How to place engineered hardwood against rough fireplace hearth?
Use a transition &quot;tee&quot; molding used for setting between 2 different runs of floor. One edge can be shaped to conform to the stone, it will match the color of the floor you choose and will give the required movement the flooring needs. It will look, in my opinion, less conspicuous once in place. That is if it is a floating installation. If it is a glue or nail down, scribe to fit it tight, that's all you will need to do.
