Application method:
The surfaces to be sealed must be clean, dry and free of loose rust, scale, dust, talc and dirt. All oil, grease, silicone or other contaminates should be first removed with a suitable solvent/cleaner.
For older roofs use a stiff brush to remove all loose granules and surface elements.
Porous surfaces should be primed with a common asphalt based primer and allowed to dry before Xunda-T 700 is applied.
Install Xunda-T 700 by gradually peeling away the plastic release liner while rubbing the Xunda-T 700 to the surface.
Hint: prevent bubbles under the product by using your hand to squeegee out air by wiping your hand towards the roll as you set the tape to the surface.
Overlap seams or sealing are of application by 3 inches.
