Vinyl flooring in outdoor small balcony doable?

[Peter Morgan]

Hello,

I have a small balcony with iron railings on the perimeter rooted in concrete and the entire area is covered with tiles. There is a slight gap between tiles and concrete with some worn off sealant, and I have no clue on how to replace the worn out sealant because I don't know what product it is. I am seeing some water seeping into garage under the balcony so I would like to make sure to tightly seal the gap,I was thinking about removing worn out sealant and pour there some liquid rubber and then on top of the existing tiles I would like to install LVT to fully water proof as well as enhance the looks, is it a bad idea to have LVT outdoors? I am open to other ideas. Appreciate your inputs.

Thanks
