Gouache painting is a rewarding and versatile medium that bridges the gap between acrylic and watercolor. With its rich colour, matte finish, and the unique ability to be reworked with water, gouache offers beginners a forgiving and expressive entry into the world of painting. This guide not only addresses common questions and concerns but also emphasises the importance of using quality materials, ensuring that you are well-prepared and informed for your painting journey.
Unique Properties of Gouache
Gouache paint is known for its matte, velvety finish and opaque colour payoff. Unlike watercolour, gouache covers layers and hides brush marks. This unique medium dries quickly, can be reactivated with water, and is ideal for flat colour areas and fine details.
Artists love gouache painting for its adaptability. You can create bold layers, smooth washes, or soft blending depending on water control.
Why Is My Gouache Painting Crumbling?
Crumbling happens when gouache is applied too thickly or to an unsuitable surface. Gouache needs an absorbent base to adhere correctly.
If you use too little water or apply it over glossy or non-absorbent paper, the paint may lift or flake. Always paint in controlled layers and test your surface before applying the paint.
Is Gouache Permanent?
No, gouache is not permanent unless sealed. It can be reactivated with water, even after drying, which allows for corrections.
However, this also means that your artwork is vulnerable to moisture and damage if it is not protected. If permanence is a concern, consider sealing your finished work.
Why Does Gouache Dry Matte?
Gouache dries to a matte finish due to its composition. It contains larger pigment particles and less binder than acrylic or watercolour.
This results in a beautiful, non-reflective surface, ideal for scanning or photographing your artwork. Matte finishes also allow colours to appear more uniform when dry.
What Is Acrylic Gouache? How Is It Different?
Acrylic gouache is a hybrid medium. It has the creamy texture and matte look of traditional gouache but becomes permanent when dry.
Unlike regular gouache painting, acrylic gouache cannot be reactivated with water. This provides greater permanence and eliminates the ability to rework areas later.
Does Gouache Contain Chalk?
Yes, traditional gouache may contain chalk or a white pigment, such as calcium carbonate. This increases opacity and gives the signature matte finish it is known for.
Cheaper brands may add excessive chalk, which can affect the richness of colour and flexibility. Invest in artist-grade gouache for more consistent results.
Can You Combine Gouache and Watercolour?
Absolutely. Gouache and watercolour work beautifully together. Use gouache for highlights or solid colour areas over your watercolour base.
This combination adds depth and contrast to your artwork. Many artists enjoy using gouache to brighten or correct their watercolour pieces.
Can You Use Gouache Like Watercolour?
Yes, but expect differences. Gouache can be diluted to behave like watercolour, offering light blends and soft washes.
However, it dries more quickly and with a flat finish. When used lightly, gouache painting mimics watercolour but allows for more effortless layering.
Why Is Some Gouache More Transparent Than Others?
Pigment type and formulation determine gouache transparency. Lighter or synthetic pigments may appear more transparent, even if the label indicates they are opaque.
Some brands use more binder and less pigment, which can also cause transparency—test swatches before starting your gouache painting to understand coverage.
How Do You Seal or Varnish Gouache?
Use caution. Gouache is water-soluble, so applying a wet varnish can ruin your work. Use a spray fixative designed for gouache.
Ensure the painting is completely dry, and test the spray first. Sealing protects your gouache painting from fading, moisture and smudging.
What Is the Watery Stuff Coming Out of My Gouache Tube?
This is binder separation, a common occurrence in older or unused tubes. The binder, a substance that helps keep pigments suspended, can separate from the pigment over time, leading to a watery layer on top. Simply knead the tube or mix it on your palette to recombine the binder with the pigment.
The binder helps keep pigments suspended. If not mixed, your gouache may behave inconsistently. Always check paint consistency before applying.
How Do You Travel With Gouache?
Gouache is great for travel. Use a palette with dry wells or pour small amounts into airtight pans that can be reactivated later.
Avoid packing large tubes unless secure. Bring a water brush, a small palette, and a sealed container for water and rinsing.
Can You Paint With Dried Gouache?
Yes, dried gouache can be rehydrated with water and used again. This makes it ideal for sustainable painting and travel kits.
Rewetting does not affect pigment quality but remember to seal your palette between sessions to keep dust out.
Does Granulating Gouache Exist?
Not traditionally. Granulation is more common in watercolours due to the settling of pigment. However, some artist-grade gouache can display granulating effects.
It depends on the pigment used. For texture lovers, layering gouache over granulating watercolour creates subtle effects and visual interest.
How Do You Stop Gouache From Drying Out While Painting?
Keep your palette misted with a fine spray bottle. Use a stay-wet palette, or cover your paint with a damp paper towel.
Work in smaller batches and avoid placing large amounts of paint on an open surface. Humid environments also help slow drying.
What Is the Best Palette for Gouache?
Choose a palette with a lid or airtight seal to preserve moisture. Ceramic palettes are excellent for mixing and easy to clean.
Plastic palettes work well, too, especially those with wells and a tight-fitting cover. Avoid overly absorbent surfaces, which can leach moisture from the paint.
What Brushes Should You Use for Gouache?
Use synthetic brushes for control, durability, and spring. Gouache paint is thicker than watercolour and benefits from firm bristles.
Flat, filbert, and round shapes offer variety. You can use soft watercolour brushes, but they may not work as well with thicker paint.
Can You Paint with Gouache on Any Paper?
Not all paper is suitable. Gouache works best on heavyweight, slightly textured watercolour paper (minimum 200gsm or higher).
Hot-pressed paper offers a smooth finish, while cold-pressed paper provides a more textured feel. Avoid using thin paper that may buckle or tear when exposed to wet conditions.
