Grout Sealer seems very good but only time will tell. very easy to use and apply

By Peter Sheppard From Stockbridge

Great customer service. Grout magic easy to apply and v good colours.

By Helen Hartley

I've noticed a definite improvement and the sealant is certainly repelling most of the water if not absolutely all of it. It did take a few coats but that might be down to my tiles!

By Helen Green From London

Very happy with this it seems to have sealed the grout brilliantly, the water seem to just run off.

Superior Grout Sealer is a solvent free grout sealer that resists water, and oil based contaminants. Simplifies maintenance and does not change the appearance of the grout whilst allowing for moisture vapour transmission. It is used as a grout tile sealer for floor and wall tiles. As a grout protector it helps prevent mould and mildew on tiles in Bathrooms & Kitchens.

  • Works on cement based wall and floor porous grout joints for ceramic tile and natural tile installations
  • Can be used wall tiles and floor tiles in kitchens & showers
  • Effective for interior and exterior applications

Superior Grout Sealer works as an effective grout protector and is used in conjunction with other internal sealers and stone cleaners from Smartseal. If mould or mildew are present, use Mould and Mildew Remover first before the application of the Grout Sealer.

If you want to change the colour of existing grout use Grout Magic, an amazing grout restorer far superior to a grout paint or grout pens.

Directions for Use

  • Read entire label before using.
  • For new installations sealer can be applied 48 hours after grouting.
  • Use Grout Cleaner to ensure grout joints are clean, dry and free of existing sealers or coatings.
  • Use Grout Haze Remover to remove mortar or cement residue on tiles
  • Apply the Grout Sealer using a soft-bristle paint brush or sponge applicator.
  • Apply a second application, allowing a minimum of 30 minutes drying time between coats.
  • After 2 hours conduct a test to determine if surface is completely sealed by applying water droplets to the surface. If water is absorbed, apply an additional coat. Wait 2 hours and repeat the test.
  • Ready for surface traffic 2 hours after final coat. Sealed area should be kept dry for minimum of 12 hours. Achieves full cure in 24 hours.
  • Clean applicator tools with water after each use.
  • May be reapplied as needed to grout joints that are clean.

Always test a small area according to application instructions, with a 24-hour cure time to determine desired results.

LIMITATIONS: Do not allow sealer to dry on tile surface because a residue will be visible. Do not allow sealer to come in contact with any non-recommended surface. Sealer will not prevent surface wear from etching from acids or caustic chemicals.


Coverage rates

Approximately 15m2 to 60m2 per coat per 500ml, depending on porosity of grout joint and method of application. For example, on a 30 x 30 cm tile with a 3mm grout joint a 500ml bottle will cover approximately 40m2 for 2 coat application.

Expected Wear

Will vary depending on porosity and texture of surface, type of area, surface wear, frequency and type of maintenance products used. The expected wear is up to 5 years. Extreme weather conditions, harsh cleaning methods and high alkaline or solvent-based cleaners will affect the longevity and performance.
