Finish TradesQuestion 250 of 700
To reduce ceiling sag when a water-based spray texture will be applied, code and industry guidance generally require which gypsum board for ceilings framed 16 inches on center?
a.1/4-inch board is fine
b.3/8-inch board is required
c.1/2-inch sag-resistant board, or 5/8-inch board
d.No board thickness matters for texture
Explanation
For 16-inch on-center ceiling framing that will get a water-based texture, standard 1/2-inch board can sag, so either 1/2-inch sag-resistant (interior ceiling) board or 5/8-inch board is used. Thin 1/4 or 3/8 boards sag badly, and thickness definitely matters when a wet texture adds weight.
