Open-ended wood cells not sealed are likely to cause which issue in stained wood?

• A. Dark spots on stained wood
• B. Even color distribution
• C. Glossy finish
• D. Uniform grain

Answer: (A)

Open pores act like tiny sponges, so when wood cells are open and not sealed, the stain is absorbed unevenly. Some areas soak up more pigment than others, creating blotches—dark spots where the pores are most exposed. Sealing the wood or using a pre-stain conditioner helps equalize absorption and produces a more even color. A glossy finish comes from the topcoat, and uniform grain or overall color is more about wood type and milling than whether pores were sealed, so those outcomes aren’t the direct result of unsealed open-ended cells.
