How long does the primer dry How long does the primer dry on the walls - drying time

At the moment, it is difficult to imagine renovation work without the use of modern tools and materials. They will help builders make more durable and better coatings. One of them is the primer mix. This tool helps the adhesion of materials, and also levels surfaces. Let's take a look at how long the primer dries.

It is very important to know how long it takes for the primer to dry out. This is the necessary information for foremen and workers to know when it is necessary to start a new stage of repair work.

This indicator is very important for major repairs and facing works. The products are unique in their properties, as they help to improve adhesion.

Features of the composition

The main advantage of the primer is its binding ability.

Due to this parameter, the consumption of paints and varnishes, adhesive composition and other materials is greatly reduced. quality primer material has excellent antifungal and antibacterial qualities. Due to these characteristics, you can calmly deal with wallpapering and not be afraid of the formation of mold and fungal colonies in the future.

Many people consider the use of such a tool before painting or pasting walls is pointless. Most often this will concern people or novice craftsmen who wish to carry out repair work in housing with their own hands.

Only after a while will they begin to understand how deeply everyone is mistaken. The fact is that preliminary priming of the walls will help to save a lot on other finishing materials. After applying the primer, it is necessary to wait a certain time before starting repair work. The manufacturers usually prescribe the waiting time on the package with the composition. But this criterion may change due to the variety of the basis and other aspects.

If the surface is porous or dry, then further work can be started after a short time interval.

Please note that before purchasing such a product, you should decide on which surfaces it will be applied. You should not forget about the attached instructions for the solution, and the higher the penetrating power of the composition, the better it is.



At the moment, there are several varieties of priming compounds in shops and construction markets. We propose to consider the most popular of them:

  1. How long does the primer dry The acrylic-based primer is universal - it can apply to the treatment of all types of surfaces, and after applying such a composition, all surfaces become smoother, and also absorb less moisture.

  2. Alkyd mortars should be chosen for woodworking. They are also great for machining metal parts.
  3. Glyphtal is used as a base for gluing wallpaper and other types of materials. It can be applied before plaster or filler.
  4. The aluminum compound is only suitable for working on wooden surfaces, and this primer helps protect against moisture, and still prevents mold and mildew from appearing.

  5. Polyvinyl acetate compounds are used as a base for painting, and such agents should be used for special paints and varnishes, as well as bases made of wood or concrete.
  6. The silicate primer should be used on brick walls or under decorative plaster. Such a tool penetrates deeply into each of the cracks and fills them perfectly.
  7. Epoxy is excellent for concrete surfaces.

The primer dries in different ways, and it depends on the substances it contains and the temperature of the air inside the room.

When priming is required

The primer mix can rightfully be called a universal repair agent. It helps to better bond building materials together and prevents corrosion. If the walls were plastered during the working process, then they can be primed only a month later. Stir everything thoroughly before painting the walls. Usually the mixture is applied in 1 layer, but in certain cases it is required to apply several.

The second layer after the first is completely dry. Primers are applied to paint or plaster, and in this situation the primer will play the role of a link between the particles of plaster and paint, which will help to make the ceiling or walls smoother, and it also makes it possible to save adhesive or paint by reducing the absorbent qualities of the surface.

When working with putty, the walls should also be primed. If it will be applied in several layers, then before each new layer it is required to cover the surface with a primer mixture. Regardless of what the wall is made of, there will be various irregularities and a crack in it.

The primer mix helps to smooth this, and due to this, the new layer of finishing material lays down much more evenly. How long does a deep penetration primer dry? Not for long. The composition helps to improve the adhesion of paint to any surface, and this protects the paint from cracking. The primer mix helps to save putty. When dry, it forms a special film that prevents the formation of fungus and stains.

It will be much easier and smoother to apply a layer of putty on the primer, and different elements are included in the mixture. The primer is applied to dry surfaces that will be well degreased in advance. If you do not follow these rules, you will end up with unevenly applied paint, peeling wallpaper / putty, or cracks.

Before you start gluing the wallpaper, you need to prepare the walls as best as possible. The primer mixture must be diluted in a large container according to the attached instructions.

If lumps form, stir the mixture thoroughly. A drill with a special attachment will help with this. After the resulting solution is required to be applied to the surface of the walls. Experienced people use a roller, and this helps to minimize their time costs. After the first layer is applied, you need to wait a certain time.

