Using masking fluid in watercolour
Step 1: Preparing watercolour paper
- Tape the watercolour paper onto a sturdy board
- Lightly sketch border lines and outline where the edge of the wave will be
Step 2: Using Masking Fluid
- Shake the masking fluid well and pour a small amount into a shallow container
- Use a liner brush to apply organic masking fluid shapes onto the paper, suggesting foam on the water
- Think about the natural movement of water as you apply the fluid
- Allow the masking fluid to dry overnight (do not speed-dry with a hairdryer, as it can damage the paper when removed)
Step 3: Watercolour ocean waves
- Before painting, test all colours on a separate sheet of watercolour paper, adjusting to suit your ocean vibes
- Mix Yellow Ochre and Titanium White to create a sandy colour
- Paint the lower portion of the paper where the sand will be, extending the tone up to the edge of the wave
- Lighten the mix and paint behind the wave, blending it halfway up the page to suggest shallow water
- Mix Sap Green and Cerulean Blue to create a very light green-blue tone
- Apply this colour from behind the wave to about halfway up the page
- Darken the mix with Phthalo Blue and layer in darker blue tones, allowing some lighter areas to show through
- Further darken the Phthalo Blue and use a fine brush to paint wavy lines over the existing blue areas
- These lines add movement and depth to the water
Step 4: How to remove masking fluid
- Once the painting is fully dry, gently remove the masking fluid using an adhesive eraser
- This will reveal the white areas that represent the foam of the waves
Step 5: Final touches
- Mix a very light grey and use it to add shadows to the front of the wave and any other areas needing depth
- Use white paint to enhance foam highlights and add texture to the water
