Vinyl flooring tiles are elastic, soft floor sheets that come with many degrees of adhesive strengths. Some tiles have an adhesive backing, while others use another adhesive, or adhesive, to hold them in place. There are numerous reasons why a vinyl tile may come loose, from insufficient amounts of adhesive, to insufficient amounts of pressure at installation. Irrespective of why the tiles are coming loose, reset them properly to ensure they stay down in the future.
Tape off the edges of any nearby tiles that aren’t loose. This can help prevent any damage to their edges while you remove the old adhesive of the tile.
Use a putty knife to scrape up any old adhesive. The flatter you are able to get the floor, the more the new tiles will lay down. If needed, heat up the old adhesive with a hair dryer to soften it and allow it to come up easier.
Vacuum the floor where you can re-lay the tiles. Get up any loose adhesive or debris that may interfere with the new glue’s bond.
Spread an even coating of vinyl tile adhesive over the region where you are installing the loose tiles. Use a trowel to rake the adhesive until it is even in thickness. Press down the tiles into position.
Roll the floor with a flooring roller to assist the tiles bond with the substrate. The floor roller will exert many hundred pounds of strain on the floor. This can help prevent the tiles out of coming up again in the future.
