Finishing the plastered surface under the sticker decor or Wallpaper has always been the most difficult and important process of obtaining a smooth and flat wall. Not always have the courage and patience to do the finish plaster walls with their hands, often have to engage a specialist, but practice shows, even such delicate operations can perform with their hands, if there is the will and desire.
Methods of deducing the geometry of the plaster walls in zero ↑
Under finishing plaster understand the state of the surface, upon reaching which wall to paint, whitewash or tighten the liquid Wallpaper. After laying the ground and the base layer of plaster due to shrinkage and a high grain surface at best resembles emery cloth medium grit.
If primed and painted a plaster – on a plain surface immediately manifest the curvature and the roughness of the walls. The finish plaster walls gives you a nearly plain and smooth background, especially if you paint long paint roller.
To bring the surface of the walls with your hands in several ways:
- With additional coats of finish plaster;
- Repeated priming of the «failed» and uneven parts of the surface;
- By cutting your hands «cones» and «humps» with emery, if the operation you performed on the stage of the alignment base layer plaster.
It is clear shown in the video
Even if all the operations made by your own hands, correctly and on time, there is no guarantee that after drying, some of the micro-layers of plaster does not pop up or will shrink, breaking the derived geometry. Such processes are not uncommon, especially when non-uniform drying of the plaster.
All operations equally successfully applied in finishing operations, but since, in addition to the normal geometry of the walls, we need the hands to get the required surface texture, the main focus will be the use of special mixtures for the finishing plaster.
What materials to work on finishing the walls ↑
If you have plenty of time, and have a desire to experiment, you can try to find the optimal composition of the plaster mass for the application of a finishing plaster with their hands. This will require sifted quartz sand, very fine, almost dust-like fractions, cement 400 grade and a small amount of polyvinyl acetate glue.
Why is it necessary? The vast majority of cases, the finishing compositions allow to obtain smooth and even surface of plaster, but frequently this finish is a part of, or basis for decoration or liquid Wallpaper. In this case, especially if the decorative plaster is translucent and shines, her appearance is partially affected by the color and texture of the finish wall. In some cases, for a specific opalescense or marble pattern in the composition of the finishing plaster can be added to ground glass, calcite dust, different colors.
The alignment of the walls finishing ↑
If you have «proven» the seller of dry building mixes, buy a couple of bags of finishing or superfinishing compositions for plastering and the amount of acrylic primer. It will be more reliable experiments with his own recipes. As a rule, data on consumption of dry plaster mix to the square indicated by the manufacturer. Do not forget to check the date of issue of the mixture and its purpose is for internal works.
Print wall finishing composition ↑
If the main layer plaster has sufficiently dried and partially gained strength, check the condition of the walls using the old instrument rules. To do this, follow a few simple procedures:
- Attaching the working surface rules to the old plaster, consistently check the presence of failures and «humps» on its surface, the problem areas to note in pencil;
- Particularly large «crusts» carefully take out your trash Unsharp tool or sandpaper medium grain, after that, perform the check again;
- Note the border and the deepest curves of the squares of the wall;
- Will saguntum the wall surface of the acrylic composition.
This can cause cracks in the plaster layer. A similar technique can be used for one hour since the end of the alignment of the basic plaster layer.
Working with surface finish of plaster ↑
Kneading part of the finish composition to a thick cream, apply the plaster on the curves, and failed plots, intensively rubbing the mixture with a spatula from the center to the border region. Next, we use the more liquid finishing mortar of plaster is applied sequentially from bottom to top on the wall. The average thickness does not exceed 2-3 mm.
By soaked the ground floats lightly equal the problem areas and proceed to the most responsible stage – the alignment.
The main problem with the finish formulations lies in the weakness of the solution. When the thickness of three to one millimeter deposited liquid layer is more or less aligned. But after 10-15 minutes the sublayer «black» plaster will absorb water, and finish the composition becomes viscous. When you try «stretch» mixture over the surface it will «break» and Stripping old «draft» Foundation wall.
For more accurate work it is necessary to act rule a little differently. The tool does not pull on the surface finish of the mass, and as the series presses small steps in the direction of the wall edges. The depth of pressure and stress is quite small, you can alternate pressing with a small cylindrical mass.
Coat of finish mass collected by the rule along the side surface are immediately removed from the tool with a spatula and rapidly grind to «Falcon» or wider spatula. Then the resulting surplus is sent to less responsible positions in finishing.
Grout ↑
Unlike other operations, the grout or smoothing the finish of the mass, it is important to be able to dose the force applied to the tool. If finishing the solution began to thicken on the wall, razravnyat help very small rotational motion. The surface of the wooden floats must be lined with a very smooth plastic or polished piece of steel. And, don’t forget to moisten the surface of the plaster and grout tool.
Conclusion ↑
To assess the quality of the finish the walls in «fresh» the form is very difficult, sometimes only after the first coat of paint defects manifest as surface. So do not rush to assess the level of finish on the first results of work.
To get a perfect surface of the walls is very difficult and not always necessary to try to achieve all the goals with just finishing. Even experienced craftsmen often use putty to eliminate minute scratches or grooves, but it should be done after setting finish weight.
