How should I prepare surfaces before painting with Apple Barrel Pouring Medium?

Apple Barrel Pouring Medium does not require a lot of surface prep.  The main concern is to have the surface thoroughly cleaned well prior to painting.  You may also find it easier to create a marbled effect over a surface that has been basecoated with Apple Barrel Acrylic Paint.

• Wood – If desired, sand smooth any rough areas prior to painting.
• Terra Cotta – Wipe to remove dust.  If the terra cotta has been previously used, be sure to thoroughly clean in warm soapy water to remove all dirt deposits and allow to dry completely.   If the terra cotta flower pot will be used with a live plant, seal interior prior to planting so water does not seep through possibly blistering exterior paint.  
• Metal and Tinware– Metal that has been enameled or sealed should be washed in warm soapy water, dried and then wiped with rubbing alcohol to remove remaining grease or soap residue.
• Canvas – No prep required prior to painting on canvas.
• Papier Mache – Wipe over surface with dry paper towel to remove dust.
• Glass and Ceramics – Wash surface well in warm soapy water, rinse and allow to dry thoroughly.  Wipe over surface with rubbing alcohol to remove remaining soap or grease residue.
• Bisque or Unglazed Ceramics – Wipe to remove dust or loose dirt.
