However, for any stone you can check for the need for sealing by doing the “sponge test”… That is, to drop a sopping wet sponge or rag on the stone, and allow it to sit for a couple of minutes. If you seal one that does not absorb the sealer forms a film on the surface of the stone and will quickly look splotchy and uneven as it wears away from normal use and cleaning. I wasn’t able to find out whether or not antique brown should be sealed.

At this point, though, to seal or not to seal, is the least of our problems. It’s been 2 months since installed, and the fabricator said it was sealed prior to installation.
You then remove the sponge and wipe up any water left on the stone. There are also directions on the sealer products that youmight find at any hardware store. Thanks, though, for taking the time and care to respond to my request, this morning.
Why Should I Seal My Granite Counter Tops? by marblelifeproducts.com
They can retain their beauty indefinitely with proper maintenance, including sealing. These substances can make your countertops dull-looking and omit a rancid odor.
It’s recommended to re-seal your granite surfaces at least once a year. It may have been sealed by the installer when your countertops were installed. Unfortunately you don’t know what type of sealer was used, when, or how it was applied. There are several steps involved in properly sealing granite surfaces. Spray enough of the sealer on the countertop to thoroughly wet the surface. After ten minutes use a clean cloth or rag to wipe excess sealer up and buff dry. Do not clean or expose to chemicals, oils, or food prior to then. Using only quality products specifically made for granite, the natural beauty of your stone countertops can shine through.
Granite is a porous rock with small dips and crevices that can trap substances. The denser a piece of granite is, the less likely it is to stain. A lighter colored piece of granite will stain more easily than a darker colored one.

A sealer places a safe, transparent layer into the pores of the granite to block any substances from getting in. If you purchased a pre-owned home, the prior owner may have applied a sealer. After wiping up the second time, lightly spray the surface, then wipe up with a micro-fiber towel.
It’s important the sealer doesn’t dry before the ten minutes are up.
Why Sealing Granite Countertops Is Important by archcitygranite.com
And while you don’t have to seal it when it’s used as a countertop, it’s recommended. At least once every five years, a sealant should be applied to prevent staining from oils, water and other liquids. Grease can stain granite, as can colored liquids such as grape juice and wine. Granite is porous and can harbor bacteria; sealing helps cut down on the cracks and crevices where bacteria can live. Not all pieces of granite have equal porosity, so you may have to seal some pieces more frequently than every five years. If the water beads, it’s fine; if it soaks in, you should seal it.
If you discover any hazy spotting, spray a bit of sealant on the cloth and wipe at the spots.
If your granite countertop is properly sealed, liquids and oils will bead on top of it rather than seep into the stone. Sealing granite can also prevent etching, caused by cleaners or acidic foods such as lemon juice. While we don’t recommend using products with bleach, ammonia or acids to clean granite, you can clean surfaces with mild soap and water and countertop cleaning liquids.
Wearing gloves, spray the sealer uniformly and in a generous layer on the countertop.
Blotches Imperfections In Granite by living.thebump.com
Although some granite may have a naturally blotchy grain pattern, other imperfections you notice on your granite may be man made. First choice is the most expensive granite and contains no visible imperfections. The multitude of natural defects and blotches in second quality granite, on the other hand, often make it a poor choice for counter tops. Dark or solid colored granite shows natural imperfections, dings and spills more easily than lighter granite. This can be remedied by scraping away the crustiness with a plastic scraper, but it takes some elbow grease and patience. Applying a homemade poultice, or cleaning paste mixture, specific to the type of spill can safely pull out the substance that has seeped into the granite.
Professionals who have experience working with granite can remove scratches or other defects without causing further damage.
Sealing your granite every three years protects it and helps maintain its luster. Although granite in any category is equally durable and can be polished to a nice sheen, imperfections and blotchiness are detected more easily in lower quality granite. Additionally, since most granite is a mixture of colors and patterns, any seam in a granite counter top may be clearly evident, sometimes making the overall appearance seem mismatched once the counter is installed. Spills from oils, dark sauces, red wine, and organic material such as acidic fruits can create dark splotches on granite even when wiped away quickly. A professional may repolish the granite to mask the imperfection and apply a granite sealer on the entire surface to protect it from stains, preventing further damage.

Need Advice On The Care Maintenance Of Granite by talk.collegeconfidential.com
The kitchen turned out beautifully and for the most part, the whole project went very smoothly.
My granite countertop had supposedly been treated with some sort of sealant. How is a properly sealed granite countertop supposed to look like? I would call the installer and ask them to come out and take a look. The polished granite never needed anything more than a wet rag to maintain the shine; a polished surface would not ever feel sticky, as there is no finish on it.
