If you mix paint with water, it will become more diluted or thinned out. The level of dilution will depend on the amount of water added and the type of paint being used. Adding water to paint can affect its consistency, color, and coverage.
If too much water is added, the paint may lose its ability to adhere to the surface and can become streaky or start to drip when applied. This is particularly true with paints that are meant to be more transparent and non-opaque.
However, if you mix paint with water in a controlled and precise manner, you can actually achieve interesting washes or gradients of colors. In fact, painter often use water to manipulate the consistency and coverage of their paints on wall.
1. Loosing consistency
2. Color starts to fading
3. Paint become more transparent
4. Dripping and splatter
5. Less adhesion to wall
6. Surface looks uneven
