  • Easier to clean: Since sealed grout does not stain as easy, you spend less time scrubbing when a mess occurs.
  • Save on maintenance: Grout that becomes dirty from grim and water eventually breaks up, causing the tiles to break-up and eventually need to be replaced. Grout sealing slows down damage and extends the time before you need to re-tile.
  • Slow down wear-and-tear: Grout sealer binds itself to the grout, strengthening it and slowing down the time it takes to break down and need replacement.
