[QUOTE="Spiker, post: 637317, member: 102150"] At the start of week 4 I really should have done a reinforcing job on the tape. I didn't, and the sensor was looking decidedly wobbly in the shower this morning so I went for a full repair job. For those unfamiliar with the process, the number one limitation on G4 sensor stretching is not the electronics, it's the sticky. My first Tip To Self for a repair job is get all the tape and sticky you need opened and cut and prepped as much as humanly possible. Why? Because during the tape repair operation you are going to be holding the sensor onto you with one hand and doing all the repair work with the other hand. And one slip means goodbye sensor and goodbye fifty quid. I forgot to prep properly and so I was holding the sensor on with my elbow while cutting patches. First I cleaned away all the old tape and Tegaderm and sticky from the previous 3 weeks until I was down just to the adhesive oval that originally sticks the sensor on. Trying to remove this is not wise, even when it's completely lost all its sticky. My first repair is a single piece of Tegaderm, folded lengthwise and widthwise to make lines. Then you fold it along its long axis and the line from folding it the other way shows you where the centre is. I cut out a diamond (half a diamond since its folded in half) in roughly the size of the sensor. I rip the last piece of waxpaper lining off the Tegaderm and position the Tegaderm over the sensor. You don't get too much adhesion round the edges with a singe piece so care is still needed. The open diamond is to allow the sensor to radiate heat so it doesn't burn out. I then quickly attached two entire pieces of Tegaderm above and below the sensor. I only overlap enough Tegaderm onto the sensor to attach to the sides of the sensor and overlap onto its original oval piece of fabric plaster. For this part in particular it is important to stand up, otherwise as soon as you do stand up your skin will stretch and the Tegaderm (or Opsite or whatever you are using) will be too tight and need to come off. I now have a secure foundation that will last another one to two weeks. I have controlled the risk of the sensor falling out, even in the shower, and I have also cleaned away lots of ****** old adhesive etc that makes the site look manky and possibly harbours germs.
