Konecto with Underlayment

Q: I am interested in using the Konecto vinyl planks in my kitchen/breakfast nook/den. Unfortunately the existing flooring is the old ’70s style “brick” sheet vinyl. Pulling this up may run into an asbestos issue. I believe laying any “soft” product on top will eventually end up picking up the embossing. The research I’ve done indicates that an embossing leveler would be an option but as a DIYer I’d rather work with an underlayment (no mess, pet pawprints). What are your thoughts on using the Sound6 II as a base for the Konecto? What would be your alternate options?
Thanks so much for your help,

A: Konecto specifically mentions to NOT use any type of soft underlayment or subflooring with their products. They do mention that you will need a leveling compound for things like highly embossed tile and to fill grout lines, but as long as these variations are not more than about 1/16″ you should not need to worry.
If you are ultimately concerned with using an underlayment to account for the embossing, you would need to use something fairly dense. Cork could be an option, but I would contact Konecto directly to find out before purchasing any cork or proceeding with installation. The key here is not to ruin the inherent strength of Konecto’s product and locking mechanism by installing it over an unsuitable surface.
