Gel Retarder Delays Drying Time of Acrylics

Approximate Coverage: 1 oz = 3 square feet 1 ml e = 94 square cm.
Gel Retarder extends the drying time of the Jo Sonja’s Artists’ Colours. It allows an extended working or “open” time for blending and a thicker application of colour can be used in painting techniques.
Gel Retarder may be used in various ways.
Practise techniques using this medium before committing to a project.
Directions:

  • As a painting medium, moisten the brush with Gel Retarder and blend well with colour. If paint drags during painting, refresh by picking up additional Gel Retarder in the brush and repeat palette blending.
  • Apply a thin coat of Gel Retarder directly to the surface for an extended working time.
  • Retarder Medium can be used to thin the Gel Retarder and decrease the “open time” as needed for your area. Begin with 1 part Gel Retarder to 1 part paint.
  • Gel Retarder may be mixed directly into palette colours beginning with an approximate ration of 1 part Gel Retarder to 3 parts paint.
  • For antiquing, thin colour with Gel Retarder. Ratio is determined by strength of colour desired. Begin with 2 parts paint to 1 part Gel Retarder. Apply over the painted surface and wipe to create desired effect. Use Gel Retarder on a cloth to remove excess.
  • When using Gel Retarder, drying time is greatly extended. Surface may feel dry and still be holding moisture. A hair dryer can be used to speed surface drying. An extended dry and curetime should be allowed and varies due to humidity and climatic conditions.
  • A coat of Flow Medium, Magic Mix or Clear Glaze Medium is recommended prior to application of varnish. Any “seizing” or curdling of the product indicates the presence of uncured Gel Retarder. Immediately stop application and dry completely before proceeding.
    Clean up with mild soap and cool water.
    Note: Gel Retarder is not recommended for use in brushes after cleaning.
