The problem of the door strip and the drop are two different things, the door strip is not good may be the uneven ground when the floor is paved, resulting in the strip and the floor surface can not be completely fitted, so the glue is not sticky, and there is a very small possibility that the master is sloppy when the glue is played. And whether you have a gap or not, the door is generally used to press the strip, if you don't use it, in case there is a broken one in the future, you will be very troublesome to repair. In a word, the problem of the gap, you have no problem with the home mat, don't worry.

The pressure strip at the door is recommended for you.
