My fabricator came by yesterday and he says he’s never seen this before. The interesting thing is that it’s only in areas of high use nd the quartzite underneath our dish drying rack is still pristine – there is literally a rectangular area of unstained quartzite underneath the rack (as seen in photo). I find it interesting you also use method cleaner – maybe a coincidence but maybe not. If you cant find this particular product and opt for something else its the microparticles and bleach are important.

I have seen a counter top in ceaserstone blizzard that was similar to this it was just a grime that built up which method daily cleaner wasn’t getting. In the factory the slabs are polished and sealed before this could happen but your fabricator probably didn’t apply sealer until after installation. Slabs that react to oxidization will form rust spots (not green) and even streak down the polish of the slab sealed or not sealed. If natural iron can cause granite to rust orange, why wouldn’t natural copper cause green oxidation? If it’s just green bloom, why are you still talking about it? On these types of stone you almost always have to touch up the edges.

That being said here is the photo in question again with obvious repairs. On the other hand, if these are in fact repairs, the accelerator bloom makes sense, especially considering it isn’t apparently happening anywhere else on the edges. That’s way easier to fix than copper oxidation, the piece doesn’t have to be re-edged. I noticed it started to turn a little green (see pic) where it was repaired. When the granite folks came, they mentioned that they have seen it in the past (if an accelerant was used during installation, as mentioned by granite guru) and they came prepared with a blow torch, and some acetone. The granite company has sent a guy out 3 times already to try different things to lift it, none of which has worked. Most granites are gangsaw and the metal particles come from to the surface in the form of rust after awhile, if you have been cleaning them with soap and water for an example. Just clean it with acetone first and see if that lifts off the white areas in the quartz of the granite. With all do respect, this thread is about green bloom and possible chemical reactions with an accelerant spray, not rust. If you’re going to see mineral deposits, it usually happens after the stone has been installed.

Micro fisures is what i would say was probably stablized to process the stone.

Our installer is at a loss – any updates on your end? Try it first on the back corner just squeeze some on and wipe it with a rag using a circular motion dont push down to hard as this might dull the polish. However, what the op seems to be talking about, green on the edge, is from copper in the stone oxidizing.

That’s normal but in this case it allowed the stone to oxidize everywhere they made cuts. Granite will absorb humidity not just from its polished surface but from the humidity in the air like a sponge, it will rust from the inside out. Most of the big suppliers are now keeping their stock indoors to help prevent oxidization its really not that big of a problem any more. What reason would anyone have for applying accelerant to the edge of a countertop? Granite slabs aren’t sealed by the factory, there are a few quartz products (man made, not granite) that are sealed, the one you mention being the foremost. Guru (if that’s even your real name), the only person that could be “100% hands down” certain it is green bloom caused by accelerator is the dolt that soaked it in accelerator in the first place. The mica, micro cracks and pits in this stone is sealed up on the top with resin from the slab supplier but resin dosent penetrate deep enough into the stone so the edges remain porous and brittle.

I pointed out the mica cause usually that needs a little shot of glue also because its like paper that flakes right out. If stone has iron for rust, it could certainly have copper for green. We can determine if it’s marble like crema marfil, sandstone or a limestone.

Considering the look of mold on the back wall, is there a water source near by that could be leaking? Visit a local monument dealer and see if they can hook you up with some thing similar to this (see photo). We had a granite countertop installed as part of a dry bar when we finished our basement about six months ago. I installed my kitchen about 4 months ago and i can see some small areas of my granite is green. The builder also noticed the greening so he called the granite installer and told them it was turning green. In about 30-40 seconds, the heat from the blow torch pretty much removed the green spot or at least made it very unnoticeable. Put a few drops on the surface around where you have the stain and leave it for an hour or so.

I would suggest you grab some rust converter that is phosphoric acid base, that would be your safest option. Having the slabs on end allows both the top and bottom to breathe properly and 99% of the time does not affect any mineral deposits. There are definitely flaws in the newly exposed cut edges of stone or router shaped edges.

New Polished Granite Tile Floor by

Polished travertine will particularly basically teach airborne dirt and mud and airborne dirt and mud, smears, scuffs, etc. Travertine and marble are particularly exceptionally dense and don’t stain straight forward. Etching is amazingly considerable on a elegant travertine because of the fact it reasons uninteresting and gentle-weight-colored spots. Is marble, granite, or vitrified tiles good for a brand new house?

