Matisse Acrylic Medium MM3 - Surface Tension Breaker 250ml

Matisse Acrylic Medium MM3 - Surface Tension Breaker 250ml. Using MM3 Surface Tension Breaker within a water and paint mixture will greatly facilitate colour penetration into absorbent paper or fabric grounds, i.e. raw canvas. It is a valuable additive in stain painting techniques and water wash applications when working on hand-pressed watercolour paper or absorbent, bleached but unprimed canvas. For best results, the MM3 Surface Tension Breaker should always be pre-diluted with the quantity of water used to thin the paint. Prepare a stock jar of water with 5-10% MM3 Surface Tension Breaker and use this water for the painting. MM7 Polymer Gloss Varnish (Gloss Medium) and the other mediums, such as MM4 Gel Medium and MM9 Acrylic Painting Medium, can also be treated with MM3, all sold separately. Unprimed canvas, which has been scoured and bleached (to remove cottonseed oils and seeds) or raw canvas, will perform better to stain painting techniques if the cloth is pre-washed in a water-diluted solution of MM3 Surface Tension Breaker. A diluted MM3 Surface Tension Breaker solution can also be brushed straight onto the stretched canvas and allowed to dry.
