I used it on the underside of an outdoor waterfall to prevent undercurling of the water, which was letting it spill over the lower rim and out of the system, 1st pic. It may be hard to tell from the pictures, but it falls straight down now, 2nd pic. I was kinda careless on the first spray, and instead of rotating the bowls to apply, a bit of over spray ran into the lower bowl interior and you can really see how effective it is with just one application, 3rd pic.

I have a highly porous travertine roof top deck, which if not sealed leads to leaks below. As a result I have to seal at least twice a year to maintain roof integrity. Over the past 4 years I've used several different sealers with this being the most recent.Firstly, it's close to odorless. I've used silicone based sealers in the past which stank to high heaven, but not this one. That's a plus.Second, the applicator they include is mostly suitable for the job. They estimate one gallon per 1000 feet but it's closer to 2 gallons in my experience.Third, after some recent rain I was happy to watch the water bead and sheet off as desired on the finished areas. I'm sure I'm going to have to reapply it in 6 months tho, mostly due to the weather extremes in Florida we get (heat, rain, wind). That's ok.I'll update if my opinion changes in a few months.

I had a water leak seeping from the Top of the Window frame edge when it rained for a week! I sprayed the outdoor Patio Wall on top of the Window Frame and next time it rained for several days in a raw, there was no water leak seeping inside. It does actually repel water making the sprayed surface Hydrophobic. Hope it can last for 12months before i have to re-apply.

Este producto solo dañó la lápida de mi bebé era nueva y negra y yo quería que no se le manchara con el agua y el producto me la manchó toda ahora se mira con gotas del producto y no las puedo quitar si repela el agua pero el producto dejo opaca y manchada la lápida y antes brillaba😭😭😭

I applied this solution to a white limestone ledge on our outside fireplace. It goes on easily and when it dries you cannot perceive a color change or a texture change so basically it is 'invisible'. However, when you pour water on the treated area there is no absorption of the water. It simply beads up on the surface. On vertical surfaces the water runs off and you cannot tell it was even wet.I think this product works very well -certainly in the short term. I'll have to watch it over the next several months to see how well it tolerates the heat and the weather, fallen leaves, bird poop etc.. I'm hopeful that it lasts a very long time. I also think that the amount of coverage advertised is on the high end. For a porous stone like limestone it requires a more heavy spraying but in the case of dense granite, it might well cover the advertised area.I will report back to update on the durability of the product.

Easy to apply and dried in 2 hours. Made a second application to increase protection and the look was perfect. Excellent quality and performance.

The Nano Stone Sealer is easy to use and works great on granite, marble and Italian floor tiles.

Cover well. Water resistant
