Introduction

Gesso is a popular material used for preparing surfaces before painting. If you are an artist or someone who loves to do DIY projects, you may have heard of it. In this article, we will discuss the proper use of gesso in 2023.

What is Gesso?

Gesso is a primer used to prepare surfaces for painting. It is made of a mixture of glue and chalk, which creates a white, opaque, and absorbent surface. Gesso provides a smooth and even surface for painting, and it prevents the paint from soaking into the surface.

Types of Gesso

There are two types of gesso: acrylic gesso and traditional gesso. Acrylic gesso is easier to use and dries faster, while traditional gesso is more time-consuming and requires more preparation.

How to Apply Gesso

Before applying gesso, make sure that the surface is clean and free from dust, dirt, and grease. Use a clean and dry brush to apply gesso in thin, even layers. Let each layer dry completely before applying the next layer.

How Many Layers of Gesso?

The number of gesso layers to apply depends on the surface, the type of gesso, and the desired effect. For most surfaces, two to three layers of gesso are enough. However, if you want a smoother and more opaque surface, you can apply more layers.

How to Sand Gesso

After applying the final layer of gesso, let it dry completely. Then, use fine-grit sandpaper to sand the surface gently. Sanding will remove any bumps, roughness, or brush marks, and it will create a smooth surface for painting.

How to Prime Canvas with Gesso

To prime canvas with gesso, stretch the canvas tightly over a frame. Then, apply a thin layer of gesso using a brush or a roller. Let it dry completely, and then sand it gently. Repeat the process at least two more times, or until you achieve the desired effect.

How to Use Colored Gesso

Colored gesso is a type of gesso that comes in various colors, such as black, gray, red, and blue. Colored gesso can be used to create a colored ground for painting, or to add a tint to the surface. Apply colored gesso in the same way as white gesso.

How to Store Gesso

Gesso should be stored in a cool and dry place, away from direct sunlight and heat. Make sure that the lid is tightly closed to prevent the gesso from drying out. Gesso has a long shelf life, but it may thicken over time. If the gesso becomes too thick, add a few drops of water and stir well.

Conclusion

Gesso is an essential material for preparing surfaces for painting. By following the proper steps for using gesso, you can achieve a smooth, even, and opaque surface for your artwork. Whether you are a beginner or an experienced artist, gesso can help you create beautiful and lasting paintings.
