Excellent product that works.
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 .

Sealant
The sealant is very easy to use and does the job. It is nice and thick but usable. I have used it on three different items and have plenty left therefore, worth the money.

Expensive but ok
Product is very thin but did do the job to a large extent. Overly priced.

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).

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!
