About MM37 Matisse Medium

MM37 Matisse Self Leveling Medium is a clear product that when applied to a surface or as a paint additive will automatically spread and create a smooth, glossy finish with minimal surface texture. It is ideal for high gloss thick varnishing, pouring and marbling techniques. Apply with a brush, palette knife or jug. Can be tinted with Matisse Flow Acrylics or Matisse Inks.

Application / Use

There are many application methods for this product, providing the artists with a myriad of possibilities.

It can be tinted with the addition of Matisse Ink or Matisse Flow Acrylic Paint. Using ink will maintain transparency and a glossy finish, while the use of acrylic paint will make the final result more opaque and less glossy.
Only a small amount (less than 10%) of either paint or ink is required.  As this product is white in the container, the addition of colour will initially produce a pastel blend, but this will develop into a bright, transparent colour after the drying process is completed. This drying time must be taken into account when applying multiple layers of colour if the artist wants to see how the colour will develop between layers.

If Self Leveling Medium has been applied and bubbles have developed (while the coating is still wet), a pin can be used to release the air from larger bubbles. This is not always practical for multiple, smaller ones. These may be able to be removed with a spray application of isopropyl alcohol, which is readily available in pharmacies. After decanting into a small spray bottle lightly spray the isopropyl alcohol onto the wet surface. It will immediately break the surface tension and release the bubbles. Be aware that the medium itself will also spread slightly.

In Mixed Media

MM37 Self Leveling Medium can also be used to create transparent polymer/acrylic layers that can be peeled away and added to mix media artworks when applied to a non stick surface such as PP (Polypropylene) or PE (Polyethylene) plastic sheets.


After colour has been added to the medium  and left to stand, it can be poured onto plastic ring binder sleeves and left to dry. Once dry and peeled, the soft, plastic-like formations can also be easily cut with scissors to any desired shape. Unfortunately, acetate sheets or glass surfaces are not recommended for this process as the medium will adhere to the surface, therefore standard plastic ring binder sheets are ideal.


Small objects such as beads and thread can also be embedded into the surface. Simply add the objects to the wet medium and allow to dry.

In Varnishing

MM37 Self Leveling Medium is archival and can be used over any acrylic painted surface (as long as it is thoroughly dry) to create a high gloss, resin-like coat of varnish. It can be applied by pouring but this technique is recommended only for the application on rigid substrates. It is impotrtant to remember that since Matisse MM37 is a water based medium, it is not suitable for use over oil painted surfaces. The use of a brush is recommended when varnishing flexible surfaces to avoid “pulling” due to surface tension of the product.


Create a masking tape border around the edges of the board to keep the medium from dripping down the sides, and leave the tape in place until the medium is dry. Then, simply pour on and gently roll the board to allow the medium to flow and coat the entire surface. Let this coat of medium dry and remove the tape. Any ridges that formed along the edge against the tape wall can be trimmed with a scalpel or hobby knife. Larger areas that cannot be rolled may need to have the medium gently brushed over the surface.
A soft-bristle brush is recommended and a light touch is required as over brushing and manipulating the medium excessively for long periods as it is curing, can affect the smoothness of the finish. In terms of application, one coat of MM37 Self Leveling Medium gives the same finish as approximately two to three layers of a standard acrylic gloss varnish.

This product does not need to be thinned with water or through the addition of mediums. It can only be used straight from the container. DO NOT ALLOW TO FREEZE.

Drying Time

The thickness of application of this product will determine the length of drying time. For a thin coat, a standard estimation is 48hrs, but prevailing atmospheric conditions upon application may influence drying time (humidity, heat, cold, etc.).

 WARNING do not force dry or use in temperatures above 30℃ as premature skinning may occur trapping water in the coating resulting in an opaque or cloudy finish.


Matisse MM37 has a HI-Gloss finish and may become more so with thicker or multiple applications.


Clean brushes, palette knives, jugs and hands with warm, soapy water.
