Self-adhesive floor tiles

I used some self-stick tiles in a bathroom and it actually turned out very nice and is holding up well. However, in some spots where the tiles meet there were mere hairline gaps and I used some colored caulk, but that didn't work out real well for these hairline gaps.

Does someone know of something I could use just to fill in these hairline gaps to make things look more uniform? I've done some Googling on this but have read that most of these tiles are too thin to use grout on. I can't see what their thinness would have to do with grout but I'm a newbie at this stuff. I've also read that the self-stick groutable tiles are not recommended, although it never really said why.

I'd appreciate any help because I have another very small bathroom I'd like to do.

Thanks!

 

Grout is for ceramic tile, when it's installed it's ridged so the grout wont flex and break.

Vinyl tile is thin and flexible so gout wont last.

Vinyl self stick tiles are not really a long term flooring so you get what you pay for!

 

I don't think there really is a good fix
I suppose you could fill the gap with spackling [use a wet rag/sponge to remove the excess] and then use an artist brush to paint over the spackle.

 

Most of the self-stick tiles are so poorly made that they are not square. So it is common to see gaps. They won't last more than a few months anyway. On some brands the thin top layer with the pattern will peel off. But with most the whole tile will release or a corner will curl. They are intended for a temporary floor.

 

Thanks for your input. I have to disagree about the tile not holding up. It has and is holding up really well in the bathroom I've already put it in. And the hairline cracks I talked about aren't significant, but even so, I was hoping to find a way to do away with them. Actually, that spackle idea might work.

 

Normally the self stick tiles don't hold up well. I've seen many of them that didn't last a year but there are always exceptions. One of my stepsons put it in his kitchen. I told him I thought it was a mistake but he liked that it was cheap and easy. I was shocked that 3 yrs later when he sold the house that the floor still looked good.
