Acrylic paints instantly dry on the surface of the substrate. But quick drying is not always a useful property. In such cases, you can use a drying inhibitor for drying acrylic paints.
A moderator is called a thick gel-like mass without color (transparent). Glycol is present in the composition of such a mixture - a substance without a special smell, which helps moisture to linger longer in acrylic paints.
The moderator is considered indispensable in cases when it is necessary to work with a certain shade in order to get smooth transitions, transfer all halftones, gently mark shades, and also draw shadows. The drying time of acrylic paints, which can take from 30 minutes to 5 hours, depends on the volume of the added composition.
The additive during mixing does not affect the characteristics of the tint. Thanks to the moderator, the color acquires unprecedented brightness and a good texture.
When experimenting with auxiliary material, it should be understood that the amount of introduced moderator has a different effect on the behavior and the corresponding consistency of the resulting mass.
Undiluted colors are highly viscous. This will allow you to create a different texture, give a clearer relief to the paint layer, apply larger strokes. Such a coating will dry in 40 minutes. The diluted color scheme stretches perfectly after the brush. Drying time is 10 minutes.
Drying time increases with the gradual addition of a moderator. This will give lightness when applying color. Kohler will become supple, and the brush will glide smoothly over the surface.
The additive that promotes delayed drying is easily mixed in a ratio of 1: 4. In the process of manufacturing the composition does not form foam or bubbles. The layers applied with a palette knife (special spatula) have almost no difference in pasteurity from color without additives, so this tool will become much more mobile when working. Full drying occurs in 3 hours.
By increasing the amount of auxiliary material by exactly half, (with a ratio of moderator and acrylic material of 1: 2), it becomes possible to create a texture, and you can also start work with a spatula. In this case, the structure will be soft and streamlined in relief. Small bubbles may appear at the time of mixing. A thin layer of such a diluted color dries in 3 hours.
This acrylic material is carried easily. Drying time - one hour.
When proportionally combining an acrylic color with a moderator in a mixing ratio of 1: 1, a jelly-like mixture is obtained. The process itself is rather difficult. This composition is not suitable for a palette knife , but it will be easy to work with a brush due to the obtained jelly-like composition, creating free sliding on the canvas. The paint dries in 2 hours.
Various auxiliary materials add special properties to ordinary acrylic paints. Colors become transparent, liquid or thick, matte, shiny or opaque.
To give versatility, acrylic dyes are diluted with several separate additives at once. For example, a moderator is considered indispensable when you need to carefully work out the colors.
Supporting material will allow you to get smooth transitions of skin tones when writing a portrait.
Creating a haze
To get a "haze", the paint with auxiliary material is not mixed. Water and a moderator are added if it is necessary to paint a large surface of the embossing fabric (using a bag).
Do not add too much retarder to acrylic colors to prevent unwanted changes in paint composition. A large amount of auxiliary material contributes to the appearance of bubbles, slow mixing. You can add no more than 25% moderator of the total volume of the acrylic mixture. Only in this way will it be possible to maintain a brilliant shine, increased tolerance and the necessary color density.
The technique of adding retarders to paints is usually used by artists when creating acrylic paintings in watercolor. For artistic decoupage, a similar technique is rarely used.
- the brush is wetted in a special moderator;
- then wetted in paint;
- after that, smears are applied to the palette from top to bottom and from bottom to top. In the absence of a palette, plastic plates are used. This method will allow you to distribute the color on the fibers of the brush, mix the color with the moderator and see the resulting color;
- after that you can get to work.
If necessary, paints can always be diluted with water with the addition of a certain amount of moderator. The resulting composition must be thoroughly mixed. After the preparatory work is done, you should proceed directly to staining the base. To do this, use a brush or a special sponge. If desired, an impression is made, for example, using a packet.
An example of the use of a drying retarder for acrylic paints is given below.
