Symptoms

The paint system shows local cracking, which results in loss of adhesion and   flaking.

Cause

• Internal stresses of paint system
• Deformation substrate breakdown of the substrate eg. joints breaking, splits in the timber
• Wrong paint system
• Several layers are applied which are not   compatible
• Insufficient elasticity of applied paint
• Cracking originating from substrate
• Condensation on substrate upon application

Solution

Paint layers that are not sound should be removed. After the right pretreatment, a new system should be applied. Touch up bare spots with [Onol resp. Rubbol Grund] and finish with [Rubbol SB] or [ Rubbol AZ ].
