How To Varnish Your LARGE Acrylic Painting

How do you achieve long-lasting protection for your large acrylic portrait?

Introduction

Varnishing your acrylic painting is an essential step to protect it and give it a professional finish. In this guide, we’ll cover how to varnish a large acrylic painting, ensuring your artwork looks its best and remains protected for years to come.

Why is varnishing your large acrylic portrait important?

Varnishing your painting not only enhances its appearance by evening out the sheen but also protects it from UV rays, dust, and scratches. It adds a professional touch, making your artwork look polished and complete.

Supplies You’ll Need

Before you start varnishing, gather the following supplies:

Varnishing Brush: A large 10-inch brush is ideal for covering large areas quickly and evenly.
Matte Varnish: Opt for a high-quality matte varnish. A satin finish can provide a subtle shine without being too glossy.
Container: Use a clean container for your varnish. An old yogurt container works well.
Stir Stick: Ensure the varnish is well-mixed before application.
Rag: Keep a rag handy for wiping off any drips.
Pipe Wrench: This might be necessary to open a stuck varnish container.

Preparation Steps

Stir the Varnish: Over time, varnish can separate. Stir it thoroughly with a stir stick to ensure it’s well-mixed. If stirring isn’t an option, gently shake the container.
Clean Your Canvas: Wipe off any dust or debris from your painting using a clean rag. This step is crucial to avoid trapping particles under the varnish.
Lay the Canvas Flat: Position your painting flat on a table to prevent drips and ensure an even application.

Applying the Varnish

Start Far Away: Begin varnishing from the farthest point on the painting and work your way towards yourself. This method helps avoid drips and ensures a smooth application.
Dip and Brush: Dip your brush into the varnish container, ensuring both sides are evenly coated. Start about a quarter of the way from the edge and brush across the canvas.
Smooth Strokes: Use long, smooth strokes to apply the varnish. Avoid overbrushing, which can cause streakiness.
Overlap Strokes: Slightly overlap each stroke to ensure even coverage. Reload your brush as needed.
Wipe Drips: Wipe off any drips that occur on the sides of the painting using a rag.

Tips and Techniques

Don’t Overbrush: Overbrushing can lead to cloudiness and streakiness. Apply the varnish in one or two smooth strokes and leave it to dry.
Keep a Wet Edge: Maintain a wet edge as you work to prevent the varnish from drying too quickly and causing streaks.
Check for Streaks: Pay extra attention to dark areas of the painting, where streaks are more visible.
Drying Time: Allow the varnish to dry for a few hours. It should be dry to the touch within an hour and fully dry within four hours, depending on the temperature and humidity.

Common varnishing your large acrylic portraits mistakes to avoid

Varnishing can be a straightforward process, but there are common mistakes that can be easily avoided with a bit of caution:

Skipping the Stirring: Always stir your varnish before application to avoid uneven sheen and consistency.
Overbrushing: Applying too many strokes can cause the varnish to become cloudy. Less is more in this case.
Incorrect Drying Position: Never dry your painting vertically. Always lay it flat to prevent drips and runs.
Ignoring Dust: Ensure your work area and canvas are dust-free before starting to varnish. Dust particles can become trapped and ruin the smooth finish.

Frequently asked questions about varnishing large acrylic paintings

1. What kind of varnish do I use?

For varnishing large acrylic paintings, I recommend using a matte varnish, specifically one that dries to a satin finish. I use a matte varnish from Nova Color, which comes in gallon jugs that I transfer into quart-sized containers for easier use. This type of varnish not only enhances the appearance of your painting but also provides UV protection and a professional finish.

2. What kind of brush?

A large brush is essential for varnishing large paintings effectively. I use a 10-inch Liquitex varnishing brush. This brush covers a lot of ground quickly and ensures an even application of the varnish. It’s important to have a brush that’s wide enough to make long, smooth strokes across your canvas.

3. Should I use an isolation coat?

In my process, I do not use an isolation coat. Instead, I treat the varnish layer as another layer of acrylic. The reason behind this is the flexibility to restore or touch up the painting if needed. Since the matte varnish is essentially clear acrylic without pigment, it can be painted over if any issues arise over time.

4. How should I apply the varnish?

To apply the varnish, follow these steps:

Start by wiping off any dust from the canvas with a clean brush or cloth.
Lay your canvas flat on a table to prevent drips.
Stir the varnish well to mix any separated components.
Pour a small amount of varnish into a container.
Dip your brush into the varnish and start applying it from the area farthest away from you, working your way inward.
Use long, even strokes and avoid overbrushing to prevent streakiness and cloudiness.
Overlap your strokes slightly and lift the brush at the end of each stroke to maintain a wet edge.
Allow the varnish to dry completely, which usually takes a few hours for a large painting.

