Currently, it is difficult to imagine repairs without the use of modern materials and tools. They help builders create better, more durable coatings..
One of these tools is a primer. This agent helps materials adhere and evens out surfaces..
It is important to know how long it will take for the primer to dry. This is the necessary information for workers and foremen to know when to start a new stage of repair work. This indicator is extremely important in the process of overhaul and finishing work..
It is a unique agent that helps to improve adhesion. The main advantage of the primer is its binding capacity.. Thanks to this characteristic, the consumption of paint, adhesive and other materials is significantly reduced.. A quality primer has good antibacterial and antifungal properties. Thanks to such characteristics, you can safely engage in wallpapering and not be afraid of the future appearance of fungus and mold..
A number of people consider the use of this tool before painting or pasting walls is meaningless. Most often this applies to novice craftsmen or people who want to independently carry out repairs in their home. Only with time do they begin to understand how deeply they were mistaken. After all, the preliminary priming of the walls helps to significantly save money by reducing the consumption of finishing materials..
After applying the primer to the wall, wait a while before proceeding with the repair work.. The manufacturers usually indicate the waiting time on the packages with the solution.. But this criterion may change due to the type of foundation and other aspects. If there is a dry or porous surface, it is possible to start further work in a very short time..
Before buying this product, you should decide for which surfaces it will be used. Do not forget about the attached instructions for the solution. The higher the penetrating power of the primer, the better it is..
Currently, there are several types of primers on the construction markets and in stores..
Let’s consider the most popular ones:
- Acrylic based primer is versatile. It can be used on almost all surfaces. After applying this product, any surface becomes smoother and less moisture absorbing.
- For woodwork, you should choose an alkyd solution.. It is also great for metalworking.
- Glyphthalic it is used as a basis for gluing wallpaper and other materials. It can be applied before plastering and plastering.
- Aluminum mortar only suitable for working on wooden surfaces. This primer helps protect against moisture, and also prevents the appearance of mold and mildew..
- Polyvinyl acetate products used as a base for painting. They should be used for special paints, concrete and wood substrates..
- Silicate primer should be applied on brick walls or under decorative plaster. This agent penetrates deeply into all cracks and fills them well..
- Epoxy primer performs well on concrete surfaces.
The primer dries in different ways. It depends on the substances included in its composition and the air temperature in the room..
When to prime?
The primer mixture can rightfully be called the most versatile repair tool. It helps to more firmly bond building materials together and prevents the formation of corrosion..
If in the process of work the walls were plastered, then they can be primed only after a month. Stir the mixture thoroughly before painting the walls. Usually it is applied in one layer, but in some cases it is required to apply several. The second layer is applied after the first one is completely dry..
Primers are applied to plaster or paint. In such a situation, the primer acts as a connecting link between the particles of paint or plaster, this helps to make the wall or ceiling smoother and saves paint or glue by reducing the absorbent properties of the surface..
When working with putty, it is also necessary to prime the walls. If it will be applied in several layers, then before each new layer it is necessary to cover the surface with a primer mixture..
Regardless of what the wall is made of, there will be cracks and various irregularities in it. The primer mix helps to smooth this out. Due to this, the next layer of finishing material lays down more evenly..
Primer improves paint adhesion to any surface. This protects the paint from cracking. The primer mixture helps to save putty. When dry, it forms a special film that prevents the appearance of stains and fungus..
It is much easier and smoother to apply a layer of putty to the primer. The mixture contains various elements that prevent the formation of mold and mildew.
The primer is applied to dry surfaces, previously well degreased.. If you do not follow these rules, then in the end you can get unevenly applied paint, cracks or peeling of putty and wallpaper..
Before proceeding with wallpapering, the walls need to be well prepared..
The priming mixture is diluted in a large container according to the attached instructions.. If lumps appear, mix them thoroughly.. A drill with a special attachment will help with this..
Then the resulting solution must be applied to the wall.. Experienced craftsmen use a roller. This helps to minimize your time costs..
After the first layer is applied, you need to wait a certain time. The amount will depend on the type of primer. Then the second layer is applied, and after it is completely dry, you can proceed to the finishing work. This will help reduce the amount of absorbent material in the drywall..
