I have ceramic tile and carpet being installed in a loft (transitioning between a kitchen area and a living room area) I want the base boards of course even throughout. Should they go down on the subfloor prior to both installations or afterwards? Thank you.
I wouldn't even want to guess without any info. Need to know the thickness of materials and method of installation, especially for the tiles.
However.......It's likely the base can be installed prior to installation, but shimmed up about 3/8 -1/2". Carpet gets tucked to the base. Tiles are installed to within 1/4" of base, gap left unfilled, then shoe moldings installed.
Of course you'll install a concrete backer or matting under the tiles. Sometimes tiles are installed over a mortar base that is about an inch or more thick. Tell us more.
