Gesso: The Ultimate Guide for Artists

on

If you are an artist, you must be familiar with the term "Gesso." Gesso is a primer made from a mixture of gypsum and binder, used to prepare surfaces for painting. It is the first layer applied to a canvas or board before starting any artwork. In this blog post, we will discuss the benefits of using Gesso and how it can enhance the quality of your paintings.

What is Gesso?

Gesso is a white paint-like substance that is applied to surfaces such as canvas, wood, and paper to prime them for painting. It is made by mixing gypsum or chalk with a binder such as glue, acrylic, or PVA. The purpose of Gesso is to provide a smooth, even, and absorbent surface for the paint to adhere to.

Types of Gesso

There are two main types of Gesso: traditional Gesso and acrylic Gesso. Traditional Gesso is made with animal glue and is commonly used by traditional painters. It is known for its absorbency and ability to hold paint well. However, it has a longer drying time and can be difficult to work with.

Acrylic Gesso, on the other hand, is made with acrylic polymers and is the most commonly used type of Gesso today. It dries quickly, is easy to apply, and is more flexible than traditional Gesso. It is also less prone to cracking and yellowing over time.

Benefits of using Gesso

  1. Improved Adhesion

The primary benefit of using Gesso is that it improves the adhesion of paint to the surface. When applied to a surface, Gesso creates a rough, porous layer that allows the paint to stick better. This is especially important for surfaces that are smooth, non-porous or have been previously painted.

  1. Enhanced Texture

Gesso can also be used to create texture on the surface of the painting. Depending on how it is applied, Gesso can create a smooth or rough surface that can add depth and interest to the artwork.

  1. Increased Durability

Gesso can help increase the durability of a painting by creating a barrier between the paint and the surface. This prevents the paint from being absorbed by the surface and reduces the risk of cracking or flaking over time.

  1. Improved Appearance

Gesso provides a clean, white surface that allows colors to appear more vibrant and true to life. This is especially important when using transparent or light-colored paints.

How to Apply Gesso

Applying Gesso is a straightforward process. Here are the steps to follow:

  1. Choose the type of Gesso you want to use.

  2. Select a surface to prime, such as a canvas or board.

  3. Use a clean, dry brush to apply a thin layer of Gesso to the surface. Apply in long, even strokes, working in one direction.

  4. Allow the first layer to dry completely before applying the second layer. Depending on the surface and the type of Gesso used, 2-3 layers may be necessary.

  5. Sand the surface lightly between layers if necessary to create a smoother surface.

  6. Allow the final layer of Gesso to dry completely before beginning your artwork.

Tips for Using Gesso

  1. Use a high-quality brush to apply Gesso. This will help create a smoother surface and reduce the risk of brush strokes showing through the paint.

  2. Apply Gesso in thin layers. Thick layers can crack or peel over time.

  3. Sand the surface lightly between layers if necessary to create a smoother surface.

  4. Allow each layer of Gesso to dry completely before applying the next.

 Gesso is an essential tool for any artist who wants to create high-quality paintings. It improves adhesion, enhances texture, increases durability, and improves the appearance of the painting. Whether you are a beginner or a professional artist, using Gesso can help you achieve the desired results in your artwork. By following the steps outlined above and the tips for using Gesso, you can create a smooth, even, and absorbent surface that will help your paint adhere better and look more vibrant. So, next time you start a painting, make sure to apply a layer of Gesso first to ensure the best possible outcome. Happy painting!