What affects the drying time?
The drying process is influenced by several criteria:
- Climatic conditions in the room. If the room is too hot or cold, the primer will take a very long time to dry..
- The thinner the primer layer, the faster it will dry..
- The primer contains special compounds that tend to quickly evaporate from the surface..
- Drying time also depends on the structure of the surface to which it will be applied. The deeper the mixture penetrates inside, the longer it will dry..
Before you start gluing the wallpaper, you need to wait until the primer is completely dry..
As a rule, manufacturers indicate information about the basic composition and the approximate time required for the solution to dry. Also, the time depends on the type of primer material.. Acrylic-based products dry within 5 hours.
Alkyd mixtures dry for a very long time. It will take 20 hours or more to wait for this. An important criterion will be the air temperature in the room.. Glyphthal primer dries longest. This product can take over 24 hours to dry. A the fastest in this regard are water-based products. After applying them, you can start gluing the wallpaper in 20 minutes..
When the product is applied to the wall, it is important to follow a few basic rules:
- maintain the same temperature in the room;
- avoid drafts, as they can cause uneven coverage;
- artificial drying should not be used to speed up the drying process of the primer.
After the surface is ready, you must immediately start gluing the wallpaper. When working with putty, a slightly different work technology is used. It is necessary to start the putty immediately after applying a layer of primer..
The deep penetration solution has several features. If the wall is porous, you may need two coats of primer.. The ideal temperature for working with such a solution should not exceed 25 degrees Celsius..
Using paint on floors, walls and ceilings is the fastest way to change the interior of an apartment or house. The paint can also be used in the bathroom, where the humidity is constantly high..
If the old paint cannot be removed, then a thin layer of primer must be applied over it. There is a special mixture for this case. After applying it, the surfaces can be painted after 2 hours..
A certain type of primer should be used on a concrete wall. Typically, an acrylic-based mixture behaves best in this case. For the facade, it is worth choosing film-forming mixtures.
Experienced craftsmen and builders recommend that you be very careful when choosing a primer. The choice of a specific product and a specific manufacturer will depend on the characteristics of the surfaces on which the primer will subsequently be applied..
The smooth surface of a concrete wall needs to be mixed with abrasive particles. They will make the surface rougher, which will facilitate better application of subsequent finishing materials..
Metal surfaces must be coated with a special mixture with anti-corrosion properties. This will protect the metal from rust..
There are special water-based primers for wood surfaces.. They will preserve the wood as long as possible and protect it from rotting and increased moisture absorption. The primer mixture should contain substances that prevent the appearance of bark beetles and other pests. If new wood is treated with shellac, it will not release resin. This will help to avoid differences in shades in the future..
For rooms with a high degree of humidity, it is worth using a primer with an antibacterial effect. This information is usually written by manufacturers on the packaging of the material..
To work with drywall, you should use a deep penetration primer. This will help reduce the amount of absorbent material in the wall covering..
It is necessary to apply a putty before the primer mixture for better adhesion of all materials. But the primer applied over the putty will contribute to a long service life.. It is worth paying attention and buying formulations from one manufacturer. This will allow all substances and components to reveal all their properties to a greater extent and perform their functions in the best quality..
After applying the mixture, temperature drops in the first 3 days should be avoided., after use. Otherwise, the entire coating may crack..
Some experts apply the primer mixture with a spray bottle. This will help novice craftsmen achieve a more even application on the surface..
Experienced builders recommend making a primer mix on their own in order to save the budget for some premises. It is important to calculate the required amount of building materials.
The old layer of plaster can sometimes not be removed. But before gluing the wallpaper, you need to walk on it with a mixture of deep penetration..
Some surfaces absorb a lot of moisture and are porous. To determine the required amount of funds for them, it is worth doing a little check. A piece of foam rubber is moistened in water and applied to the desired surface. In places where the liquid has absorbed faster, more primer will be needed..
The primer should only be applied to the surface from which mold and mildew has been thoroughly removed..
Walls must be primed before applying the topcoat.. In this, the opinions of all experienced craftsmen are unanimous. Thanks to this technology, you get a durable coating that will last for many years..
