HOW TO REMEDY

The only way to eliminate the problem of a lack of adhesion to the painted surface is to remove the dried film down to the raw substrate with 80-grit sandpaper and apply a new coat of paint starting from the first coat.
Alternatively, in less critical instances, one may remove the defect...

NOTE: air bubbles trapped in the base coat may be due to very small holes in the surface (see PIN HOLES). During, they open to form tiny hollow craters which are difficult to visibly level in subsequent coats.

HOW TO REMEDY

The only way to eliminate the problem of blowing on the painted surface is to remove the dry film down to the raw surface with 80-grit sandpaper and apply a new cycle of paint starting from the first coat, as it is practically impossible to solve the problem using sandpaper and/or additional coats...

CAUSE

This happens on multi-layer, marine shutters with phenolic resin. From the time of production, phenolic resins contain a variable percentage of caustic soda as a stabilizer (NaOH). Due to their permeability in water, water-based coatings favour solubilization and therefore migration of the caustic soda...

HOW TO REMEDY

The only way to eliminate the problem of chips on the painted surface is to scour the dry film down to the raw surface with 80-grit sandpaper and apply a new cycle of paint starting from the first coat.
In all cases, identify and remove the cause of the problem before repairing.
A list...

In most cases, if coverage is the only problem, it is only necessary to sand the surface and apply additional coats until the desired effect is achieved, compatible with application requirements described on the Technical Data Sheet.
A list of possible causes of coverage problems is...
