I used an embossing leveler over an existing resilient floor and still have bumps and ridges showing through my new flooring. Why?
You may not have completely filled in the embossing with the embossing leveler. When using an embossing leveler the product fills in the low places or embossed areas of the existing flooring. If the embossing is deep, two layers must be applied. Once the first layer is done, you need to determine if the leveler is even with the surface of the flooring. If not, then another application is required.
