Update 2024 for Super Diamond Clear Sealer

As of 2024, we have found that the Super Diamond Clear Sealer has shown decent results on Stamped Concrete, Brick Pavers, and other Decorative Concrete Surfaces but does have a tendency to turn white from the UV rays. If you have any questions on the Super Diamond Clear Sealer product, please ask below in our Q&A area. We are here to help!


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. The 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

– It 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.

It’s a precast and light gray so I’m not concerned about blotchiness. I read that product can be cloudy or white on stamped concrete. My question is if it will be slippery when it rains

My super Diamond clear was applied as per instructions. Sprayed and back rolled using proper amount 2 coats. It seamed to dry normally. I had to wait 2 days to apply 2nd coat due to showers. Both coats were applied with temps high 60s and dry. But heat wave hit mid 90s and pool deck extremely sticky! Early morning not as much but still somewhat sticky. What’s going on? What can I do to solve this issue?

What product do I use to reseal my exposed aggregate concrete? It’s 3 years old and want to refresh it. It’s not as dark as it was before. Thank you.

I have white blotch spots on my multi-color (Increte) stamped concrete patio after sealing with diamond clear. Additionally, due due high UV I need to seal the patio yearly. Are these spots old sealer build-up,or issues where the release agent has unadhered from the concrete? Aside from soda blasting what is the best method to remove the old sealer and fully strip? Lastly, the patio looks great when it rains, what sealer can I use to mirror a wet look, and should that sealer be water based?

I currently have Eulid’s Super Diamond Clear on my stamped concrete patio. When the concrete was originally poured a color additive (adobe brown) was used. Removal and recoating is needed but I’m concerned the removal chemical will discolor the brown tint in the concrete. Suggested removal chemicals are Euclid Solvent, Xylene, Xylol and MEK. Do you have a recommendation of which to use or is there a suggestion of another removal chemical you have experience. I’m concerned about discoloring the tinted concrete. Attached is a photo. There is not much left of the sealer. Primarily where chairs normally located. Attached… Read more »

I use Super Diamond Clear on our driveway and there is a very noticeable color variation. I applied a heavy coat with a roller. I believe I should have put a much thinner coat. Also we have heavy lime and iron content in our water. Would the color variation of the sealer be a result of this? What else could possibly cause the various of color? The driveway is stamped concrete with a brown tint. I’ve included a picture. Thanks.

I have a new concrete shop floor with sawed expansion joints. The joints are about1/16 wide and 3/4 deep. I’ve been told to fill joint with a silicone caulk, but the joint is pretty small. Should I let the joint fill with sealer instead?

I have used diamond seal 750 on my pool deck since the original installation at the recommendation of my contractor 3 years ago. The deck is a dark brown stamped finish and it has been a battle maintaining the wet, clean look. Am I using the wrong product? Fresh coat was applied in April when we had a warm spell for 2 weeks and it looks like it was never done! 😡 HELP!!!!

I have used Super Diamond Clear as a sealer on my driveway through the years. The store where I purchased 5 gallon drums was discontinuing the sale of this product so I purchased their remaining stock and have stored the drums in my basement away from excessive heat or cold. I have 2 drums remaining that have never been opened but noticed that the it states on the lid “to be used by 8/17”. Can I still use these 2 drums or should they be disposed?

I have applied Diamond Clear in the past to my driveway and wonder if I could try another solvent-based brand or if I have to keep using this one? Your rating gives it a 7.5….looking for something with a higher rating overall – just curious if I can a few more years in-between applications. At this point, I am resealing every 2-3 years. Also, I really like the effect of the brown tint on the exposed aggregate driveway – if you agree that I can use another brand of a solvent-based product without adherence issues – which one is highest-rated… Read more »

We have a pool deck where I a putting down Super Diamond Clear every year as our pool is out in 90 to 100 degree whether in the summer. We were told to do this by the contractor who initially stained and sealed our deck. Where we might have a rug on the deck, the sealant stays fresh, but where the sun hits it, it needs refreshed every year. Am I using the wrong sealant? We would like not have to do this every. Any suggestion?

We have used Superior Diamond Clear Coat before at our previous home where we had “omni stone” around our pool. The stone was a deep red color . It worked fine. So now we decided to use it at our new home on our very large concrete driveway and it looks like someone smeared dog poop all over the concrete.. It is blotchy and shows roller lines. I guess we will need to use concrete sealer stripper and I will NEVER use Clear Coat 350 again! at $200+ for a 5 gallon can.

I have the same white ghosting as others listed below. What product can I use to strip it off and then reseal with another product?

Also I have an automatic pool cover and every time I close the pool the cover sticks to the concrete. I have to physically pull it off the concrete before the motor can roll the cover up. Any suggestions on how to unstick it?

Thanks. I was just looking over the stamped concrete and it does have some fairly deep impressions. If rolled, do I need to put extra product on to cover the crevices completely? or brush in?

The stamped concrete used to have a gray over-color in parts. That is gone. Is there something we can use to simulate that – with or before – sealing?

I apologize if this question went through already, but my concrete used to be two toned. It only has its base color now (the gray is gone). Is there something that I can apply before or during sealing that would give it that two toned dimension again?
