How do I fill gaps in vinyl tile??

Have you tried grout?

Just use some caulking in filling the gaps between the vinyl tiles. You can use the putty knife in pushing the caulking through the gaps in order to fill all those potential voids which could be under the edges of the vinyl tiles.

It may be a prep or a caulking technique that is giving you problems with the caulking staying between the tiles, take a look here at 2 ways to fix your problem:

Silicone caulk should work, just be sure to wipe away the excess before it dries. Can you tell us why it didn't work for you?

Many vinyl peel & press tiles are groutable. But if it's only a few gaps, that might look awkward. Try painting with a matching color.

HI Molly, the gaps were from the tiles slipping a part. Are they still moving? It might be possible to carefully pull them up and reglue them down with vinyl glue.

Not sure why caulking won't work. Ask at the paint counter for a different type. Also clean and dry the gap out before applying new.

Use the putty knife to push the caulking down into the gap so that it fills any potential voids that could be under the edges of the vinyl tiles. Pull the putty knife across the joint to ensure that any excess is scraped off the face of the tiles and the joint is filled flush.

do you mean the tile has gaps in it or the grout?

Try using grout instead of caulk. Comes in different colors

Grout is probably a better choice if you are going to do the entire floor. Good luck!

Hello Molly,

Use a waterproof sealer.

If the gap has been there for a while and any moisture has gotten in there, there is not much you can do that will last.

Clear caulk and a plastic putty knife to push it in. Wipe the putty knife clean between uses.

Hi Molly, sadly vinyl tiles tend to shrink over time, is used to use masking (painter's) tape to mask off the tiles and use a a white silicone on the gaps, peel the tape off as soon as you finish and place a chair over the area for it to dry, use a color that you think will blend in.
