  1. Acrylic primer can be used everywhere, except for metal surfaces. It is most popular among builders.
  2. Alkyd. Good for the untreated wood - it will smooth out all the irregularities.
  3. Shellac. Applied for processing knotty boards.
  4. Polystyrene. Although it lies well on wood and plaster, it contains harmful substances for breathing. Priming it walls in living quarters can not.
  5. Glyftalic, perchlorovinyl and some other primers are suitable for metals.
  6. If there is a possibility of developing mold or fungus, then it is better to use the mixture with antibacterial component.

  Required tools

  After you have purchased the necessary primer, you need to stock up on the tool. For work you need the following tools:

  1. Foam or fur roller with a pile of medium length. If the roller is already there, then you can simply purchase the necessary "fur coat" for it. Telescopic extension handle for roller.
  2. Brushes of different widths.
  3. A bucket or other container where you can build a primer.
  4. Respirator if toxic mixtures are used.
  5. Sprayer( optional).Its use will help reduce the likelihood of streaks when applying the solution, will help to distribute it evenly.

  Preparing surfaces for operation

  Before deciding how to apply a primer and determine where it is more convenient to start work, you need to prepare the surfaces for this process.

  • completely clean, plaster the surface;
  • if there were wallpaper, then completely remove them( if badly removed, you can wet, remove the wallpaper, and then let the wall dry out);
  • old paint or whitewash retract;
  • if the plaster cracked, these places should be knocked down and fresh layers applied.

  After drying the wall after soaking the wallpaper or applying the plaster, you can proceed to the next step.

  We proceed to priming

  This process is simple: after reading the instructions on how to properly primed the walls with this composition and how to properly plant, you can take up brushes and a roller.

  1. If there are toxic substances in the formulation, wear a respirator before use.
  2. Roller plunge into a container with a primer, soak well, squeeze out excess on the edge of the container.
  3. Wall processing can be started. The process of impregnating the composition will go much quicker, if the roller immediately put on a telescopic extension knob, after which you will not need a different stage. The walls can be immediately processed from floor to ceiling.
  4. It should be ensured that the primer is laid flat, not accumulating in one place, otherwise there will be a chance of divorce and staining.
  5. It is necessary to achieve uniform moistening of surfaces, because this depends on the adhesion of the decorative finish to the wall.
  6. After processing a part of the wall, it is necessary to lay the roller aside, arm with brushes. They need to process those places where the roller could not be obtained: joints of walls, places behind the radiator, areas near the floor, ceiling. Then wait a couple of hours to apply a second coat.

  Advice: Accelerate drying of walls, raising the temperature in the room or using additional thermal sources, is highly undesirable. The primer dries quickly.

  Features of the processing of plasterboard surfaces

  Many do not consider it necessary to primer drywall. Why should the walls covered with plasterboard be primed if its surface is smooth and even without it? This belief is not entirely true, because when replacing wallpaper, pasted on it without preliminary processing, until the end it will not be possible to remove old ones without damaging the base. This can cause the paper to peel off a new coating, the appearance of bubbles.
  
  When working with gypsum board, it is necessary to take into account some material features:

  • with alkyd primers can not use alkyd formulations: their chemical formula can disrupt the surface of gypsum board;
  • if the direction of work does not play a big role in the priming of conventional materials, then it is extremely important that the mixture is uniformly applied by the roller from top to bottom along the entire surface to be treated, after which it should be allowed to dry well and the application of the decorative layer can begin.

  Useful advices

  Some recommendations that will prompt how to primed walls quickly and efficiently:

  1. A porous, dry wall absorbs much more mortar than usual, so it is advisable to purchase a primer with a margin.
  2. To achieve a guaranteed result, primed, regardless of the surface condition, is better twice.
  3. If you impregnate small areas of the wall, for example, first from the middle of the wall to the ceiling, and then the lower section, the process will go faster, because you do not have to waste time changing the length of the telescopic handle.
  4. Carefully follow the uniform moistening of surfaces, because the slightest hackwork can disrupt the quality of repairs. This is a spoiled mood, additional costs for new unplanned repairs.
  5. If the wall is being primed for painting, then the mixture is better to take a white color - this will help to avoid unnecessary shades in the color scheme. On the white ground, the paint shade will spread more evenly.
  6. Primer should be carried out at a temperature of + 5. .. + 25 ° C, with a humidity of not more than 70%.The change in these parameters leads to a disruption in the quality of the impregnation and the rate at which it dries.

  Following a simple recommendation on how to primed walls, you can make high-quality repairs with your own hands.

  This can be done not only by professionals, but also by beginners with minimal painting skills.
