Microcement  

So apparently nobody has experience with this? Well I will give it a go at another forum and otherwise talk to a pro about the result.

I made a post in order to answer you... hahaha im going to paste here:

I have a flat where I put microcemento, I take the instructions of www.latiendadelmicrocemento.com I ordered the material in the web site and I start working on my own, and for the price I paid it was worth it, now I have seen that even i can made furniture works, so I go experimenting.

i hope this information can help u, and if you need something else, we can talk 😀
