Installing bond breaker tape, such as Ardex sdb tape, involves applying it firmly to the desired surface. A key step in this process, as demonstrated in some installations, is applying pressure while removing the tape backing in sections.
Understanding Bond Breaker Tape
Bond breaker tape is typically used in waterproofing systems at joints or changes in plane (like wall-to-floor junctions). It prevents the waterproofing membrane from bonding directly across these areas, allowing for movement and helping to prevent cracks in the membrane.
Step-by-Step Installation (Based on Reference)
While installation methods may vary slightly depending on the specific product and application area, a common technique involves careful placement and firm pressure. Based on the provided reference, here's one way bond breaker tape is installed:
- Position the Tape: Align the bond breaker tape in the desired location, ensuring it covers the joint or area requiring the bond break.
- Start Applying Pressure: Begin pressing the tape down firmly onto the surface.
- Peel Back One Half of Backing: While maintaining pressure on the applied portion, remove the tape backing from one half of the remaining unadhered section.
- Press Down Firmly: Press the tape down firmly onto the surface as you remove the backing from that half.
- Repeat for the Other Side: Then, repeat the process for the other side, removing the remaining backing and pressing firmly down using your hand to ensure full contact and adhesion.
This method of removing the backing in halves allows for more controlled application and helps prevent the tape from sticking to itself or the wrong area before it is properly positioned and pressed down.
Why Firm Pressure Matters
Applying firm pressure during installation is crucial. It ensures that the adhesive on the bond breaker tape makes full contact with the substrate, eliminating air bubbles and providing a secure bond. This secure bond is essential for the tape to perform its function correctly within the waterproofing system.
Note: Always refer to the manufacturer's specific installation instructions for the bond breaker tape product you are using, as techniques and preparation steps may vary.
