Screed plaster for walls

Plaster is a special type of finishing material whose composition and application method depends on the desiredgoals. So, if you want to make the wall smooth for the finish lining, use leveling plaster. On it is convenient to glue wallpaper, put tiles or apply decorative plaster compositions. They often contain

solid particles, pigments and various additives to create an original effect.

Any finish begins with the leveling of the walls, and often you have to use a special plaster for this, because it allows you to hide the obvious surface drops. Moreover, the leveling composition improves the performance of the floors and occupies a minimum of space, unlike gypsum boards.

To prepare walls in this way, use a cement-sand or gypsum mortar - the choice depends on the material of which the wall is made. In order for the heavy cement mortar to hold on a vertical surface, it needs support in the form of metal profiles and reinforcing mesh. Gypsum is much easier and firmly attached to the wall without additional support. However, this plaster is not recommended for use in rooms with high humidity, so if you are going to choose its for a balcony, make sure that it is securely isolated. In general, gypsum prunes are used for finishing finishing with a layer thickness of not more than 20 mm.

Specific work with

The leveling of walls with plaster can be divided into three stages: preparation of the wall, preparation of the mortar and proper application of it to the surface. To prepare the wall, you must remove the old coating. It is best to finish the balcony with plaster immediately after the installation of hydro and thermal insulation.

If you work with a "bare" wall, then on a smooth concrete surface the mixture can not hold tight, so you need to make its rough - put jags or small chips. For this purpose, rigid steel brush or ordinary chisel is usually used. For reliable plaster setting, any wall must be covered with an adhesive primer of deep penetration. Before applying plaster, the wall must be soaked that all the water from the mixture is not absorbed into the brick or concrete. Also the surface must be to dust and wait for the complete drying of the primer.

Prepare the plaster mortar strictly according to the instructions on the packaging to avoid unpleasant surprises. You do not need to mix too much immediately - you may not have time to use it before hardening( especially plaster).Thoroughly mix the composition so that not a single lump remains. To ensure that the surface is perfectly flat, guide rails are used. They set the desired plane and do not allow the plaster to fall off. Such beacons are installed at a distance of about 50 cm, and then hide them under a layer of plaster.

The first time anyone can not create a perfectly smooth coating, but do not worry - after 2 - 3 hours after plastering its can be rubbed with sandpaper, thus hiding the in defects. According to the technology it is necessary to adhere to the of a certain layer thickness, therefore measuring instruments are useful for work. Over time, it will get to do "by sight", but main - remember that the thinner the layer, the better.

Another one important mote nt pr and work with cement-sand plaster - reinforcing mesh. It is needed in order to improve the rigidity of the wall and not allow the plaster to collapse under its own weight. When purchasing, please contact the retailer that the mesh is for indoor use only. Attach the of its to the wall with the same solution and lightly heat in it .

Helpful hint: To ensure that the plaster does not fall off, apply a few thin layers of , letting dry completely the previous one. In total, the coating should not be thicker than 30 mm.

Alignment with plaster

If you first do the plaster of the balcony with your own hands, better than use a wide spatula - apply the compound to the wall and stretch it from bottom to top .Trowel is also designed for this, but with it you need to be able to handle to make the surface smooth and beautiful.

Working with brick walls

If the walls on the balcony are made of bricks, so that the plaster holds tight, first clean the seams to a depth of 8 - 10 mm. In truth, working with brick and block walls is a bit more complicated than with concrete ones. The fact is that the that the bricks have a porous structure that absorbs water very quickly, and there is a risk that the plaster will crumble and swell. For this, at the preparatory stage, the wall must be covered with 2 - 3 layers of adhesive primer.

Important: If the house was built quite recently, it is not recommended to putty the walls - the building will necessarily give a small shrinkage, and all your efforts will be wasted.

The plaster layer for the brick wall must have a thickness of at least 10 mm. Be sure to reinforce it with reinforcing mesh, as it helps to level the surface. To protect the plaster from cracking and deformation, you can use a conventional paint net. This is especially true in places near the door and window openings .

Let's briefly describe the technology of plastering a brick wall on a balcony:

  1. Strip the seams.
  2. Cover the wall with a primer in 2 - 3 layers, waiting for the complete drying of the previous one.
  3. Apply a bit of the plaster mixture and dump the reinforcing mesh into it, attaching its cuts overlapping the to 10 - 15 cm.
  4. Wait until the holding layer completely dry.
  5. Apply the leveling layer to the guide rails and beacons.
  6. Wait a few hours and wipe the surface defects with sandpaper.

As you can see, there is nothing complicated in this, and the plastering of the walls on the balcony can be an excellent practice for repairing in the apartment itself.
