Step One: Ensure that the surface of your weep-hole is free of any dust or grime. Wire brush and wipe down as necessary to establish a clean brick surface for your silicone.
Step Two: Remove the stainless steel screen insert so as not to clog with silicone during the installation.
Step Three: Apply a bead of silicone across the top and bottom ends of the back of the mounting frame. (This is the same side that has adhesive tape)
Step Four: Remove the protective paper from the adhesive tape and mounting frame over the weep-hole. Ensure that the frame is vertical and the same height and position as the other weep-holes you have installed. The vent has a wide end and a narrow end on the frame, the narrow end is generally placed down. This narrow end allows you to place the screen closer to any protruding bricks or ridges.
Step Five: Once the mounting frame is adhered to the wall, run a bead of silicone around the outside of the frame (between the device and the brick surface) uneven mortar or bricks will cause voids, these voids must be "filled in" with silicone rubber. In some cases where voids are very large, additional silicone rubber may be applied to the interior of the mounting frame. A seal between the frame and the brick is necessary to ensure the effectiveness of the Guest Control Weep-Hole Vent screen.
Step Six: Let silicone dry and then re-install the stainless steel screen and inspect your silicone seal and fill in any voids that might have been overlooked during the initial sealing.
