The mixing ratio is 1 part cement and 5 parts sand, and if the plaster is too harsh, 0.5 to 1 part of lime can be added. The wall is first moistened and then the plaster is applied in two coats of about 5mm each, allowing at least 24 hours between layers. Cement plaster should not be applied on a wall while exposed to the sun.

Both Quickrete and Sakrete make a sand mix for topping and bedding, which is primarily sand and cement. You can use such mixes to repair concrete that is no greater than two inches thick and apply it in layers of ½-inch. When using these for a mortar bed, you typically apply them in layers around two to three inches for ceramic tile, for example.
