Ask a Question
  • Is this water based?

    No.  The Diamond Clear we offer is colvent based.  For a water based product, you can use Super Diamond Clear VOX.  

  • what is the tempeture range for application of the concrete sealer

    Surface and ambient temperature during applications should be between 40°F and 90°F (4°C and 32°C).  Sealer temperature should be at least 50 degrees F.

  • The diamond clear concrete sealer description suggests it comes in either a "natural" or matte finish. Is it truly a matte finish? One of the questions below suggests this is not the case. Everywhere else I've looked (including the Euclid diamond clear website) this product is described as having a glossy finish. I really don't want glossy! THANKS

    In our experience, i would not qualify diamond clear as a "gloss" finish.  Super Diamond Clear, on the other hand, is definitely glossy.  So while diamond clear may impart a sheen, in our eyes, it is not glossy.

  • is there any money back guarantee for this product?? We just purchased and applied and are VERY unhappy with the results

    There are many variables with the application process of any sealer, so there is not a money back guarantee.  However, if you would like to contact us, we would be happy discuss your application and what issues you are having. Also, we don't have record of an order under your name so please include your order number so we can find that information.

  • Does the Diamond concrete sealer come in different finishes? Like matte? If so, does it still stop the color from fading? I'm not a fan of a gloss look on my patio.

    Diamond clear only comes in the one finish.  It does keep the color from fading

  • What is the coverage per gallon for concrete

    Coverage NOTE: Coverage rates are approximate. Actual coverage depends on temperature, texture, and substrate porosity. Avoid excessive build-up of sealer, as this may cause discoloration and/or poor product performance.
    Application ft2 /gal (m2 /L)
    Curing & Sealing Fresh Concrete  
    First Coat 300 to 350 (7.4 to 8.6)
    Second Coat (Optional) 350 to 400 (8.6 to 9.8) 

    Sealing or Re-sealing Existing/Cured Concrete 
    First Coat 300 to 350 (7.4 to 8.6)
    Second Coat (Optional) 350 to 400 (8.6 to 9.8)

  • Does diamond clear protect concrete from oil stains and salt

    You best bet for protection against salt and oil would be Ghostshield Siloxa-Tek 8510 

    Diamond clear isn't the penetrating sealer like you would normally use for salt and oil protection.

  • How much concrete sealer does 5 gallons cover?

    Coverage ft2 /gal (m2 /L) First Coat Second Coat (Optional) Curing & Sealing Fresh Concrete 300 to 350 (7.4 to 8.6) 350 to 400 (8.6 to 9.8)
    Sealing or Re-sealing Existing/Cured Concrete 350 to 400 (8.6 to 9.8) 350 to 400 (8.6 to 9.8)

  • Does this sealer feel slippery if walked on when wet? I've used sealers before that made the concrete a lot more slippery after a rain

    The concrete will be come a bit more slippery when wet with this product, however there is  a additive you can mix in to combat that.

    This will mix directly in the sealer and take care of the issue.

  • Will this restore the color to my stamoed concrete? My concrete color looks great when wet, but faded when dry.

    For a gloss sealer for stamped concrete, i would reccomend Super Diamond Clear (

    Alternatively, if you want a higher gloss, wet look sealer, i would say Ghostshield Cryli-Tek 8505 (

    Prior to application, make sure to prep your concrete fo the best results.
