Plastering over cement for an interior wall

Any advice as to the best way to plaster over a cement wall.  I have a cinder block wall that I was recommended to put a coat of Rapid Set Mortar Mix over and then I would be able to plaster over this.  My first coat of plaster started cracking immediately during "drying".  I was unsure that it would adhere to the cement basecoat so I scrapped it off.  Should I have left it one to dry, scrap lightly, then porceed with a second plaster coat and continue in coating of layers?  Do I need to use another product over the cement coat before plastering?

 

Any advice would be appreciated.  Thank you!

If your fist coat of cement is adhering to the cement block, why not just put a second coat of cement using that as plaster or sometimes known as stucco. A bonding agent would be a good thing to use as an additive when mixing the cement. Stucco can be textured with a variety of finishes, including smooth. If there is any chance of moisture being in the wall plaster would not be an appropriate finish.
