Liquitex Flow Aid breaks water tension to improve flow, absorbency and blending of any water based paints, ink or dye to minimize brush strokes. Great for staining effects on raw canvas. Breaks water tension to improve flow and lower viscosity Gives a smooth finish with less brush strokes due to reduced surface friction Increases transparency and makes color more absorbent and blendable   How to use   First dilute your concentrated Flow Aid with water - 1 part Flow Aid to 20 parts water - distilled water will give the best results. Use 1 part Flow Aid to 10 parts water if you want a more concentrated effect Add up to 25% of diluted Flow Aid to your color/medium and stir slowly to avoid foaming. If it does foam, leave it to sit while the foam disappears If applying to an absorbent surface, your color/medium will sink in like a stain or dye; if using on a non-absorbent surface your color/medium will be more fluid and take longer to dry Fully intermixable with all Liquitex products Do not use Flow Aid undiluted as it results in poor acrylic adhesion, cracking, tackiness and water sensitivity As this is an additive – with no acrylic binders - do not add more than 25% to your color/medium and do not mix with other additives. This can cause excessive shrinkage, cracking and the acrylic film to break down Do not shake or stir too vigorously as foam will form Don't use for marbling as it breaks the surface tension of the water Do not use with any non-acrylic media
