You can cover acrylic paint with several methods, depending on the surface and desired outcome. The beauty of acrylics is that once dry, you can paint directly over them, although multiple layers may be needed for complete coverage. However, if the acrylic paint is sealed, or you desire a highly reliable coverage, additional steps are necessary.
Methods for Covering Acrylic Paint
-
Directly Painting Over: For unsealed acrylics, you can apply another layer of acrylic paint directly. This is the simplest method. To completely cover a color, especially a dark one, you might need two or more coats. (Reddit, Will Kemp Art School)
-
Using a Primer: If the acrylic paint is sealed or you're working with a porous surface, applying a primer before painting is crucial. A primer creates an even surface for the new paint to adhere to, preventing peeling. (Quora, DIY Stack Exchange)
-
Sanding: For a sealed acrylic surface, light sanding can help the new paint adhere better. This roughens the surface, improving the primer’s grip. Remember to always wear appropriate safety gear when sanding. (Reference 1)
-
Gesso: Applying gesso, a primer specifically for painting, is an excellent way to cover the existing acrylic layer and prepare the surface for a fresh painting. It offers excellent adhesion and creates a smooth, even base for new paint. (Step By Step Painting)
Types of Paint to Use
You can typically paint over acrylics with both water-based and oil-based paints. (Reference 1) However, you cannot cover an oil painting with acrylics; the acrylics will likely peel. (Milan Art Institute)
Important Considerations
- Surface Preparation: Always ensure the acrylic paint is completely dry before attempting to cover it. Proper surface preparation is vital for optimal results.
- Number of Coats: Depending on the color and opacity of the new paint, multiple coats may be necessary for complete coverage.
- Sealer: If you want to preserve your new painting, consider using a sealer once it's completely dry. (The Social Easel, WetCanvas)
