The Complete Guide to Brush Techniques

Understanding Your Brushes: Tools of Expression

Before diving into techniques, it's crucial to understand the tools at your disposal. Different brushes create different effects, and knowing which brush to use for each technique is fundamental to successful painting.

Brush Shapes and Their Applications

Flat Brushes

Flat brushes have square or rectangular tips and are incredibly versatile:

• Coverage: Excellent for blocking in large areas and backgrounds
• Edges: Create sharp, clean lines when used sideways
• Texture: Can create various textures depending on pressure and technique
• Blending: Perfect for smooth colour transitions

Round Brushes

With pointed tips and full bellies, round brushes offer precision and versatility:

• Detail work: Excellent for fine lines and intricate details
• Organic shapes: Natural for painting curved forms and flowing lines
• Variable line weight: Pressure changes create lines from thin to thick
• Glazing: Perfect for transparent colour applications

Filbert Brushes

Combining the best of flat and round brushes with their oval shape:

• Soft edges: Create natural, organic edges without harsh lines
• Blending: Excellent for smooth colour transitions
• Versatility: Handle both detail work and broader coverage
• Portraiture: Ideal for painting skin tones and facial features

Brush Sizes: From Miniature to Mural

Brush sizes typically range from 000 (tiny) to 24 (large). The key is having a range that covers your needs:

• Small (sizes 0-4): Detail work, fine lines, precise colour placement
• Medium (sizes 6-12): General painting, most versatile for varied techniques
• Large (sizes 14+): Backgrounds, washes, broad coverage areas

Fundamental Brush Techniques

These basic techniques form the foundation of all advanced brushwork. Master these, and you'll have the skills to tackle any painting challenge.

The Basic Stroke

The foundation of all painting begins with proper brush handling:

• Grip: Hold the brush like a pencil for detailed work, further back for looser strokes
• Pressure: Light pressure for glazes, firm pressure for coverage
• Movement: Use your whole arm for large strokes, fingers for fine details
• Speed: Fast strokes for spontaneity, slow strokes for control

Loading the Brush

How you load paint onto your brush affects every stroke:

• Full loading: Saturate the brush with paint for maximum coverage
• Partial loading: Use less paint for more transparent applications
• Tip loading: Load only the tip for fine lines and details
• Double loading: Load two colours for instant colour mixing

Brush Pressure Variations

Varying pressure creates different effects and is crucial for expressive painting:

• Heavy pressure: Creates solid, opaque coverage and textured effects
• Medium pressure: Standard for most painting applications
• Light pressure: Perfect for glazes, highlights, and subtle details
• Variable pressure: Creates dynamic, expressive strokes with character

Advanced Application Techniques

Glazing: The Art of Transparent Layers

Glazing involves applying thin, transparent layers of paint over dried underlayers. This technique creates depth, luminosity, and subtle colour mixing that's impossible to achieve through direct painting.

Glazing Technique:

1. Ensure the underlying layer is completely dry
2. Thin your paint with medium (not water for oils, not too much water for acrylics)
3. Apply with light, even strokes using a soft brush
4. Work quickly to maintain wet edges
5. Allow to dry completely before adding additional glazes

Glazing Applications:

• Colour modification: Warm up or cool down existing colours
• Unity: Apply overall glazes to harmonise colour relationships
• Atmosphere: Create depth and atmospheric effects
• Luminosity: Build rich, glowing colours through layering

Scumbling: Broken Colour Technique

Scumbling involves applying opaque or semi-opaque paint over a dry underlayer using broken, irregular strokes. This allows the underlying colour to show through in places, creating vibrant optical mixing.

Scumbling Method:

• Use a dry brush with minimal paint
• Apply irregular, broken strokes
• Vary pressure to control coverage
• Allow underlying colours to show through

Scumbling Effects:

• Texture: Creates rough, natural surface textures
• Atmosphere: Perfect for clouds, fog, and atmospheric effects
• Age: Suggests weathered, aged surfaces
• Vibration: Creates lively, vibrating colour effects

Texture Creation Techniques

Texture adds tactile quality to your paintings, making them more engaging and realistic. Different brush techniques can simulate various surface qualities.

