Uneven colour (exterior stains)

 

Uneven colour (exterior stains)

Causes

  1. Due to their porosity, softwoods such as pine absorb stain unevenly.
  2. Uneven sanding.
  3. Uneven spreading.

Solutions

  1. Sand bare wood surface. If you have to apply a water-based stain, use water to even out the wood cellular structure and apply the stain according to the spreading methods recommended in this course.
  2. Using a sanding block or an electric finishing sander, sand the surface evenly with a 180 abrasive paper.
  3. Spread the stain evenly with a wet lint-free cloth properly wrung out. Avoid excessive scrubbing.
