Intro
Texture adds interest, variety, and style to walls and ceilings. A soft spray-on texture that's used exclusively on ceilings is sometimes called "popcorn" or "cottage cheese." Contractors love it because it's faster (and therefore less expensive) than a ceiling that's carefully sanded. Although you can skip the sanding, don't get careless about filling seams and covering the fastener heads. Such defects will show through the texture, especially under critical lighting situations.
To shoot on popcorn texture, you'll need a compressor and must buy or rent a hopper. Bags of texture are available in several sizes of granules. As a rule of thumb, avoid bulky textures in a small room; the texture can become too dominant, making the room seem even smaller.
You can spray thinned joint compound through an airless spray rig to create a range of textures on walls and ceilings. Not all applications require fancy equipment. Brooms, sponges, toothed trowels, flat trowels, and other tools yield an unlimited variety of textures. Experiment on scrap pieces of drywall or on closet ceilings to perfect your technique.