Impasto: Thick and Expressive

Impasto involves applying paint thickly so that brush or knife marks are visible. This technique adds dimension and catches light beautifully.

Impasto Applications:

• Highlights: Thick paint catches light for brilliant highlights
• Texture: Creates actual surface texture that can be felt
• Expression: Visible brushstrokes add emotional impact
• Focus: Draws attention to important areas

Dry Brush Techniques

Using a brush with minimal paint creates broken, textured marks perfect for specific effects:

Dry Brush Method:

1. Load brush with paint
2. Remove excess paint on a rag or palette
3. Apply with light pressure
4. Allow paper or canvas texture to break up the stroke

Dry Brush Effects:

• Wood grain: Perfect for painting weathered wood
• Fabric texture: Suggests woven materials
• Hair and fur: Creates realistic animal textures
• Aged surfaces: Implies wear and weathering

Stippling and Dabbing

These techniques involve applying paint with short, perpendicular strokes or dabs:

Stippling Technique:

• Hold brush perpendicular to surface
• Use short, quick dabbing motions
• Vary pressure for different effects
• Can be done with brush tip or side

Stippling Applications:

• Foliage: Perfect for painting leaves and bushes
• Texture: Creates rough, bumpy surface textures
• Pointillism: Build colours through optical mixing
• Atmosphere: Suggest particles in air like snow or rain

Blending and Smoothing Techniques

Smooth, seamless blending is essential for realistic painting and subtle colour transitions. These techniques help you achieve professional-quality gradations.

Wet-on-Wet Blending

Blending colours while both are still wet creates the smoothest transitions:

Wet-on-Wet Method:

1. Apply first colour
2. While still wet, apply second colour adjacent to the first
3. Use a clean, damp brush to blend the junction
4. Work quickly before paint begins to dry
5. Use gentle, overlapping strokes

Dry Blending

For more controlled blending, work between dried layers:

• Apply base colour and allow to dry
• Apply second colour with decreased opacity
• Use soft brush to blend edges
• Build up gradually for smooth transitions

Crosshatching with Brushes

While traditionally a drawing technique, brush crosshatching can create unique painting effects:

• Apply parallel strokes in one direction
• Layer perpendicular strokes over the first set
• Vary pressure and spacing for different effects
• Perfect for creating graduated tones and textures

Specialty Techniques and Effects

Feathering

Feathering creates soft, delicate edges perfect for clouds, smoke, or soft lighting:

• Use light pressure with brush tip
• Make quick, light strokes outward from the main shape
• Gradually decrease pressure as you move away
• Perfect for creating soft, natural edges

Sgraffito

Scratching through wet paint to reveal underlying layers:

• Apply base colour and allow to dry
• Apply second colour on top
• While second layer is wet, scratch through with brush handle
• Creates linear details and textural effects

Lifting Techniques

Removing paint while wet to create highlights and corrections:

• Blotting: Use clean, damp brush to lift paint
• Scraping: Use brush handle or palette knife
• Sponging: Natural sponge creates organic textures
• Paper towel: Quick corrections and cloud effects

Brush Care and Maintenance

Proper brush care extends their life and maintains their performance. Quality brushes are an investment that pays dividends when properly maintained.

Cleaning During Painting

• Colour changes: Clean thoroughly when switching colours
• Medium removal: Remove medium buildup regularly
• Paint buildup: Prevent paint from drying in ferrule
• Shape maintenance: Reshape brush tip after cleaning

End-of-Session Cleaning

1. Remove excess paint on rag or paper towel
2. Clean with appropriate solvent (turps for oils, water for acrylics)
3. Work soap into bristles gently
4. Rinse thoroughly until water runs clear
5. Reshape brush while damp
6. Lay flat to dry

Long-term Storage

• Store brushes with points up or laying flat
• Protect tips with brush guards or make your own
• Avoid storing in closed containers while damp
• Check periodically for damage or moth/insect damage
