Use the correct nap length when applying texture paint. The nap is the fuzzy covering on the cardboard center of the roller. The longer the nap, the more paint it will hold. For textured paint, use a 1/2 or 3/4-inch roller. For light to medium texture a 1/2-inch roller can be used, or simply choose the 3/4-inch roller for all projects. Using a roller with a low amount of nap will not properly hold enough texture paint to cover a surface smoothly.
When rolling on textured paint, your roller will feel heavier. Using a small mini roller creates a less labor-intensive project because the roller will feel lighter, which is important when painting walls and ceilings. Standard mini rollers are about 3 inches in length. The rollers come with fabric covers that will hold textured paint; do not use the foam rollers occasionally sold with the roller system. The covers can be used for several projects and rinsed out after each use.
Pour the textured paint into a paint bucket. Always stir the paint before use and during the application process. The sediment in the textured paint tends to settle to the bottom if not stirred about every 15 minutes. Roll the paint on using a random roller pattern. Do not roll in horizontal or vertical sections as you will see roller lines. Instead roll the texture paint on overlapping areas during the process.
Texture Paint Tips
If you see too many lines when applying your textured paint, apply a second coat of paint using a damp sea sponge. Dip the sponge into the paint, and dab it onto the area randomly to cover any paint roller marks. If you want heavier texture, add more layers of the paint. Extra grit and texture may be added to the product by adding sand or other materials.
