Unlevel Subfloor Below Laminate Flooring
Most laminate floor manufacturers require a subfloor to be flat within 3/16″ over a 10 foot radius.
Since not all laminate manufacturers have the same standard you need to check the installation instructions for the manufacturer of the floor being installed.
Some manufacturers instructions will use the word level instead of flat while they are actually speaking of the floor being free of high or low spots.
A subfloor that does not meet the laminate manufacturers installation requirements must be leveled by sanding or filled with an approved floor patching material.
On a floating floor gaps can easily develop between planks when a subfloor is not level.