5. Why should I varnish a painting in the first place?

Varnishing your painting serves several important purposes:

It enhances the overall appearance by evening out the sheen and bringing out the colors.
It provides a protective layer against UV rays, dust, and other environmental factors.
It gives your artwork a professional finish, making it more appealing to clients and viewers.
It helps preserve the painting over time, ensuring it looks its best for years to come.

6. How often should I varnish my paintings?

Once varnished, your painting typically does not need to be re-varnished. However, if the varnish gets damaged or wears off over time, you can apply another coat after proper cleaning.

7. Can I use the same varnish for all my paintings?

It depends on the finish you desire. Matte varnish provides a non-reflective finish, while gloss varnish gives it a shiny appearance. Choose the varnish based on your preference for each artwork.

8. What if I make a mistake while varnishing?

If you notice a mistake while the varnish is still wet, you can carefully remove it with a damp cloth and reapply it. Once dry, mistakes can be challenging to fix, so it’s best to apply varnish carefully and avoid overbrushing.

How To Build Depth And Shading In A Narrative Painting

Enhance depth and drama in your paintings with renaissance techniques

Creating a narrative painting that conveys a powerful story and emotion requires mastering depth and shading. In this tutorial, we will explore how to build up shading and depth in a portrait, focusing on the painting of King David dancing as the Ark of the Covenant enters Jerusalem. Using Renaissance techniques, we’ll transform a monochromatic underpainting into a vibrant, expressive work of art.

Understanding the Basics: The Underpainting

The foundation of this painting begins with a monochromatic underpainting, also known as a “grisaille.” This involves using just three tones: darks, highlights, and midtones. For this portrait, we used a combination of ultramarine blue, organic orange, Napthol red, and burnt sienna to develop the skin tones, contrasting them with the clothing.

How To Build Depth And Shading In A Narrative Painting

Preparing Your Palette

Start by setting up your palette with the following colors:

Raw Umber Dark
Burnt Sienna
Raw Sienna
Phthalo Blue
Ultramarine Blue
Alizarine Crimson
Napthol Red
Organic Orange
Indian Yellow
Titanium White

Step 1: Monochromatic Underpainting

Start with a monochromatic underpainting, using three different tones: dark tones, highlights, and midtones. This step is crucial as it sets the foundation for the colors and shading that will follow. For this painting, the underpainting is created using raw umber dark, focusing on capturing the facial expressions and basic forms.

Step 2: Adding Color Glazes

With the underpainting complete, begin adding color glazes to develop the skin tones and separate different elements of the painting.

Skin Tones:

Mix ultramarine blue, organic orange, and Naphthol red with a bit of burnt sienna.
Apply these glazes to create a natural skin tone, ensuring to differentiate the skin from the clothing.

Hair and Beard:

Use a mix of raw umber dark, ultramarine blue, and alizarine crimson to darken the beard and shadows inside the temple.
This mix creates a rich, dark hue that enhances the depth of the facial features.

Step 3: Enhancing Depth with Glazes

The key to achieving depth is the strategic placement of glazes. Use matte medium to thin your paint and create transparent layers.

Eyes and Eyebrows:

Apply a darker glaze to the eyes and eyebrows using raw umber dark mixed with ultramarine blue and alizarine crimson.
Focus the glaze on specific areas, such as the middle of the eyebrows, to create a sense of shading and depth.

Nose and Mouth:

Darken the nasal labial folds and the interior of the mouth with the same glaze mixture.
This step accentuates the expressions and adds realism to the painting.

Step 4: Balancing Shadows and Highlights

When placing glazes, ensure that the dark values are consistently applied throughout the painting. This consistency is crucial for creating a cohesive look.

Clothing and Background:

Identify areas in the reference photo where shadows naturally fall, such as above the sash and by the armpits.
Apply glazes to these areas to enhance the contrast and depth.

Structural Elements:

Darken areas within the background structure, such as the temple’s pillars, to balance the dark values in the figure.
Use short, choppy brush strokes to push the paint into the canvas weave, then smooth it out with longer strokes.

Step 5: Customizing Colors and Textures

To achieve the right temperature and tone, customize your black and grey hues by varying the mix of raw umber dark, ultramarine blue, and alizarine crimson.

Temperature Control:

Test the color mixture on a white card to gauge its warmth or coolness.
Adjust by adding more ultramarine blue for cooler tones or more raw umber dark and alizarine crimson for warmer hues.

Step 6: Final Touches

As you near completion, focus on the fine details and textures.

