Is it necessary to apply a primer before plastering?
A primer ensures better adhesion of the plaster mortar to the substrate. This is especially important for smooth, closed and porous or highly absorbent surfaces. Where plaster mortar without a primer would have difficulty bonding properly. In addition, a primer also ensures even absorption of the plaster mortar, making it easier to strip off the plaster mortar and polish it, sand it or finish it with a trowel.
When do I choose a gypsum-bound plaster mortar or a cement-bound plaster mortar? And can I combine these?
The choice between gypsum mortar and cement mortar depends on the application. Plaster mortar is a good choice for dry indoor applications where a smooth finish is important. Plaster mortar is not ideal in wet areas. Cement mortar is resistant to moisture and extreme temperatures and is a better choice for wet areas and outdoor applications. Cement mortar has much higher strength and is more durable than gypsum mortar.
