## Overview

Liquitex Professional Effects Medium is a binder-free slow-dri fluid additive that extends acrylic paint drying time by up to 40%, reduces skinning on palettes, and enhances blending capabilities. Ideal for artists working in dry climates or seeking more control over paint texture and detail, it maintains a fade-resistant glossy finish without compromising paint stability when used within recommended ratios.

## 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.

Review: Works Well and Easy to Use - Pretty straight forward to use. Pour equal parts acrylic paint and this project and it makes it pretty easy to paint on fabric. It also requires no heat setting. For drying, I just let it sit over night, undisturbed.
Review: OUTSTANDING!! - This stuff is fantastic. Works like a charm to thin your paint and extend coverage. Just be sure to mix it exactly as recommended because it is potent. Excellent value and if used properly, it will last a very long time.

## Features

- A binder-free fluid with slow drying agents
- Increases ‘open‘ (working) time of acrylic paint

## 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.
