If you are remodeling your kitchen, you may question whether it is better to Remove a linoleum floor vs cover a linoleum. There are a few things to take into consideration before you make the decision.
Amount of Work
Either project will require a lot of work although generally it may be easier to cover the floor than to remove the floor. Removing old linoleum involves making sure it doesn't contain lead, scraping glue and disposing of all the flooring. You also will need to make sure the subloor is in good shape or it will also need to be replaced before putting new flooring on top of it.
Condition of Old Floor
If there are missing pieces of linoleum or deep cuts or tears you can still cover the floor with new linoleum but first you should fill in these places with floor leveler. This is a compound something like grout that can be purchased at any home improvement store. New linoleum needs a smooth surface to wear well.
If the sub-floor doesn't seem solid or if the linoleum seems to be crumbling, there is a moisture or rot problem and the linoleum should be removed before installing new.
