An initial sample allowed us to see that the Click would work and put down the MCT tiles.
Picking up materials at Bell Flooring, above.
Below can be seen the concrete underneath, the foam underlayment and the 'Click' sandwich of cork, composite board and Marmoleum. It is about 3/8 inch thick, is tapped into place and floats without any glue. We ran out of materials and have to wait for backordered planks to arrive.
Meanwhile, Alan can install the Marmoleum Composite Tile, which is a thin layer linoleum tile that is glued right to the concrete. Very carefully!
