How to Seal Porcelain Floor Tiles
How to Install
- When tiling you should use tile adhesive.
- Place at least 5mm thick glue on the floor using a tiling trowel.
- Add a thin layer of tile adhesive on the back of the tile.
- Twist the tile into the adhesive to rid it of trapped air
- Tap with a white rubber mallet (certain polished porcelain floor tiles may get permanently marked by black rubber mallets).
How to Grout
- Pre-packaged grouts are typically a good option, as their composition allows for improved mobility and flexibility.
- Pre-packaged grout should be cleaned up right away to prevent any stains and marking.
- Don’t add bonding liquids to the grout if it can’t be cleaned immediately and correctly.
- Only grout small areas at a time.
- Clean up any extra grout on the tile surface before the grout has dried.
- To clean tiles after grouting, add Stoneshield Grout-Lift™ to the water, followed by Stoneshield Deep-clean™ to neutralise the surface and ensure sealers continue working properly.
Reasons for Sealing Porcelain
High quality porcelain made in Europe doesn’t need to be sealed.
- Less wear

- Ease of cleaning
- Less static
- Prevents stains
Recommended Sealer

Stoneshield Porcelain Tile Sealer™: Specially formulated to protect porcelain tiles this solvent-based sealer penetrates the surface to repel dirt and make it easier to clean. The natural, no-sheen finish doesn’t leave a surface film ensuring your tiles keep their original look. The sealant may be applied to clean surfaces six hours before grouting as a pre-grouting sealant. Suitable for polished and unpolished porcelain tiles, as well as low porosity surfaces. Both indoor and external usage are appropriate.
Usage Guidelines
- Polished porcelain floor tiles often have a protective wax coating added during manufacturing. Before sealing, this should be completely removed with Stoneshield Wax-off™ or Stoneshield Xtreme-Clean™.
- To extend the lifespan of the porcelain tile sealer, only use Stoneshield Daily-Clean™. If the floor becomes hard to clean or starts to stain, reapply Stoneshield Porcelain Tile Sealer™.
- Sealers should not be applied to damp surfaces
- Ensure that grout and tile adhesive is completely dry before applying the sealant.
- After sealing, allow at least 24 hours before wetting tiles.
- For information on the appropriate drying periods, refer to the sealer label.
- If rain is predicted within 12 hours, avoid applying sealer outdoors.
