This is picture of door opening where my dining room (laminate) floor meets kitchen vinyl. I recently created door opening in wall and now I am planning to install new vinyl flooring on kitchen side.(bottom side of picture). My question is how can i fill dents and level the subfloor where 2 floors will meet before installing floor and transition strip. What should I use to fill and level ?

  • Will you be removing the old vinyl or install new vinyl over old?

If this is under a door, then a simple answer may be to just install a threshold or "junction", typically a metal strip used to join a carpeted floor to a non-carpeted floor, or when two types of mis-matched carpet meet. These "junctions" could be lumber, sheet metal, sheet copper or brass, or something more stylishly related to your home.


You'll need to fill it with whatever wood and plywood you have on hand, then skim with a leveler designed for vinyl floor preparation. Any home improvement store can suggest one.
