Bleeding
A red or yellow discoloration in the topcoat color.
Cause:
Solvent in the new topcoat dissolves soluble dyes or pigments in the original finish, allowing them to seep into and discolour the new topcoat.
Repair:
- Allow colour to cure, isolate with two component undercoat(s) and refinish.
- Or, remove original paint film and refinish.
Prevention:
Isolate suspected bleeding finish by applying a two component surfacer and/or sealer. Allow to cure following product recommendations, and then apply desired topcoat.
