hello all I am renovating my house and during the process i have removed one of the load bearing walls that was separating my kitchen from the living room. In the space where the wall set i have placed a 3/4 inch plywood to fill the void but now i have noticed that the floor in the living room (3/4 inch particle board) is not even with the kitchen floor (plywood). My first thought was to use a self leveler but that being water based it will make the particle board swell up so now i am thinking about applying some kind of a paint/primer/sealer to the particle board prior to putting down the self leveler. I know that many of you will say that i should just replace the particle board with plywood but i feel that its too much money and work for this project. The plan is to put a Armstrong click and lock engineered hardwood floor in the kitchen as well as the living room (which is actually just one big room now). What are you thoughts on this? What product would you recommend that i use?
