to make the surface of a wall or a ceiling smooth by spreading a new layer of plaster (= a substance that becomes hard as it dries) on it

Today we are going to replaster the whole house: floors, ceilings, and walls. 今天，我们会全屋重刷灰浆：地面、天花板和墙。

Every year, the whole community works together to replaster the mosque. 每年，整个社区会一起给清真寺重刷灰浆。
