What "green" sealant would you recommend for tile in my entryway?

This is a fairly high-traffic area. We want to keep cleaning easy. We assume the sealant will protect grout as well.

AFM Safecoat Penetrating WaterStop is a zero-VOC sealer that increases water-repellency on brick walls, concrete foundations, stucco, stone, and most unglazed tile. It is nonflammable and free of formaldehyde and hazardous ingredients.

But, putting a sealant over tile may make it very slippery.  Also sealing depends on the type of tile.

If you are using a glazed tile, you don't need to seal it.

  • Just seal the grout joints, and
  • you should wait a week or so to make sure the grout is completely set and dry.
