| Usage Visqueen Zedex DPC Surface Fixing System is designed for use with surface fixed DPC cavity trays and Preformed Units supplied by Visqueen. Please note that separate surface fixing products are available for Visqueen Zedex Non-Combustible Damp Proof Course, Visqueen Zedex Non-Combustible Flexi Preformed Units and Visqueen Non-Combustible Preformed Units. | |
| Storage and Handling Visqueen Zedex DPC Surface Fixing System products should be stored in a warm, dry and clean environment in their original packaging.
Care should be taken when handling the products in line with current manual handling regulations. | |
| Preparation Ensure the substrate is clean, dry and free from sharp protrusions. | |
| Installation Masonry substrates e.g. concrete, brickwork, blockwork.
When surface fixing to the cavity face of a masonry inner leaf substrate, prime a 100mm band of the substrate at the appropriate height with Visqueen HP Tanking Primer and allow to dry. Apply a continuous strip of Visqueen 100mm Double Sided Butyl Tape to the primed substrate and bond the vertical flange of the cavity tray to the tape. Roller to ensure an effective bond. Secure the surface fixed cavity tray in position with Visqueen Zedex Fixing Strip and Visqueen Zedex Fixing Pins for Masonry.
In order to install Visqueen Zedex Fixing Pins for Masonry, drill a 6.5mm diameter by 50mm deep hole into the substrate. Insert the fixing pin and tap the central plastic nail firmly home into the fixing pin. The fixing pin will expand giving a secure grip into the substrate. Progressively repeat the process for each hole in the fixing strip.
Timber or weather defence board substrates.
When surface fixing to timber frame or the weather defence boards of lightweight structural framing systems, follow the above procedure but replace the fixing pins with suitable stainless steel fixings appropriate for the substrate.
Insulation substrates.
When surface fixing to the rigid urethane foam insulation of a SFS substrate, apply a continuous strip of Visqueen 100mm Double Sided Butyl Tape to the substrate and bond the vertical flange of the cavity tray to the jointing tape. Roller to ensure an effective bond. Secure the surface fixed cavity tray in position with Visqueen Zedex Fixing Strip and Visqueen Zedex Fixing Pins for Insulation.
In order to install Visqueen Zedex Fixing Pins for Insulation, form a pilot hole using a bradawl or similar prior to inserting the fixing pin. Progressively repeat the process for each hole in the fixing strip. | |
| Usable temperature range It is recommended that the Visqueen Zedex DPC Surface Fixing System should be installed above 5°C. | |
| Additional information Visqueen Preformed Units are available for complex or awkward junctions of the cavity tray e.g. internal corners, external corners, changes of level, etc.
