How long does oil paint dry on different surfaces
Different types of paints are used to coat wooden or metal objects. The duration of the working period depends on the drying time of the oil paint. In the beginning, the main purpose of pigments was to use them in the creation of art paints. Modern compositions are complemented by special elements responsible for strong adhesion.
What determines the drying time of the paint
The length of the drying period depends on the characteristics of the elements that make up the paint.
| Essentials | Additional elements |
| butter | additives that can increase the durability of the finish created |
| wax solution | thinners |
| natural resins |
Oil, wax or resin are the main elements that determine the interaction of the accompanying components. Drying time, adhesion properties and durability of the finish depend on the quality and characteristics of the base.
In addition, many factors affect the length of the drying period:
- density and thickness of the paint layer;
- thinner properties;
- retained air humidity in the room;
- the temperature at which the paint dries;
- lighting availability.
Drying can be accelerated by several methods:
- the addition of desiccants, that is, substances that accelerate polymerization;
- the use of ultraviolet light for acceleration;
- to ensure a tight bond, the surface must be properly treated.
Information! The adhesion index increases when the surface is pretreated with primers.
Drying times of paints in various cases
When working with paint, you need to understand how long it will take to dry the composition in order to plan the course of work. Oil or resin paint has special qualities. The elements of the basic composition offer adhesion of different resistances and qualities to a surface such as wood, metal or plastic.
Oil painting
The painting, done on canvas, is the fruit of the work and talent of the artist. Work on a work of art is associated with the characteristics of the process and the quality characteristics of the material used.
The process of drying oil on canvas consists of several steps:
- Top layer dries, but a liquid consistency remains inside the smear. This stage lasts from a few days to 1.5 weeks. It depends on the density of the applied layer.
- The paint dries completely within all strokes made, providing strong adhesion. This stage takes from 1.5 weeks to several months.
Information! When creating an art picture, different types of paints are often used. Oil is used to paint the bottom and the top layers are finished with quick drying products.
Floor painting
Oil-based floor paint was widely used decades ago.There are now more practical formulations, but oil paint is still used to create a finishing coat on the floor.
The peculiarity of oil painting is the creation of a top film, which ensures the saturation of the pigment. The layer under the film remains soft for some time. Polymerization begins after the elements of the composition begin to interact with each other and provide adhesion.
It takes 26 to 48 hours for the soil to dry. At the same time, manufacturers indicate on the packaging of floor paint that after staining it is necessary to create optimal conditions for drying.
Reference! Additional factors help to shorten the drying time of the floor during painting. These include an artificial increase in the air temperature in the room to be repaired and a simultaneous decrease in the humidity indicator.
Aerosol
A feature of aerosol application is the creation of an even layer. The coating is applied from a distance of 15-25 centimeters, keeping the ball at a certain angle. This application technique avoids smudging and creates a thin layer. Thanks to the use of aerosol, the drying time of the coating is reduced to 12 hours.
Attention! If the layer is applied from an aerosol at a distance of less than 10 centimeters in violation of the position of the corner, then it is impossible to predict the duration of the drying period. The resulting coating will not be uniform and sagging will prolong the cure.
On walls or wallpaper
Wallpapering the walls for painting allows you to make repairs without dismantling and choosing new materials.To change the interior design, it is enough to change the color scheme and update the topcoat. Paint on walls or paintable wallpaper is usually applied in two layers. The top layer is designed to protect the finish from external influences. The drying time of the topcoat varies from 3 to 24 hours. It depends on the type of paint used and the thickness of the layer applied.
On parquet
Wooden surfaces absorb liquid compounds well. The use of paint on a different base to coat the prepared wood supposes the creation of a strong adhesion:
- the first coat penetrates the wood, creating a thin layer;
- the second layer is the main layer when fixing the color scheme;
- the third layer provides uniformity and saturation of the coating.
Floor paint dries on average in 24 hours.
On metal
Metallic surfaces have special properties. For coating, specially designed compositions are often used that prevent corrosion of metals and have protective qualities.
Acrylic
Acrylic compounds dry to metal in 30 minutes to 2.5 hours. The duration depends on the thickness of the coating made.
Alkyd aerosols
Each coat of alkyd aerosol dries in 1 hour. It takes no more than 24 hours for the coating to harden completely.
Nitrocellulose glazes
Metal nitro paint is often used during repair work. The drying time is 30 minutes.
Varnish in aerosol cans
Varnishing is the final step in a variety of repair or design processes for interior items or appliances. The lacquer layer must be dried for 24 hours.
How quickly different types of paint dry
When planning a repair, it is customary to choose the paint in advance. The time spent on work depends on the length of the drying period.
Oil
Oily bases are classified as long drying bases. The composition takes 2-3 days to harden. To obtain rapid polymerization of the oily layer, it is recommended to follow the rules:
- layers are applied with light movements, without creating uneven strokes;
- when using an oil composition, it is recommended to be limited to the creation of 2-3 layers of coating;
- in order to speed up drying, the air temperature is increased in the room, the flow of cold by the wind is excluded.
Enamels and nitro paints
Enamels and nitroenamels are formulations based on nitrocellulose components. It will take 10-30 minutes to create a solid bond with the nitro enamel. The composition dries well at an air temperature of +20 to +24 degrees.
Reference! When painting with several layers of nitro enamel, it is necessary to wait until the previous layer is completely dry. This technique is called the "dry method".
Aqueous emulsions
Water-based emulsions have many advantages. One of the advantages is the speed of drying. For the initial polymerization of the coating, 2-3 hours are sufficient. If a dense layer is created using water-based paint, then it will take 12 hours to fully harden.
Automotive Acrylic
The acrylic compound applied on the machine consists of artificially released resins. The density and adhesion of the acrylic coating are sought when repairing and painting equipment.Acrylates are not susceptible to fading from the sun, which is highly appreciated by owners of cars or special equipment.
Acrylics dry completely in 1 day, but applied coating cures in 20 minutes from start of application. Some modern paints take 10 minutes to harden.
Latex
Latex paints are a type of aqueous dispersion formulations with the addition of resins, acrylics and synthetic polymers. Latex compounds are designed for painting interior and exterior spaces. The latex is suitable for repairing fabrics, canvases and other types of coatings. The length of the drying period depends on the thickness of the applied layer, which hardens in 5-10 minutes.
Rubber
Rubber paint is often used for interior applications. At an air temperature of +20-+24 degrees, the rubber base begins to harden in 1 hour. It takes 2-3 hours to create a strong bond.
Silicone
The silicone composition is made on the basis of organosilicon resins. Special thinners are added to the resins, which structure the composition. At first, silicone was used only to create paintings, as well as in the process of creative painting of fabric surfaces. Modern silicones are suitable for renovation and interior design.
Silicones are applied by roller, spray gun or brush. This composition is easy to use, has high durability, is not subject to mechanical stress and provides a uniform and durable coating. Drying times vary from 2 hours to 24 hours. It depends on the thickness of the created layer.
