i notice that the white cement is not sticking properly to my ceiling..anyone could advise me on this.. is it due to the surface of the ceiling or i did not blend it properly????
try using plaster works better...
its not sticking because its the wrong material...try plaster...
Use spackling putty from the hardware store.
there is a product use for gibson board call spacking or spackling , bonding agent or something llike that.Apply in the crack and let it dry, it will change color when its dry from pink to white,then you use sand paper to remove excess of bonding or leave it like that.
