This is a fairly simple test - spend a spatula at the place of attachment sheet if the blade glides smoothly, then everything is in order. If trowel clings to the protruding screw heads and nip them.

• If the screws are screwed too deep (cap is recessed to a depth greater than half the thickness of the sheet) remove the screw and at a distance of 50 mm from the new screw (in the former hole not tighten screw recommended).
• If the surface of the sheet noticeable local defects - scratches, dents, and close them before applying putty common layer.
• If the defect is deep, terminations have to be carried out in several stages, each time waiting for the previous layer to dry.

Application of soil

• A common mistake when carrying out this type of work - lack of treatment of joints. The fact is that when drying putty more compressed, so the site level, it would seem, depression may form surface.
• So do not feel sorry for putty, possible excess can be easily removed by grinding.
• If desired multiple layers of putty, to spray the next can begin only after the previous dry well.
