Wall plastering

Laying on plaster on walls for smoothing and preparing them for further processing is considered to be "wet" method of plastering. It can be done both by mechanical machine and manually.

Manual plastering is carried out in the following steps:

  1. Preparation of walls - cleaning the surface of old coating and wetting it directly before applying the mix.
  2. Installation of corner beads and fixing metal profiles. This step is necessary to get perfectly smooth walls.
  3. Preparation of plaster mix.
  4. Plastering the walls, which consists of several stages:
  5. Applying the mix on the wall surface;
  6. Skimming the plaster layer;
  7. Removing excess of plaster within 1 hour after it starts going hard;
  8. Interval between laying the coats should be 2 to 8 hours (depending on the materials used).

Manual plastering of walls is applicable for small areas and zones with lots of curved elements (arches, niches, columns). Optimum condition for plaster application is +5° to +30°C with acceptable humidity level of 60%. It is also important to follow the manufacturer’s rules and recommendations regarding preparation of plaster mix.
