It is generally not recommended to install laminate flooring directly on top of vinyl plank flooring. Laminate flooring is typically designed to be installed on a subfloor or underlayment, whereas vinyl plank flooring is typically a floating floor that is installed without adhesives directly on the subfloor or an underlayment. Placing laminate flooring directly on top of vinyl plank flooring can result in an unstable and uneven surface, which can lead to problems such as movement, buckling, or squeaking of the laminate.
If you are considering installing laminate flooring over vinyl plank flooring, it is advisable to remove the vinyl plank flooring first. This will allow you to properly prepare the subfloor, ensure a smooth and level surface, and create a suitable foundation for the laminate flooring installation. Removing the vinyl plank flooring may require some effort, but it is generally the recommended approach to achieve a successful and durable laminate flooring installation.
