I am getting ready to yank the nasty carpet out of my kitchen, mop the nasty carpet padding stained VCT and put down 1/4" backer board. I plan on using the spacing of screws recommended by Hardibacker.

Am I wasting my time using Thinset between the backer board and the VCT?

I don't know how well it sticks to vinyl, but I know enough that I don't want to stir up any more dust removing VCT due to possibility of asbestos being used in the 1964 home. The thinset worked well on the painted bathroom plywood under the 1/2" backer board.

I am using modified thinset purchased at Lowes. I am not sure what brand.

Thanks for your suggestions.

Should I just paint over the VCT to seal in an possible carcinogenic dust? I have a can of $5 mistint paint from sears.

The purpose of the thinset is not to "glue donw" the backer board. You will have enough fasterners in it to hold it down.

It being used as a filler so that there is 100% contact between the backerboard and substrate (the VCT's in this case).

Backerboard is somewhat brittle and it there where high and low spots so that the backerboard was not 100% supported then it would crack.

And no need to "seal" the VCT.
