Posca art work cracking?????????

Hi guys, Some help please. Recently shaped a 5’5’’ kind of bar recently and just done a bit of posca work on it. No prob untill i sealed with acrylic sealant and some of the colours have now cracked? Any ideas how to prevent this in the future as planing on more artwork.

Cheers muel

Hello Muel,

 

Either seal with polyester (hotcoat or gloss) resin or epoxy resin. Sand the board 120 grit and 220 on the parts where posca goes to prevent bleeding.

 

Ahoy
