    • Can this product be used to seal a below grade foundation?

      We would not reccomend using this product for sealing below grade.  This is a sealer for decorative concrete giving a gloss finish. For basement walls, i would suggest Lithi-Tek 9500 (  

      For a true foundation sealer, contact us by phone or email for a quote on Tamoseal Foundation Coating (

    • I'm looking for Euclid Diamond clear coat "350". Do you carry this particular grade? If so what would the price per 5 gal be for approximately "10" 5gal buckets? Total 50 gallons.

      Give us a call or send us an email and we can set you up with a custom quote for 10 pails of Diamond Clear 350.  We need a bit more information to get you a quote.


    • Can this be used inside of a house on a basement floor? Is this product low VOC? Thank you.

      This can be used inside, however it is not a low VOC product.  It will definitely have a strong odor.  Check out the Super Diamond Clear VOX for low VOC

    • Can you use this on a stone wall?

      Depends on the type of stone. Please give us a call and we can figure out if it will work for you!

    • Is this oil base with high solids


    • First aid treatment for dogs feet saturated with super diamond clear.

      Contact your vet. If the dog hasn't ingested it, you are probably ok, but their feet will be sticky and don't want to have their paws stuck to the floor /ground.

    • What is the cleaning process

      In most cases, a good power washing is good enough to get the contaminants off the surface.  In some cases, you will need to use a stripping solution.

    • What sprayer do you recommend to apply Super Diamond Clear. Cheap sprayers don’t work.

      A metal concrete sprayer, like a Chapin 1949

    • where is Super Diamond Clear available in Ohio or West Virginia?

      Due to VOC restrictions imposed in Ohio, super diamond clear is not availabile there.  We can however ship to West Virginia.

    • I placed Super Diamond Clear on my large new exposed agg patio 2 years ago. We get heavy snow and cold in northern Idaho. Is it too soon to give it a second coat? I also plan to put a hot tube on one end of the patio and thought it would be good to give it another coat before I place the tub? Also, now long does it take to ship to me in Idaho zip 83858? Thx

      You can definitely apply another coat, just need to make sure it is clean so the coat will adhere to the existing. It also definitely wouldn't hurt to put a coat down before your hot tub goes in. 
      A pail will take about 3 days to get there.

    • where can I buy Super Diamond

      You can buy it on our website, just click add to cart and go through the checkout process.

    • Can you tint this sealer?

      Absolutely. Check out the Universal Color Packets

    • Can I still seal concrete that was poured a year ago?

      Absolutely.  Make sure it is clean and dry , and you're good to go!

    • Can the sealer be applied by a roller?

      Yes.  We reccomend a 3/8" nap, solvent resistant roller.    

    • How long does it last typically, how often do u need to reapply it?

      The answer to that depends on a few things  What is it being used on, what kind of traffic it sees  and what kind of elements it is exposed to.  In short , we recommend resealing each year for most exterior applications  

    • I had someone put this on my driveway but now it looks like swirls and he did not powerwash before. What can I do? The concrete looked great before but we wanted to make sure it kept it that way. Now I am upset with the outcome.

      How did they apply that they got swirls?

      You can re-liquefy the sealer with solv-kleen which can help with roller marks and bubbles.  If that doesn't work, you might be looking at removing the sealer and starting fresh.  The driveway definitely needs to be clean before applying sealer  

    • After application onto my driveway how long do I need to wait before I can drive on it?

      6 to 10 hours 

    • How many gallons do I need for driveway that is 2 car width and 3 car length long

      Assuming your driveway is approximately 24x56, you would need about 4 gallons at a coverage of 400 sqft per gallon. 

    • Your showing a price o $49.00 on your ad. When I click on the add to order it show s $158. ??

      Starting at $49 for one gallon. 5 gallons is $158. 

    • Can I use this on garage floor

      Yes, but a better solution would be Siloxa-Tek 8510. It is a penetrating sealer that is salt and oil resistant. 

    • Does the finished product become slick with snow or ice? Using product on exposed aggregate.

      It will be a bit slick when wet.  You can add shur grip to the sealer to add traction without affecting appearance shur grip

    • Would this be something you'd recommend using on a basement floor to make it easier to clean and prevent breakdown of the floor?

      We would reccomend a penetrating sealer such as our Ghostshield Siloxa-Tek 8510 (

    • I had a partial one gallon can of diamond clear in my garage. Age unknown. Gave it to my aunt to cover a cement angel she received. She painted the entire angel with the contents (which had become black over time). She called me today asking what to do because her angel is black and looks awful. Thoughts?

      The sealer was black or the angel was black? Either way, i would strip the sealer off using Uni-Stripp and once all of the sealer is removed, wash the angel to remove any other dirt or mildew left behind.  If the black is gone and the angel is clean, i would then re-seal with new sealer.

    • Is it possible to add a color to this sealer for a driveway and sidewalks? If so, what type of color?

      Absolutely! You would want to look at the Universal Color Packs (

    • Hi I am looking foe a siliconate penetrating sealer. I'm not sure if Diamond Clear meetsthatcriteria. Could you please help? Ivepoured a new sidewalk and patio slab (12 yards) in Minnesota and want to use the correct product. Yours was suggested to me.q Thank you.

      For penetrating sealer, I would look at the Ghostshield Siloxa-Tek 8510

      This will do the best job of protecting against salt damage .

      Dry to Touch < 1 hour
      Recoat 2 hours minimum
      Foot Traffic 2 to 4 hours
      Wheel Traffic 6 to 10 hours
