        Operating Rules

        • Working surfaces need careful preparation. This stage is important, it determines the success of the final result. The surfaces on which glue composition will be applied, it is necessary to thoroughly clean from pollution and handle sandpaper: roughness will provide higher adhesion.

        Also the workfield should be degreased. To do this, you can use acetone. This preparation can be considered completed.

          • In most cases, cold welding sticks to the hands, which complicates the process of creating a smooth and beautiful seam. Eliminate this problem by wetting hands. It will not affect the operational characteristics, but the mass will be more obedient.
          • When working with two-component materials, it is necessary to mix glue and hardener. Plasticine welding is mixed until a homogeneous mass is obtained, in a liquid version, two components are connected to each other. It is necessary to do this before applying, a job is given for about three minutes. During mixing, the mass can highlight heat.
          • Prepared material is applied to the workspace, in the location of the future seam. Adhesive mass is distributed over the surface, pressed and smoothed. It is necessary to achieve maximum tightness.

          • When the planes are connected, they must be fixed using the clamps. In this case, the seam will be much stronger and more reliable. Special harnesses are used to work with pipes. When gluing the floor covering applied roller rollers.
          • The full time of frozen can be varied, depending on the manufacturer, the type of adhesive composition and the thickness of the seam.
          • After the complete pouring of the glue, you can engage in putty, painting and other repair work.

          You can not violate the instructions, it can lead to a reduction in the life and decrease in the characteristics.
