Slows drying to give more working time of color for extended blending and manipulation. A ratio of 1:1 color to additive volume doubles the drying time. Maintains color viscosity and has no effect on the finished color when dry. Review: Works well!! - This slow drying medium is definitely effective and doesn’t require much to do the job. The small bottle lasts a long time and keeps paint from drying too fast. If initially liquidy the paint will change consistency as it’s exposed to air. It’ll become thicker, but still perfectly useable. 10/10 Review: Love this product - Great product for painting. Does exactly what it is suppose to do. Extends the drying time and makes a really lovely painting when you blend with it. Smooth on the brush, My only complaint is that the bottle is tough to squeeze. I would still purchase this product repeatedly. ## Features - Slows the drying time of acrylic color to give more working time for extended blending and manipulation - A ratio of 1:1 color to additive volume doubles the drying time - Maintains color viscosity and has no effect on the finished color when dry - Maintains no color shift from wet to dry when used with artists' acrylic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003T0YXYM | | Age Range Description | Adult | | Best Sellers Rank | #13,507 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #336 in Art Paints | | Brand | Winsor & Newton | | Brand Name | Winsor & Newton | | Color | Slow Drying Medium | | Container Type | Tube | | Coverage | Medium | | Customer Reviews | 4.7 out of 5 stars 1,058 Reviews | | Finish Type | Matte or Satin | | Global Trade Identification Number | 00884955001813 | | Item Form | Liquid | | Item Type Name | Winsor & Newton Professional Acrylic Slow Drying Medium, 250ml | | Item Volume | 250 Milliliters | | Item Weight | 0.28 Kilograms | | Manufacturer | ColArt Americas | | Model Name | Winsor & Newton Professional Acrylic Slow Drying Medium, 250ml | | Model Number | 3040932 | | Paint Type | Acrylic | | Part Number | 3040932 | | Size | 8.45 Fl Oz (Pack of 1) | | Special Feature | Slow Drying | | Special Features | Slow Drying | | Specific Uses For Product | canvas | | Surface Recommendation | Acrylic | | UPC | 884955001813 | | Unit Count | 8.45 Fluid Ounces | ## Product Details - **Brand:** Winsor & Newton - **Color:** Slow Drying Medium - **Finish Type:** Matte or Satin - **Item Volume:** 250 Milliliters - **Paint Type:** Acrylic - **Size:** 8.45 Fl Oz (Pack of 1) - **Special Feature:** Slow Drying - **Specific Uses For Product:** canvas - **Surface Recommendation:** Acrylic - **Unit Count:** 8.45 Fluid Ounces ## Images ![Professional Acrylic Medium, Slow Drying, 250ml (8.5-oz) - Image 1](https://m.media-amazon.com/images/I/71hEaf3XpQL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well!! *by R***R on April 23, 2023* This slow drying medium is definitely effective and doesn’t require much to do the job.
