How to Seal Self-Stick Vinyl Tiles


Self-stick vinyl tiles are a popular choice among homeowners who want a new flooring look with a low investment of time and money. Because of vinyl's porous nature, dirt will become ground into the tiles over time, resulting in a dingy finish. In addition, vinyl tiles are prone to water damage. Applying a sealant over self-stick tiles will form a hard barrier and help ensure the longevity of the tiles.

Step 3

Pour the sealant into a bucket, and dip a mop with a sponge head into the bucket. Press out the sponge so it is not dripping.

Step 4

Apply a thin layer of sealant to the tiles, beginning along the wall and turning the mop at the edge of the walls to form a U-shape and travel in the opposite direction. This will prevent you from going over the same section twice.

Step 5

Allow the sealant to dry for four or five hours. The sealant will appear milky white when applied, but it will be clear when dry.

Tips & Warnings

  • If the flooring begins to yellow after applying sealant, clean with a Magic Eraser, then apply a new coat of sealant.
  • Do not apply one thick layer of sealant in place of two thin coats. It will not harden properly.
