How many layers of linoleum is considered the max?

Although your existing layers of flooring may be in good shape now, in the event that the adhesive fails on either one, the top layer will be affected as well.

My advice is never to layer.

Depends on the condition of the linoleum. If there is no holes or such, you can go over it. I've seen up to three. Honestly, it's better to take it down to the subfloor, patch and make repairs to the subfloor and the install the new linoleum.

In my world, one. You should always remove old flooring and inspect and repair the sub floor as needed before installing a new floor, no matter what type. Period, point blank, end of story. There are a few, very few exceptions. Your flooring is only as good as the subfloor it is placed upon. I have seen as many as 3 but the place looked horrible to be polite. My flooring guys will refuse jobs if they are not to be installed properly. They will not cut corners or cheap out. For one, it looks tacky, and two, it compromises the integrity of the floor. Yes, I feel very strongly about this subject! 😊

Maggie, having been raised in the flooring industry and in it for 15 years, two would be max. It is always preferable to start on the base flooring to keep adhesion to its maximum efficiency!

My husband used to do that for a living and he says you can put ONE over the old one. After that, you need to remove the layers.
