Poor Sheen Uniformity

May 08, 2017
This refers to areas of uneven gloss – shiny or dull spots – that may occur on a freshly painted surface.


  • An uneven spread rate
  • Failure to properly prime a porous surface, or a surface with varying degrees of porosity
  • Poor application resulting in lapping


New substrates should be primed or sealed before applying a topcoat, as this will ensure a uniformly porous surface. 

If a primer or sealer is not used, you may need to apply a second coat of paint. This additional coat will frequently even out sheen irregularities. Take care to apply the paint from wet to dry to prevent lapping.
