Jo Sonja’s Retarder Mediumis 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.

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.
