## Description

A fluid that slows the drying time of acrylic paints and mediums by up to 40%. An absolutely essential additive if working in drier climates. Mix into the paint when on the palette to slow the skinning-over of paint and increase blending time. Should not add more than 25% as there is no binder and it can weaken the stability of the paint film when too much is added.

## Features

- A binder-free fluid with slow drying agents
- Increases ‘open‘ (working) time of acrylic paint
- Reduces paint skinning-over on palette
- Increases blending time, making blending of colors and detail brushwork easier

## Questions & Answers

**Q: i am not using an airbrush, but i need thin non-glossy glazes. would this work? thanks**
A: I know this is late,but I use Golden Airbrush medium to thin my paint for glazes.

**Q: Can this be used to thin (Vallejo) Acrylic-Polyurethane liquid primers (for miniatures)?**
A: I don't know. From what I hear you can use it to thin just about any acrylic-based paint. However, not sure how the polyurethane in the primer would react. I think a good test would be to mix it up and see. Start with the primer in a mixing cup (couple of drops), then add the airbrush medium a drop at a time (mixing each time and checking consistency, clumping, etc). If you get a good mix without clumps and about the consistency of low-fat milk, you should be able to apply through an airbrush. I would recommend testing on a test plate to see how it adheres before using it on your finish piece! Good Luck.

**Q: *For those who used both products*, please: Is this different different from pouring effect medium?**
A: The "Pouring effect medium" has more control, but the flow aid is mainly used for completely liquefying the paint, while keeping consistent color I have used this with airbrush art, and mixing effects with other Liquitex/other brand acrylic mediums.  On a more casual, non-air-brush point of view:  This can totally thin paint, but there is other stuff out there, that will suit your needs.  BONUS**  This works wonders if you 1. need a shorter drying time OR 2. Have lesser quality acrylic in old tubes and want to turn out well.

**Q: I have createx airbrush paint for nail art.  The problem is it air comes out but no paint.  Ive cleaned the needle still no paint spray.**
A: The number of reasons why your air brush is not working is huge.  I would try and verify that you can shoot water through the air brush, if you can, the you can fiddle with air pressure, or thin the paint, or clean the brush, or go to a larger tip size.
