Select which kind of sand you want to use to create your textured paint. Fine sand will give your walls slight texture, while coarse sand will give your walls more texture.
Fill the bucket 2/3 full of the exterior latex paint.
Add 1 cup of sand at a time to the paint. Use the paint mixer to mix it into the paint. Add more sand and keep mixing the paint until you get the desired consistency. The final consistency of the textured paint should be wet enough to brush onto the walls of your home with a roller.
