Uneven appearance (uneven gloss)

Causes

  1. Paint poorly shaken.
  2. Porous surfaces poorly sealed. Glossy paints tend to emphasize surface defaults.
  3. Uneven surface.
  4. Uneven spreading.
  5. Application of one paint coat only.
  6. Substrate affected by dew, rain or humidity during the drying time. In such conditions,
  7. solid colour coatings become flat, and transparent coatings become whitish or greyish.
  8. Temperature variation during drying process.
  9. Lap marks resulting from a failure to maintain a wet edge (exceeding product’s drying time).
  10. Touch up made on a dried painted surface.
  11. Changes of tools during application - brush vs. roller.

Solutions

  1. Clean and sand the surface, then suck up any dust. Apply a new coat of coating.
