This product works extremely well. I read a few negative reviews that people had written on this product and concluded that they did not read and/or follow the manufacture's directions. The reason I say this is that when my granite countertops were first installed, the installers only wiped this sealer over the surface then left. I too, had areas that would darken when water would hit the stone, and I wondered why. However, when I applied the sealer liberally (2 yrs later, for the first time since the countertops were installed), allow the sealer to penetrate the surface for 15-30mins (as recommended), wiped off the excess after 30min (which there was minimal, the stone absorbed most of the sealer), and did not use the surface for 24hrs (as recommended. By the way, I took advantage of sealing the surface before I went away for the weekend so that there was no impact to family life.) I had a nicely sealed surface. I no longer have areas that darken when water stands on the stone.
I would recommend this product to everyone.

I've used this sealer now for about 3 years. This sealer rocks. I have 3 different kinds of granite in my house from very hard to more porous countertops, Seagrass limestone shower, walls, and flooring, 2 different kinds of travertine for showers, walls, and flooring, and pebble tile as flooring in my master shower. This sealer really works, unlike the sealers sold in hardware stores like Lowes and Home Depot. Don't use the sealer your contractor uses unless it's DuPont StoneTech BulletProof Stone Sealer. It's just not as good as this stuff.
HOW MUCH SEALER TO USE:
The amount of sealer I've used depends on the porosity of the stone as well as the frequency of re-sealing. See my estimates below.
GRANITE:
My more porous granites need 2, even 3 applications 2X per year. My very hard granite (with quartz) needs 1 application annually or biannually. I follow the bottle directions for granite, and it works well. My kitchen counters (12x12' room with large island) needs 0.5 quarts. One granite bath sink (7'x2') needs 0.5 cups. A more porous granite bath sink (5'x2') needs 0.5 quarts (2 cups).
TRAVERTINE, LIMESTONE, PEBBLE TILE:
For travertine, pebble tile, and limestone, use liberal amounts of sealer. My kitchen travertine needed 1.5 quarts. My limestone shower (7'x4') needed 1 quart. (I have not yet resealed the limestone bathrooms walls or floor that are separate from the limestone shower walls and ceiling.) My white pebble shower floor (7'x4') needed 0.5 quarts.
I pour the sealer from the bottle till the stone is completely saturated (think puddle of liquid for the entire surface) and let it sit. After 10-15 minutes, I look for dry spots and pour more sealer. Unlike the bottle directions, I do not yet spread the sealer. I let the liquid layer sit for 30 minutes. In many spots, the sealer will be completely absorbed by the stone. Starting at one end and working on small 1'x3' sections, I then use dry towels to wipe excess sealer away from my working section, moving the excess sealer about 2" away from my working section onto sections that still are drying with sealer on them. I'll wring out the towels to pour the excess sealer onto dry spots on the dry spots. I continue working on small sections, moving the excess sealer onto dry spots, until each section is dry to the touch. I spot check for any sealer I may have missed.
I then pour a little water on the treated stone. If the resulting water drop are round and don't soak in, I've used enough sealer. If not, I'll re-seal, this time using much less sealer, and this time I follow the bottle directions.
CONCLUSION:
This may not be the optimal way to re-seal stone, but it works for me. This product is good stuff, and I'm completely confident in its effectiveness.
This sealer is about half the price on Amazon, even with S/H, then what I'd pay in the specialty stone and tile stores about an hour's drive from my home.

I have new honed marble counters. Marble is already very porous and when you one it you make it way worse. Everything, even water, leaves a mark. I followed the instructions carefully, and did the full application twice. Since then, nothing (coffee, juice, wine, bacon grease) has left a mark. I highly recommend this product.

