STONETECH Enhancer Pro Sealer, 1 Quart/32OZ (946ML) Bottle

This product might be more expensive than what you can purchases at a "Big Box" store, but it is definitely worth every penny! I have a natural field-stone fireplace that was built in the 60's. After having the old mortar re-pointed i needed to use muriatic acid to remove the excess mortar from most of the stones. The acid did a great job cleaning, but left the stones with a dull, washed-out appearance. Enter, DuPont's Stone Enhancer Pro! It brought out the natural color of my stone fireplace with one application (the colors really popped, just like they did when I had washed them and they were wet). It does tend to darken the stones somewhat, which is something to be aware of if the stone you're going to treat is already dark. It also does not give the stones a shine or "wet look" but this was a bonus for me because I didn't want them to have any gloss. The stone enhancer itself reminded me quite a bit of mineral spirits, and it is very watery. I found that a very small amount goes a long way and only used 1/2 of the quart bottle to do my entire fireplace. When applying I used a small 1 inch paint brush and a small plastic container with about 1/4 inch of enhancer at a time. While applying, I had the area well ventilated and wore a respirator, but really found that the smell was not very strong (i am just cautious, so decided to use the respirator). After letting the enhancer penetrate the stone for 10-15 minutes I used a rag to wipe off any excess, but found that if you apply it very carefully and in small amounts, wiping wasn't a huge chore. Even though I did my best to keep the solution only on the stones it did drip and run a bit onto the mortar joints but i wiped them quickly and it didn't noticeably darken the joints. See my before & after picks and see what you think!

Easy to apply to my river stone shower floor and surrounding grout. I did two coats. Definitely brightened the stone and water beads up now as well. It’s very expensive but I felt it was worth it. Supposedly good for 5 years. I have plenty left over and will redo in 3-4 years. Stopping cleaning shower with anything the isn’t PH neutral.

Good product! Just be careful not to mix their two sealers. One is water-based and packaging looks very similar.

I use this product for a few reasons: 1. it lasts outdoors on flagstone (oil-based), 2. the color enhancing properties which contrasts color hues and 3. a little goes a long way. The only negative is the high price, but done once right makes for less labor. Also useful to coat stone after it is set prior to grouting to prevent grout haze. Just make sure to not let it drip into grouted areas, and apply a second thin coat after grouting (days later for full cure).

I had a very glossy and colorful slab of quartzite leathered to give it texture and to tone down the colors. To my surprise, the leathering created a very dull brownish appearance that hid all the beauty of the stone. Based on reviews, I decided to try Stonetech enhancer. I applied 3 coats and with each application the colors of the stone became more pronounced. The enhancer caused the harder, smoother surfaces to have a slight sheen while the deeper more textured surfaces remained matted. This provided a beautiful contrast in the stone. The product is very easy to work with... but as the instructions advise, it's important to wipe it off within 15 minutes to prevent it from building up and leaving a residue. I'm very happy with the appearance of our countertop and will plan to apply this product very quickly and easily about every six months.

I'm really shocked at how poorly this product enhances. Even after three applications it is very difficult to see any difference on honed limestone and Laticrete's Permacolor grout. Finding this result difficult to believe, I used some Tenax Ager alongside the Stonetech on a sample of the limestone and leftover cured grout and the results are night and day different. I've include a picture of leftover grout treated with Tenex Ager on the left and Stonetech Enhancer on the right. Both had two applications a few hours ago. The Ager has darkened the grout as expected, but the grout treated with Stonetech Enhancer looks the same as the surrounding untreated grout.

Have used this product before and it works excellent. Seals and protects travertine from water overtime. Reuse the product every 2 to 3 years. Closer to every two and works better than excellent. Be careful what you buy, this one really works. Have used it on many bathrooms, and have never been sorry. Tries clear. Not a cheap item but sometimes if you wanna deal, you really really get a deal this is not a deal but really really works. One of the better out there!
