Framing Pastel Paintings: No Mat, No Problem

Framing pastel paintings without a mat is a growing trend among artists. Traditionally, pastel paintings are framed with a spacer between the artwork and the mat or glass to prevent pastel dust from collecting on the glass. However, advancements in sanded papers have reduced the occurrence of stray pastel particles, making it possible to frame pastel paintings directly against the glass, a technique known as passe-partout framing. Artists can also experiment with various glass alternatives, such as mist coats, gloss finishes, and natural glass products, to protect their pastel paintings without the need for a mat. The decision to use a mat or go mat-less depends on the artist's preference and the desired presentation of the artwork.

Use spacers to separate the painting from the glass

Spacers are a great way to separate a pastel painting from the glass in a frame without needing a mat. They are especially useful if you live in a humid environment, as moisture can become trapped between the glass and artwork, creating condensation and causing the artwork to stick to the glass.

There are a few different types of spacers available. The simplest option is a rectangular hollow tube, which is adhesive on one side and can be stuck to either the backing board or the glass. These spacers are made from PH-neutral plastic, which will not harm the artwork. They come in two finish options: glossy and matte. If you need a custom spacer, you can speak to your local framing shop about buying spacers in smaller amounts.

Another option is to use glass spacers, which are usually 1/8 inch. These spacers are placed between the glass and the painting, creating a small gap. This method may require additional steps for stability, such as using acid-free linen tape on an acid-free foam board.

When choosing a spacer, it is important to consider the colour. The colour of the spacer should match the artwork or the backing of the frame. If the artwork has many colours, the artist can choose black for a shadowed effect or white to let light into the corners of the frame.

To install the spacers, cut them to fit the sides of the glass, then peel back the tape to expose the adhesive and stick it to the outside of the glass. Place the glass on top of the painting, which should be centred on a non-acidic, pH-balanced backing board. For added stability, seal the glass to the backing using pH-neutral tape.

Using spacers is a great way to frame a pastel painting without a mat, ensuring the artwork is protected and preserved.

Seal the painting to the glass/spacer/backing to create a vacuum

Sealing the painting to the glass, spacer, and backing to create a vacuum is a helpful technique when framing a pastel painting without a mat. This technique, known as the French method or Passé Partout framing, helps to prevent moisture buildup and potential damage to the pastel. Here's a step-by-step guide on how to seal the painting to create a vacuum:

Prepare the Spacer:

Cut a spacer to fit the sides of the glass. The spacer can be made from a variety of materials, such as wood or acid-free foam board, and should be approximately 1/8 inch thick. Some sources suggest using a slightly thicker spacer, such as 1/4 inch econospacers, for added stability. The spacer can be attached to the glass with adhesive or tape.

Position the Painting:

Place the spacer-attached glass on top of the pastel painting. It is important to ensure that the painting is secure and will not move during the sealing process. You may want to attach the painting to a rigid backing board or use a method like the "Oil Painting Style" with a liner or invisible spacer to create space between the glass and the painting.

Seal the Edges:

Use pH-neutral tape, such as linen tape or framing tape, to seal the edges of the glass to the backing. Start by attaching the tape to the front edge of the glass and then carefully wrap it around the sides, adhering it to the backing board. This process creates a vacuum seal that helps protect the pastel from moisture and potential damage.

Handle with Care:

Always use both hands on either side of the frame when carrying a pastel painting. When not in a hanging position, keep the painting face up to prevent loose particles from falling onto the glass. Avoid placing pastel paintings in direct sunlight or humid environments, as these conditions can affect the stability of the medium.

By following these steps and taking the necessary precautions, you can successfully seal a pastel painting to the glass, spacer, and backing, creating a vacuum that helps preserve and display the artwork.

Use a French technique by placing the glass directly on the pastel

The French technique of framing a pastel painting involves placing the pastel directly against the glass. This method is also known as "passe-partout framing".

To use this technique, start by securing the pastel painting to a backing board. This can be done by using hinge tape, which involves securing tape sticky-side up beneath the four sides of the painting and then securing a piece of tape sticky-side down over the up-facing tape, wrapping it around the back of the backing board.

Next, clean the glass and secure it to the backing board. Place a strip of framer's tape at two opposing edges of the glass, then carefully settle the glass on top of the pastel painting. Press down on the glass in the middle of the painting as you secure one side with the tape, pressing hard along the edge of the glass and securing it behind the backing board. Repeat this step with two additional pieces of tape at the other ends.

Finally, fit the assembled piece into a wooden frame. This technique results in a tightly-packaged, secure pastel painting that can be displayed without the need for a spacer or mat.

While this method has been used successfully by many artists and can make the pastel look less like a print or poster, it is controversial. Some concerns include the possibility of the pastel adhering to the glass in humid climates, potential damage to the pastel surface during the framing process, and the exposure of the pastel to radical temperature changes, which can cause expansion and contraction cycles that rub the pastel against the glass.

Use a wide wood frame to make the pastel look less like a poster

Pastel paintings are traditionally presented with a mat and frame. However, many artists are now choosing to display their pastel works in wide wooden frames without mats. This style of presentation is attracting the attention of the canvas-buying public.

Using a wide wood frame can make a pastel painting look less like a poster. Posters and prints commonly have wide surrounding borders. By presenting a pastel painting in a wide wooden frame, the artwork demands the same respect often afforded to oil and acrylic paintings, which are typically displayed with wider frames.

When framing a pastel painting without a mat, spacers are often used to separate the pastel surface from the glass. This is because pastel dust can fall and collect at the bottom of the frame over time. Glass spacers are recommended, and these can be purchased or made from scrap board. The spacers are attached to the glass with framing tape, and the glass is then placed on top of the painting.

Another method for framing without a mat is to place the pastel directly against the glass, a technique known as the "French method". This method is controversial, as some believe that it may cause the pastel to adhere to the glass in humid climates or if the glass is damaged and needs to be replaced.

When choosing a frame, a well-made wooden frame can save money without sacrificing style.

Cut the pastel to fit the frame, attach a rigid backing board and add an acrylic spacer

Pastel paintings can be framed without mats by cutting the pastel to fit the frame, attaching a rigid backing board, and adding an acrylic spacer. This method ensures that the pastel is secured and protected without the need for a mat.

Firstly, cut the pastel to fit exactly within the frame rebate. This step ensures that the pastel aligns perfectly with the frame, creating a neat and precise appearance.

Next, attach the pastel to a rigid backing board. This provides a sturdy and stable base for the artwork, ensuring its durability and longevity. The backing board should be made of a rigid material, such as MDF or foamcore, to provide sufficient support.

Finally, add an acrylic spacer to the frame. The spacer serves as a protective barrier between the pastel and the glass, preventing any smudging or damage. It also creates a depth effect, enhancing the overall presentation of the artwork. The spacer can be cut to fit the sides of the glass, and adhesive can be used to secure it in place.

By following these steps, you can effectively frame a pastel painting without a mat, showcasing the artwork while ensuring its protection and preservation.
