Liquitex Slow Dri-Gel Retarder Additive 237ml

Slow drying time by 40%, without affecting color opacity, so you can work it for longer.

Key Features:

• Extends the open time of your gel color/medium by 40% so it is blendable and workable for longer
• Maintains the same level of transparency
• Thickens and increases viscosity
• Retains brush/knife marks
• Ideal for dry and hot climates

How to Use:

• Start by adding up to 25% of Slow-dri to your color/medium with a knife
• Mix in slowly and thoroughly, and use
• If you're working over a long period of time, mix into color on the palette to keep it fresh and skin-free for longer
• 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 the acrylic film to break down, leaving it sticky and prone to shrinkage
• Do not use with any non-acrylic media
