Hi,

I expected to install Tile on my bathroom floor so I installed Cement-fiber board. I have since decided to install vinyl sheet flooring.

Here is my concern: To smooth the floor I covered screw heads and seams in the Cement-fiber board with Thinset. The floor is now smooth. However the Vinyl adhesive requires a clean surface so I am worried that the thinset will cause the adhesive not to stick because when I rub the thinset, part of it comes off (almost like dust).

Should I be concerned? I really do not want to put down another underlayment over the Cement-fiber board .

Thanks for your help,

Mike

I'm not sure the thinset will be a good enough substrate under the vinyl. I don't remember if you said you taped the joints with mesh tape but I think you should. Try covering the entire floor with a thincoat of floorpatch. Just spread it with the flatside of your trowel. Also I'm fairly sure that the grey floorpatch is reccomended over the white patch, but either one can be gotten pretty cheaply at your local bigbox store.

Thanks for you quick response to my question. Yes, I taped the joints. I'm not sure what product you mean when you say Floorpatch. I am in California (SF) and don't recognize the store you mention. Would Home Depot or Lowes carry a similar product?

Thanks,

Mike

When I said bigbox store; I meant Home Depot or Lowes. I just didn't want to promote one or the other. It could also be another store that you have locally that I never heard of. Sorry for the vagueness.

Floorpatch is a product that you skimcoat the floor with to smooth it out, fix small indentations, float minor uneven areas, and cover stuff up; in this case thinset.They sell it at either place in the flooring department by the vinyl. Custom and Mapei might make some, but another one is called white dependable. This is the one they've used forever but it's Gypsum based (white). Try to find one that is grey, I think they're better as far as longterm coloring of the vinyl.If you don't see it right away just ask someone there where the floorpatch is and they should know what you mean.

I have vinyl self stick floor that I am installing in my dining room. I have installed it over ceramic tile in the kitchen but had to raise the dining floor 1/4 of an inch. I used plywood but it is warping. My thought is possibly using cement board to build it up. Is this n option?
