Skim coat
A skim coat is a thin layer of joint compound spread over a wall or ceiling to smooth and unify the surface.
Why it matters
It helps hide patches, texture differences, and minor flaws.
Where people get this wrong
Skim coat is not spackle. It is a broader surface treatment. Skim coat requires sanding and careful priming.
Real-world example
A wall has old texture and patch marks from repairs. A skim coat makes the wall look like it was never touched.
Where this hits your build
This comes up during the finish phase. Lighting, angles, and personal expectations collide here. What looks fine at noon can look rough at dusk.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
