UNDERLAYMENT SEAM TAPE 1. Push underlayment edges as close as possible 2. Unroll a few inches of tape and then make sure the center of the tape is over the underlayment seam. 3. Adhere the first few inches and then unroll a foot or two at a time, letting the tape gently lay over the seams. Press the tape over the seams for secure bond. Repeat procedure covering all seams. 4. Make sure you do not stretch the tape and press it on to the underlayment, this will cause the underlayment to bunch up.
