Super Diamond Clear Sealer Review2.5/5(4)

Super Diamond Clear

Super Diamond Clear

SUPER DIAMOND CLEAR is a solvent based curing and sealing compound specially designed to cure new concrete, assuring proper cement hydration and strength gain, while providing a non-yellowing seal to protect and enhance the appearance of concrete.

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.

    Minnesota
    Horizontal
    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.
