im trying to cover a tile bathroom floor with self stick...i'm assuming i need to use mastic to fill in the grout lines and help the new stuff stick, but what do i use to take the sheen off the old tile to make sure it stays stuck

Unlike stucco or mortar, self-stick tiles adhere best to a smooth surface. Think of them as large thick squares of cellphane (scotch) tape.

The main thing is to make sure that there are not bumps or bits of debris sticking up that would keep them from lying flat. Sweep & vacuum several times, then go over the surface with some sort of dust rag.

In the past 15 years, I have used these in 3 bathrooms and an entryway and they have held up remarkably well. A cat even flooded one of the bathrooms and the tiles stayed stuck.

so your saying apply the mastic make sure it's smooth and don't worry about getting the shiny off the old tiles?

That's pretty much the idea. Unless It is shiney from some sort of waxy or oily coating that the new tiles won't stick to.

You could try a bit of test tile in a corner to see how well it sticks. That way you wouldn't end up wasting time or materials by over-prepping or under-prepping the floor.

I learned the hard way about pre-testing materials during a disasterous paint job on a project in middle school.

Might help to upload a pic of the old/existing floor. If you previously had some kind of linoleum or vinyl tile, they could do with a coat of deglosser/primer that they sell at home centers in the flooring section. You could also lightly sand with abrasive pads or sandpaper but that releases possibly toxic dust that needs to be properly cleaned up. Do fill with a floor leveler/grout so the base is completely flat. Good luck.

Are these like ceramic tiles, where you have grout lines? IF so you would need to do one of two things......either remove the old tiles, and the mastic (a TON of work) by chippint the tiles up, then sanding the floor smooth.....IF you have cracks or uneven places you would need to do the second choice anyway.

OR (and this is what we did) buy a bucket of a "liquidy" floor leveler at your local Big Box Store. It's kind of like a thinnish cement. You make sure the floor is clean, then mix it (if directed) and pour it onto the floor.....it will fill any low spots (grout lines), or any other imperfections. You MIGHT have to move it around a LITTLE. Let it dry untouched, then you have a perfect floor on which to apply the tiles.
