The primer is easy to recommend. Simply fill with a paint roller on the ground, apply to invigorating. At first I was a bit cautious and have little taken. But I noticed that the primer dries very quickly and have plenty of post-rolled. The result is holding a rubber layer on the self-adhesive vinyl tiles outstanding.
But you should note that you will no longer run after drying over because firstly it takes sticking socks and remain second sticking dirt on the ground. Thus, working from the farthest corner of the door and the best piece by piece on a train with the laying of the tiles.
