If when choosing the paint to discard personal preferences regarding the color scheme and cost, guided by more practical questions, we recommend paying attention to how much the paint dries.
Are there “universal” paints with the same surface drying time?
The answer is unequivocal-no. Universality is just a myth used by unscrupulous manufacturers solely for advertising purposes. At best, you buy paint with a one-time or very short-term effect. Therefore, it is not necessary to believe the manufacturer’s promises that the paint is equally ideal for repairing the paint surface of the car, for heating radiators and for decorating the kitchen or bedroom. Excellent results will only be achieved if the paint is used for a specific purpose. In other cases, you will get a mediocre result and simply throw money “to the wind”.
Often, the question of how much paint dries is crucial when choosing. This is objectively and directly related to its composition and the surrounding conditions in which drying should occur. Why is this important? The pace of paintwork has a direct impact on the overall speed of repairs. For example, it is not recommended to carry out any other finishing work while the paint is drying. Otherwise, dust and other construction debris will simply stick to the painted surface.
Common factors that have the same effect on the drying of any paint
Of course, the paint base has a direct effect on the drying rate. But, in addition, you should also take into account external factors that affect how quickly the mixture will harden:
- Surface porosity. The larger the capillary structure of the material to be painted and the amount of paint that gets inside – the longer the drying time. For example, the same paint on metal dries faster than on wood. All kinds of primers are used to close the pores and create a uniformly uniform surface.
- The temperature of the surrounding environment also has an impact on the rate of evaporation is included in the paint component. However, excessively high temperatures may not cause the polymerization to accelerate, but, on the contrary, make the composition more liquid and, consequently, slow down the drying rate. Manufacturers usually specify the temperature range allowed for paint application.
- Ambient humidity. Some paint compositions in humid air do not give off moisture, which increases the drying rate.
- Availability of ventilation. All paints dry faster with more active movement of air masses. However, drafts are contraindicated – a more competent solution is to use a forced supply and exhaust ventilation system, balanced in volume and speed.
- Another factor is the thickness of the paint layer applied to the surface. The thicker the coating, the longer the drying process.
Special attention should also be paid to the composition of the paint – more precisely, the type of solvent used in the base. There is a pattern here: the more harmful the base, the faster the polymerization process takes place. Nitroenamels traditionally dry faster than paints on oil base. Water dispersion paints also dry quickly.
How long does oil paint take to dry
Traditionally, oil-based paints are considered to be longest-drying. In recent years, manufacturers have refused to use natural drying oil for such compositions. Now in mass production of oil paints, alkyd or pentaphthalic bases are used. This reduced the drying time of oil paints to one day.
Complete solidification of one layer occurs only as a result of oxidation of the upper oil layer. Factors such as:
- air temperature;
- the presence of direct sunlight.
Oil paints dry longer with the addition of antiseptic compounds. The period of time sufficient for drying of such and similar paints is specified by the manufacturer on the Bank. In any case, the drying time is at least 12 hours.
How long does it take for enamels and nitro paints to dry
For most of these formulations, the second layer can be applied within 20-30 minutes after the first layer is applied. Approximately the same time it takes to dry the second layer. Manufacturers allow up to 12 hours for complete solidification with the possibility of using painted products.
Please note that the paint on the nitro base dries faster than enamel. It is due to the preferential areas of use of nitro paints and enamels. The former are mostly intended for painting metal and plastic surfaces (provided that the solvent in the paint base does not “eat” the plastic). Enamels can be used to cover any surface, including wood.
For enamel PF 115, for example, the drying time is directly related to the thickness of the layer applied during painting and the color of the paint. For example, it will take 48 hours for cherry and red enamel to dry. For everyone else, 24 hours is enough.
How long do water-based emulsions to dry
Water is considered the most environmentally friendly solvent for paints. Water-based emulsions, called water-dispersive paints, are used for painting almost any indoor surface.
For primary polymerization, 2-3 hours are sufficient. Complete drying – within a day. Some manufacturers produce water-dispersion paints with a reduced drying time of up to 12 hours. It is important that in conditions of high humidity, the drying time of water-based paints is practically unlimited.
Pay attention to the need for pre-preparation of the surface for applying water-based emulsions. Otherwise, the dye layer can be completely absorbed into the surface to be painted, leaving no traces of staining or leaving only uneven streaks.
Interestingly, water-based paint on the ceiling dries faster than on the walls. This is due to the fact that warm air flows always rise to the top, creating more favorable conditions for drying the paint. But for complete drying, it takes from 24 hours.
Does the form of release and method of application to the surface matter for drying the paint?
The correct answer is Yes. Paints in cans (aerosol) dry faster if they are applied to the surface in a thin layer.
Special attention should also be paid to surfaces with a high level of porosity, such as cement-sand plasters. Outwardly, it may seem that the paint on them has dried out, but in fact it is far from drying out. If the painting is done on lime plaster, the consequences may be even more sad because of the chemical reaction of lime with the paint base.
How long does acrylic car paint take to dry
For the basis of this type of paint, manufacturers use acrylic resins of synthetic origin. The advantages of their use are high-temperature stability (up to + 180 degrees C) and complete neutrality to alkaline and acidic environments, to alcohol and water. They practically do not burn out under the influence of direct sunlight.
They are ideal for covering metal car bodies, forming a particularly strong polymer film on the surface after drying. When applied to the body, a hardener is added to the base. The layer on the surface of the car body is cured within 20 minutes, provided that the paintwork is carried out in a specially equipped paint chamber with high air temperature inside. But it takes 24 hours to completely dry.
Special attention should be paid to the paint “Montana”. It takes only 15 minutes for it to dry on the surface of the car body.
How long does latex paint take to dry
Latex-water dispersion paints with the addition of polymers and acrylic. With various combinations of these components, a solid Foundation is obtained that can be used indoors and outdoors.
How long does floor paint take to dry
If you are going to paint the floor, quick-drying acrylic enamels are perfect. After just a few hours, you can start using the room, but for complete drying, it is recommended not to expose the floor surface to mechanical loads for at least 12 hours.
If you used oil paints the old-fashioned way, you need to look at the drying time on the paint cans. Let’s remind you again-different manufacturers specify different drying periods, it depends on the composition of the paint itself and some environmental factors.
When using PF 266 paint for the floor, it should only be applied to dry primed surfaces. The drying time of the first layer is at least a day, after which you can apply the second layer. Complete drying of each layer – 24 hours.
How long does wall paint take to dry
The drying time of paint for walls directly depends on the composition that you use for repairs. Specifically, each composition, taking into account the basis used for the production of coatings, we have described in the relevant sections of this article.
How long does silicone paint take to dry
The drying time of silicone paint in domestic conditions is from several hours to several days. This process is influenced by a number of environmental factors – primarily humidity and air temperature,
If you dry products in a special chamber, during the first hour the air temperature should be raised to 100 degrees, and during the second hour – to 200 degrees. For complete drying in such conditions, 2 hours is enough.
