Product application: ASO®-DB-Standard at the transition between wall and floor as well as interface joints to the prepared area without voids or folds. Butt joints must be overlapped by 5 to 10 cm. Ensure that a sealed connection to the surrounding waterproof membrane is produced.
Properties: • Elastomeric coating • Water impermeable • Elastic • UV stabilized • Weatherproof • Alkali resistant
1. Coat both sides of the joint to be bridged with the waterproof membrane to a width of at least 2 cm wider than the waterproof tape, e.g. with a 4 – 6 mm notched trowel. 2. Then thoroughly work the waterproof tape, without voids or folds, into the waterproof membrane using a steel trowel or pressure roller. Ensure that, as far as possible, a full bed and wetting out is achieved. Bonding must be performed in such as way as to exclude the migration of water behind the waterproof tape. 3. The waterproof tape is to be worked into movement joints as a loop. 4. Overlap butt joints within waterproof tape sections or at interfaces with all waterproof tape pre-formed pieces and corners by a minimum of 5 to 10 cm and bond with the waterproof membrane, without voids or folds. Overcoat with the chosen waterproof membrane. Application: All usual substrates, which are correctly prepared and suitable for use with the installation of waterproof membranes or tiled finishes in the appropriate wet duty classes (ZDB data sheet ‘bonded waterproof membranes’). Fine, non-penetrative cracks on the surface of < 0.1 mm are acceptable.
