Vinyl flooring is a synthetic material that is good for spill-prone areas in your home, such as kitchens and bathrooms. While vinyl can be purchased in large sheets, you can also find the flooring in smaller tiles that are easier to manage and install. Seam sealer is available in hardware stores -- the clear liquid fuses the seams of adjoining tiles together to avoid peeling corners and joints over time. Seam sealer is easy to apply to new and old tiles.
Allow newly installed tiles 24 hours to set in their adhesive before applying seam sealer. This affords the tiles ample time to become affixed to the floor. Tiles that have been installed for more than 24 hours can be worked on immediately.
Dip a soft cloth in lacquer thinner and wipe down all tile seams. This will ensure that no remnants of tile adhesive or dirt are present in the seams. Allow the tiles to dry.
Squeeze a thin line of seam sealer along the tile seams. Don't apply too much sealer -- a thin bead line will suffice. The sealer will permanently bond the tiles together.
Clean up excess sealer while it is still wet using a cloth dipped in white spirit; rub the cloth in a small circular motion.
Seam sealer can also be used to fix minor scratches and tears on the surface of a vinyl tile.