Facial Hair:

Add texture to the mustache and sideburns to ensure they blend naturally with the rest of the beard.
Use a dry brushing technique to create subtle gradations and shading on the perimeter edges of the face.

Clothing and Accessories:

Darken areas on the clothing that need more shadow to enhance the three-dimensional effect.
Use controlled brush strokes to ensure precision and consistency.

Tips and Techniques for Mastering Glazing

Layering: Build layers gradually to control the depth and richness of colors. Each layer should be thin and transparent.
Color Mixing: Experiment with different combinations of colors to create custom blacks and grays. This adds uniqueness to your painting.
Brush Pressure: Vary the pressure on your brush to achieve different textures. Light pressure can create a dry brushing effect, perfect for subtle shading.
Matte Medium: Use matte medium to thin your paint and create glazes. It helps in achieving smooth transitions and blending.
Reference Photos: Always use a reference photo to guide your shading and ensure realistic light and shadow play.

Building depth and shading in a narrative painting, like this portrait of King David, requires patience and strategic application of glazes. By following these steps and techniques, you can create paintings that not only tell a story but also captivate viewers with their depth and realism.

How to Add Color Glazes in Acrylic to Your Grisaille

Learn how to enhance your grisaille with color glazes for a vibrant finish

Introduction

Adding color glazes to a grisaille painting is a transformative technique that can infuse your artwork with vibrant hues and rich textures. This process, rooted in historical painting methods, allows artists to achieve a remarkable depth of color and detail. In this guide, we’ll explore the step-by-step method for applying color glazes over a grisaille base, helping you bring your acrylic paintings to life with stunning results.

Understanding Grisaille

Grisaille is a monochromatic painting technique using shades of gray to create a value study. Historically, Old Masters employed this method to establish the tonal structure of their paintings before applying color. This monochromatic layer acts as a foundation, providing a strong value structure that guides the application of subsequent color layers.

How to Add Color Glazes in Acrylic to Your Grisaille

Why Use Grisaille?

Using grisaille as a foundation that allows artists to focus on value and composition without being distracted by color. It’s an effective way to ensure that your painting has a strong structure before introducing color glazes.

Materials Needed

Acrylic Paints: Titanium White, Raw Umber, Burnt Sienna, Indian Yellow, Ultramarine Blue, Phthalo Blue, Napthol Red
Matte Medium: To mix with the paint for glazing
Brushes: Flat and round brushes for different applications
Palette: For mixing paints and mediums
White Card: For testing glaze colors

Step-by-Step Guide to Adding Color Glazes

Prepare Your Grisaille Base
Ensure your grisaille painting is fully dried before beginning the glazing process. The grisaille layer should have clear contrasts between light and dark areas, establishing a solid value foundation.
Mix Your Glaze
Glazing involves mixing a small amount of acrylic paint with a larger quantity of matte medium. The matte medium dilutes the paint, creating a translucent layer that allows the underlying grisaille to show through. For skin tones, mix Burnt Sienna with a touch of Organic Orange and Raw Sienna to create a warm, earthy color. For background elements, combine Raw Sienna and Indian Yellow for a warm, golden hue.
Apply the First Glaze Layer
Start by applying a thin glaze of the mixed color over specific areas, such as skin tones or clothing. Use a light brush with minimal pressure to ensure the glaze is even and translucent. For example, apply a faint Burnt Sienna glaze to the skin areas to introduce warmth and create subtle tonal variations.
Layering and Building Up Color
Allow each glaze layer to dry completely before applying subsequent layers. Build up color gradually, adjusting the intensity as needed. For example, apply additional layers of Raw Sienna to the background to deepen the color and create a more unified look. Incorporate cooler tones like Ultramarine Blue and Phthalo Blue for areas affected by the sky, adding a sense of atmosphere and depth.
Refining Details
Use a smaller brush to apply color glazes to specific details, such as shadows and highlights. For instance, use a mix of Napthol Red and Burnt Sienna for the sash, ensuring a warmer tone in the shadowed areas and a more vibrant color in the highlights. This approach helps to differentiate between various elements and adds richness to the painting.
Blending and Adjusting Colors
As you apply the glazes, step back frequently to assess the overall effect. Adjust colors as needed to ensure harmony and balance. For example, if the background appears too warm, tone it down with a cooler glaze. Conversely, enhance warm areas with additional glazes to achieve the desired effect.
Final Touches
After completing the glazing process, evaluate your painting for any final adjustments. Add finishing touches to enhance specific areas or correct any imbalances. Ensure that the color glazes blend seamlessly with the underlying grisaille, creating a cohesive and vibrant final piece.

