- Canvas should be primed before painting to protect the fibers from oil and prevent discoloration.
- Choose a high-quality canvas made of linen or cotton, stretched tightly over a sturdy frame.
- If using pre-primed canvas, lightly sand it with fine-grit sandpaper to create a smoother surface for painting.
- If priming the canvas yourself, use gesso primer and apply at least two coats, allowing each coat to dry completely before applying the next.
- Apply the first coat of primer in one direction and the second coat in the opposite direction to create a crosshatch pattern that will provide better adhesion for paint.
- Allow the final coat of primer to dry for at least 24 hours before beginning to paint.

How to Prepare Canvas for Oil Painting – The Quick Answer:
To prepare your canvas for oil painting, you’ll need a canvas specifically made for oil painting, stretcher bars, gesso (pre-made or homemade), and painting knives. Once you have all the necessary materials, follow these simple steps to stretch and prime your canvas: assemble your stretcher bars, stretch your canvas over the bars, staple it in place, and apply gesso using a painting knife.
Preparing Your Canvas for Oil Painting: Materials You’ll Need
Before you start stretching and priming your canvas, make sure you have all the necessary materials. Here are the things that you will need:
Canvas:
The first thing you’ll need is a canvas. Make sure to choose one made specifically for oil painting, as these canvases are primed with a gesso that is suitable for oil paint.
Stretcher Bars:
To stretch your canvas properly, you will need stretcher bars. These come in different sizes and lengths and can be found at most art supply stores or online.
Gesso:
Gesso is an important material for priming your canvas. It creates a surface that is more receptive to oil paint and protects the fibers of the canvas from being damaged by the oils. You can purchase gesso pre-made or make it yourself using traditional recipes.
Painting Knives:
Painting knives are useful tools for applying gesso and paint to your canvas. They come in different shapes and sizes, so it’s good to have a few on hand to use for different techniques.
List of Materials You Will Need:
- Canvas
- Stretcher bars
- Gesso (pre-made or homemade)
- Painting knives
- Sandpaper (optional)
- Dust mask (optional)
Step-by-Step Guide: How to Stretch and Prime Your Canvas for Oil Painting
Stretching and priming your own canvas can seem daunting, but it’s actually quite simple once you get the hang of it. Here’s how to do it:
Step 1: Assemble Your Stretcher Bars
Take your stretcher bars and assemble them into the desired size and shape for your canvas.
Step 2: Stretch Your Canvas
Lay your canvas on a flat surface with the wrong side facing up. Place your assembled stretcher bars on top of the canvas, making sure the bars are centered. Fold the edges of the canvas over the stretcher bars and staple them in place, starting from the center of each side and working your way outwards.
Step 3: Apply Gesso to Your Canvas
Once your canvas is stretched, it’s time to apply gesso. Use a painting knife to apply an even layer of gesso to the entire surface of the canvas. Make sure to let it dry completely before applying another coat.
Steps for Stretching and Priming Your Canvas:
- Assemble stretcher bars
- Lay canvas on flat surface with wrong side facing up
- Place stretcher bars on top of canvas, making sure they’re centered
- Fold edges of canvas over stretcher bars and staple in place starting from center of each side
- Apply an even layer of gesso to entire surface using a painting knife
- Let dry completely before applying another coat if necessary
Choosing the Right Primer for Oil Painting on Canvas
When it comes to priming your canvas for oil painting, there are several options available. Here are some of the most popular:
Gesso:
Gesso is a traditional primer made from a mixture of chalk, gypsum, and binder (usually acrylic). It creates a smooth surface that is ideal for oil paint application.
Oil Ground:
Oil ground is a primer specifically designed for oil painting. It is made from linseed oil and white pigment, and it creates a smooth surface that is perfect for layering oil paint.
Acrylic Gesso:
Acrylic gesso is a newer type of primer that is gaining popularity among artists. It is made from acrylic resin and can be used with both acrylic and oil paints.

Do You Need to Prime Your Canvas Before Painting with Oils?
In short, yes. Priming your canvas before painting with oils is essential. The primer creates a barrier between the canvas fibers and the oil paint, protecting the canvas from being damaged over time.
The primer also provides a surface that is more receptive to oil paint, allowing the paint to adhere better and creating a smoother finish.
