Cissing is a visible coating defect that occurs due to an improper paint application on a metal surface intended to prevent corrosion. It is characterized by the surface breakage of a wet paint film, leading to the exposure of the base metal substrate.

What causes Cissing in paint?

This is caused by painting over contaminated surfaces such as wax, oil or polish. The paint cannot adhere to the surface and draws away leaving unpainted areas. Allow the surface to dry and then rub down using ‘wet and dry’ abrasive paper and a solution of warm water and detergent.

Why is my spray paint dimpling?

They are a direct result of the presence of minute levels of contaminants on the surface.

What causes paint to crack? Insufficient surface prep is the main culprit behind crack attacks. Over-thinning your paint or applying it too thinly can also cause it to split.
