My son is getting ready to start cutting the tiles for an endgrain floor in our kitchen. It is going to be a huge project but I was really interested in getting any feedback from any one who has any experience with this. I saw what Tom Porter did and it seems like we are on the right track we just havea few obstacles to get through like leveling out the floor once we tear the old out. Do anyone know if we have to put the the plyboard over the subfloor? I know we have to have a vapor layer but you cannot adhere to the vapor layer. I am thinking we have to put the subfloor, vapor layer and then maybe 1/8” plyboard and then we can lay the tiles but this will jack up the height of the floor.
