Can I put HardieBacker® cement board over linoleum or vinyl composite tile?
» Yes, HardieBacker® cement board can go over linoleum or vinyl composite tile. Even though you may go over vinyl composite tile, James Hardie does not recommend you install HardieBacker® cement board over cushioned vinyl. Follow HardieBacker® cement board floor installation instructions for complete details. However, it is much better to remove all existing floor coverings and fix the HardieBacker® cement board direct to the substrate.
