Finishing walls with plaster is the mosta common way to make a surface more even. Although such work is long, laborious and requires concentration, even a completely inexperienced craftsman can master it. Here the main task is a thorough study of the theory with its subsequent application in practice.
Finishing walls with plaster is one of the ways to make their surface more even.
Types of cladding
There are a great many classifications of plaster, but one of the most common is the specification by area of application. Facing can be of the following types:
The usual plaster mix isa semi-finished product that must be brought to readiness before use. This type is mainly used for finishing walls before painting or wallpapering. Regular plaster can be simple, high-quality and improved, depending on the quality of the work.
Plastering building mixtures.The main function of a special coating is to protect the walls. It can be a waterproof type of plaster or heat-insulating. Decorative cladding is used when finishing the interiors of rooms or the facades of houses and other buildings. It allows you to make the surface relief, of different textures or colors. For each of the options, there is a separate type of material. When choosing plaster, it is very important to decide on the type of surface that needs finishing. After all, brick walls require a large amount of facing mixture. This is the main reason why you should opt for a solution of cement and sand. Concrete walls and other smooth surfaces can be plastered with a gypsum mixture, having first carefully treated them with a primer. Return to contents</a>
Wall Preparation
When simply covering the surface with a solution withoutpreliminary preparation of the walls you will get a not very pleasant sight. Even small waves can ruin all your work. The only way to avoid this is to prepare the surface according to all the rules:
Wall plastering scheme.When leveling the surface, remove all unnecessary fragments on the walls. This applies to both the burrs on the brick or concrete and the old paint coating. It is also recommended to carefully level the seams between the bricks. The next step is to prepare for setting the beacons. To do this, drill holes in the corners that are located on top and screw screws into them. Using a building level, determine the most protruding areas of the surface. Then screw in a screw in the lower corner, having measured a strict vertical beforehand. Repeat all the steps in the same order at the other end of the room. After this, stretch threads between the upper and lower marks, along which new screws are screwed in. The gaps between them should be the same. After completing the work on marking the future beacons, you should start priming. The wall surface is thoroughly cleaned so that there is no dust left after drilling. Apply the primer with a roller. If you are dealing with a brick wall, the coating should be made denser to hide the unevenness of the seams. After drying, we proceed to installing the beacons. Between the vertical marking lines, we apply a little plaster, into which the beacon is attached. After installing all the profiles, they should be carefully covered with mortar. The last stage of preparing the walls is their alignment. For this work, we use a mixture of sand and cement. It should be noted that a thicker layer of plaster requires large sand fractions. With a large amount of cement, the solution dries faster, but such a coating is not very durable. Return to the table of contents</a>
Finishing of walls with plaster
On the question of correct alignment of wallsplaster there is no clear answer from experienced craftsmen. But after careful preparation of the wall surface, there is nothing complicated in this process. Finishing with ordinary plaster consists of a primer and leveling layer, followed by smoothing them. The first stage is performed using the spray technique. It is characterized by throwing small portions of the solution into the wall with strong and clear movements. This method allows the plaster composition to adhere to all the unevenness of the surface. The entire gap between the beacons is filled by throwing. This rough finish does not require additional leveling.

With low beacons and a more even surface, this option is quite acceptable. If the coating is below the level of the profiles, then the work done should be repeated again, having first treated the bottom layer with a primer. Leveling plaster allows a brick wall to acquire all the properties of a concrete one. It is much easier to work with. When the solution begins to dry, you should start leveling it. For this work, you will need a building rule. The tool is applied to the beacons, which are located below, and with some effort moves upward. The coating is considered completely even when the ribs of the profiles appear on the surface. Now all that remains is to wait for the mixture to dry completely. After the plaster coating has hardened, it is necessary to remove all the beacons. If they are left in the wall, then over time you may encounter some problems. The fact is that the plaster absorbs moisture, and this circumstance can eventually lead to corrosion on the profiles. There is a risk of rust passing through the wallpaper or decorative plaster. To avoid such phenomena, all beacons should be removed. Using a spatula, the coating is cut along the base of the profiles, and they are removed. Sanding the walls will complete the entire process. It is carried out using a special grater. It is necessary to remove all irregularities with circular movements, thoroughly wetting the walls. After this, the surface is suitable for painting or wallpapering. Return to contents</a>
Facing with decorative plaster
Before starting the finishing coat, you shoulddecide on the type of final wall finishing. Venetian plaster requires an absolutely smooth surface. And for textured or relief, less thorough preparation is quite acceptable. An ordinary flat wall will do for them. Decorative coating is quite an expensive and labor-intensive process that requires effort. If you decide to do without the help of specialists, then there are many simple options for such finishing. The most budget-friendly way to apply decorative plaster is to use a roller with a pattern. For the work, it is recommended to use ready-made mixtures, which are abundantly available in any hardware store. You can apply the coating directly with a roller or in the usual way with further beating off the pattern. Additional painting of the walls will help emphasize the depth and beauty of the relief. In addition, in your work you can use a special comb or trowel with teeth for applying patterns. This method will allow you to realize all your fantasies. Some craftsmen use sponges and plastic bags to get a relief surface. If the use of special tools seems too complicated for you, you can use ready-made plaster with its own texture.
