Bleeding is when plasticizers in the sealants bleeds through the paints or coatings and creates a sticky surface(as shown in the right picture).

Bleeding
The coating becomes sticky, which stickes the waste in air. Then the joints turn dark.
The bleeding-preventing type sealants are called Non-Bleed or NB Sealants.

Bleeding contamination and adhesion of paints/coatings are not quite tightly related. Bleeding contamination is caused by incompatibility of raw materials. Cracking is caused by a difference in followability between sealant and paint/coatings. We believe that with bleeding is very avoidable; cracking, however, is more difficult to avoid.
