Suggested Installation Instructions.

The suggested installation instructions for our ULTRA NT SCIF Barrier are detailed below. These installation instructions should never be allowed to override your job’s specific architectural details and/or specifications.

Section 1: How to measure and cut our ULTRA NT SCIF Barrier

  1. Measure the surface area that needs to be covered with ULTRA NT SCIF Barrier then add 12 inches on each end or 24 inches overall to the length, because you must extend the ULTRA NT SCIF Barrier at the top of the wall onto the ceiling for 12 inches and also at the bottom of the wall onto the floor for 12” unless otherwise specified in the Architectural Specifications.

  2. Here is an example, if your wall height measures 84 inches tall you must add an additional 24 inches to the overall length so you can extend the SCIF Barrier onto both the floor and ceiling for 12 inches, this would make your overall required length 108 inches.
  1. Unroll the ULTRA NT SCIF Barrier onto a flat surface and measure the overall length required as detailed above then using a straight edge draw a straight line across the material then cut using a utility knife or scissors.

Section 2: How to measure, cut and install ULTRA NT SCIF Barrier in between two layers of drywall.

  1. Install your first layer of drywall onto your studs following all the architectural specifications and details for your specific job.

  2. Measure the surface area that needs to be covered with ULTRA NT SCIF Barrier then add 12 inches on each end or 24 inches overall to the length, because you must extend the ULTRA NT SCIF Barrier at the top of the wall onto the ceiling for 12 inches on also at the bottom of the wall onto the floor for 12” unless otherwise specified in the Architectural Specifications.

  3. Here is an example, if your wall height is 84 inches tall you must add an additional 24 inches extend the SCIF Barrier onto both the floor and ceiling for 12 inches, this would make your overall required length 108 inches.

  4. Unroll the ULTRA NT SCIF Barrier onto a flat surface and measure the overall required length as detailed above then using a straight edge draw a straight line across the material then cut using a utility knife or scissors.
  1. You have the option to make your 12-inch fold on the top and bottom section of your pre-cut ULTRA SCIF Barrier while it is still laying on your flat surface. This helps speed up and make a cleaner-looking installation.
  1. Install your first layer of ULTRA NT SCIF Barrier onto your drywall temporarily holding it in place with staples or 3M Super 77 general-purpose construction adhesive which is available in 24 fluid ounce spray cans or in five-gallon pails for larger areas. When you are applying 3M Super 77 General purpose construction adhesive for larger areas to drywall is using an inexpensive adjustable paint sprayer.
  1. As you are applying the ULTRA NT SCIF Barrier to your first layer of drywall remember that you must sure overlap all your side to side seem by six inches. Then you must tape all the seams using the tape that is specified in the architectural specifications and details for your project. Note: the most used tapes are shown below in section 3.
  1. After you have the ULTRA NT SCIF Barrier in place, and you have followed each step on your specified in the architectural specifications and details for your project. You can install your second layer of gypsum board on top of the ULTRA NT SCIF Barrier. The Manufacturer recommends using black phosphate fine thread drywall screws when installing your drywall unless otherwise specified in the Architectural Specifications.

One option when you are applying 3M Super 77 General purpose construction adhesive for larger areas to drywall is using an inexpensive adjustable paint sprayer.

The estimated coverage per five-gallon pail applied at .5 grams per square foot is 12,000 square feet and the estimated coverage per five-gallon pail applied at 1 gram per square foot is 6,000 square feet.

Section 4: How to prepare your concrete floor before installing your ULTRA NT SCIF Barrier

  1. Make sure that the concrete surface is as clean and dust free before beginning the installation of the ULTRA NT SCIF Barrier

  2. Make sure there are no jagged areas on your concrete floor that could cut into the ULTRA NT SCIF Barrier during the installation.

  3. Be sure to fill any cracks and or holes in your concrete with a concrete patching material before installing the ULTRA NT SCIF Barrier

Section 5: How to install ULTRA NT SCIF Barrier to your concrete slab.

If you want to install Ultra-NT SCIF Barrier onto your concrete floor using 3M Super 77 Construction Adhesive, here are the steps you can follow:

  1. Prepare the concrete floor: The concrete floor must be clean, dry, and free of any debris. Any unevenness or cracks in the surface of the concrete should be addressed before installing the barrier.

  2. Cut the barrier to size: Measure the dimensions of the area that needs to be covered and cut the Ultra-NT SCIF Barrier to size using a utility knife.

  3. Option 1: Spray the adhesive: Apply 3M Super 77 Construction Adhesive to the back of the Ultra-NT SCIF Barrier in a thin, even layer. Be sure to apply the adhesive to all edges and corners of the barrier.

  4. Option 2: Apply the 3M Super 77 Construction Adhesive to your concrete using a paint roller that is designed for painting concrete rolling the adhesive in a smooth layer at approximately 1 gram per square foot, each five-gallon pail of 3M Super 77 Multipurpose Adhesive will cover approximately 6,000 square feet when applied at 1 gram per square foot.

  5. Apply the barrier: Carefully align the Ultra-NT SCIF Barrier with the area of the concrete floor you want to cover and press it firmly into place. Use a hand roller or weighted roller to roll the barrier onto the concrete floor. This will help ensure that the adhesive makes good contact with the concrete surface and that the barrier is installed evenly.

  6. Secure the edges: Use conductive adhesive tape or a conductive caulk to seal the edges of the barrier and ensure that there are no gaps where RF signals can leak through.

  7. Test the barrier: Once the Ultra-NT SCIF Barrier is installed, you should test it to make sure that it is effective in blocking RF signals. This can be done using specialized testing equipment.

It is important to note that the installation of Ultra-NT SCIF Barrier can be complex and may require specialized knowledge and expertise. It is recommended that you consult with an experienced professional who can help you determine the best way to install the barrier and ensure that it is installed correctly.