If something like softscrub with a sponge doesn’t get rid of it, they may have to buff and repolish those areas. He told me that he had already called the granite installer about this problem so the installer should be coming by in the next day or two to take care of the problem. There is one for granite or the all purpose one (in cucumber or lavender scent), which works fine on granite and marble. Our granite countertop easily shows oily residue from baking and other greasy operations, but you can clean it up with regular non-oily cleaners.
Should the sealant be totally transparent ( invisible) or can you expect to see an opaque, filmy layer? Seems like they may have done a poor job on the sealing if you see a blotchy film. I can imagine if they used some type of sealant on honed granite, it would start to wear away after a while and perhaps develop sticky patches if something acidic (just guessing) was spilled there. The idea of sealing granite and marble is ridiculous–just a way for them to make money. I had ours resealed a couple of months ago and it felt sticky and tacky and looked terrible. Anyone heard about this business of granite emitting radon? It does not work as a sealant, and it will quickly evaporate from stone surfaces.
The radon stories were all over the media a month or so ago. Our counter tops are a multi colored stone and we are so happy with them.
Should I Seal Granite? by mygranitecare.com
While there are stones that absorb liquids like sponges, there are stones that are naturally so dense that no liquid is thin enough to be absorbed by them. Since they won’t absorb any liquid, it is pretty intuitive that they will never get stained. If you polish it, it effectively will not absorb a single drop of anything. Wipe it dry and observe if the areas under which the water has been sitting have become (temporarily) any darker than the rest.
If not, or if the stone is to be installed where the likelihood of spillage is minimal or nil altogether, it would be a totally useless exercise that will only help put the kids of the impregnator’s maker through college.
In fact, nobody ever reported any stain on a polished piece of travertine.

This test is well known in the stone industry and is used to determine if you need to seal your stone, when it needs to be resealed, and if your natural stone is perfectly sealed.

It is a matter of absorbency as some stones are more absorbent than others.
On the upside, film formers may have excellent aesthetics and sometimes make a dull stone look glossy.
Check every hour to determine if the surface is darkening where the water has been applied. That’s because of the different absorbency characteristics of various natural stone surfaces. If the first application barely penetrates the surface, you may not need a second coat. Grout – cement material between the tile joints – will take two coats of sealer, and needs approximately 15 minutes between coats. Is there anything wrong with using general use daily maintenance cleaners such as window cleaners and dishwashing liquids on natural stone? Natural stone, ceramic tile, and grout are special surfaces that have unique characteristics and require specific care. Although window cleaners are streak-free, they are usually alkaline or acidic in nature. In addition, window cleaners and detergents often have mineral deposit removers that can damage your stone because it is made to react with minerals. If they are not completely rinsed away, they can cause stains and attract water-based and oil-based stains, as well. However, you should only do this if the tile is being mechanically installed.
This can occur either in the installation process or after a heavy-duty cleaning and rinsing process. Locked-in moisture will usually wick salts and alkali substances up through the stone’s capillaries to its surface. If you notice a haze or footprints after applying your sealer, apply more of the same sealer to the surface – usually it will dissolve the original sealer residue, which can then be wiped away. The real question is, how long will the sealer last and keep your stone stain-free?
Granite Gold Sealer® | Duration 1 Minutes 26 Seconds
We manufacture the best quality sealers on the market today and recommend re-sealing every one to three years on interior areas, and every three to five years on exterior surfaces. Most general-use cleaners, including window cleaners and dishwashing liquid, can break down the life of a sealer. I want to seal my granite kitchen counter – what are your recommendations? Ensure the counter is clean and free of stains, loose dirt, and debris. Make sure your floor is protected from sealer running off the edge of the counter. Do not spread sealer beyond a reasonable working area – usually a four to six foot area is considered manageable.
Liberally apply the excess sealer runoff from the backsplash to the counter deck top. More absorbent surfaces may require additional sealer applications.
Using a window squeegee on the backsplash and counter deck top, move excess sealer to the next section on the deck. We created our products for specific exterior applications and environments. They are great for harsher exterior applications on stone, brick and concrete walkways, patios, stone walls and for pool aprons. It is always best to test in an inconspicuous area, or do a test piece, before applying enhancer to ensure product performance and satisfaction.
Pour clean water about the diameter of a golf ball in several locations around your surface. If it is, this means the surface is letting water in and you probably need to reseal your surface. Assuming that your surface needs a second application of sealer, the dwell time between your first and second application will vary. The more absorbent the surface, the less time is needed for the first application to penetrate.
Waiting 15 minutes is a good idea, but some stone will require you to wait up to 30 minutes.
