Is this process mandatory?
Is the primer of gypsum board before the putty the mandatory procedure? Perhaps not, if the surface is clean and free of dust, because then the putty and so will have good adhesion. However, when installing plasterboard sheets, its horizontal seams are cut with a knife at an angle of 45 degrees for better contact of the material with the putty. Therefore, these seams must be primed.
Native stitches and surface, provided that they are clean, can be left without additional treatment. These conclusions are based on the recommendations of specialists. If you take as a basis the instruction for the finishing works, then it is clearly stated that before the painting the putty must be primed. The consumption of material for drywall is small, but the benefits of this are great.
The primer absorbs very quickly and makes the material much stronger. In addition, you can safely use any kind of putty, since the adhesion will be very good. Therefore, whether to spend money on a primer, or not, it's up to you. If you decide to process drywall before the putty, then the question arises, which primer is best to choose?
Note! Since the primer is an inexpensive material, you will not be able to save on it.
Selection of
materials When buying a primer, it is necessary to pay attention to the following:
- of the Manufacturer of the product;
- Cost of the material;
- Shelf life.
To primed plasterboard, use only materials for interior work, and in no case for facade, as they contain harmful substances. This does not apply to all mixtures for external use, there are also such that they can be used both inside and outside the premises, but they are quite expensive. If you choose products cheap and from an unknown manufacturer, then you can not count on high quality.
Having decided on the question of whether it is necessary to primed the walls before the putty in favor of the need for this operation, if possible, do not save on the primer and get the products from the proven manufacturers. This will cost you more, but cheap products, in addition to being much weaker in quality, are also produced with the use of substances harmful to health.
Note! When buying any mixture, check its quality certificate, composition and scope of its application.
Carrying out work in accordance with
regulations Now consider the primer, according to the instructions for the finishing work. It turns out that the question of whether it is necessary to be primed before puttying does not arise at all, since this is considered an obligatory procedure. It is necessary to make a primer in at least one layer, as it creates a moisture-proof film that does not give much absorption to the paint. The layer of the applied mixture after drying should be a minimum of 0.03 millimeters. Working with the mixture, it is necessary to read the instructions and recommendations of the manufacturer.
Some manufacturers specially tint the primer with a pink or yellow color, so that it is convenient to control the uniformity of the application of the layers. It is necessary to pay attention to the fact that not all paint manufacturers indicate the recommended primer coat, therefore, when deciding whether to wall the walls before puttying, it will be necessary to consult with the masters about the correct performance of the work.
Important! For the duration of work on the priming of gypsum board, it is necessary to ensure good ventilation in the room.
