We do not recommend using universal thinners. The use of a thinner with an unknown composition may result in loss of adhesion, lack of proper flow of paint and varnish defects.

We recommend to always sand the surface between applying two different products to ensure uniform surface roughness and adhesion of subsequent layers. The sanded surface should also be cleaned and degreased.

Possible causes

• Wrong surface preparation,
• Skipping the primer in the system application process,
• Use of universal thinners or replacements ,
• Paint incompatibility.

How to prevent

• Correct surface preparation (grinding, clearing, degreasing),
• Use primers which improve adhesion of paints,
• Use thinners which are dedicated to each paints,
• Use of paints which are compatible to each other.

How to remove

• Grind, clean and paint again.