Tips for Successful Glazing

Test Glazes First: Use a white card to test glaze mixtures and ensure the desired color and transparency.
Work in Thin Layers: Apply glazes in thin, translucent layers to maintain the depth and value of the grisaille layer.
Allow Drying Time: Ensure each glaze layer is completely dry before applying the next to avoid muddying the colors.
Use Appropriate Brushes: Choose brushes suitable for glazing to achieve smooth, even applications.

Incorporating color glazes into your grisaille paintings is a powerful technique that adds complexity and vibrancy to your artwork. By following these steps and employing careful color mixing and layering, you can achieve stunning results that bring your acrylic paintings to life. Experiment with different colors and glazes to discover unique effects and enhance your artistic skills.

How To Add Dark Contrast: Acrylic Grisaille Painting

Learn the grisaille that enhances depth and dimension with dark contrast in acrylic painting

Adding dark contrast to your painting is essential for creating depth and dimension, especially in grisaille painting. Grisaille is a monochromatic painting technique that uses shades of gray to create a detailed underpainting, which can then be glazed with color.

This method, reminiscent of the techniques used by the old masters like Caravaggio, allows artists to achieve a high level of realism and tonal complexity. In this tutorial, we will explore how to effectively add dark tonal values to your acrylic grisaille painting, enhancing your portrait with rich contrast.

How To Add Darks Contrast: Acrylic Grisaille Painting

Understanding Grisaille Painting

Grisaille painting involves creating a detailed monochromatic underpainting that serves as a foundation for further color glazes. The technique is particularly useful for developing a strong value structure in your painting. When working with shades of gray, you can focus on the tonal values without the distraction of color, ensuring a solid foundation for your final piece.

Materials Needed

Acrylic paints: raw umber, ultramarine blue, alizarine crimson, and titanium white
Matte medium
Brushes: Flat brushes (size 4), Round brushes (size 0 and 4)
Palette
Canvas or painting surface

Step-by-Step Guide on How to Add Darks to Your Acrylic Grisaille Painting

Step 1: Preparing the Underpainting

Initial Sketch: Begin with a detailed sketch of your subject on your painting surface. This will serve as your guide for the underpainting.
Ground Layer: Apply a thin, even layer of an earth-tone color (such as raw umber) to your canvas. This serves as the ground layer and helps unify the painting.
Highlight Layer: Using titanium white, add highlights to your sketch. This step helps establish the lightest areas in your painting, creating a clear distinction between different tonal values.

Step 2: Mixing the Dark Glaze

Palette Setup: On your palette, mix raw umber, ultramarine blue, and alizarine crimson. Use a larger amount of raw umber compared to the other two pigments.
Adding Medium: Incorporate matte medium into your mixture. The matte medium helps create a transparent glaze that you can layer over your painting without losing the underlying details.

Step 3: Applying the Dark Glaze

Glazing Technique: Start applying the dark glaze to the areas of your painting that you have designated as shadows. Use a flat brush for larger areas and a round brush for smaller, more detailed sections.
Creating Contrast: Focus on building three main tonal values: highlights, midtones, and shadows. This triad simplifies the process and ensures a balanced composition.
Detailing: Use a smaller round brush (size 0) for intricate details such as facial features, nostrils, and eyelids. This precision helps maintain the realism in your painting.

Step 4: Enhancing Shadows

Depth in Shadows: Darken the eyes, mouth, and other deep shadow areas to add more depth. These elements create a focal point and enhance the three-dimensionality of your subject.
Shading and Blending: Smoothly blend the dark glaze into the midtones to avoid harsh transitions. This creates a natural gradient and enhances the realism of your painting.

Step 5: Refining Details

Facial Features: Continue to refine the details on the face, focusing on the beard, mustache, and hair. Treat these elements as shapes with specific tonal values rather than individual features.
Clothing and Accessories: Add dark tonal values to the clothing and other accessories. This helps create a cohesive look and ensures that every part of your painting is harmonized in terms of contrast and depth.

Tips and Techniques

Consistency in Glaze: Ensure that your glaze mixture is consistent throughout the painting process. This prevents unwanted streaks and uneven application.
Layering: Apply multiple layers of glaze if necessary. Allow each layer to dry completely before adding another to achieve the desired depth.
Value Shapes: Start on recognizing and painting value shapes rather than specific details. This approach helps maintain the overall structure and coherence of the painting.
Patience and Precision: Take your time with the detailing process. Patience and precision are key to achieving a realistic and impactful final piece.

By learning this technique of adding dark contrast to acrylic grisaille paintings, you can significantly enhance the depth and dimension of your artwork. This method not only simplifies the painting process but also provides a solid foundation for further color glazes. With practice and attention to detail, you can create stunning, realistic paintings that capture the essence of your subject.
