Plastic Sanding Block

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.

Do not add more hardener, because after the base has cured, the remaining hardener will react with subsequent layers, which will be applied to the surface and cause defects. For the product to work properly, please follow the proportions given by the manufacturer.
