HELP!! Mystery stains on new marble pool deck

last modified: 2 years ago

We are building a new home in Florida and we just got our Marble pool deck installed. It looked beautiful for about two weeks and then this started happening. Can anyone tell us what this is?? We have a solid concrete poured pool deck and the marble pavers were laid over the concrete. We wanted the pavers to lay on concrete instead of dirt. We thought it might be the rebar that is under the concrete, but we have a good friend who owns his own concrete company and he is telling us there is no way it's from the rebar. We noticed the stains a couple days after a good rain. We know it's not from a well either as we have no irrigation installed yet. I should also mention that it starts to fade and almost disappear and then it comes back again. Asking for help from the experts. Thank you!

    How is everyone doing with their patio / stone issue? Is everyone still having issues? Anyone have any luck with any specific product or technique?

    Would love to hear updates. @reedrxrep @Teresa Chaplin @Jana Snyder @kberry4b @Diana Flottmann @lisaslzy @A W

    I have had my contractor pull up our stained stone. Replace the sand from a Masonry supplier and not a landscape supplier and mortar down the moat outer coarse of the stone where the largest gaps in the pattern were. B/w the foundation and the decking.


    we also had the stone sealed with a penetrating sealer within 24-48 hours


    It has been 6 weeks and no signs of reoccurrence.


    🤞

    Here they are pulling up some of the pavers and you can see the staining of the sand.





    Here you can see the staining of foundation or concrete base.


    I certainly feel that it was combination of factors That lead to this but I certainly believe the mineral content of the sand was the greatest contributing factor.


    Also, removing the greatest way that moisture was getting under the pavers by wet setting the outer coarse And sealing the pavers has made a difference.


    we still have not settled with the contractor as it took about 2-3 months to show up and get addressed so we will see how the next 1-2 months go.

    Readyami, thank you! We have some "mixed metaphors" going on with the Texas star decorations and the un-tiki gazebo, but I've always been kind of eclectic anyway, LOL! :-) Tim, thanks! When I was putting the skull up I was thinking "This belongs on Tim's pirate ship", haha! The ball is a Japanese glass fishing float (this one is actually a modern replica), a long time favorite decoration in tiki bars and restaurants the world round. It's as required a staple as the traditional hanging puffer fish lamp (I have one of those too) :-) Mostly they were hung indoors in arrangements of different colors and different heights and sometimes were lighted from within. I can't direct-link the photos, but if you look at the thread linked below (photos of vintage tiki bars) you'll see what I mean. They were also popular as A-frame decorations. My A-frame is actually a little teeny version of the real thing, the traditional A-frames built on restaurants and bars were enormous and had gigantic glass fishing float replicas, period light fixtures or even outrigger canoes hanging under them.

    So from your screen name, I'm going to guess you live here in humidity central. I'm sure others will have some better ideas, but here are a few thoughts. First, if your gutters are overflowing and they aren't filled w/leaves, I would suggest having a deeper/wider more appropriate gutter put in to eliminate part of the problem, not just treat the symptom. Next, Kooldeck here in Fl will always build up mildew and algae. I have always had to powerwash my deck 1-2 times per year to keep it looking relatively clean. We recently refinished the pool and deck and had a new acrylic concrete surface put it which the GC said would be easier to clean than the kooldeck, and it looks good, but it has only been in through the summer. Pavers would be another, though more expensive choice. Lastly, I dont know what PSI your pressure washer is but the 0 nozzle seems excessive. Using some bleach from the pool store and diluting it and brushing it down or using w/the pressure washer should make it easier to clean. If your interested in talking to my contracter, let me know.

    The flood test was done after the tile install. I'm sorry that I don't have any pictures of the installation but I will see if the contractor has any. There is no question that work needs to be done on the door/ledge pitch and sweep but I have NEVER seen the area in question outside the shower wet. I have studied that endlessly, but water doesn't settle in the spots with the stains. I wish it were otherwise, because at least then we would know what corrections might work.

    They did replace all of the overtly stained and or discolored pavers and the. Mixed them into the pattern with the remaining pavers from the original lot.

    I made sure that my contractor used WHITE sand underneath, but still having issues. What kind of white sand is typically used from contractors? Is there a landscape WHITE sand....that is different from a WHITE mason sand?

    Message to BF -

    That's great that this seemed to resolve the problem. So, the pulled up the pavers and what exactly did they do? I read your initial post and it sounds like they used a Mason sand, so what kind of sand did they use now when they reset your pavers? Or was it the color of the sand that was maybe causing the staining? And they mortared all of the edges, correct?

    This is so frustrating!!!

    This is what you want to see under your stone pavers, no staining and just replacing an ugly

    Response to jhcbflorida


    We are still struggling with the staining. Cleaning with bleach or peroxide only helps short term. I think we need to remove the sand and replace it with mortar. Has anyone heard of using Dribond for installation? One of the paver installers we originally were considering used this product. They were more expensive so we didn't go with them. Lesson learned the hard way.

