The finish putty plays an important role in any repair work. This material allows you to prepare walls with the least cost for the final finish – staining or gluing wallpaper. However, in order for your walls to acquire an ideal appearance, you need a certain dexterity, patience, a clear adherence to the instructions and knowledge of the properties of the material with which you work.
Types of finish putty

Select putty on the basis of the type and location of the room. Mixtures are:
For external work;
For internal work.
Facade putty is made on a cement basis, which gives the coating durability, strength and resistance to adverse atmospheric influences. However, such mixtures can be used inside, for decoration of rooms with high humidity – kitchens, bathrooms or pools.
Placse -based puttys are designed for living rooms. They are distinguished by remarkable adhesion and plasticity, after drying they have white color, and are also easily polished.
Recently, polymer putty has gained wide popularity. They have a number of advantages: they create a perfectly smooth surface without cracks and shrinkage, in the prepared form they can be stored for quite some time. The only drawback is a fairly high cost. This type of construction mixture is great for walls and ceilings, which are subsequently planned to be painted, as well as for rooms with a high moisture level.
You can buy putty in two types: dry and ready. The advantage of the first type is that a dry mixture under normal conditions can be stored for a long time, while ready (especially if it is already open) begins to dry out over time. However, the dry mixture must be diluted with water in strict accordance with the proportions indicated by the manufacturer on the package and use it quickly enough. The slightest deviation from the norm, as well as if the conditions in the room do not correspond to the temperature range of use, can violate the astringent properties of the finish line, and the result of the work will be of poor quality.
The finished putty does not need to dilute with water and knead thoroughly. And working with her is much easier than dry. It is more economical: the remnants of the mixture for a long time can be stored in a tightly closed container. But it is more expensive in the purchase, so it is better to purchase it for surfaces for painting (where you need to get the perfect result).
Application of the finish

To begin with, it is worth noting that the peculiarity of the use of the finish line is that in front of it the wall should be leveled by the starting construction mixture. Significant irregularities and disadvantages that finish putty simply cannot be eliminated on the processed surface. The estimate structure of the finish line is designed to apply the mixture with a thin layer on a flat surface. When deepening deep holes, the mass will give a large shrinkage with the appearance of cracks, and when laying a thick layer on a large area, it can simply “swim”.
Before starting work, to the surface treated with starting putty, you need to apply a primer. It will strengthen the base layer and will prevent the rapid absorption of moisture. That is, work with the finish will become much easier. It will be possible to apply the layers slowly, and in case of error – calmly fix it.
It is also worth taking into account that the thick layer of the finish line is very poorly “obeyed” and it is quite problematic to correctly distribute it. There may remain irregularities, bubbles and furrows on the surface, which, after solidification of putty, will be very difficult to comb and give the wall a “divine” view.
Since the finish layer is very finely dispersed, dust forms when it is wiped, which literally “hovers” in the air and has a very unpleasant feature to penetrate literally into all corners. Therefore, doors to the room where work is carried out (especially in the case when the repair is done gradually) should be tightly closed.
Subtleties of using the finish
The surface before using putty should be cleared of dust and dirt, leveled and primed.
Strongly dry (or dirty) walls or ceilings will instantly absorb water from putty, and it will become almost impossible to work with the solution – the mass will move after the spatula and fall off the surface.
Put their putty with a wide spatula in measured, confident movement. Remember that the change in speed will lead to the formation of the waves, and you will have to remove the newly superimposed layer and repeat everything again. The thickness of the layer should not exceed the thickness recommended by the manufacturer (usually 2-5 mm). But even if you do everything right, tears and bubbles can occur on the just applied layer. You can eliminate them by typing a little mixture on the spatula and smoothing out places with defects.
One of the most important collisions of successful work with the “finish line” are absolutely clean tools!
After each movement, you need to shift the remaining putty from the spatula to the spatula, t. e. mix it in this way. A frozen mixture will accumulate on the reverse edge of the tools, which when it hits the processed surface will reserve potholes and inclusion from denser lumps. Therefore, from time to time, the tools must be carefully cleaned or washed.
