How should I prepare surfaces before painting with FolkArt Flash Iridescent Topcoat?

FolkArt Flash Iridescent Topcoat does not require a lot of surface prep.  The main concern is to have the surface thoroughly cleaned, and basecoated with FolkArt Acrylics well, prior to applying the topcoat.    

• Wood – Sand smooth any rough areas, apply a basecoat of acrylic paint; allow to dry.  Lightly sand smooth and reapply the base color.  Allow to dry.
• 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 live plants, seal interior prior to planting so water does not seep through possibly blistering exterior paint.  Apply a basecoat of acrylic 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.  Allow to dry and then apply the desired basecoat.
• Canvas – No prep required prior to painting the basecoat on canvas.
• Rigid Plastic – Wash the surface well in warm soapy water, rinse and thoroughly dry.  Wipe over surface with rubbing alcohol prior to painting on rigid plastic to remove remaining grease or soap residue. Then apply desired basecoat color.
• Papier Mache – Wipe over surface with dry paper towel to remove dust and then basecoat. 
• 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. Paint desired basecoat of color or use directly on glass.
• Bisque or Unglazed Ceramics – Wipe to remove dust or loose dirt.  Basecoat acrylic color of choice.
