This brilliant additive increases the flow of acrylic colours by breaking down the surface tension of the water. It's ideal for the application of areas of flat and even colour without changing colour strength. It's also effective for hard edge painting techniques, staining and water colour techniques.
Flow Improver maintains the stability of the colour and slightly slows drying, so colours will remain usable slightly longer when mixed with this medium. If you want to dilute your colour significantly, we recommend using Flow Improver with your water, as this preserves the integrity of the paint film, ensuring the pigment remains sufficiently bound.
Under-bound colour can appear blotchy, may become brittle or not adhere to the canvas well, all issues which are avoided if you use Flow Improver. This additive maintains no colour shift from wet to dry when used with Winsor & Newton Artists' Acrylic.
