The last of the preparatory work is reinforcing. It is necessary if a layer of plaster is from 3 to 5 centimeters or if the surface for application is very smooth, or to strengthen complex shapes: if you need to plastered arches, curved walls, angles. That is, the preparatory part is included only if the cement plaster is used. In this case, a metal grid is attached to the base. In addition, between layers of plaster, an additional grid of fiberglass is laid. The grid to strengthen gypsum plaster is pressed into a freshly laid out layer, and this must be done quickly enough.
