These tiles are generally made in a factory with some artizan involvement however the quality of the kiln is far better than Mexican and so are easier toclean, to seal and to maintain; naturally thisresults ina higher productioncost. Wet application– When the tiles are fixed using permeable bedding materials, brush in grout can be applied using the “Wet Application”

Again this only really applies to cement-based grout. Using a sponge, you can seal the grout using an outdoor-rated grout sealer. Final Thoughts Two main types of grout are applicable for outdoor use. The first is the standard cement-based grout, and the second is the brush in grout. Below are some of the pros and cons of both, which will help weigh up what is best for you. Rated for outdoor use Cement-based grout comes in powder form, which is added to water before being applied. The most common type of outdoor grout is sanded grout. This is used when grout joints are 1/8 inch or wider. Both types of grout ideally require tile surface temperatures of at least 10 degrees Celsius and no more than 40 degrees Celsius.It neutralises any alkaline salts inherent in the floor thus preventing the build-up of Efflorescence which can be a problem with older floors. Once a good seal is achieved leave the sealer to cure for a minimum of 12 hours to cure, before applying the Ironwax Satin/Gloss. For best results, the sealer should be applied after the tiles have been laid but prior to grouting. This means that not only are the tiles easier to grout but also the tile ceases to be porous and the grout will not penetrate the surface of the tile. Once the tiles are grouted, a second application should be made. The reasons for this are twofold:

Once the Mattstone sealer has been allowed to fully cure (12 hours), apply 2 coats of Ironwax Satin/Gloss with an hour between coats. Then allow 4 hours for the finish to cure before starting the grouting process using Ardex FL grout. If the tiler is not using our recommended Ardex FL grout, then please test your chosen grout on the surface of a sample tile, to ensure the grout can be cleaned away successfully. For stubborn areas of heavy build-up of dirt or sealer we would recommend following up with NanoTech HBU (please ensure the tile is wetted before applying).

Why Is Grouting Important For An Outdoor Patio?

If the grout joints are less wide than this, then unsanded grout is fine. The grout must also be rated for no efflorescence. This makes sure that white residue isn’t formed when moisture is lost.