I did not realize the granite has to be covered with sealer when I installed new counters and gues what, I put an oil stain on it the very next day. This incident prompted me to do a search on the internet and I found this product recommended by many. I ordered it from Amazone and applied to my counters a few days ago. Application was very easy and so far it works great: no more stains and no "wet spots" from spilled water (unlike oil they dry out eventually). Two things to note:
- a quart is wa-a-ay too much for a 50 sq foot surface. I used probably about 20% of the bottle and I still had to wipe a lot of sealer after second application.
- wear rubber gloves when you apply it. It does not feel like an aggressive liquid, but I did not wear gloves and my skin was hurting after I finished

Our granite is very light and just setting a glass of water on it would leave a dark ring that would disappear after several minutes. The fabricator said this was because it was very porous and that we should not put anything on the counter that may stain it such as wine or coffee. The fabricator sealed it twice but to no avail. We used Stonetech and sealed the granite twice. No more rings! We now put all kinds of food and drink on the counter with no worries of staining. The sealing process was very easy with minimal odor.

We installed a new marble counter / vanity in our renovated bathroom and the marble supply house recommended the Stonetech Bulletproof sealer. We have used other Stonetech products: Revitalizer and Stone and Tile Cleaner, and they have proven to be superior in their results. The Cleaner is fabulous. which we use on our porcelain tile and granite kitchen counters. All Stonetech products are on Amazon. Stonetech notes their products have the correct P/H balance without harsh chemicals like in some supermarket stone clearers, and I trust Dupont in this respect. After 4 years using Revitalizer and Stone Cleaner on our granite it looks like the day we installed it - bright shiny finish and resistive to anything we might 'throw' or drop on it.
The Bulletproof Sealer went on without any issues and the results were fabulous. I had never done this before, so I wasn't sure what to expect. The 'Sealer' penetrates and seals the marble to resist spotting and discoloration, so you have to give it time to penetrate during each application. When you apply the sealer, some areas absorb more and other don't, and remain wet, which is why they tell you towel dry it after each appellation. The process requires a few applications, and Stonetech has clear and concise instructions online. Our counter was 8' X 2' with a backsplash, not very big, so rather than use a paint roller or paint brush (as recommended), I bought (at Home Depot) a square applicator made for edging paint, which includes some helpful rollers, so you can edge right up to wall without smearing the sealer on your painted walls. The pad on the applicator worked perfectly and after 3 applications I followed the instructions and waited just a few minutes for the sealer to dry on the last application and quickly buffed/toweled the sealer to a nice clear shine. If you don't follow this last step, you will be left with a dull streaky finish. For any area that did not buff out completely clear, apply a bit more sealer and buff again. The results were fantastic, and the marble has a nice shine with all of it's natural characteristics of unique veins and coloring. The one issue they mention is that you must let the sealer completely dry before using the area....they recommend 6-12+ hours....I did this on a Sunday afternoon, watched a football game during the applications and by Monday morning it was ready to use. Total application time 3 NFL football quarters, or about 2 hours in non football time.

Used this on a Solarius granite bathroom vanity which was allegedly sealed before installation, but was soaking up water like a sponge. Did two coats, following instructions, and water now beads on the surface (except in one spot that I somehow missed next to a faucet). Quick and easy application, easy clean-up, low odor. Good stuff!

I used it for a new granite countertop. It goes on easily and dries fast. It's been about four weeks since I started using the counter for kitchen work and it still looks new--no stains or dark blotches.
A word of caution: This is thin material and goes a long way so don't order extra "just-in-case" material.

Applied this myself to our new kitchen countertop. I did apply it in two passes but I'm not sure that the second pass was needed. At any rate, it works very well to prevent water, etc from getting into the granite. Water can stay on top for hours without any getting through.

This product is a god sent!!! I just had my Giallo Ornamental granite installed about a month ago. I noticed a stain after a few days (my wife spilled oil on the granite) after the installers left. I was sick, thinking my granite was ruined. I purchased the Oil Stain Remover, (Tech EX6-16 1-Pint Oil Stain Remover for Natural also from Stonetech) also for sale on Amazon, to get rid of the stain. Once I removed the stain I sealed the granite with 3 coats of the Bulletproof Stone Sealer. Once I was done treating my granite I tested an area by putting a good amount of water and let it sit for a few hours. To my amazement, the water pooled up and sat there like a waxed car and never was absorbed!!!! This product actually works :)
