Description:
Defect of the painting characterized by the absence of a completely smooth film, originated by the presence of marks of brush or roller once the paint has dried. 

Possible causes:

1. Application of additional paint, or premature re-brushing or re-rolling in areas where the paint has dried partly.
2. So rapid application or so high extension of the paint on the surface (the brush or roller does not contain sufficient paint to cover correctly the surface to work).
3. Inadequate selection in the size of roller or brush.
4. Application too thin of the paint film.
5. Application of the paint on very hot surfaces or in direct sun.
6. Too porous surface to paint.
7. Inadequate dilution of the painting.
8. The tools of application are not in good condition or are not the best quality. 

Solution:

• Let the paint dry completely, sand to smooth and retouch again.
• Wait until the paint has dried completely before retouching.
• Apply the paint using an adequate technique according to the type of paint, type of surface and area of the surface. See the section: Installation Advices.
• Follow the instructions related to number of coats to apply as well as times of drying and retouch.
• Seal or apply a primer in porous surfaces.
