If the acrylic paint is dry, how to dilute it and suitable solvents
There is often an excess of paint left after the job. It is kept in the closet for a long time and they remember when it is necessary to touch up a room or an area. However, to the surprise of the owners, it turns out that the paint dries and turns into a plastic-like substance. Buying a new bucket is inconvenient. Therefore, "masters" are trying to find what can be used to dilute acrylic paint if it has dried.
Features of composition
Acrylic enamels and paints are made on the basis of a polymer - polyacrylate. In addition to it and water, other substances are added to the composition that affect the properties of the paint. They increase strength, improve vapor permeability, moisture resistance and reduce the rate of abrasion. Due to this variety of physical properties, paint materials differ by category.
Among the main components are:
- latex;
- titanium oxide;
- lime;
- limestone;
- organic and inorganic solvents;
- drying accelerators.
These components are able to improve mixing in one direction or another. But they are not always compatible with each other.This means that using all possible parts of the composition at once will not lead to a good option. When making it, it is very important to follow the recipe. Each substance added must have a corresponding mass fraction. Small changes can ruin the product.
How can you restore dried acrylic
Acrylic is no less popular among artists. Packaged in small metal tubes, these paints often freeze and need to be resuscitated. Those who encounter this phenomenon do not know what to do for the first time. The problem is very easy to solve. But first you need to decide on the condition of the paintings. At first glance, it may seem that they have dried up, but in fact they have simply thickened.
If, with some effort, you can snag a little of the mixture with a brush, it has just frozen. In this case, the composition should stretch a little. You can soak the paint very quickly with a few drops of water or a special thinner.
What can be diluted
The marking on any acrylic paint indicates that it must be diluted with water and thoroughly mixed with a mixer before use. This is due to the fact that any mixture on acrylic has an increased density and density. If the instructions are not followed, the material will be difficult to apply. Thick paint materials extend behind roller or bakeware. Tools leave a mark that is difficult to repair. Also, this mixture will not stick so well to the wall. The formulations can be diluted with different substances.
Aqueous solution
Most often, paint materials are mixed with water before work, since it is the main component of the mixture.Depending on the type of work, the liquid is added in the following proportions:
- 10% by weight of the substance - this small volume makes it possible to prepare the painting materials well for the finishing application;
- 1:1 - obtain a composition for coarse application;
- 1:2 is a liquid substance suitable for wall repair and restoration.
- 1:5 is a liquid substance used for application to structural surfaces.
Special means
Pigments are special agents used to thin acrylic paints. All water-based acrylic emulsions are available as a white or transparent base. The combination of dyes will give the building material a new shade to taste. Pigmentation can improve the physical characteristics of the material.
Solvents
Acrylic enamels are diluted with special solvents, because with machine painting, dilution with water does not provide the necessary performance for the job. In addition to elasticity, when applied, solvents can increase the level of shine or, conversely, give a matte effect.
Using thinners increases strength, speeds up drying time, minimizes spillage and keeps air out.
Other paintings
Sometimes there are cases when there are remnants of several types of paints at once. Reluctance to go to the store for acrylic paint or curiosity of mind forces people to experiment, mixing different compositions. In this case, you need to look at the binder from which the paint material is made. In addition to acrylic, there are:
- silicate;
- silicone;
- oil.
If there are acrylic mixtures, but of different colors, you can make a paint out of them by adding water.However, the original tone will change. It is difficult to predict what shade will result from such a mixture.
In other cases, it is not recommended to mix materials with different composition. Because they are incompatible and do not dissolve in each other. As a result of such action, unusable paint material will be obtained. Upon application, one will notice that the liquid has separated into layers. And after application, there is a high probability that the coating will crack and peel off in a short time.
How to properly dilute, how to restore dried acrylic
After several years, stains, cracks or other irregularities may appear on the painted wall, spoiling the view. In this case, it is better to partially renew the surface with the same paint. But after taking it out of the closet, it turned out that the material had frozen. You can solve this problem with hot water. To do this, pieces of paint can be pierced with a needle and hot water can be poured. The procedure is repeated several times. First, the substance is warmed up. In this case, the water will have to be changed several times. This happens until the building material becomes homogeneous.
Solvents can be used in the same way. The second option is more preferable, since heating the paint spoils its performance.
Prevention of drying out
Unfortunately, acrylic-based paints and varnishes tend to harden quickly. The same goes for painting paintings. To prevent the acrylic from drying out so quickly, you must completely shut off the oxygen supply. Therefore, after completing the painting work, you need to tightly close the lid of the bucket or tube. When the palette is constantly open, you need to spray it periodically.
The most popular paints and varnishes are compounds based on polyacrylate. They are distinguished by their pleasant price, their coverage rate of 97% and their ease of application. Adheres firmly to mineral surfaces, metal or wood.
Polyacrylic materials have already proven their claimed high performance. Compositions based on it are distinguished by a large number of advantages. And the most important thing is the favorable price-performance ratio. For long-term use of this paint, storage conditions must be observed. If you follow the instructions, you can use the paints for over a year.
