    One more question. Does the heavy duty require one coat or can a second be applied. If a second is applied then what is the recommended time period in between?

    Do you have a product for regular (non-stamped) concrete that has the wet look? My concrete tends to look a bit better wet.

    Also - How long would shipping typically take from your facility to Chattanooga, TN?

      Wet look sealers will not work on plain poured concrete. Dries very blotchy and uneven. 3-5 days to TN.

    How would this product compare to Armor AR350 outside of the wet look? Armor claims their product last 1-3 years on exterior surfaces. How long does your product last? I am looking for something to seal and older concrete driveway (not stamped) to protect and help keep the look after pressure washing.

      The MS Heavy Duty does not have a wet look after applying and will last about 5-6 years.

    Plan to purchase this product to apply to a natural flagstone sidewalk. I thought I read somewhere that it would help stabilize the river sand that is in the joints. Is that correct? Thanks!
    • We will reply to your comment shortly.
      thesealerstore · 05/09/2020
      No. It is not possible for a penetrating sealer like this to harden or stabilize sand.

    I live near Charlotte NC and just installed a new in-ground salt water system swimming pool. The poured concrete deck is coming up on the 28 day cure time. Is this your recommended product for my application?

      You will need to remove the stains first.

        Is there a product we can use to remove the stains? Or do you know of anyway to remove the stains?

          thesealerstore · 09/30/2019
          Try watered down bleach at 1 part to 4 pars water. Apply, let sit for 10 minutes, and then rinse well with water to remove.

    Hello! We have about a month old driveway. We bought this product to seal our new driveway. The leaves from our tree have started to fall every time it rains and have left ALOT of staining on our driveway. (After the rain we try and get them off with a broom) If we apply this sealer will the stains from the leaves fade away still, or will the stains be permanently? I don’t want to look at all of these leave stains long term on my brand new driveway so I am nervous if we should seal right now or wait for them to fade. Any advise is appreciated.

    How do you remove the cap from the 5 gallon? We remove the band around the large cap but could not figure out how to properly remove the cap.

    I applied this to my driveway last summer. Excellent product. Should i power wash my driveway and re-apply the Masonry Saver (Defy) All Purpose Heavy Duty Water Repellent again this summer?

    How long does the protection last?

    Greg · 06/03/2019
    I am contemplating to apply this penetrating sealer to concrete pavers for longer overall protection, and then apply a film forming acrylic or epoxy sealer on top in order to lock the joint sand and possibly enhance the color. Would that combination work with either solvent or water based film forming sealer? Will it stick well to the surface treated with penetrating sealer?
    • We will reply to your comment shortly.
      thesealerstore · 06/04/2019
      No, that will not work nor would it make it last any longer.

        Greg · 06/04/2019
        Thanks a lot for prompt reply! Could you please explain why not? I installed the pavers last year and now I see some mild efflorescence in certain spots. I thought the silicone sealer would address that issue before I put acrylic on top. I was also told someplace else that a solvent based sealer should adhere just fine after silicone has been fully cured. Thanks again!

          thesealerstore · 06/04/2019
          No sealer will stop efflorescence. Putting the first coat os HD on will repel the Paver Sealer. Does not matter the base.

    Not sure if my patio was previously sealed with. Does this stuff work on solvent based ?
    • We will reply to your comment shortly.
      thesealerstore · 03/25/2019
      If the current sealer is still beading water, then no. If it is porous and does not bead water, then yes.

    Using in an indoor space concrete slab with brush finish just need water sealing and ability to mop... is this the stuff? Also does the pump sprayer mater or could it be a hand pump sprayer vs an airless mechanical? Also is this sold in stores?
    • We will reply to your comment shortly.
      thesealerstore · 07/10/2018
      The pump sprayer is the correct way to apply. This product will work for your scenario.

    I have a 4500 sq foot driveway of colored concrete pavers of varying sizes. Pavers have joint lock sand. Is this appropriate for this application? How long will one application last? 7 years? How many gallons will I need? Thanks

    Are you just trying to seal the pavers or seal and enhance the appearance with a wet look and/or shine?

    Hi,
    First I want to thank you for getting my back order to me on time. I was power washing my drive when the FED X truck arrived with my 10 gallon order. The next day when the drive way was good and dry I applied the DEFY as instructed and waited a day for it to completely dry before testing it and boy was I amazed the water just beaded up and ran off and my drive way still looked dry. Thank you for a Great product.

    You show 75-150 per sqft. For concrete But the directions how 150-300. Which is it? I have 1800 sq ft oc Concrete.

    It varies based on the porosity. 150 per gallon is normal.

    I have just about 650 sq ft of brand new pavers I installed in Jacksonville Florida. Do I need to put two coats of Defy Masonry saver? If yes does that mean I need 10 gallons or is the 5 gallon enough

    This product require one coat. About 5-7 gallons for this.

    I've power washed my driveway and walks. I have 2200sq ft to seal. How much of the Heavy Duty Water Repellent do I need, and how do you apply it? Do you spray it with a garden tank sprayer then roll it, or just spray it?

    Also can I use this on my garage floor?

    15-20 gallons for this. Just one coat. Best to apply with a pump sprayer. No need to back roll. See this for additional info:
