Also suitable for section or panel repair, especially for small surfaces, apply thin coats.If you want a thick layer: first apply a layer at a distance of 30-35 cm and then apply another layer crosswise at a distance of 20 cmAll spray bases have a special nozzle that sprays flat vertically, comparable to that of a paint gun. For foundations with high viscosity: shake the container well before using for the first time.
