For sealing roof joints, holes and cracks, for sealing joints between drains and roof elements, for easy and quick repair of roof leaks, for bonding and repairing roofs without heating, for emergency repairs even when it is raining, for connection joints in construction.

Usage
The walls of the joint must be clean, dry and free of grease. The surfaces may be damp – in this case we recommend testing the adhesion strength beforehand. The temperature when applying the silicone should be between +5° C and +30°C, but it is recommended that the silicone be applied at room temperature. When sealing large surfaces we recommend applying the sealant in strips or dots to accelerate the evaporation of the solvent.

Cut off the tip of the can and screw on the nozzle. The tip of the nozzle should be cut at an angle (about 45 degrees) depending on the width of the joint. Place the can in the silicone gun. Apply the material thickly into the joint. Special
Attention should be paid to adhesion to the joint edges. Smooth the sealant with a damp trowel or other suitable tool. Tools and soiled surfaces can be cleaned with white spirit before the material has fully cured.
but. Joint dimensions: minimum width 5 mm; maximum width 30 mm; minimum depth 2 mm; recommended ratio for joints with a width of 6-12 mm, filling depth 6 mm.
