After thousands of gallons of MUD and paint, I note PC gives you some valuable suggestions.





A few more details might be helpful to us. IE: Type of texture; Define Touch Up (the texture or the paint).





Certainly there are aerosol Popcorn touchups available. Knockdown might be a bit more challenging for a DIY. Pebble textures, or textures such as those in drop celing tiles would take some effort as well.





Knowing the type of texture would help us answer more clearly; rather than assuming.
