I know it’s been a while since you posted. Could you share what product you used fir sealing. Thank you!

Your stone is acid resistant to acid except something like hydroflouric acid which should never be in your home anyway. Any well known name sealer manufacturers top of the line sealer will help if applied properly. Our MB-4 sealer is water based has no odor and is easy to work with. 511 has two sealers-the porous plus which is very good but harder to work with. They also have their "sealer" which is cheaper than porous but easier to work with and will require more applications. Which ever one you choose the real key is the application. With your type of stone you will need to apply a heavy first application. It is important that you do your top in sections so you can control the product(ex:centerisland do in 2 parts). You will need to let it sit on the top for maybe 20 minutes or so keeping it wet with more product. This way you are loading the sealer into the stone. You will see the top get very dark-this is the absorbtion of the sealer. Once you get this darkening and it becomes uniform in the section you are working on then remove every trace of sealer from the surface after the alloted time. You must not leave any sealer residue on the surface at all. Thats why you have to do this in manageable sections. Then move to the next section and repeat process overlapping the first section. Another big key to good sealing is to do the entire top with first application and then apply second application 24 hours after the first. This gives the sealer the required time for the resins to cure making the second application much more effective. In the case of kashmir white you will need to do as many as three or four applications. Then if you test the porosity after each application you will find it should be much less.If you use the right cleaning products the sealer will stay maintained for quite sometime.With kashmir sealing can be almost impossible but this method will work much better if you have the time and patience to deal with it.

Ugh! I typed a whole story and just lost it! I will try again... I love marble too and the light quartize but opted for LG Minuet Quartz because of its ease of maintenance. I have 2 kids and a messy DH. We push and pull and drag stuff all over the counters. We don't clean up spills in a timely fashion. I tried but couldn't find a real quartize and now after a few weeks in my new kitchen I am glad I have a low maintenance counter. I can even understand why people use laminate. It's durable and you don't have to think about it. i have to use hot plates but I have always had too so that's no big deal to me. I haven't had my Quartz long but so far it hasn't stained.

