How to accelerate the drying of paint: an overview of ways

No repair is complete without the use of paintwork. Various products are used both for outdoor and indoor use. If the composition dries for a very long time, the repair is delayed for a long period, so it is important to remember the properties of the substances used.

The problem of long drying paint

After applying the product, it takes a certain amount of time for it to completely dry. Some coloring compounds (oil) require a lot of time for this, while they smell sharply and are harmful to the human body. A mirror surface created with varnish can be damaged by a simple touch if the substance is not completely dry.

In order to avoid unpleasant consequences and not to redo the work performed, it is necessary to study the properties of products of various manufacturers and take care to ensure suitable conditions for drying.

Modern types of coloring compounds

There are many products on the market of paints and varnishes, the main characteristic of which is the drying time after application to the surface. Factors that affect drying time:

• humidity;
• air temperature;
• components of the tinting substance;
• properties of the material that is being dyed.

The most common types are alkyd, oil and quick-drying water-based. All types of coatings have different drying rates and have both advantages and disadvantages.

Water-based quick-drying

Such paints dry very quickly - in a few hours. They can be used for exterior and interior use. Compositions of this type paint any materials, including brick, concrete slabs, gypsum structures. They do not harm the environment and do not contain solvents of organic origin. After painting on the walls and other surfaces, a vapor-tight film does not form, so they will breathe.

Popular varieties:

• water emulsion and water dispersion;
• latex;
• wallpaper;
• acrylic.

Alkyd Compounds

Resins of natural origin are the basis of such products. Types:

• phenolic;
• urethane;
• pentaphthalic;
• glyphthalic.

They dry very quickly (up to 10 hours), however, drying water-based dyes takes less time. The coating is applied to various surfaces without difficulty and is suitable for work of any type: decorative, decoration, art.

Alkyd enamels may contain pungent solvents, so it’s best not to use them for interior decoration in an apartment or apartment building.

Oil

Paints of this type can be used for both facade and interior work. They are applied to metal, wood and other materials. A thick vapor-tight film forms on the plane, so the painted room is flammable and toxic harmful.

The oil tone dries for a very long time - up to several days.To accelerate drying, special catalysts are added to the coloring matter.

The use of catalysts

Such remedies are called desiccants. They are sold in all construction and hardware stores in the departments of goods for repair. These substances accelerate the polymerization process, that is, reduce the drying time of the wall or floor.

The drier is poured directly into the paint, enamel, varnish or other tinting substance. The instructions for use indicate the amount of catalyst to be added to 1 liter of dye. It is important not to exceed the indicated dosages, since the solution may curdle upon application.

Desiccant significantly speeds up the drying time. For example, an oil-based tone at room temperature can dry in a day.

Correct application as a guarantee of quick drying

When carrying out repair work, it is important to remember the factors that affect the drying time of the coloring compounds. If applied correctly, it dries quickly. Basic Rules:

• it is better to paint a wall or another plane in several stages - 2-3 thin layers will dry much faster than 1 thick layer;
• oil solutions are applied with a roller or brush, it is better to stop on the first option, since in this case the substance is more evenly distributed throughout the material;
• outdoor work should be carried out in warm, dry weather;
• the use of a special spray gun reduces drying time;
• It is advisable to preheat the wall, and the tone will dry out in a matter of hours.

What to do if the paint does not dry?

Sometimes it happens that the coating is applied correctly, the rules for working with the coloring matter are observed, but the wall or other surface does not dry. In this case, it is necessary to create suitable conditions that will help quick drying:

• to ensure constant air circulation in the room, it is desirable to create a strong draft: open the windows and open the doors;
• turn on the fan for artificial movement of air masses;
• remove all sources of humidity in the room;
• install additional heat sources in the room if the temperature is too low.

Temperature effect

The paint dries the moment the solvent completely evaporates from it. This process can occur much faster if you increase the temperature and lower the humidity level in the room. This can be easily achieved using the following devices:

• building hair dryer;
• infrared heater.

The use of such a technique implies compliance with certain rules:

1. Adequate distance from the painted surface to prevent cracking.
2. A gradual increase in temperature, otherwise the applied paint layer can be irreparably damaged.

Useful Tips

Recommendations of specialists that should be followed for quick drying of the tinting substance after application:

1. It is imperative to add a drier to the oil paint. It will speed up the drying process even when re-applying the composition.
2. During repairs in a residential area, it is better to replace the paint coatings with alkyd ones.
3. Before painting, you need to warm up the room, since the tone applied in a cold room will quickly thicken at low temperatures, will dry slowly and can hardly be distributed with a brush or roller.
4. The thinner the paint coat, the sooner it will dry. If after that the translucent areas on the material are visible, all painting operations are repeated every other day.
5. In order to avoid oxidation of enamel, it is necessary to ensure constant air circulation in the room, it is better to artificially create a draft.
6. The most favorable conditions are low humidity and high air temperature.
7. Modern building hair dryers have a separate paint drying function. When using the device, it is important to prevent sudden temperature changes and bring it much closer to the painted plane, since the applied layer may crack.
8. Small details, covered in tone, can be placed close to radiators or dried in the oven, choosing a special mode at a temperature of no more than 60 ° C.
9. An infrared heater will help to dry the wall, ceiling or floor due to the ability to penetrate under the dye layer and heat it from the inside. The paintwork, spreading out, is evenly distributed on the plane, therefore it dries in a matter of hours.

The problem of long drying of the paint remains relevant. Quick-drying water-based solutions may not always be at hand, so you should adhere to certain rules in order for the oil and other coatings to dry quickly. The use of special catalysts and devices such as a hair dryer or infrared heater will significantly reduce the drying time. However, even in their absence, you can achieve the desired result by creating suitable conditions in the room.
