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. 

Never simply apply a cement-based plaster mortar to a plaster-based surface. Use specially suitable plaster mortars, such as our 90GR omnimix, W100 R omnimix or W100R LIGHT omnimix.

What is the drying time of omnimix plaster mortars?

The drying time of Omnimix plaster mortars varies per product. We have normally hardening and fast hardening plaster mortars. You can recognize the fast-hardening plaster mortars by the R in the name. Under ideal conditions, these can be tiled after 3 to 4 hours. For a finish other than tiles: Always follow the processing instructions.
