Can I repaint my acrylic painting

Fix acrylic paint

Why a fixative at all?

Many paint applications are not particularly mechanically stressable. For example, in pastel or watercolor painting or pencil drawings. Fixations are carried out in the following ways, among others:

  • when the colors are easy to remove mechanically
  • when colors adhere only with difficulty, even without direct mechanical influences
  • when colors are sensitive to water or moisture
  • if the colors are to be protected against UV radiation
  • to adapt different color properties to each other

Basic properties of acrylic paints

Acrylic paints are initially water-soluble, which means they can be thinned with water. Layers can be removed with water-based acrylic paints. However, only as long as they have not yet dried. Once acrylic paints have dried, they can no longer be dissolved with water. Acrylic paints are not particularly resistant to mechanical loads, but they are still considerably more than, for example, pencil sketches or watercolors.

Not every acrylic paint needs to be fixed

Therefore, a fixative is not really necessary initially. However, different painting techniques are used, especially with acrylic paints. Acrylic paints can be diluted with water to such an extent that they can only be applied like a glaze. On the other hand, acrylic paints can be thickened with the addition of acrylic resin (acrylic binder) so that they are applied in a paste-like manner.

When it makes sense to fix acrylic paints

Depending on the color and the technology used, it can therefore occur in an overall picture that some colors appear matt and others have a high gloss. This can be homogenized with a fixative. As a result, the different colors no longer appear partially glossy and matt, but rather evenly.

In the case of extremely dilute acrylic paints that are only applied very thinly, UV radiation can also affect the color pigments. Fixing these colors helps and maintains color depth and brilliance in the long term.

Agent for fixing acrylic paints

You can use different means to fix it. Some hobby painters swear by hairspray, while others think it would be more suitable for watercolors and pencil drawings. The specialist trade also offers a range of fixatives. Alcohol is used as a dilution, as it is quickly volatile and the fixative dries quickly. There are also various resins that have been diluted. Varnish can also be used explicitly for acrylic paints.

Fixing acrylic paints on everyday objects

If, on the other hand, you want to paint everyday objects with acrylic paint, for example with acrylic paints for furniture, you can also fix the color with a transparent synthetic resin. This significantly reduces abrasion, as synthetic resin paints are extremely resistant.

Ready-made fixatives are available in either a spray can or a glass bottle. The latter are then sprayed on with a mouth blow piece.
