    • 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 (

    • Best times to reseal my stamped patio? Spring or Fall? And how often? Thank you

      We recommend once a year.   Spring or fall, doesn't really matter. If you seal it in the spring, it will look the best for the summer.  If you seal it in the fall,  you get the most protection for winter.

    • What’s your best sealer for old concrete driveways I’ve been using diamond clear every year or two

      Depends on what your goals are and what you want to seal against. Generally I would recommend a penetrating sealer such Ghostshield Siloxa-Tek 8510.

    • We used one coat of Super Diamond Clear on our new pavers. It looks great but it still smells awful after 2.5 days. I don’t want to use a second coat unless I know the order will get less and less with each passing day. Help!

      As the sealer cures, it should smell less.

    • I have a 5 gallon can of Euclid Super Diamond Clear Concrete Sealer that was left by the contractor who installed a raised aggregate stoop and walk for me 4 years ago. It seems to be okay. Is it safe to use (after proper cleaning) on my stoop to recoat?

      If it is still liquid,  it should be ok

    • I put Super Diamond Clear 350 on my pavers and they turned white in some areas. Why did this happen and what can I do to get rid of the white areas?

      Most likely effloresence from water coming up through the concrete pavers.  Spray it with xylene, then reseal

    • If I spilled a whole 5 gallon pail of this on my asphalt driveway. And someone threw speedy dry on it and it was allowed to dry, other than cutting out this section of asphalt, is there any other way to remove it?

      Anything that will remove the sealer,  will also likely remove the oil in the asphalt.   Physical removal (scraping) of the sealer is likely the only option

      Yes, please check out the universal color packs.

Every year we have had to pressure wash it an seal it again because it turns dull and has a white haze to it. We were told we have to strip it and reseal it. Can you tell us what we would need to do to get the shine back and not have to seal it every year?

      Sprayer or roller would be your best bet.  We use a 3/8" nap roller.

    • I have a stamped concrete patio that had the Super Diamond Clear applied about three years ago. Is it safe to apply another coat of the same sealer on it now? I know the surface must be clean. Will pressure washing and scrubbing with a brush be good enough? Or do I need to do more prior to reapplying the new sealer?

      Sounds like you have a good plan!  You can soften the existing sealer with xylene as an added step, but as a general rule, solvent based sealer to solvent based sealer is good for re-application.

    • I have an exposed aggregate front porch that was sealed in 2008. When removing a stain this past winter, the cleaner removed the seal from one small area of our porch. If I ensure the porch is free of dust and is dry, can I simply apply another coat of Super Diamond Seal or do I need to strip the old sealant off the porch first? Will the new coat bond to the coat that is already on the porch?

      If your porch was sealed with a solvent based sealer previously, you can usually go back over top with a solvent based sealer provided it is clean and dry.  You can soften the old sealer by spraying with xylene, and then apply your new coat.

      350 to 400 square feet per gallon

    • Can this be used on brick floors?

    • 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.

      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

      6 to 10 hours

    • 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?
