Its binder-free formula prevents premature skinning on palettes and enhances blending capabilities without diluting pigment strength. Ideal for artists working in dry climates, it also offers a fade-resistant finish to preserve the vibrancy of your artwork. ## 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: Great extender and retarder. - If you use acrylic paint, this is a great extender without ‘watering down’ the pigment. It slows drying time for better workability and blend ability too. Review: Liquitex rocks - Great as always ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004M559I2 | | Age Range Description | all ages | | Best Sellers Rank | #925 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #45 in Art Paints | | Brand | Liquitex | | Brand Name | Liquitex | | Color | Slow-Dri Fluid Additive | | Container Type | Bottle | | Coverage | Medium | | Customer Reviews | 4.7 out of 5 stars 1,372 Reviews | | Finish Type | Gloss | | Global Trade Identification Number | 00094376926088 | | Item Form | Liquid | | Item Type Name | Effects Medium | | Item Volume | 4 Fluid Ounces | | Item Weight | 0.05 Kilograms | | Manufacturer | ColArt Americas | | Model Name | Professional | | Model Number | 126704 | | Paint Type | Acrylic | | Part Number | 126704 | | Size | 4 Fl Oz (Pack of 1) | | Special Feature | Fade Resistant | | Special Features | Fade Resistant | | Specific Uses For Product | Art Painting | | Surface Recommendation | Paper | | UPC | 094376926088 | | Unit Count | 4.0 Fluid Ounces | ## Product Details - **Brand:** Liquitex - **Color:** Slow-Dri Fluid Additive - **Finish Type:** Gloss - **Item Volume:** 4 Fluid Ounces - **Paint Type:** Acrylic - **Size:** 4 Fl Oz (Pack of 1) - **Special Feature:** Fade Resistant - **Specific Uses For Product:** Art Painting - **Surface Recommendation:** Paper - **Unit Count:** 118 Mililitro ## Images ![Professional Effects Medium, 118ml (4-oz), Slow-Dri Fluid Retarder - Image 1](https://m.media-amazon.com/images/I/71uQyVhyP8L.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great extender and retarder. *by S***E on August 14, 2025* If you use acrylic paint, this is a great extender without ‘watering down’ the pigment. It slows drying time for better workability and blend ability too. ### ⭐⭐⭐⭐⭐ Liquitex rocks *by P***W on November 23, 2025* Great as always ### ⭐⭐⭐⭐⭐ Works great *by R***I on October 25, 2024* The bottle says not to mix this alongside other additives, so most of the time I only add this to my paints for use with an airbrush and it can both thin the mediums while preventing them from drying as fast. In particular, it helps me prevent dry tip buildup while using primer. I’ve used this with dollar craft paint, dedicated airbrush paint, acrylic ink, and water based primers. ## Frequently Bought Together - Liquitex Professional Effects Medium, 118ml (4-oz), Slow-Dri Fluid Retarder - Liquitex Professional Gesso Surface Prep Medium, 237ml (8.0 oz), Clear - Liquitex BASICS Acrylic Paint, 250ml (8.5-oz) Tube, Titanium White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/4542532-professional-effects-medium-118ml-4-oz-slow-dri-fluid-retarder](https://www.desertcart.pe/products/4542532-professional-effects-medium-118ml-4-oz-slow-dri-fluid-retarder) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-06-17*