    So we just had our home built in Marco Island and after 3 months of moving in our deck is showing signs of what looks like rust coming thru. Ours was set in sand set on top of concrete so now we are being told it should have been a mud set does anyone know what is the right way to install this

    @lisaslzy we had our lanai under roof taken up, old sand removed and replaced w white sand, crushed limestone, and it’s still happening:(
    Has anyone tried CLR?? We’re at our wits end, builder says they’ve discontinued our shellstone (I can’t imagine why!) so we’re trying to think outside of the box to fix this issue bc we really want our grill put in finally. My husband loves power washing and our lanai stone not under roof looks beautiful, everywhere else, not so much.

  • lisaslzy
    8 months ago

    @Kim G Sorry to hear this. We haven't done anything yet and its a mess right now. I have tried CLR and it doesn't seem to do much. The best thing that works for me is 12% food grade hydrogen peroxide mixed with a little ammonia, sprayed on, scrub after 20 minutes, then mop off. I don't know if its the best solution, but it seems to help ours. Be sure to wear a mask and wear gloves when spraying anything strong. I'm still considering removing stone and having it reinstalled with mortar.

  • Kim G
    8 months ago

    @lisaslzy thank you! My husband sprays chlorine on all the stone, let’s it sit then Powerwashes it off. Of course the stones exposed to sunlight look great, the others like a posted have no change. He was asking about the CLR, he did say the builders had some guys come out and used the solution you mentioned to no avail. Our home is pure white and it just looks even worse up against. Tempted to glaze the stone in that area a different color (if this can even be done or look right), or change the type of stone, just trying to think of something else since nothing else we’ve tried is working.

  • B F
    8 months ago

    So my understanding is that CLR is way to strong to use and will etch the stone badly.


    That being said, ours has returned as well but not nearly to the extent the it was previosuly.


    "Kim G", can you tell me where you got your stone from?


    We also have "Shell Beige" from the "shell stone" collection and this was through Stone Line Group.


    https://www.stonelinegroup.com/portfolio/shell-beige-paver/


    We have received such a run around b/w the pool contractor and the stone contractor/installer as well as the "Stoneline Group" representatives. This includes proposterous statements from the Stoneline Group saying this is a terrible product and they don't recommend it all the way to the other end being their most popular product and my pool contractor installing enough to line up end to end coast to coast with no issues!


    We are the excpetion to the rule! Of course they have never seen anything like this before.


    I could go on but I digress.


    Please let me know where your contractor sourced the stone and who told you it was discontinued etc. I would appreciate the details.


    We are about 5 months now since they replaced some of our sand and some pavers as well as sealing.


    TY

    @B F of course I’ll let you know. I came back to add that our stones were laid down like this and they told us to give it a year and we would assess at our one year, tired of the run around and trying to cover all our bases, we’re super easy to work with but are over it.

    Hi everyone!
    We have Talya Gray marble and after a few weeks after installation, the rust stains were horrible. We used the 50/50 water and bleach mix that was recommended by Wayne and that would temporarily remove the stains.
    Just wanted to let everyone know that I think the staining / discoloration ran its course as here we are 6 months later and we don’t have to use the bleach mixture any longer. We still have some very minor discoloration that occurs but nothing like we did initially.
    Just wanted to let everyone know that it does seem to work it’s way out as others have mentioned.

  • Evan Bollier

    Hello! I just got the french pattern Talya Gray marble travertine (from Stone Mart) installed last week and it looks beautiful- and I want to keep it that way. What kind of sealer should I put on it for best results? Any recommendations? Also- what kind of routine maintenance should I be doing for it? I'm one week in, and no staining yet.




  • Teresa Chaplin
    6 months ago

    Evan - unfortunately it doesn't matter what type of sealer you use or how you maintain it, its a natural process that happens from inside the stone. We had our installed in February 2020 and it was also purchased from Stone Mart and it still looks awful in all the covered areas. We were told not to use bleach on it so we haven't tried what some of the others have but are waiting it out. We were told it would work its way out within a year but its still going strong. I absolutely loved the Talya Gray when we saw it and when it was first installed and now I hate it. Our entire outdoor kitchen area looks dirty and the portion under our lanai is the same. Maybe you will get lucky and yours will not have this issue! Best wishes!

  • jhcb

    Hi Evan! It’s such a beautiful stone isn’t it. I did a ton of research and spoke to a lot of different people in the stone industry. We decided to NOT seal our marble as the more I learned and researched, this was the advice.

  • Teresa Chaplin

    jhcb, would you mind sharing what you found out about not sealing? We had ours sealed with an impregnating sealer, as thats what everyone told us that we spoke to. We will need to have it resealed in 2022 if we decide to continue so I would love to hear what you found out about that! Thanks!

