Can you paint over acrylic paint?

At some point, the color will come to an end. This also applies to natural when using acrylic paints. But the knowledge is not so widespread. Therefore, the question often arises as to whether acrylic paint needs to be removed or painted over. Here we show you how to paint acrylic paint.

Although acrylic paints have been offered since the 1940s, knowledge about them is not common. That's easy to explain. Acrylic paints were offered for a long time mainly as an artist's paint as an alternative to oil paint. But in recent years, a strong awareness of environmental damage has prevailed. Also in terms of health damage caused by paints and varnishes, many consumers today think differently.

This looks different today

Thus, the toxicity of acrylic paint over many other colors depending on the product is completely negligible. Therefore, for example, contemporary children's paints are exclusively acrylic paints. But also in the craft and home improvement, acrylic paints enjoy great popularity. So acrylic paints are almost made for concrete.

However, the knowledge of acrylic paint is therefore not so widespread

However, acrylic paints should not be applied on every wall. What is advantageous with concrete can lead to structural damage on mineral substrates. Acrylic paint, when dry, makes an absolutely waterproof film. This way, concrete is efficiently protected against the weather. In the case of a mineral-based wall, however, this means that it is no longer open to diffusion, so the humidity can no longer regulate.

Painting over acrylic paint is possible

Not affected are, of course, small "artistic" paintings. Because acrylic paint is often used instead of wall tattoos or for the design of children's rooms and other rooms. Should then be repainted or the extract is pending, the question quickly arises as to how to deal with the acrylic paint. Removing acrylic paint is not easy.

Composition of acrylic paint

Although you can wash off acrylic paint, but only as long as the paint is still wet. Why this is so explains the composition of the acrylic paint:

  • color pigments
  • Binders (in the case of acrylic paint acrylic resin or acrylic binder)
  • Dilution (mostly water)
  • possibly additives and additives (for setting certain properties)

The acrylic resin molecules adhere to each other as the paint dries, so you can literally say that they interlock. Therefore, acrylic paint is so elastic on the one hand and can be painted over one another even in thick layers. On the other hand, that is the reason why the paint becomes water impermeable.

Coat acrylic paint with synthetic resin paints

However, this also means that the ingredients of other colors, such as of synthetic resin paints and paints) can no longer harm the completely dried acrylic paint. You can therefore paint acrylic paint without hesitation with other colors. With new acrylic paint you can paint over the old paint from acrylic paint anyway anytime.

Before painting: Acrylic paint must be completely dry

However, there are some important points to consider when going overboard. The old finish of acrylic paint must be completely dry. If, for example, a fresh wall painting made of acrylic paint is to be painted over, you first have to give the paint sufficient time to dry and harden. The manufacturers of acrylic paints assume a drying time of at least three days (the current weather conditions also play a role).

Also, roughen acrylic paint before painting

Besides, you've probably noticed that acrylic paint shines. This already indicates how high the density of the paint must be. In other words, the color surface is very smooth. So to make sure that a new painting, for example, based on synthetic resin paint or synthetic resin paint adheres well, the old paint should be at least roughened acrylic paint. Roasting briefly with sandpaper is quite sufficient. Then the Neuantrich can be applied quickly and quickly, so he will also hold.

Tips & Tricks

If you grind the acrylic paint, please do not forget to clean sanding and dust particles before painting. Especially when removing acrylic paint on wood or similar projects, it is important if no particle inclusions should be visible in the new paint.
