As you know, the preparation of plasterboard structures is included with many types of preparatory work, among which we can note the shtlock, stripping irregularities and roughness, and of course the primer of drywall before putty.
Why apply several layers of the sealing mixture? What does it give us? To begin with, with the help of data of manipulations, it is possible to greatly improve the strength of the entire design, make it more rigid. In addition, you will be much easier to apply putting on the plane, since the primer for drywall under putty largely improves the "chain" of the working surface.
Beautiful and durable designs - all thanks to the primer mixtures
Types of primer - disassemble everything in the shelves
Before answering the question - whether it is necessary to primer drywall before putty, let's consider all known types of mixtures for the progress of GCL. After all, it is precisely from their type and quality that the time is largely dependent on drying, the number of layers (necessary for application), etc. In general, it is necessary to primitive GLC before putty.
Treat GLCs very desirable!
In the modern construction market, you can see several mixtures options, but not all of them can be used for internal work:
- Universal acrylic . This type falls on any plane. The time required for drying is from 2 to 4 hours. This type of primer is the perfect option for use in the processing of plasterboard structures;
- Phenolic . These mixtures are used on metal and wooden surfaces. Such primer cannot be applied on top of a putty, but it will suit the first layer.
Note!
When buying this type of primer, you should pay attention to the label (there must be specified if it can be used indoors, or not).
- Alkyda . This mixture is designed exclusively for working with wood. On top of the putty, apply such a composition is strictly prohibited;
- Perchlorvinyl . This primer can be applied on any surface, but there is one thing - it applies only for outdoor work;
- Glyphthalian . The most powerful mixture of all now known. It is possible to work with it only in well-ventilated rooms. For residential rooms, it is not intended;
- Polyvinila acetate . This mixture applies only with polyvinyl acetate paints. Plus - quickly dries (for only forty minutes);
- Polystyrene The primer is the last on our list. This mixture is sufficient toxic, therefore it is recommended solely for external work.

Acrylic primer - the most optimal and affordable option
So, the putty and the primer of drywall, as we found out, is produced mainly by an acrylic mixture, which is applied both before and after putty. It is an acrylic mixture that is capable of providing all the necessary properties that the base acquires after processing, before starting finishing works.
Do you need a primer at all
Is it necessary to primer drywall before putty? Here the thing is that when working with any plasterboard design, for finishing works, a number of preparatory manipulations are necessary.
With the help of processing, you can significantly increase and improve the clutch of the surface of the drywall with paint, glue and putty. Also, you can reduce the timing of finishing works and even save a little on building materials, the price of which is constantly growing.
Applying putty on top of the primer
In essence, the primer penetrates into the working surface (in our case plasterboard) and strengthens its structure. In addition, primer mixtures contribute to uniform and more economical paint, glue, putty, etc.
Attention!
Among other things, special mixtures will help protect your design from the appearance of fungus and mold.
After applying each layer, a complete drying of the mixture should be waited for a mixture: it is recommended to primitive with a simple roller, as it can be achieved a homogeneous and smooth surface with it.

Printing - step-by-step instruction
So, after you installed the design of drywall, you will need to properly prepare for further finishing, that is, in other words, to primar the surface with your own hands.
Spatula also have a different "caliber"
In order to progress the surface correctly, it is necessary to prepare the following materials and tools:
- The primer (quantity depends on the size of the HCL of the constructions, it should be remembered that the consumption of material is entirely dependent on the manufacturer);
- Roller and brush for applying material onto a working surface;
- Capacity (in our case, it is customary to use special corrugated containers, with a roller width and a small deepening).

The primer can be applied both roller and brush
So, when everything is ready, you can proceed directly to work:
- Initially, as mentioned earlier, it is necessary to choose a primer. Remember that it must be suitable for processing drywall and did not have toxic elements in its composition (suitable for interior decoration). It is better to choose an acrylic, which you should breed in water before use;
- In general, the choice of choice is largely dependent on the type of finishing material, which will later be used. The easiest and most popular option is painting or sticking wallpaper. In this case, experts recommend priming drywall such a mixture that does not deeply penetrate the structure of the working surface. But if the wallpaper is severe, then a mixture of deep penetration is used - it will largely improve the hitch of the wallpaper glue with GLC (wallpapers will be kept much longer and stronger);
- Well, we decided with the solution, we can now proceed directly to priming. To begin with, you should dilute the mixture with water and pour it into the cooked container. Then, we take a roller and dip in the solution - the surface must be covered carefully, since the layer should turn out to be smooth. Each layer should be applied to the entire plasterboard surface - where it is not possible to apply a brush with a roller, you should use a brush. Further, it remains only to wait when the primer layer is driving (it depends on the type of primer and from the depth of its penetration into the structure itself);
When aligning the surface, take care of yourself and your health
- So, after everything dry, the joints and seams must be punctured by the serpanka. Then we take the putty and process the GLC surface. Despite the fact that the primer and plasterboard putty are quite simple events, approach these works should be very careful, because it is precisely the strength and durability of your finishing. After putty and complete drying, the surface is processed by sandpaper and removes all dust.

It remains only to apply the finishing layer of primer
As the last stage, the finish priming can be noted, which is applied on top of the putty of plasterboard. After drying, you can safely begin to decorative trim of plasterboard design (see photo).
Output
Many mistakenly believe that for finishing Glk, it is enough just to put a putty on them - but this is a delusion! So that the same putty firmly kept on the designs and eventually did not crumble and fall off, it is necessary to prepare a solid foundation with excellent tank indicators.
