Query: very difficult to apply smoothly

This product works great as a white board but it was impossible to apply smoothly. I had 2 people applying it and still it has wrinkles in the middle. The adhesive is unforgiving and the product so thin it is impossible to control. We ended up having to slice down the middle of each wrinkle so that it could be overlapped and flat. This of course left it looking like there were cracks in the board.
