The problem lies in the fact that the paint you have chosen cannot cover the color that pre-existed on the surface.

Reasons:

• Application of the paint with a thickness less than recommended
• Use of low quality paint
• Use of poor quality or inappropriate tools (roller, brush)
• Excessive thinning of the paint
• Improper priming of the surface
• Insufficient mixing of the paint

Solution:

In case the existing background color is too dark and you use a substrate, tint it in a similar shade to that of the final color. Choose ER-LAC colors that ensure excellent coverage. Use the correct tools and follow the instructions for thinning and applying the paint.
