Can acrylic paint be used after drying?

If the acrylic paint is not opened, it will be stored for a longer time. If it is boring, you have no choice but to discard it. When it is not dry, add some water, fully mix the pigment and water, and then pour some water into the propylene, which is equivalent to sealing with water, which can prevent premature drying, but can not guarantee too long time.

If the oil paint is dry, it can be soaked with turpentine for a long time, but the paint will not be used. If the gouache is dry, you can cover the gouache with a wet cloth (add more water), then cover the box, place it overnight or longer, wait for the paint to soften, and then add an appropriate amount of water to turn it over and mix. Generally, the newly purchased toner box includes a thin sponge with the same size as the sponge box. After each use of the coating, immerse the sponge in water, and then put it into a box to make the coating not easy to dry.
