Instructions to Seal Grout on Porcelain & Ceramic Wall Tiles

Porcelain tile is water resistant, but the grout that is used to hold it in place is porous, so it is quite vulnerable to the moisture. To protect it against the moisture, penetration of the grout and damage to the tiles, it is necessary to seal the grout. This extra step protects your new floor, wall, or dashboard for many years to come. In this post, I will talk about the instructions to do it.

Instructions to Seal Grout on Porcelain Tiles

  • Wait four or five days after installing the tile for the grout to heal.
  • Clean the tile of dust or grit that the tile could have collected while they were cured from the grout and allow to dry overnight before applying the grout sealer.
  • Apply a layer of grout sealer to the grout joints with a paint brush and use a rag to clean the sealer that runs over the tile and grout and allow the sealer to dry for at least one hour.
  • Now you can apply the second layer of the grout sealer and follow the same process.

How to Seal the Grout on Ceramic Wall Tiles?

Glazed ceramic tile is completely moisture-proof and stain-resistant, but not grout between the tiles. It is a kind of cement, and like any cement, it will absorb moisture and stains if it is not sealed properly. The grout sealer is a clear liquid coating to protect it and it will also seal on the stains in the grout, so it is important that the grout should be cleaned before you start sealing it.

Instructions

  • Clean the surface of the tile with a tile cleaner.
  • Fill a spray bottle with a combination of half water and half bleach and produce enough of the solution to cover the entire wall.
  • Spray the chlorine solution on the grout lines at the top of the wall, covering a stretch of a few square feet. Wet the lines completely and let the solution stand for one to two minutes and then rub with a small brush and rinse very well.
  • Repeat the process over the entire wall. Look for any bleaches or stains that were not removed and work on them specifically until they are gone.
  • Allow the grout to dry for two to three days. Any remaining moisture in the grout during the sealing process will cause the sealant to fail.
  • Brush your grout sealer into the grout lines with a small foam brush, from the top of the wall and down applying slowly on the flat lines. Avoid letting it reach the surface of the tile. If it enters the tile, wipe the edge with a damp cloth.

Allow the grout sealer to dry overnight. Apply a second layer of sealant in the same manner as the first one and let it dry overnight.
