agree Superally, closer to 4-5mm but I found my glue gun to be ok, must be a different glue stick!2-3mm of fibreplan in my experience is not enough. You will still have exposed wires. When you lay the mat down bits of it will stick up so use small strips of duck tape to hold down. I found that the glue gun approach took too long. Glue takes a while to hold. You will always need more SLC than you think and it flows pretty easily, so make sure you have enough and maybe keep a bag spare. Last thing you want is to get to the last corner and run out. Good luck.....it gets pretty exciting when pouring.
