Papa Nexler MOST + is designed to perform single-layer waterproofing on concrete bridge structures: road and rail, primarily on platform slabs, followed by mechanical vehicle movement. Nexler roofing insulation can be laid on other traffic constructions, including underground constructions.

Application

• For single-layer waterproofing on concrete bridge structures.
• Nexler roofing insulation can also be laid on other communication structures, including underground structures.

Laying method

• Apply by welding after impregnating the substrate with a specialized primer.

Conditions of use

• Insulation work should be carried out in good weather, with an ambient temperature above +5 C;
• Do not carry out insulation work during strong winds and precipitation in atmospheric conditions;
• The insulation is laid on a sufficiently strong, dry, clean, level and smooth surface;
• Insulation from Nexler roofing felt should be made by gluing one layer of roofing felt on a cement concrete base with a prime primer;
• Rolls of roofing felt should be protected from getting wet, direct sunlight and sources of heat;
• Transport and store roofing paper in an upright position in one layer; secured against falling over and mechanical damage.