Polished travertine (marble, limestone) will teach foot site visitors positioned on in time and would require lots greater upkeep (think of high priced expert repolishing) than a honed floor.

So, even if this is puzzling to sidestep acids in the kitchen, oftentimes a kitchen floor isn’t uncovered as much as a kitchen countertop. A travertine floor not almost as lots (until eventually you have it polished).

How To Clean Seal Granite Countertop by

Frequently sealing your granite countertops and natural stone surfaces maintains maximum surface protection and provides long-lasting resistance to staining, etching and soil build-up. Simply spray on to stone surface in three foot sections, wipe with a lint free cloth and buff dry. Polishing your stone regularly brings out the stone’s natural beauty and reinforces the protective seal to provide ongoing protection against water spots and fingerprints. But, don’t polish stone floors unless you want to go skating in your socks! If you ever notice water marks or rings on your granite countertops, your granite needs to be resealed. Most of the time, just cleaned it with a home made cleaner consisting alcohol and dishsoap.

But it is crucial to avoid common cleaners and abrasives that can break down the protective seal and damage your stone. Polishing shower walls and tub surrounds will also help prevent soap scum build-up. You can regularly check if your granite is sealed by simply pouring water (about 3 inches in diameter) on the surface in several locations and letting it sit for 30 minutes.

If a dark mark or ring appears, the water is penetrating the stone and it’s time to reseal. I hated them because they’re always sticky and get dark marks from water or wet dishes left on them. They were originally protected at the time of the install but nothing since. I have been looking into granite cleaners and these sound great!

Should I Seal My Granite Countertops? by

This is usually determined after something has already stained the surface or grout. A very simple test can be done on any surface to find out its porosity.

Some granite (most of the time darker) may not darken at all or very little as opposed to lighter colored granite.

Oils are more common in those areas and can stain or darken the granite. The granite that does not darken with water may already be sealed properly or is a higher quality denser granite and may not need to be sealed.

If it does, you can either be very careful cooking or have it sealed with a sealer that will protect against those oils.

Properly (key word here) sealing any surface will help protect it from staining. Sealers will only last as long as you take care of them and the surface they are protecting. We then apply the sealer, allow it to penetrate, take off excess, then repeat. We also use sealers that continue to migrate through the stone and not just stay on the surface of the stone. Your granite countertops are very expensive to replace if they become stained. Contact us with any specific questions regarding your stone surfaces.

Often a new home will have granite, travertine, or marble surfaces installed without ever being sealed. You may also purchase a previously owned home and have no idea what was already done to these surfaces. You can take a tablespoon of water and pour it on the area in question. If water penetrates a surface, oils will more easily penetrate the same surface. You can always pick a corner of the granite and put a drop of olive oil on it to see if it darkens.

You can either try it yourself with a sealer from a local store or hire a professional who knows what sealer to use, how to apply it, and will warranty the sealer. Improper cleaning techniques will reduce the life and effectiveness of most sealers. This will allow the sealer to penetrate properly and more deeply for better protection and life expectancy. We never apply any type of topical sealer or treatment to a porous stone.

We have a variety of options for sealing stone inside a home. A simple cleaning, sealing, and polishing process can set you up for peace of mind to keeping these beautiful surfaces looking beautiful.

Help! Granite Seems To Be Changing Color! by

We knew there were pink/orange spots in it but now it seems like all of the cream spots are turning pink too! Would it have been applied after we selected the slab and during the cutting process? Perhaps it is more noticeable with the slab on a horizontal plane, instead of the vertical plane you viewed the slab originally. The manufacturer will need to answer the specifics about what was used.

In the attached photos was a grey spot on the day they were installed, the other is the same spot today just a couple weeks after the install.

I am sure you took a picture when it was put in take another and call the slab yard to the installer. Some of the stones with a lot of movement actually have a mesh that is under them to help prevent cracking as well as a “glue” that hold the mesh on.

Also how long would it take for the changes to start occurring if it was the glue? All they said about all the white turning pink was that it was probably the new temperature in the house. Florescent light fades stuff like the paint on the wall so that might impact your granite. I have never seen stone turn a color unless there was some type of moisture that got under the stone or they used the wrong “glue” to hold it down. The 3 pieces of granite, my island, piece next to oven and fridge and my desk area were all cut from the same slab and they are the areas that are showing the most pink. The absorbancy of the stone will affect the choice of sealant, how many coats and how often it is needed. Soft stones that are light in colour will show stains more so than hard dark stones.