Ceramic tile and porcelain are generally non-absorbent and do not need to be sealed. With prolonged use, they can break down the stain defense provided by your stone’s sealer. Dishwashing liquid, although mild, contains surfactants – wetting agents – that do not evaporate. Sealing the back of tiles can minimize dampness in humid exterior environments.
How, When And Why You Should Seal Your Marble Or Stone Tile. | Duration 5 Minutes 13 Seconds
If you are using an adhesion mount, do not seal the back of your tiles as it will likely result in an adhesion failure. Efflorescence is a white powdery substance that is produced when cement or masonry material such as grout, concrete substrates, and/or cement adhesives become wet. Sealing the surface prior to moisture evaporation may cause efflorescence to appear. After the moisture evaporates, the white powdery substance presents itself. In each case, we recommend that you seal the surface again after the removal process is complete and the surface is completely dry. This assumes you are using a maintenance cleaner that is not damaging the sealer.
Mask off or protect all surrounding areas that are not to be treated, including cabinets, painted walls, etc. Allow sealer to dwell on the counter for 15 to 20 minutes to gain maximum absorption into the stone. Our exterior sealers also have excellent salt water resistance. A warranty may give you back some of the purchase price of the sealer, provided you still have your receipts and can decipher the legal fine print.
Sealed Granite Still Absorbs Water [Archive] by johnbridge.com
The sealer helps repel water a bit, just that it still sucks up the water when it is left there for a few minutes vs seconds when not sealed.
Is it normal for the tiles to have a wet look when applying the sealer? Grout sealer may streak the surface of the granite if it is real porous. Some of those guys just might know a little more about that stone than we do.
You cannot do this until the stone and grout have completely dried. May also be used as a pre-grouting sealer over clean stone surfaces a minimum of 1 hour prior to grouting. Is there a diference between solvent based vs water based sealant?
I put some water drops on various areas of the surface and 5 minutes later the drops were still there and weren’t absorbed whatsoever.
Why Should I Seal My Granite Countertop? by rockdoctor.com
America has seen a rising love affair with granite kitchen countertops, and with good reason. Some people are frightened away from granite countertops by the perceived complexities of caring for natural stone, but it really isn’t too difficult, as long as you know what to do. It’s solid stone, of course, which makes it much more dense than many other countertop options. This means that if moisture does work its way into the stone, it can stain it permanently. Basically, anything that can stain your clothes has the potential of staining your granite. So you can see why it’s important to regularly seal your granite, but how often is regularly? That means that different types of granite, mined from different quarries, will have slightly differing amounts of porousness. More porous granites, however, might benefit from slightly more frequent sealing. If the space under the towel is dark when you pick it up, that means that the liquid has seeped into the granite, and it might be time to re-seal.
Granite is resilient and beautiful, an investment that will give you lasting returns year after year, if you treat it properly, and that means keeping it clean and protected with a good granite sealer.
Part of what makes granite so desirable as a material for countertops is that it’s naturally tough. It also has a beautiful texture that’s resistant to chipping and cracking, and is easy to wipe clean.
Though most granite is naturally moisture-resistant, it’s also porous. Colored liquids like grape juice and red wine are a couple of the culprits to watch out for, as well as grease, oils, and fats. Liquid will bead up on a properly sealed granite surface, allowing you to simply wipe it clean. One of the other selling points of granite is that, as a natural stone, each piece is unique. In general, granite countertops only need to be sealed about once a year, or even every 18 months. A good test is to leave a paper towel soaked in water or mineral oil on your countertop for a few minutes.
Before sealing your countertops, it’s important to first make sure that they’re clean and dry.
Granite Has Blotchy Appearance by countertopspecialty.com
We’ve been told from the installers that because there are so many colors in this granite, what we are seeing is the “veins” of different colors at the surface.
Some with tighter patterns or fewer colors won’t appear as blotchy or at least it will seam more uniform. What they can’t seem to get their mind around or accept is that the entire slab including all it’s minerals, performance characteristics (absorbency, acid-sensitivity, maintenance and repair capabilities) is “unique” as well. But even quartz countertops have performance and maintenance differences between different colors, etc. But in general, all granite countertop slabs come from the stone warehouse already polished to it’s full shine. Granite is quarried in big blocks, cut into slabs and then finished at the factory on big machines that use intense friction to smooth the raw granite surface into a mirror-like finish. Granite is very hard, so this finish is difficult (but not impossible) to damage. As noted , some stones do take a polish better than other stones and sometimes you can get a poor grade or “bad” slab. Fabricators should clean the granite counter top prior to sealing, but granite sealers penetrate into the stone and do not form a “film” or “coat” so even if there was debris left on the surface it could be cleaned off after sealing and wouldn’t be the cause of what you are seeing. Sometimes there is good reason to complain about the look or finish on a slab, but it’s pretty rare and usually involves a bad slab. When you look at it from an angle, the finish looks like it has a polished and matte finish, with the matte looking finish looks almost like swirls.
