CONSTRUCTION INSTRUCTIONS

1. Tape Selection: Choose the Right Tape Size

• Select the appropriate tape size (thickness and width) based on your project’s specific performance requirements. Ensure that you have both Sikadur Combiflex® SG tape and Sikadur® adhesive ready for use.

2. Surface Preparation

• Prepare the concrete or substrate on both sides of the joint or crack by mechanical means, such as blast cleaning or grinding. This step is crucial to ensure proper adhesion and long-term performance. After mechanical preparation, vacuum the surface to remove any residual dust, debris, or contaminants.

3. Tape Welding

• Sikadur Combiflex® SG tape connections and overlaps must be welded together. This ensures a seamless and continuous waterproofing barrier. Make sure that the tape is laid flat and any wrinkles or folds are removed during this process.

4. Adhesive Application

• Apply the mixed Sikadur® adhesive on the sides of the joint or crack using a brush, trowel, or spatula. Ensure that the adhesive layer is uniform and covers the entire area that will come into contact with the Sikadur Combiflex® SG tape.

5. Tape Installation

• Immediately after applying the adhesive, press the Sikadur Combiflex® SG tape into the adhesive. It’s essential to ensure that the tape is firmly and uniformly embedded in the adhesive to create a strong bond. Use a roller to achieve an even surface and expel any air bubbles or voids beneath the tape.

6. Additional Adhesive Application

• Apply Sikadur® adhesive on top of the Sikadur Combiflex® SG tape. This additional layer of adhesive enhances the tape’s adhesion and reinforces the waterproofing seal.

7. Handling Sikadur Combiflex® SG M Type Tape

• If you are working with Sikadur Combiflex® SG M type tape, remove the red middle strip while the adhesive is still wet. This step ensures proper sealing and adhesion in the case of this specific tape type.

By following these construction instructions meticulously, you’ll ensure a reliable, watertight seal using the Sikadur-Combiflex® SG System. It’s essential to maintain precision and adhere to these steps to achieve the best results for your construction project.
