Fibercrete. A smart way to do a pool like this. But it is the final finish not all of the structure. Also a heck of a lot of work. This stuff can set up quickly.

That looks more like tinted gunite than fibercrete
I think that you are right Frank. Looking on my TV I see no fibers being mashed into the cement.Quote:

I am familiar with the product that is fomicolite and cement
Fiber crete has chopped fiberglass or plastic string in it as a replacement for steel bar. It is still concrete. The fiberglass or polypropylene string is added into the mix.Quote:

Guessing that you are in Brazil? That is the only place I could find the product that you named.
Every concrete needs the same conditions. A rough surface that is free of shipping loose old concrete. Free of concrete that is impregnated with salt. To help adhesion there are products that you paint on the older concrete and add to the mix in the new concrete. Concrete bonding enhancement. Usually a polymer of some type. They are effective. Trying to bond new concrete to old concrete without this will lead to a lot of wasted money and time.
Sika is a multinational company whose products I have used. Maybe you know of them. You will need to do more homework as I am not familiar with what you have available locally.
The new concrete mix will require clean washed sand, perhaps small diameter aggregate depending on the thickness of what you are applying. If it a thin layer for cosmetic purposes then only sand and bonding enhancer. There will be recommendation as to how much of this to add to your concrete mix, or sometimes you can buy bags already premixed with al the proper ratios of the concrete. In English we call this a parging mix. Parging is a thin layer of concrete that is applied on top of normal concrete work to act as a cosmetic layer. Make the ugly concrete a little nicer to look at.
