| Is Underlayment needed for Vinyl over screwed cushion tile
Last year I installed a floating Formica glued laminate floor in my kitchen over a cushioned vinyl tile original floor. Six weeks later an upstairs commode ran over while we were away and flooded the kitchen floor. The insurance company had the floor dried out and all appeared well for a few months. Recently, the edges started cracking at the seams. I plan to remove the laminate floor and install vinyl sheet or tile. The original floor was installed in '95 over 3/4" T&G plywood with 1/4" plywood underlayment attached with ringed nails on 6" centers. Within a year, the outline of the nail heads could be seen in the cushioned tile. As time passed, several places began to squeak everytime someone walked on them. Before I put the laminate floor down, I put SEVERAL pounds of ringed nails and screws through the cushioned vinyl to reduce squeaking. It is not practical to remove all the nails and screws. I plan to put luan or similar underlayment down before installing the new vinyl flooring. Is ther any particular way this should be done? Is there a better way to address this?
