How to Use a Vinyl Tile Seam Sealer

Updated February 21, 2017

Vinyl tiles are commonly used as a do-it-yourself flooring material due to the user friendly properties of the tiles themselves. While vinyl tiles are a viable material for wet areas such as kitchens and bathrooms, many homeowners encounter moisture problems due to the fact that the tiles have so many exposed seams. One solution to this dilemma is to use vinyl floor seam sealer on each tile seam to completely seal the flooring from moisture infiltration.

Clean the vinyl tile seams, taking care to remove all dirt, dust and adhesive residues from the edges of the tiles. Allow to dry completely.

Pour a small amount of seam sealer onto the felt pad applicator that is part of the seam sealer kit.

Rub the sealer onto each seam, using a back-and-forth motion and rubbing seven or eight times on each side of the tiles; add more sealer as needed as you work along the seams. Contain the application to a width 1/2 to 3/4 inch at the seam.

Wipe up all excess seam sealer immediately, using a lint-free cloth to remove all sealer except that which is directly on the seam. Allow the remaining sealer to air dry for five minutes.

Buff the seams, using a clean lint-free cloth to remove all residue of sealer from the seams.


Vinyl seam sealer comes in both high and low gloss; purchase the type that matches your floor finish.


Always follow the seam sealer and flooring manufacturer's instructions when sealing vinyl floor seams.
