How to choose the right primer for different surfaces

Application primer mixtures for repair quite reasonably, as any finishing material must be kept under very tight andreliably.For this purpose, a primer, and what to choose for the walls and the flow will help you in this article.

Types modern primer

Modern manufacturers offer a huge amount of primer mixtures.Select the appropriate types of primers for concrete, plaster, putty is not always easy.For this purpose it is necessary, first of all, known variety.You can not use one type of primer and paint, and wallpaper.

Depending on the application, the types of primers for walls and ceiling are divided into the following groups:

1. Alkyd: apply only for wooden surfaces and constructions of metal;
2. Acrylic: have universal properties, respectively, suitable for different surfaces.Primers of this group to penetrate deep into the 1 cm this property allows you to use acrylic primer for deep impregnation of a base.;
3. Aluminium: only used for wood.With their help, the wood is completely isolated from moisture, thus minimizing the occurrence of such unpleasant phenomena as mold or fungus;
4. Polyvinylacetate: apply only when using the paint specially formulated for concrete primers, wood, metal, plaster;
5. Silicate: this kind of processed decorative plaster and silicone brick;
6. Shellac: helps prevent the allocation of wood resin, respectively, is used as a kind of primer for the ceiling and walls;Epoxy
7. : useful as deep Surface treatment of metal and concrete.Their main advantage - corrosion protection and sufficient strong adhesion.

Based on the above classification, before how to choose a primer for walls, necessary to determine the material surface to be primer and then a mixture of purchase.

Tip: selecting a primer, look at the manufacturer's price and specifications.The deeper the level of penetration of soil into the ground, the better it is for all purposes.

All of acrylic primer

most common primer which you can choose in different cases - is acrylic.It is versatile and makes the final finish quality and durable.In turn, the types of acrylic primers also have their own classification and depending on the application and purpose priming divided into:

1. Universal: used on all surfaces and in all conditions.This primer is equally well suited for both interior and exterior painting and decorating.If you do not know how to choose a wallpaper primer that used for subsequent finishing with tiles or a painting, take universal.A solution of this mixture is a little unclear, almost colorless.A special place in a wide range of universal acrylic primer has a very popular today priming paint.Its use helps to simultaneously solve several problems: reliably seal the surface, get rid of the possible appearance of mold and fungal bacteria, apply a coat of paint.Composition white surface and is not only primed, but also colored.

Tip: buy a ground-paint can in any store.It is possible to achieve the desired color by adding a dye primer.For example, after priming the wall is planned to paint in blue.Add the blue dye and a first layer of paint ready.

2. Types of primers deep penetration have all the characteristic qualities of acrylic primer.However, this type of primer is much deeper into the work surface, flatten it, thereby stronger interlocking base.

absorption length is 1 cm. In the matter of what to choose primer deep penetration or conventional universal, primacy should be given to the first group.smoothing effect makes the surface of a perfectly flat, since there is bonding of fine particles of sand and dust.This is a great option as primed the wall under the wallpaper, plaster and even tiles.

3. Adhesion: silica in the composition has an impurity which makes the surface is slightly rough, which in turn, adheres much more durable finish heavy materials.This is a good way out, when you do not know what primed the wall before plastering.

methods priming: when and how to do it

primer application method does not fundamentally differ from the methods of applying other finishing materials.The surface is cleaned, trimmed, polished and degreased, if necessary.To a question about how much time you need to prime the walls or ceiling, it takes an individual approach, but at least two times.

For application used tools such as:

1. Roller;
2. Brush;
3. Pulvezator

In each case, the tool is adjusted individually.For example, apply the primer to the brick surface of a brush better, but on a flat ceiling or drywall - a roller.Pulvizator rarely used, since after it is not easy to wash the room.

Primer ceiling

Since repair of the ceiling in the home, it is necessary to study the information on how to properly prime the ceiling.After all, despite the apparent ease of use, there are certain rules:

1. determine what primed the ceiling, try to do it evenly.Improper distribution after painting will be immediately visible.The place where the primer is applied thicker will be darker than the entire surface;
2. Before priming before painting the ceiling, select the direction of the application of the bonding material.When a primer layer is made flat along the perpendicular wall with a window.When a two-layer application of the first layer is parallel to the wall with a window, and the second - perpendicular to the same.

Primer walls

Blot wall is necessary in any case.Another question is better primed walls, but more on that later.Before priming the surface requires mandatory training: it is necessary to remove the old paint, clean up irregularities putty slot, remove dust and dirt.

The paper should follow the technology, and not do anything in haste.The first coat of primer should be sure to dry and then you can apply a second layer.Distribute evenly necessary.Particular attention should be to focus on the moment when you need to prime the walls under heavy wallpaper.In such cases, should not be used as a primer wallpaper paste (as advised many).

Of course, one could argue, why you need to prime the walls, if they will still be sealed?First of all, the wallpaper will be held firmly, will not bubble when glueing.Yes, and in the future on these walls will not appear any dirty trick in the form of mold or mildew.

Like what primed the walls for painting

Priming the walls necessarily, and the question of what primed the walls before painting, we can safely say - a universal primer.It possesses all the necessary properties and is suitable for different situations.

very often have to decide whether you need to be primed before painting?Some believe there is: a mixture of primer dries, leaves a band that after painting stand out clearly.A dust and dirt can be removed with a vacuum cleaner.Others, however, argue that this should be mandatory.Here it is necessary to decide on their own.Want a practical repair - soil, want to save money - not the ground.

Often the walls are made of gypsum board, as it is affordable and practical material.Usually, it is perfectly flat and, accordingly, many wondered whether primed drywall need?Yes, certainly, because the process of priming not only aligns the walls, but also serves as an excellent base adhesion factor to finish.

used in this case, again, the universal primer, doing the work in the following sequence:

1. soil for the first time;
2. shpaklyuyut;
3. soil again.

only after complete drying, proceed to the surface of the painting.

Tip: when working with primer in the room temperature should be in the range of 5-20 degrees of heat, humidity up to 75% and no drafts.

Like what primed the walls under plaster

plaster used on brick, concrete or aerated concrete surfaces.They tend to have high porosity and absorbency, and the question of whether primed before plastering, should be beyond doubt.Choose in these cases primer deep penetration.It not only links the ideal, but also has antiseptic properties.

Blot before plaster is necessary in several layers.Use better brush or roller.Each layer dries for about an hour, and at this time it is necessary to protect the walls from falling in the dust and dirt.Temperature readings of this type of primer are identical with the universal.The main thing - carefully read the instructions and follow it.

Exactly the same demands are made when there is a question whether we should be primed before the filler.All the same, even more, because a clean layer of putty will not hold any decorative material.

Thus, summarizing all the above, it is necessary to mention the most important: it is necessary to prime the surface, this should be done in accordance with the rules, choosing a primer to prime the ceiling or wall.
