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.
