Jo Sonja's Retarder Medium 250ml

Slow down drying for easier blending. Is an additive used to extend the “open” or drying time of Jo Sonja’s Colours and Mediums. Acrylic paints dry rapidly in conditions of low humidity and/or high temperature. Both air conditioning and winter heating reduce the levels of humidity in a room causing acrylic paints to dry faster.

• Slows the drying time of acrylics
• Great for blending and wet-in-wet work
• Size: 250ml

Perfect for: Blending, shading and painting in hot, dry conditions.

Directions: Add Retarder to your paint by dipping your brush into it as you paint, or apply over the entire surface area for wet-on-wet techniques. Blend with a mop brush to ensure an even coat without puddles. Retarder may be mixed directly into your paints. When used for antiquing, dilute your colours with Retarder instead of water for a longer open time. Earth colours are popular for antiquing. Important: Paints containing Retarder may appear to be dry but can be reactivated. They can take up to 5 days to cure unless force dried with warm air. When proceeding with additional steps or varnishing a piece, care should be taken that all Retarder is completely dry.

NOTE: CRACKLE MEDIUM WILL NOT ADHERE TO A SURFACE CONTAINING ANY TRACES OF UNCURED RETARDER THAT IS NOT COMPLETELY DRY.
