Installation:
Temporary damming boards, forms, sleeves and/or duct tapes can be used to prevent leakage of the sealant material during the installation and curing. These temporary devices are removed after the material has been cured sufficiently (2-3 hours).
Preparation of the Sealant Material with Flammadur® E983
The cementious sealant material is prepared by mixing water thoroughly with the sealant powder E983 at a weight ratio of approximately 100 parts of E983 to 35 to 40 parts of water. The mixture can be adjusted from a trowelable to a pumpable consistency by varying the amounts of E983 powder and water. Water and/or E983 powder can always be added to an existing mixture during its pot life of 60 to 75 minutes.
The sealant material can be installed readily by qualified workers with tools and methods which are commonly used for construction work of this type.