Well first I'd like to say, sorry this has happened to you and that I have seen sealers change the appearance of stones, so I can empathize. Usually it's subtle or very little (depending on the type and brand) but It is more obvious with honed or leathered ones and less for polished. And yes sometimes just a casual glance it would not be obvious to some, unless you had an original unsealed (or just one coat) sample side by side with your 3x sealed countertop for comparison. But any person like you making all the detailed color coordination decisions day in and day out, would sure notice right away! I sure would! Oh and I also have to add here that some men are color blind or what I call 'tint blind' so don't let anyone tell you that you are crazy!! As ravencajun stated, maybe it does just need to dry a bit more? And I would contact your fabricator and let them know about your experience. I'd also ask them if they are familiar with that sealer and have been using it for long or is it a newer one for them? They might be experienced with it and can reassure you that yes indeed it will go back to normal. Or something else helpful about it. Typically you test a sealer's effectiveness (fully cured by the way and not before) by putting a single drop of water on the surface. Properly sealed, it should bead up like it would on a freshly waxed car with firm edges and quite a good high and round bubble. Even on a honed or leatherd surface (or grout if it were tile). Needing more sealer would react with loose wavy edges and a flatter bubble. Little to no sealer would react by soaking in entirely (immediately or soon after) or water sitting very flat on the surface. And usually anything but the first high bubble will result in some varying darkening to the stone from the water absorption. In fact, the test to see if you need additional sealer or not, IS this bubble test. Whether initially or several years later. Some stones need no sealing at all and so if they are unnecessarily sealed, will have the sealer sit on top and create this funny sheen, wet look or haze because it's not being absorbed. This type of stone should have a firm bubble, unsealed. Did you happen to do any testing of your stones before hand? So if you do this bubble test now, after your three coats, is there a good bubble or is it less? Actually, check the cure rate for the sealer. It may just be too soon now or was possibly too soon for your 2nd or 3rd coat. So then this water bubble test would be premature. Might need more time to cure. Check the label for instructions. If it's ok and cured, any water still soaking in? Is water soaking in AND it still looks "wet", both? Sounds like a sheen issue of that sealer. Or possibly just be a curing issue. A properly sealed stone should repel water and not be absorbing it and so won't need "drying out". An already sealed stone only accepts more sealer if it needs it and keeps absorbing it. Oh and wiping down the surrounding sink area from splashed water is a separate issue. Those thin microfiber cloth or thin sponges are great for that by the way. A few quick swipes and you're done! The yellow tint issue might be from their particular formula. This is immediate and not an issue of "yellowing" over time and UV exposure like typical white oil based paint yellowing. This is something different. Maybe this is a new formula for them? I'd have to research on that. I'm sure you followed manufacturer directions and timing of the additional coats. But I also know from my own experience, that honed and leathered surfaces take the sealer differently than polished. I had seen problems before so I did testing on my own surfaces (before installation) before choosing which one to use. Had several unexpected results. I'm familiar with Dupont StoneTech but not Latictete's. In a standard regular penetrating sealer, in my experience, no it is not normal for it to look "wet" after 48 hours. You said specifically that this was NOT the enhancing sealer. That usually darkens it dramatically. (Like wetting a dry stone and it darkening a lot, but then after drying again, lightens. If you want that darker look, the enhancing sealer will do it). But a wet look is a different issue. Enhancers sometimes include a "wet look" formula. And they typically label it right up front as such. It is unusual for a standard penetrating sealer to include this "wet look" but I've seen it once before. I forget the brand but remember the labeling was not up front about it. This was a few years ago so this may not be a current issue. In my tests of my own sealers with my honed and leathered stones, the most unexpected result from several of them was the sheen increase. I think I tested four or five and a few were especially bad. They all did darken to varying degrees too. I was surprised at the varying results from the different brands of standard "penetrating sealer". I did each test tile in overlapping strips so I could compare each section later after fully curing of non sealed with one coat, then two then three. The 3x sealer (or even 2x) on several were unacceptable for what I wanted to be a matte surface. I ultimately chose the one that had the least added sheen. (I also tested for water repellency, stains, etching, etc) I didn't notice a big color difference although they did all get varying shades darker, but with my buttercream honed and then leathered limestone tiles, I would not have noticed a yellow cast if there had been one. So maybe this added sheen is what you are seeing? Or if really extreme, maybe you could either have a sealer that has added a "wet look" to their formula (check the fine print) or possibly your stone has absorbed all it needs and extra sealer is sitting on top as mentioned before? Do you have any original samples of your stone before sealing? Do you have the sink and/or cooktop cutout from fabrication? If so, I'd use those to test any removal product or procedure on that instead. Or an inconspicuous area of your actual countertop. You might search out GW's resident Stone guru 'karin_mt' (for her famous Countertop Geology / Rocks 101 posts and more) for her knowledge on your actual stone and it's porosity. Some stones don't need a sealer or may react an odd way with sealers. I'm trying to remember if your stone has some unusual properties that would be an issue. Maybe someone else can add to this point. I have seen sealers be removed by either acetone or other cleaners, and sometimes the best removal product is from the same sealer company. If that's the route you need to go but I'd check on all these others first. And with all of this information, if anything like stripping does need to be done, I'm not recommending any DIY sealer removal or experimenting on your own countertop (except for samples), till it is determined by the mfg and your fabricator their liabity and responsibility for this. I'm just trying to inform you of these things to assist in finding out what might have gone wrong. Ideally, fabricators specifically and contractors in general are fantastic and stand behind you 100% till everything is to your complete satisfaction. Unfortunately the reality can be and usually is a lot less than that, with varying degrees of success, as this forum and others can attest to. And you have probably already paid everything in full, but if you haven't yet, I'd wait and withhold final payment till this job is completed to your satisfaction. Sealer and all. And with your fabricator knowing which sealer that was used, I'd put them in a higher category than typical so I have high hopes for you and fingers crossed! I didn't mean for this to be so long but I'm trying to be thorough. Sealers are frequently a total afterthought and I've experienced problems myself and had to experiment and research for my successes so wanted to pass that along. So seems like you might have multiple issues that need sorting out to know which will the correct problem to address. After contacting your fabricator, I'd also contact Latictete's technical support to ask about their sealer, multiple coats for drying time, a yellow tint issue, and what they would suggest for a solution or removal if needed, etc. Maybe you need one of their Reps to come out to look at your situation. I'd still work WITH your fabricator. Unless Laticrete takes over and determines something else is going on. They could suggest using your fabricator for labor to solve the problem. Whatever you do, I'd personally want to know all about things because that's just me. You may be totally different. I've been burned a lot and I get comfort in knowing that what I've researched from the manufacturing company of the product, will be the same recommended methodology used by the person doing the repair or the original work by the contractor. I'd feel most comfortable doing what the manufacturer suggests works with their product in case your fabricator has not been using this sealer very long. Some fabricators change sealers all the time and could not even tell you the name (much less any directions or specs) and even keep it in an unlabeled jar or a different sealer in another sealer's container with a convenient handle they like to reuse. (Ask me how I know). But yours did know so that's great! In any case, I know it's frustrating to have problems at a time when you hoped to celebrate a milestone such as countertops installed and to move forward. So hope you can figure out everything and get a good resolution to your problem! (edited for clarification)
