Getting ready to glue down engineered hardwood. I have a crack down the center of my floor, wall to wall about 4 feet from the furthest wall. I layed a level from one side of the crack to the furthest wall and there's about an inch gap at the furthest point.
Question is how do I fix this? Do i just pour auto leveling cement or grind where the crack is?
What would it look like if you used an 8 or 10 ft. straight edge? Is the side you didn't mention flat all the way to the crack?
Thanks for the reply
Yes, each side of the crack is flat if I lay a board/level. But from one side of the crack to the other, its about an inch of a gap.
See the attach drawing. The vertical and horizontal lines are the cracks. The other line represents a straight board. All of the red sections are fairly flat to each other. But from the 8 foot side to the 4 foot side is where there's a large gap.
