It works in my shower.
A friend recently updated my bathroom and installed this rock/pebble tile in the shower floor. He must have used the wrong type of grout, or he applied it incorrectly, because it was coming up in chunks when I showered. I also noticed cracks developing between the pebbles. I was afraid I would have to rip up and redo the entire floor. Ugh! I was looking for an alternate solution and I found this waterproof sealant. Another reviewer used it on her pebble shower floor with excellent results after several months, so I tried it on my shower floor. I followed the directions and applied a total of 4 thin coats to the entire floor and waited three hours drying time between coats. I then let the floor cure for 78 hours. I only used 1/2 jar. I’m very pleased with the results! No more loosening chunks of grout and I’m confident the cracks are well sealed so there is no water seeping under the pebbles. Unlike the other reviewer, my floor is not slippery at all. And you cannot see the sealant. This jar of sealant saved me a ton of work (and money).

Little extra work for a perfect resolute
This isn't a one coat and you're done. Follow the directions and you won't be disappointed. It's a little time consuming, but if you apply a very thin first coat and let it fully dry before applying a thin second and third coat, you'll be pleasantly surprised. Lesson Learned!!

Would not work for area that water would be pooled in, like a pond or something.
I love those product! It saved me a huge task! We have this tile shower that I love. It had started to separate through the base despite following directions to a t with install, using waterproofing products before installing tile ect. I could not , for the life of me figure out where it was seeping. So in a last ditch effort to save it before tearing it all apart and just going with a shower pan and stall, I decided to try this. It took about 3 weeks to make sure everything was completely dry below( we have full access to the underside in the basement too) I took about a week to apply 4 thin coats, completely drying in between each coat. There is no more seeping and it looks great! Now if there is any buy that pools even slightly with water for extended period of time, it will turn milky, hence my comment in the title, but it goes away with drying. It is a bit slippery at first but we use a rubber mat when we shower. I figure one coat additional a year will keep it good. It has been 6 months since i did it and it is still doing great. Keeps that grout clean too....

Stopped the roof leak!
Had a leak in the sunroom dripping water on the ceiling fan. Applied two coats on the roof seam a month ago and no more leaks! Will do the rest of the roof seams when winter passes.

There is a difference result other than the ads
Saw this product in ads. Bought one for trying. It does easily apply and use. So to buy the 2nd one. After one week after applying, the result is the applied surface is not hard as showed in the ads. It's more like a rubber surface. And also it is not good for vertical crack. The filling will not stay. It will drop down. This is not what I hopeful.

Bought this to seal some cracks in the balcony floor, at the hidden corners. Was expecting it to be very messy and difficult to work with like translucent silicone bathroom sealant, but this was not the case. It is much thinner in texture, runny and very easy to apply with a normal brush. It appears white opaque in the pot, but when spread out it dries clear and invisible. Very easy to apply several layers, leaving two days between. I have also used it on Upvc widow frames with great results. Another bonus is that it is water based and just needs washing in soapy water, so you you won't lose a brush every time you use it. All in all, an excellent product that delivers completely on its promise to seal cracks .

Il prodotto si presenta denso, facile da dare con un pennello,io lo dato su un davanzale in pietra già verniciato per ora sembra che funzioni bene,si è asciugato in fretta,ma in questi giorni fa caldo, tutto questo ad Agosto. Oggi 7 ottobre né ho preso un' altro barattolo perché il primo è finito dopo aver fatto una panchina in legno,ora ben sigillata e il sotto di una scala in cemento con una crepa anche questa sigillata e l' acqua vi scorre sopra senza fermarsi.👌👍

Fabuloso para sellar y reparar fugas de agua entre pavés de vidrio sirviendo de claraboya. Después de sellar las juntas, pintado con el impermeabilizante transparente, dos capas en doble sentido!
