I screwed up the floor underlayment before installing vinyl tile. I wasn't able to smooth it before it dried.
Question:My question is: will I have to sand it down? There are several small ridges about 1/4 inch high. What will happen if I just lay the tile over it?
Answers:
if by underlayment you mean some kind of self levelor, i think thats what your talking about. it also depends on what kind of vinyl your using. if its some cheap real thin one then yes that would effect it. if you bought a thicker tile (you would be able to tell if it was significantly thicker) you might be alright as long as the floor isnt that not-level. if the tile doesnt work try and it comes up or wont lay good get yourself some vinyl tile adhesive thats what its called not sheet vinyl adhesive, vinyl tile adhesive. use that on the tiles that wont stay. if that wont stay try leveling your floor completely again. it can be done twice, try a self levelor lay it up to an inch thick and it levels itself out. $30 a bag and thats what i would recommind doing.
even though its vinyl it will crack!
floors always only as good as the subfloor; you gotta level it
Being vinyl certainly if it doesn't crack it will eventually conform to the shapes of any rise or void beneath it.
I'm curious about what the substrate might be that even caused you to do underlayment for a vinyl tile?
