When to Use a Primer or Sealer
While it is always wise to use a primer or sealer to achieve the highest quality paint job, it is especially important in the following circumstances:
• when painting new wood or another surface that has never been painted before
• when painting chalky surfaces severely weathered paint
• when repainting a surface that is uneven or badly deteriorated (Note: Weathered wood should be thoroughly sanded before painting)
• when painting a surface that has been stripped or is worn down to the original surface material