It’s important to note that not all canvases come pre-primed, so if you’re using an unprimed canvas, make sure to prime it yourself before painting.
Drying Time: How Long Should You Let the Primer Dry Before Starting to Paint?
Drying time for your primer will depend on several factors, including the type of primer you use, how thickly you apply it, and the humidity in your workspace. As a general rule of thumb, let your first coat dry completely before applying another coat or starting to paint.
Most primers will dry within 24 hours if applied thinly. However, if you apply multiple coats or thicker coats of gesso or oil ground, drying time may take longer. Be patient and make sure each coat has dried completely before moving on.
To Sand or Not to Sand? Tips for Preparing a Smooth Surface on Your Primed Canvas
Sanding your primed canvas can help create a smoother surface for painting. However, it’s not always necessary, and it really depends on personal preference.
If you decide to sand your canvas, make sure to do it after the primer has dried completely. Use a fine-grit sandpaper and sand lightly in a circular motion until you achieve the desired smoothness.
It’s important to note that sanding too much or too hard can damage the fibers of the canvas, so be gentle and take your time.
If you prefer a bit of texture in your paintings, skip sanding altogether. The brushstrokes and texture of the canvas can add character and depth to your work.
Preventing Discoloration: How to Keep Oil Paint from Soaking Too Deeply into the Canvas
Oil paint has a tendency to soak deeply into unprimed or poorly primed canvases, which can lead to discoloration over time. To prevent this from happening, make sure to apply enough primer and let each coat dry completely before painting.
Another useful trick is to use an isolation coat between your primer and paint layers. An isolation coat is simply a layer of clear acrylic medium that creates a barrier between the paint and primer layers. This prevents oil from soaking too deeply into the canvas fibers and helps keep colors true over time.
Creating an Even Base Layer: Techniques for Applying Oil Paint to a Prepared Canvas
When it comes to applying oil paint to your prepared canvas, there are several techniques you can use:
Underpainting:
An underpainting is a layer of thinly applied paint that serves as a base for subsequent layers of thicker paint. It helps establish values and tones early on in the painting process.
Blocking In:
Blocking in involves laying down large areas of color to establish the basic composition and color palette of your painting.
Layering:
Layering involves building up layers of paint to create depth, texture, and dimension in your painting. This technique is often used in conjunction with an underpainting.
List of Techniques for Applying Oil Paint:
- Underpainting
- Blocking In
- Layering
Experiment with these techniques to find the one that works best for you and your painting style. Remember to let each layer dry completely before adding another, and have fun with it!
In conclusion, preparing your canvas properly is a crucial step in achieving great results when oil painting. By following the simple steps outlined in this guide, you can ensure that your canvas is ready for paint and will provide a stable and durable surface for your artwork.
Frequently Asked Questions about How to Prepare Canvas for Oil Painting
Do you have to prime canvas for oil?
Preparing the canvas, known as “priming,” is necessary before applying oil paint, unlike acrylic or watercolor painting. This process remains the same regardless of whether you are using a pre-stretched canvas or stretching your own.
Should I wet my canvas before oil painting?
It is important to remember that there are no set rules when it comes to creating art. You have the choice to wet the canvas before painting or to skip this step. Many artists choose to wet the back of the canvas before painting with acrylics to keep the paint wet for longer and to achieve better color blending.
Is store bought canvas already primed?
The canvases available at most craft stores are typically already prepared for acrylic painting with primer applied. If the canvas is bright white in color, it is ready to be used for painting.
Can oil paint be safely applied to raw canvas?
What happens if you paint on raw canvas? It will rot! Oil paint should never come into direct contact with the fiber or the canvas will eventually rot, become weak, brittle and crumbly.Jun 15, 2020
Is gesso necessary for oil painting?
Before painting on an unprimed or linen canvas, it is suggested that you apply an oil-compatible gesso primer to the surface. This primer will prevent the paint from seeping into the canvas fibers and causing damage.
Do you wet the brush before using oil paint?
Prior to using the brush, shake off any accumulated dust by flicking the bristles back and forth. If you are using water-based paint, dampen the brush with water; for oil-based paint, use mineral turpentine. Be sure to remove any excess liquid from the brush before starting to paint.