The fabricator said it was the fault of my contractor and said the cabinets were uneven. This worked a little but overall my countertop looks dirty, scratched and stained. If not sealed completely or properly then it’s not surprising you have stains. For most varieties this is not a problem, but for some colors it can pit a lot. Really, without seeing it in person it is hard to make an assessment. The granite in the bathroom and by the two counters next to the stove aren’t pretty but the island is very distracting. There’s no reason you should be dissatisfied with your kitchen granite especially when you have examples of the same granite color in your home and your neighbor’s home that are obviously of better quality. These are not small areas, they are a good size areas (like the size of a fingertip). I understand small spots, but one part looks like a 3 inch long burned spot and the other looks like a 4″ by 4″ rust stain. If the stains are recent and not too deep, then the above product is effective.
I informed the builders to do something about it and they said it’s the naturally occurring color in the granite.
If indeed it is a natural part of the granite itself (which it could be), then no. I cannot believe that the place where we got it didn’t explain that the slab we were looking at is what we are getting. I called the owner and he said they get it polished from manufacturers. This is 100% normal and what any granite or stone with movement in the pattern looks like.
Just as noted in the above article, the minerals are of different color and composition and reflect light differently, which is apparent only at certain angles. If not uniformly smooth, then the blotchiness could be an issue with the surface finish. Showroom samples are “representative” of the particular color or variety of stone, but the color and pattern of most varieties can vary from a little to a lot. If you had picked out the exact slabs you would have noticed any undesireable spots, pattern, color or mismatched slabs. My current granite just has a few larger spots than others and looks pretty uniform.
Has anyone else had the same and how did you deal with this? Certainly you may not like the look of the vein or other aspects, but nothing is wrong with you granite countertop in this regard. I gather that you did not pick out this exact slab or surely you would have objected to the vein at that time. This way you avoid unpleasant surprises and know exactly the color and pattern you’ll be installing. We really wanted to wait until they receive more but were told that it will take months. I have stopped looking at them from an angle and just see the pattern and the shine. I was told it was normal because of the different variations in the stone. Light reflects differently off all these and when looking at certain angles it can appear blotchy. When we awoke this morning, we saw that there were many blotchy, dull spots and pits that you could feel and touch along with what looked like small scratches. They already told us that we picked out the slab but also, in our defense never educated us in any way what to avoid in doing so.
I wish they would have showed it too us and we could have actually chosen a spot to ‘hide’ it. It honestly looks like a spill, the way a liquid might pool and then spread a little. We have the kitchen island, the counters, a half wall, a bar and a slab to go under a wood burning stove. But it could be this was the only way they could cut all the pieces.
There is a large, finger sized/shaped spot, of a different color, in the center kitchen island. We have pictures where they set a roll of tape at that very spot, almost like they tried to hide it. It was covered by dust from the tearing up of the tile floor, and it was very hard to see. The fact is thought that this isn’t abnormal to have an area, spot or line of color that is very different from the overall granite color and/or seen in only this spot. Maybe you can find a creative way to cover the spot if it is truly unsightly, but often after a while you don’t even notice these and it’s just part of the organic look of a natural stone countertop. The installer agreed to replace the most prominent piece (we looked at several slabs before finding one that would work without blotchy places) and also came in and applied another finish, sanded and polished and re-applied sealant.
I have a photo before the granite was dropped in place, a photo immediately after, and now the photo with the darker splotched areas showing. If not, then nothing else you can do except have the slabs replaced. The plan is to completely replace one piece and repolish/seal or something on the others. First , as noted originally it can simply be when looking at a low angle you notice a difference in color and pattern reflection that can seem like something “blotchy” is on the surface. A second problem is regarding improperly applied sealer, which leaves a dull, streaky or blotchy haze on the surface that can be seen at all angles, but is most pronounce when viewing countertops at low angles. Doctoring is almost exclusively a problem with black granites though. and yet another blotchy problem that can produce weird spots on new granite is related to the adhesive absorbing and bleeding through to the surface of the granite countertop. Some varieties (colors) are more prone to bad slabs than others, but this can happen with almost any granite color.
We are always glad to provide answers and help regarding such matters, but it is also always a good idea to have a stone fabricator (your installer and another fabricator) come take a look. Don’t know the outcome, but veins and the various different minerals and pattern variations will be seen when looking at a low angle.
