Do You Need to Sand Wood Before Paintingを徹底追究! 読者が気になる トピックの裏側を分かりやすく展開します。

Ah, the magical world of primers! Some primers claim to be “self-leveling” or “adhesion-promoting.” They’re like the superheroes of paint prep. But even superheroes have limits.

Think of it like a seatbelt. You don’t always need it, but when you do, you’re glad you buckled up. Sanding is your painting seatbelt.
