    Limitations

    It must not be used in totally confined spaces where sealant cannot cure 
    due to lack of atmospheric moisture. 
    Multi-Seal can be applied to a variety of substrates directly. If not sure, we recommend a preliminary 
    compatibility test.

    Surface Preparation

    ● Following cleaning procedure and materials are recommended
    ● Glass Degrease with alcohol or MEK
    ● Aluminium, light alloys and stainless steel Degrease with alcohol or MEK
    ● Other Metals Lightly abrade then degrease as above
    ● Wood Lightly abrade surface then remove dust
    ● Plastics Degrease using an agent recommended by plastics manufacturer
    ● Concrete and other alkaline Surfaces Brush and remove dust

    Instruction

    1. Before the application, the tip of the cartridges is cut and a plastic cap is fixed. 
    2.The tip of the cap is cut according to the width of the surface and fixed to the 
    cartridge gun. 
    3.The sausage package is cut from one edge and fixed to a suitable gun. Then the cap 
    nut is screwed to the cylinder of the gun. 
    4.The joints should be filled at one time and without gaps during the application. 
    5.The surface of LaSeal Universal applied in the joints should be smooth ended with a dampened spatula, glazing tool, joint iron or by hand immediately.
    6. If used, the adhesive tape should be removed afterwards. 
    7.The opened packages should be consumed as quickly as possible. 
    8.The contaminated areas and used tools should be cleaned with white spirit or alcohol. It is cleaned only 
    mechanically after cured. 
    9.Joint width/depth ratio should be 2:1.

    Storage and shelf life
