Which cement to use and what ratio to mix for making pots

ppp

Hi,  Can anyone please guide me which cement to buy and what ratio to mix ( with water or any other substance ? ) for making pots for flower plants.  Also any suggestions before experimenting with cement projects. 

For example one from this YouTube :   https://www.youtube.com/watch?v=LFUuKo2uBsc

Hi @ppp,
Any sand and cement mix will work well, just add enough water to get the consistency you need to work it how you want to. You could use a concrete mix (cement, sand and gravel) and the finished product will be stronger (the gravel acts like reinforcement, similar idea to glass fibres in fibreglass), but I think you will have trouble working the gravel into your mold.
My two main tips for molding concrete would be to keep it off your hands as it will dry out your skin, and vibrate the mold a lot to work the bubbles out or you'll have pockets in the finished product. Other than that, have fun!
