Wall and ceiling texturing produces an aesthetic appeal to the room, as well as covers up any mistakes made during the installation and sealing of the drywall. Though you can apply many different types of texture, stipple texturing is popular, as it does not require any special tools such as air compressors and hoppers. Vary the degree of stippling through the nap size of the roller you use to apply the compound mixture.
Pour roughly a gallon of premixed drywall compound into a 5-gallon bucket. Pour water into the compound 1/2 pint at a time and mix with a stirring stick. Apply more water or compound as needed, to acquire a mixture roughly the thickness of latex paint.
Pour the mixture into a paint tray. Completely cover a paint roller (1/4- to 1-inch nap) and apply it to an area of wall that is generally not seen, such as the interior of a built-in closet. First roll up and down, then from side to side over the same area. Wait for the area to dry for 10 minutes, or until the mixture has a dull wet sheen. Roll over the area without any more mixture on the roller, to produce a ridged grain pattern.
Look at the size of the stipple. If it is too big, use a smaller nap roller, or if it is too small, use a larger nap roller. After choosing the correct size roller, repeat the installation process on all parts of the walls/ceiling in the room.
Wait for the stipple texture to dry completely (usually 24 hours) before applying primer and paint.
