When you replace resilient flooring tiles, use the adhesive the manufacturer specifies.
If your flooring is old, you may need to take a sample to a flooring materials supplier and ask what kind of adhesive is recommended. Also be sure you know what kind of subfloor you have. It may be that you cannot find a matching tile to make a repair.
Consider using a complementary or even contrasting color or design. To replace a damaged tile, warm the tile with a hair dryer, iron, or propane torch until it begins to lift up. With the help of a putty knife, peel the tile up and scrape off the old adhesive.
Using a notched spreader or trowel, apply the recommended adhesive on the subfloor and push the tile firmly into place. Wipe away any excess adhesive.
To replace tiles over a concrete slab with residual adhesive, first try to remove most of the old adhesive with a heat gun and a scraper. Then use a latex-modified thinset over the mastic.
