Textured paints are available in either flat-finish latex or alkyd formulations. Latex versions are used on bare drywall ceilings because they can be used without a primer and they help to camouflage the seams between sheets of drywall.
If you’re after a finish that looks like stucco, or if you want an effective cover-up for flawed surfaces, textured-surface paint will do the job. Some varieties come premixed with sand like particles suspended in the paint. Because of their grittiness, these paints are usually used on ceilings. With other varieties, you must add the particles and stir thoroughly. Another form of textured paint has no granules. Thick and smooth, it’s applied to the surface and then textured with special tools.
