What putty to choose, you need to decide specifically for each object

You can answer the question, which medicine is the best?

We think it’s unlikely, since there are no universal remedies, and different diseases are treated with different drugs, and in advance they are well-tolerated by patients. A similar answer can be given to the question which putty is better: the one that suits you in many ways, and first of all, by appointment.

Types of putties

To understand which putty to choose in a particular case, you need to understand the variety of its types. There are many of them, and they differ in composition, purpose, scope, readiness for use, price and other parameters, on which the outcome of the choice depends.

Structure

The composition of the putty mixture is the main parameter on which the quality of the finish depends. If you buy a good, expensive, high-quality mixture, but do not think about whether it is suitable for application to your surface, money and labor will be wasted.

In this article we will not talk about all the existing types of putty, we will focus only on those that are used to align walls and ceilings.

So, in terms of their composition, they are divided into:

• Cement Their main advantage is high moisture resistance, and the main disadvantage is shrinkage during the drying process with the possible formation of cracks. The low price of such putty attracts buyers with a limited budget. But when decorating facades, as well as rooms with high humidity can not do without it.

Cement putty for finishing

• Gypsum. They are not able to withstand moisture like cement, so they can only be used in dry indoor rooms. This putty is non-shrinking, i.e. when dried, does not crack, preserves a beautiful smooth texture, which allows you to use it as a base for painting or wallpaper decoration.

Gypsum mixes perfectly on both plastered and plasterboard surfaces.

Note. It is quite difficult for beginners to work with this material because of its quick setting. Therefore, the mixture must be prepared exactly as much as you have time to put on the walls for the time period indicated on the package.

• Polymer. The most expensive of these, but at the same time the most durable and high quality, they are easiest to apply with your own hands. By the type of binder, synthetic putty can be latex or acrylic. The high cost is compensated by the long shelf life and solidification, as well as the ability to create the perfect surface when applying a very thin layer, which allows you to save material.

Polymer putties are most often delivered ready to use.

Appointment

To choose a putty suitable for your purposes, you need to decide on its purpose:

• Start (cm.Starting putty for walls: types, purpose, application) is intended for rough alignment of walls, bringing them to the level. It has a coarse-grained structure, can be applied with a sufficiently thick layer, dries for a rather long time.
• Finish line (cm.Finishing putty for finishing) has a smooth uniform texture with a minimum particle size. This is a very plastic putty for thin coat application. It is used for “smoothing” surfaces, their final preparation for finishing.
  The color of such mixtures is usually white, which makes it possible to stick even light transparent wallpapers or apply pastel paints to the prepared base.

The walls after finishing putty are perfectly flat and white.

Tip. To ensure better adhesion of the finish layer to the leveling one, use products of the same brand from the same manufacturer.

• Universal. The instruction for such formulations states that they can be used for different types of work: both for leveling the surface and for its final preparation.
• Decorative structural putty - This is a mixture that allows you to create a textured surface, which in itself is the final decorative coating that does not require additional decoration, except for painting. Although now on sale there is a colored putty and compositions that can be tinted before application.

A beautiful surface texture, as in the photo, is given by fillers in the form of mineral chips of different fractions

Application area

Everything is simple here: putty can be designed for outdoor or indoor use. In the first case, it should have moisture resistance, frost resistance, resistance to mechanical stress and other physical characteristics that allow the composition to normally "work" in the most difficult weather conditions.

Facade putty should have special properties

Less stringent requirements are imposed on mixtures for internal use, but they must also correspond to the purpose of the room and have good adhesion to the base material.

How to choose a putty

Even the meager information that was given in the first part of the article is enough to be able to choose the right material. The rating of putties by price, manufacturer's reputation and other parameters will give you less than this knowledge. Although, of course, they are worth paying attention to.

So, let's look at a few examples:

Conclusion

As you can see, there are many nuances when choosing a putty, all of them must be taken into account in order to be confident in your choice and the quality of the work done. This is not difficult at all, and even the above information may not be useful to you, since there is always information on the scope and method of application on the packaging with building mixtures.
