Once grouting is complete, both types will need around 72 hours to start curing and up to a week to be fully cured. 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:

The first step is to clean between the tiles using a utility knife to remove any thin-set mortar left on the tile from outdoor tile installations. Step 2: Mix your groutOnce the floor has been cleaned and dried apply Tile Doctor Seal & Go sealer with a paint-pad applicator and tray. Spanish or Mexican terracotta tiles are very porous and may require up to 8 or 9 coats of sealant, always allow to dry before applying the next coat.

To do this, get a moist sponge and sponge frequently to clean the tiles without removing grout. Step 6: Grout the rest of the patio

Wet application: When the tiles are fixed using permeable bedding materials, ProPave can be applied using the “Wet Application” method. Thoroughly wet the patio surface with copious amounts of water. Using a stiff broom, brush sand into joints ensuring they are filled to capacity. Ensure the paving surface and sand are kept wet throughout the operation with continued use of gentle water flow from a hosepipe. This water aids deep penetration and compaction of the jointing sand as it drains. Repeat process until all jointing is filled to full depth. Soak the area with water & top up any joints that require further material and wash off excess sand from the surface.In most circumstances, a reclaimed floor is laid on a modern screed but sometimes it may be necessary or desirable to lay reclaimed tiles or quarry tiles on a limecrete floor. A solution of Grout Clean-up diluted with 3 parts water will ease the problem temporarily, but you will find in most cases the efflorescence will repeat itself until all the salt crystals have evaporated on the surface, and this can take several weeks in some instances. In worst case scenarios Tile Doctor has developed a new product calledAcid Gel to combat efflorescence issues which is applied neat. Recommended Products for Terracotta The other type of grout available for outdoor use is brush in grout. There are two different application methods for brush in grout: Dry application– This method is used to apply brush in grout where the bedding materials used to fix the tiling are impermeable and therefore will not allow drainage of application water or where the temperature conditions are dropping below 3°C, with concern that the water application (Wet Application) will freeze and expand in the joint, before it has drained away, making it weak. If using a cement-based grout: using a grout float, scoop up some grout, then deposit it onto the surface of the tile, spreading it over the tiles and grout joints.
