Is Primer Necessary For Painting Interior Walls?



Using primer when repainting interior walls depends on a few factors:


  • Surface Condition: If the walls have significant stains, marks, or discoloration, primer can help cover them up and provide a clean base for the new paint.
  • Color Change: If you're changing the color of the walls dramatically, using a primer can help ensure that the new color appears true and vibrant, especially if the current color is much darker than the new one.
  • New Drywall or Plaster: For newly constructed walls or those that have been patched or repaired, primer helps to seal the surface and provide better adhesion for the paint.
  • High Gloss or Oil-Based Paints: If the current paint is high gloss or oil-based, primer can provide a suitable surface for the new paint to adhere to, as these surfaces can be difficult to cover with water-based paint.
  • Mold or Mildew: If there's a history of mold or mildew on the walls, using a primer designed to prevent their growth can be beneficial before applying new paint.


If none of these factors apply and the existing paint is in good condition, you may be able to skip the primer and simply apply the new paint directly. However, using a primer is generally a good practice as it can enhance the durability and longevity of the new paint job.
