How to Master Wet-on-Wet with a Mop Brush

Looking to create dreamy, flowing watercolour effects? A mop brush is your best mate when it comes to mastering the wet-on-wet technique. Its soft, rounded bristles are ideal for laying down big, even washes – no streaks or hard edges in sight.

Here’s how to make the most of it:

1. Start by loading your mop brush with plenty of water and a diluted mix of your chosen watercolour.
2. Work onto damp or wet paper; that’s where the real magic happens. The wetter the surface, the more the paint will bloom and blend.
3. Use broad, gentle strokes to spread the colour. Mop brushes hold a lot of water, so take advantage of their sweeping coverage.
4. Aim for soft, seamless transitions – this technique is all about fluid movement and letting the water do the work.
5. Try layering and blending colours while the paper is still wet for stunning effects.
6. Experiment with paper types – different textures will give you different results, so have fun testing what works for your style.

With a bit of practice, you’ll be creating glowing skies, fluid gradients, and moody backgrounds in no time. Wet-on-wet is a wonderful technique to explore, and the mop brush makes it easy to get started.
