Can anyone recommend a silicone for around white quartzite where it meets wall that will not bleed into Calacatta Lux Quartzite? It is installed and the edges were not sealed. any help is greatly appreciate to be able to avoid these problems. We had a little silicone bleed one the one piece they sealed and acetone removed it. I want to avoid this, and ESPECIALLY these slow bleeds that take awhile to show. I want to put up tiles but not before I can test a good silicone for the edges and wait a few weeks. Thanks so so much in advance!!!! It is quartzite and passed all the tests, but when I learned hardness and porousity are two different things, it was already installed - came across this looking for maintenance and care.

Wanting to add to this thread that we got the Matarazzo quartzite in our newly remodeled kitchen 10 months ago and we are loving it!!! We have found it can* etch and have two spots that have come out. Once from a wet wooden cutting board, used as a drying board and caused the wood to leave a stain. That was my fault. Got it mostly out with baking soda trick. Another one was a missed left over drink spill that wasn’t wiped up possibly something acidic. But we still love the live stone look. It’s something quartz can never ever have ; the unique look and feel is something special. Every time I wipe it, i fall in love again! It does have stronger variations in some places but with our neutral style, it was the right amount of interest for the overall kitchen look.

Fsal, that poultice works pretty good for oil stains. I tried it a few years ago on my carrara (before it was properly sealed). made the paste and covered it with a moistened paper towel, and then the plastic wrap. left it for a day or two. it does draw up the oil. you may have to repeat. They also sell these poultices ready-made (search "marble poultice") for stains. ILoveMod quartz is man-made. quartzite is natural. (quartzite is made of natural quartz but it's called quartzite). as for the resin, cheaper quality quartz may use a cheaper resin/materials. The most common yellow stains on any quartz brand countertop are the following; 1) General yellowing to the entire quartz surface due to build up of salts & surfactants 2) Around under mounted sinks - due to salts & surfactants in dish soaps. High pH 3) high use & cleaned area. 4) Under coffee machines 5) under pot plants on the quartz countertop 6) under dish mats or drying mats near the sink 7) under fish tanks. All of the above allow the salts & surfactants to form and generate the quartz countertops causing the yellow or light brown staining. As you will notice that UV light does not generate dish mats, under fish tanks and also pot plants. Whilst UV light can accelerate the yellow staining to white quartz countertops. IT IS NOT THE CAUSE! (they even mention high humidity and relation to salt water as contributing!)

I’ve been in the stone restoration business for over 20 years and have seen many other solutions to keep marble counters from etching over the years. The MORE AntiEtch treatment is the first one that actually caught my attention because on most stones, it maintains the look and feel of the stone and doesn’t look like plastic sitting on top of your marble counters. When there are complaints about this product, it boils down to 3 problems: 1) The contractor not advertising accurately and setting proper expectations 2) If the contractor did explain the benefits and limitations, the consumer not paying attention and just thinking that the treatment will make their counters ”bulletproof” 3) Poor application/finishing by the contractor The product itself does exactly what it is meant to do when applied and finished properly. We always explain the benefits and limitations of the AntiEtch product to our potential customers, including providing them with a copy of MORE Surface Care’s AntiEtch Care and Maintenance Instructions and a copy of the Warranty to be reviewed before even approving the work to be done. I feel that all AntiEtch authorized applicators should be very clear about the fact that the treatment will stop etching, but it does not stop scratching, scuffing, etc. Etching is the main eyesore on marble counters, and this product eliminates that problem.
