Floor Not Flat

Although floors in the home were out of level and not flat this is always the case.
Floor not flat. Here s how flat floor and level floor are different. Flat means no significant high or low spots. Near the door there is an empty space under the flooring so that the flooring bounces. Slide the tongue of laminate being inserted into the laminate already on the floor.
Not being flat can cause problems with plank adherence to the floor hollow spots t g not fitting correctly etc. You should decide by walking through the home whether the floor structure is a problem for you. There is a laminate floor that looks like wood floors. The bulges probably mean that the floor is not flat which means starting over again i m afraid.
As you are moving the piece into the grooves on the flat piece lower the piece in your hand as you are pushing it together with the flat piece. Also check for any damp areas this would swell the laminate if wood. And don t forget to lay an underlay felt or a rubber composite type floor covering. Snap together the sides of the laminate pieces together by holding the piece you need to install upwards.
I would consult with nwfa the national wood flooring association for any additional symptomatic problems that may exist. We have a new garage and 2nd floor above the garage. The question is is the floor flat. Before it was barely noticeable but now it bounces between 1 4 and 1 2.
In the tile world the word flat means that the surface does not have any significant high or low spots and will yield a smooth tile installation with no lippage between tile edges.
