i do no believe this ..i am now searching for another brand dealer ..i would think any of them would last a year and less expensive.

  17. Matt says:

    Have used it with a brush every year since 2007 on my stamped patio. Great wet look. Easy to use. No fading on discoloration. But it does NOT last more than a year. I would give it an 8. Would consider a rival product if it would last longer.

  18. Mike says:

    i sealed my stamped concrete patio and there are areas where the sealer took well and areas that it did not. It almost looks as if the areas of high foot traffic did not take the sealer or it did not make the colors pop. I have only put one coat on the patio. I would love to get some advice on how to get the color back jn those areas?

    • Concrete Sealer Help says:

      Most likely it is the stamped concrete itself that is causing this, not the sealer. Not sure if it can be fixed. Might want to contact a local pro who can look at the project for some advice.

  19. John says:

    We were sold Euclid diamond clear 350 which turned dark we were supposed to have clear. How can we either remove or at least lighten our concret driveway?

    • Concrete Sealer Help says:

      It is normal to darken the color with these products. To remove you will need a concrete sealer stripper and a pressure washer. We use the Clemons Concrete Sealer Stripper.

  20. Carol says:

    I would like to seal my pavers with a matte finish. What is the best product to use. Can I roller it on? Thanks for your help.

  21. LSP says:

    Will rain impact sealant drying if applied to pavers for just over an hour? Was told it took several hours for second coat to dry.

  22. Pat Harrison says:

    Can you put an epoxy concrete paint on it?

  23. Justin says:

    Okay so I'm in a terrible situation with this product. I took a job to reseal a pool deck. I cleaned it. Sprayed the surface with xzylene and rolled the sealer on. I did wait until the slab was completely dry before I applied. While the sealer was still wet the homeowners lawn maintenance guys mowed the yard and got grass all over the fresh seal. The homeowner used a blower on it to try and get all of the grass out and after hours of that and also picking it out the seal turned white in a few spots but also bubbled up everywhere. This is the first time I've ever used this product and had this happen. I've used this seal 100 different times at least and never had this happen. So at my cost because the homeowner blamed me entirely I scraped bubbles and xzylened until there werected no more bubbles. This time I sprayed the seal on. The front walk turned out perfect but the back around the pool bubbled up again, only this time worse. I don't understand what's happening. Please help.

  24. Joe says:

    Can this product be used on a wood table.

  25. R. Mazurek says:

    I have used this product for many years. Every year requires another application because the exposed aggregate surface becomes discolored as though a light coating of light brownish mud covers the entire surface that was coated with Super Diamond Clear. "If" a portion of the coated surface is continuously cover with something such as a rug, the Diamond Coat remains clear and continues to enhance the natural appearance of the exposed aggregate.
    From my experience using Diamond Coat at my home, many years ago, I can attest to the fact that the Diamond Coat back then did not turn to a muddy appearance.
    I invite any feedback. I am hesitant about paying $100+, again, for a 5 gallon bucket of this product.

  26. Drew says:

    I have been sealing my patio with Super Diamond Clear. This past April it didn't take so well. I think i might have applied it too thick. How much time needs to pass before applying another coat?

    • Concrete Sealer Help says:

      Most likely you need to strip and start over. It does not just go away and adding more later one will compound the issue of build up and too many coats.

  27. Daniel Donohue says:

    Hi, I just applied an acid stain to my concrete basement floor and looking to finish it off with a sealer. After investing so much time on the stain I really want to find a sealer that makes the color pop and give me a nice wet look. Since it's indoors I have to use a water base product. Will Super Diamond Clear whiten/cloud if it's indoors or is this because of the sun? In the review above you say that Super Diamond clear is not the best sealer. Can you recommend a better sealer for my use case? Thanks!

    • Concrete Sealer Help says:

      Diamond Clear is solvent based, not water based. Look at Masonry Saver Decorative Concrete Sealer.

      • Daniel Donohue says:

        What about Super Diamond Clear VOX. Have you used this product? The product brochure says it's non-yellowing and 25% solids. Would you choose the Masonry Saver over the Super Diamond VOX in terms of wet look? Thanks
