Can this be installed directly over tile in kitchen and laminate in dining room?

Hello and thanks for your inquiry. The ProCore Plus Luxury Vinyl Plank can be installed over tile. However, we recommend using a suitable patching or leveling compound to fill in the grout joints prior to installing the new flooring. For product recommendations, please speak with a flooring specialist at your local Lowe's store. We also recommend removing any floating floor systems such as laminates before installing ProCore Plus. Please review the Installation and Warranty Guides (found on the product page of the Lowe's website, or in the carton) prior to installation. Thanks again.