The surface will all be smooth/shiny and should not look add when looking down. I have gotten down eye level with the reflection of the light and it does seem to be the veins. Granite is very hard and difficult to scratch beyond faint surface scratches, but even these are not common or usual really. Also, the most common cause of a “blotchy” appearance is improperly applied sealer. A sealer should not be left to dry, but it is too common that the installer will apply the sealer and then just leave, telling the homeowner to let it soak in for a day or two. Often letting the sealer dry is not a problem on lighter granites since they have higher rates of absorption and will drink up all the sealer even when left to dry. If this has occurred then the sealer will need to be stripped off using methylene chloride and then re-applied properly.
However, the surface is blotchy and looks dirty, scratched, and old.
It’s hard to explain, you can see what look like “etchings” all over the counter, especially when the sun is shining, and from many different angles. You just aren’t used to looking at granite and your guests will not think they are dirty or notice a thing unless they decide to inspect the granite countertop at all angles. No two stones have the same composition nor will they look the same.
Quartz countertop manufacturers of course have tried to eliminate these differences by making a stone-like product with uniform composition, only with different colors. Also , granite countertops can have a number of different “finishes”. It’s true that fabricators typically just cut and polish edges, but do not do anything to the top finished surface except clean it and seal it if necessary and requested. Unfortunately, if you have such a dog stone, there isn’t much you can do about it especially if you picked it out. Mine seems to get worse and spots and rings if you don’t catch a liquid spot immediately. They tell me the granite is “soft” and they are no longer installing in kitchens but there are many beautiful pictures on the internet with this granite. Typically, in such cases this is due to a film (like soap scum) is on the surface. I feel it is artifacts unique to the piece as they look like scratches or water marks but they cannot be felt. The master bath has the same granite, it is gorgeous and shiny and not rough. We didn’t have the option of choosing our own granite slabs.
They should be evenly smooth and shiny without excessive pitting (all granite can pit so, but typically new tops don’t have many yet. Natural stone can have all kinds of pattern and color variations including unusual inclusions or spots of a different color that is not repeated in the pattern. However, if the stains are deep or old, then they may be permanent. Granite colors and patterns can vary a lot and sometimes even contain a stray spot or color. If your countertop surface is completely smooth to the touch, but only looks weird and blotchy at a low angle, then it is normal. You were ready to love it and trusted the contractor to do the best possible. Choosing the exact slabs allows you to choose those most pleasing to you and that will match up at any seams. And really for relatively short jobs like a countertop installation, it is best to be present when the work is done. I almost want to get the whole thing replaced but that would be costly. The lesson here is that you should always choose the exact marble or granite slab that you wish to make a countertop out of.
Another tip is to discus with your fabricator how a particular slab will be cut and map it out to avoid including any unwanted features of the slab.
These two pieces are very large and they were stocked in a way that you were unable to have a good look of it. It is a normal aspect of granite when viewed from certain angles, but just due to mineral pattern variation. Granite is made of many different minerals and crystals that form patterns. They were patterned, cut, polished, sealed and installed yesterday. The counter just looks dirty and old beside the fact it was very costly. The very reason they need to be there is to evaluate the granite slab integrity and quality. We didn’t notice it till last night when everyone was gone and all the work had stopped for the day/weekend. Wouldn’t be too surprised if they did purposely try to hide it and if so, then they likely will make every excuse possible to keep from replacing it. Tonight, 7 hours later, there appears darker round ~5-inch areas above where the adhesive to the particle board had been applied applied.
Is this normal because solvent is coming up through the granite? However, it is usually due to using accelerants with the adhesive and can often be permanent. If not the e-book methods may help some, but you may have to continually repeat the steps over a long time to completely remove. After repeated calls and visits, we have finally had someone (we think) that can remedy our blotchy granite countertops. But when you look straight down the surface simply looks smooth and evenly reflective. Third , it could be a problem with resins (not common) or “doctoring”. A bad slab will not polish well, make look spotty or blotchy or dull, may have a gritty feel to it, etc. You also don’t have to look hard to see them – as someone else also posted. He said it was the water-based adhesive coming up through the granite and it just needed to bleed out. I have gotten down eye level with the reflection of the light and it does seem to be the veins.
If you have a lot then it could indicate neglectful handling of the stone on transport, storage or install. If a sealer was applied and any excess sealer was left to dry on the surface it will create a dull hazy and/or blotchy appearance. No, it should be applied to saturation and the excess wiped completely off the surface until dry not more than 10 minutes (for most stones) after it was first applied.
But it is not the correct way to do it, can and often does lead to a poor appearance.
