RedGuard is a specific product only to be used under tile installation.

Hi Midalake,

Do you know where the redgard might be found in Mexico. Or should I contact the US based company? and see where they distribute it here. It sounds like the product we were hoping for. Our architect and builders were very in tune to giving us the proper slope and drains to get the water off the roof..and from the rains we had...it has worked. Now is time to decide which product to use. Someone had suggested a black tar like substance they use to seal the cistern...but we thought there must something better.
Thanks for your answer.

One other thought. Make sure your tiles are rated for outdoor use and are Mfg. of quality [porcelain]! One person made that mistake, and it was not pretty. Since we just finished our remodel, I recommend Castel Tile. There is a small distributorship in town just past Bodega going to Ixtapa.

I have not used it but friends in our building have. I would check with you builder and architect. They can make the calls. Stuff is not cheap though.

Looking for the smartest way to finish a rooftop patio so it doesnt leak but is also nice looking....
we are debating between the rolled waterproof sheets that look kinda like the material of asphalt shingles...or painting on a waterproof tar looking or ruberized liquid and then laying tiles on top. we prefer the idea of tiles as they would look better than the asphalt looking membrane. Does anyone have any experience with these options> Which works better...looks better? Long shot here!

There is a product called Redguard. It is available in Mexico. ONE AND DONE, until you need new tiles.

Lots of research can be done online with this product. The only thing I would add is, get some grade going to the roof. In other words, not 100% flat. Ponding water is a killer of everything. Not sure the size of your space but a 2% grade should do it!

Concrete rooftops have to be waterproofed periodically in the tropics. If you lay tiles on top of it, you'll only have to remove them to re-waterproof your rooftop. We place sheets of tarpaper then paint the roof with impermabiliazante.