Its number will depend on the type of primer composition. After the second layer is applied, and when it is completely dry, you can start finishing work. This helps to reduce the amount of absorbent material in the drywall sheet.

What affects the drying time

Many criteria will influence the drying time:

  • How long does the primer dry Climatic features in the room - if the room is very cold or hot, then the primer will dry out for a very long time.
  • The thinner the primer layer, the sooner it will dry.

  • There are special compounds in the primer that have the property of quickly volatilizing from the surface.
  • The drying time will depend on the structure of the surface on which it will be. The deeper the mixture gets inside, the longer it will dry out.

Wait until the primer is completely dry before you start gluing the wallpaper. How long does the primer dry before wallpapering? Usually, manufacturing companies indicate information about the main composition and the approximate time it takes to dry.

It will also depend on the type of primer, and the acrylic-based product dries out within 5 hours. Alkyd compounds dry out for an extremely long time, and it will take 20 or more hours to wait. The most important criterion will be the air temperature inside the room, but the glyphthal composition dries out the longest. It will take more than a day to dry the product. And the compositions based on water dry the fastest, since after applying them, you can start gluing the wallpaper after 1/3 hour.

When the composition is on the wall, several important rules will be required:

  1. Maintaining the room at the same temperature.
  2. Avoid drafts as they can cause uneven coverage.
  3. Do not use artificial drying to speed up the priming drying process.

After the surface is ready, you need to immediately start pasting the wallpaper. When working with putty, a slightly different working technology is used.

It is required to start the putty immediately after applying the primer coat. Deep penetration mortar has several properties. So, for example, if the walls are porous, then 2 primers may be required. The ideal temperature for working with such a composition should not be more than +25 degrees. Applying paint to walls, ceilings or floors is the quickest and easiest method to change the interior of a house / apartment.

The paint and varnish composition can be applied in the bathroom, where the humidity level is always high.

If the old paint coat cannot be removed, then a thin primer coat must be applied over it. For this case, there is a special mixture, and after applying it, the surfaces can be painted after a couple of hours. A certain type of primer should be used on a concrete wall, and as a rule, an acrylic base is ideal in this case. For the facade, choose film-forming mixtures.

Tips and tricks

Experienced builders and craftsmen advise to be very careful when choosing a primer composition. The choice of a specific product and a specific manufacturer will depend on the parameters of the surfaces on which the primer will be applied in the future. A smooth concrete wall surface needs a mixture containing abrasive particles. They will make the surface rough, which makes it easier to apply further finishing materials. Metal surfaces must be coated with a special mixture with anti-corrosion properties.

This protects the metal from rusting.

For wood surfaces there are special primers based on. They preserve the wood as long as possible and protect it from increased moisture absorption and decay. The primer mixture should contain substances that prevent the formation of bark beetles and other pests. If a new tree is treated with shellac, then it will not release resin.

In the future, this helps to avoid differences in shades. For rooms with a high degree of humidity, a primer with an antibacterial effect should be used. Such information is usually written on the packaging of the material, next to the data on how long the primer dries.

Deep penetration means should be used to work with GCR. This helps to reduce the amount of absorbent material in the wall covering.

Apply a putty before the primer mixture is required for perfect adhesion of all materials. But the primer on top of the putty will contribute to a long service life. You should pay attention and buy the composition from the same manufacturer. This makes it possible for all components and substances to more fully reveal their qualities and perform their functions efficiently. After applying the mixture, avoid temperature changes for the first 72 hours after application.

Otherwise, the coating may crack. Sometimes specialists apply the mixture by means of a spray gun, and this helps novice craftsmen to achieve uniformity in application to the surface.

Experienced craftsmen advise to do it yourself to save the budget in some rooms. Here you need to calculate the required number of building materials. The old plaster layer can sometimes not be removed, but before gluing the wallpaper, it is required to walk on it with a mixture with deep penetration.

Certain surfaces absorb a lot of moisture and also have a porous structure.To determine the required amount of funds for them, you should perform a small check. The foam piece is moistened in water and applied to the required surface. In places where liquid has quickly absorbed, more primer mix will be required. The primer should only be applied to surfaces from which only mold and mildew has been removed.

It is important to process the walls before applying the finishing coat, and in this the opinions of all masters are unanimous. Due to this, a high-strength coating is obtained, which lasts for years.
