Tips

  • Work quickly with masking fluid to avoid it drying.
  • Use colored masking fluid for easier visibility.
  • Be gentle when removing masking fluid to avoid tearing the paper.
  • Use a damp tissue to effectively soften and lift out highlights.
  • The wet-on-wet technique is most effective on 100% cotton paper.

Common Mistakes to Avoid

1. Insufficient Water

Reason: Lack of water leads to harsh, dry edges and difficulty blending colors smoothly on the wet-on-wet surface.
Solution: Use a well-saturated brush and keep your palette and canvas adequately moistened.

2. Overworking the Paint

Reason: Excessive blending or touching can disturb the initial wet-on-wet effect, resulting in muddiness and loss of vibrancy.
Solution: Work quickly and confidently, trusting the natural flow and blending of the wet paint.

3. Incorrect Masking Fluid Application

Reason: Improper application, like applying too thickly or leaving it on for too long, can cause paint to lift or create uneven edges around masked areas.
Solution: Apply masking fluid thinly and evenly, remove it before the paint fully dries, and lift gently.

FAQs

What is the best type of paint to use for wet-on-wet seascape painting?
Watercolor or acrylic paints work best for wet-on-wet techniques. Watercolor offers a more translucent and delicate effect, while acrylics allow for quicker drying times and greater control if you prefer a bolder look. Both require a certain fluidity to work well with this method.