    Best source to decide on Seal or Not to Seal

    Search Keyword "Seal" or "Maintenance"

    I always recommend Sealing as the pros outweigh the cons as long as the correct sealer is applied. Coating type Sealers create the largest issues with natural stone

    Hi Teresa...I'm sorry, I didn't see your question. I received varied opinions about sealing or not sealing our marble. Someone suggested I reach out to a man named Fred Hueston who is a stone expert in Central Florida. When I asked him about sealing our marble...he very clearly stated "No, PLEASE do NOT seal it!"

    Amy, a friend, actually neighbor across the street w the same lanai tiles as yours, and mine (hers has more of the black and doesn’t get as much sun as we do), sent me this text just the other day…
    “In the continuing saga of
    Orange shell stone pavers on our lanai, our friend said that when they make the pavers they put the shells thru a metal sieve and some
    Of the metal flakes off into the stones. It then rusts when wet longer under cover of lanai. Hence why ones in sun don’t go orange because they dry faster when it rains. Have you heard that before?”

    Idk but I bought some Whink and am going to try it in a small area on one of the stones. I’m desperate at this point, I know it’ll break down the stone, but I’m curious to see if it gets rid of it!! I’m so sorry you’re dealing w this too:( how long have yours been down?

    We have Talya Grey marble pavers in a french pattern and when it rained the brown stains appeared. i read through all the comments, solutions and remedies on this thread. Our installer has been using chlorine in a sprayer to remove/kill the staining. its working. Some have used bleach and found that works too. As far as sealing, we havent yet until the rusting stains are eliminated but we will be sealing. We will also be sure to avoid the sealers that only coat the pavers.

    I notified Baystone, the distributor of our marble and they have been working with Magic Marcite our installer to make sure the pavers are rid of the rusting. According to our installer, we are not the only clients he is assisting with this problem. I am grateful that Magic Marcite is an honest company. My advise to anyone with marble pavers is to not give up on treating the pavers to elimate the rust. There is chlorine in the pool water so it seems logical to use chlorine to elimate the problem as chlorine has mot harmed our tiles but kills whatever organic material is causing the staining. Good luck everyone!

    Hello everone. Reedrxrep here. Soooooo sorry I have not responded in quite some time. I have not been on the site for awhile. As you know, I am the one who started this conversation and I am happy to say that after 2 years, it appears we no longer have the staining issue. As you can see in the photos I originally posted, our marble looked awful and I was freaking out. Many experts had said it just needed to run it's course as it was a natural product and it appears that was definitely the case. In the beginning, we used everything from bleach, to rust remover, etc. You name it, we tried it. Anyhow.......I can honestly say we have not had any more staining for close to a year. My husband does pressure clean it about twice a year with a small amount of bleach and water just to brighten it up from all the dirt and pollen that has accumulated over the year. One thing to note.......after checking with numerous vendors, we decided NOT to seal them. Everyone told us with such light colored marble, we run the risk of the sealer turning yellow and lord knows, we don't need anymore issues. We love how beautiful it is and we get tons of compliments. Here are a few photos of how it looks now. Sorry for all the family in the photos but you get the idea. Hang tight my friends, it will get better and we have no regrets.

    Hi! Curious ReedrxRep, What color marble did you go with and who did you purchase from?

    I was told that that the rust happens from when the sandblasting process is done to the marble. Small metal flakes get thrown on the surface of the marble during the sand blasting and that is what ends up resting… Makes sense to me.

    I love to hear that it ran it’s course and Eunice have got a beautiful home! We are also looking at White and just curious as to which why you chose?

  • Kim G
    2 months ago

    ReedrxRep your marble (home too) look gorgeous, you’ve given me hope! Our under lanai still looks dingy compared to the stones exposed to sunlight.
    Kori, exactly what you said. There are tiny metal pieces that flake off and cause the rust, we lifted up a few stone tiles a couple months back, and sure enough, tiny rust spots, craziest looking thing, but that’s the reason!!

    Hi there. For those of you that asked what type of stone I used......it was Aqua Gray 12x24 tumbled marble that we purchased from Baystone Tile.

  • maitte

    So the consensus is not to seal? We have sandblasted marble that was sealed and started yellowing. We’ve asked the installed to pressure clean to remove sealer and reseal. But if resealing is not the way to go then we’d rather not do it. Any advice would be greatly appreciated as this is driving us nuts

    So much misinformation, sealing helps but doesn't stop it. It's basically Tannen stains from dirty water and organics from setting materials. Since you sealed it it cleans up with 12% peroxide. In time after the stone acclimates and the setting materials cure it will go away.

    Thanks Wayne but the stains came up under the sealer and i cannot clean it it seems. the company that sealed it (oil based solvent) stated chlorine could damage the sealer but ill try peroxide like you suggested.
