I recently had some vinyl laid in the kitchen. I advised the store that the original vinyl was laid on a concrete slab and that the previous installer used a full glue instead of a perimeter glue. The store stated that they would have to lay 6 sheets of 4x8 1/4 inch Luan underlayment before putting down the new vinyl and then they would have to use some type of leveling compound to fill the cracks in the Luan. When the installers arrived, they advised that they could not put down the Luan because they would have to nail it to the floor and that could not be done on the concrete slab. They said they would just put down the leveling compound and that would save alot of money compared to the Luan underlayment. Well. . . I called the store and asked that they take the $300.00 charge for the Luan underlayment off my bill and they said that the leveling compound costs $1.75 per square foot and that he would only charge me $1.50 per square foot making it $301.50 (which is what I was billed for the installation). There is also a charge on my bill for $80.40 for floor prep. My floor is 12x16'9" (201 sq ft.) I feel like they are trying to rip me off. Can anyone advise? Thanks!

i read these posts too late. not only are my knuckles raw, i can't take it all up because the new cabinets are already in. now what? do i use something like ardex? i still haven't decided between laminate vinyl sheet and vinyl tiles. will that work under any of these? thanks, paula.
