Do not believe those who say that grinding the walls is an unnecessary stage in the repair process. Workers, approving this, are either very lazy or amateurs. Do not ignore this process yourself and do not let it be different.
Place the walls - the occupation is not simple, especially for newcomers. But it's ideally smooth, it doesn't even get the masters. Therefore, grinding of walls after putty occupies a special place in the process of repair even with them. In this article, I want to tell about how you can bring the wall to the perfectly smooth condition.
Fashion selection - dry or wet
Apply to the wall putty, you, anyway, leave various blots on the surface. It can be furrows from a spatula, mixes of mixes, tubercles, waves, etc. Naturally, not worth leaving them and moves to the next stage of work. Therefore, such shortcomings are cleaned after complete drying of putty, usually coming around one day after its application.
And here there are options for how to do it. Immediately make a reservation that the grinding process is quite dirty business in the literal sense of the word. Therefore, take care in advance that the subsequent cleaning is minimally laborious. So, grind the walls can be wet or dry. In the first case, water is logically used, there are no in the second. What is the difference and what is the way it is better to choose?
Wet grinding is appropriate for relatively smooth surfaces, such as drywall or wall, plastered a rule. Also, such grinding perfectly cope with the elimination of scratches and small waves. And the main advantage of it, of course, the relative purity of the process will appear.

The fact is that you will not see dry dust, which means that the air and the surrounding furniture will not be filled with it, and the subsequent cleaning will not take a lot of time and effort. Dry grinding is associated just with the formation of a large number of this dust itself and it is its main disadvantage. However, it is not necessary to do without it when the wall turned out with folds, tubercles and drowshes, or was not previously aligned.
Tools and consumables
In order for the wall to acquire a smooth surface, you need to be armed with ordinary sandpaper and wooden bars or a special grinding machine. Immediately make a reservation that the subsequent decoration will play a decisive role in the grinding process.
For sticking vinyl or phlizelin wallpaper, the wall does not have to stay perfect smooth. It is enough to remove large irregularities, bugs, glances. But under painting the wall will have to prepare more carefully.
This is due to the fact that water-based acrylic paints highly distinguish the slightest shortcomings, especially when it comes to light colors. Tight oil-based paints are able to hide small irregularities due to their density. However, it is also not worth hoping for such an option, since the concept of the degree of smoothness often remains subjective and does not coincide with the possibilities of paint.
Grouting with a dry way will pass faster when using an electric tool. But the high-quality machine is expensive and its purchase with small amounts of work is economically absolutely unprofitable.
The cheaper option will not give the desired result, and you will still have to do any equilion. Emery paper will need a lot, as it is quickly clogged with dust, especially if it is too small. Larger will leave extra scratches.
Ideally, I recommend it to carry out an opening, using the R60, P80, P100 labeling. Also, do not forget to cover all the furniture, armed with a respirator and headdress, and under hand have a wet rag. Remember that the putty will turn in the air in the form of a large amount of dust. Doors in adjacent rooms tightly close or coat with a wet cloth. Wet grout will not require so much preparation and it will be possible to do the bucket with water, a grater and a wide spatula.

Grinding technology
Grinding technology is shown in many videos. With a dry way, an excess putty is removed by sandpaper, wrapped around a wooden bar or a grinding sponge with circular or longitudinal movements.
The wall is broken down into small areas and thus passes completely. Plus, manual grinding is that you can get to all complex places, such as angles, where the putty fell especially unevenly. With the help of a grinding machine, this will be done quite difficult.
With wet grinding, everything is much easier. The wall is moistened with water, the putty swells, and you can ride it with a grater. Surplus, which will appear in the form of divorces, are removed by a wide spatula in the same movement as when plastered. Thus, the spacious putty is a thin layer as it can be sprinkled over the surface and fills all the scratches, and small glances are diverted.
The spatula is cleaned with a rag and is ready for further use. As a result, the wall remains perfectly smooth, and putty, without forming dust, remains on the places put it. As you can see, with all its importance, the grinding technology is quite simple. You can make sure that you can see the various videos and starting this process yourself. And whatever way you have chosen, let your repair get easy and chic.
