Armstrong Alterna

Barry2080

I am about to embark on rather large floor project [600 sq ft] using Armstrong Alterna groutable floor tile. I am removing a non glued sheet flooring that was installed over 1 quarter in. luan plywood. My question, is this a suitable underlayment for this product? Also any help or tips would be greatly appreciated. The sheet flooring of course will be removed and the sub floor is three quarter thick on 16 in centers. Thank You

Armstrong Alterna can be installed over the existing vinyl, by using skimcoating, 1/4" sub-floor (multi-ply) or underfloor.
Thus, if you remove the existing flooring, you would need a 1/4" sub-floor.
