ARA Cassein Binder is a modern alternative to rabbit glue. It gives a strong flexible film for the preparation of the canvas. Casein acrylic binder is insensitive to moisture after drying. Very much a marriage of the latest technical developments and traditional materials. This is an alternative to acrylic primers for fabric surfaces. It is not susceptible to dampness which results in the surface tension remaining consistent. We have spoken to a number of continental professional artists and they rate this primer highly.
Apply 2 or 3 thin layers to the required surface. To dilute, add one equal part of water. For chalk walls, it is 1 part casein binder to 9 parts water.
