Description:
Unwanted textured finish in the paint film produced in the “roller” process. 

Possible causes:

1. The roller is not in apt conditions for its use.
2. The technique used in the application with roller is not the most adequate. 

Solution:

• Employ rollers of synthetic fiber (nylon or polyester) to apply water base paints.
• Employ roller of natural fiber to apply solvent base paints.
• Check the roller is in a good condition in thickness and uniformity before using it in the application of the paint.
• In the application of water base paints, damp previously the roller with water and then shake it to eliminate the excess of water.
• Make the “conditioning” of the roller, by leaving it impregnated with the paint five minutes before the use.
• Do not let the paint to dry in the roller after the use or when you are going to store the roller.
• Before retouching, smooth by sanding the areas that already have the problem of roller marks
