Apply a thin layer of the cementitious adhesive to the entire hob using the flat side of the trowel. Beginning at the inside of the hob wall, comb a thicker layer of the adhesive on the entire hob with a notched trowel. Hold the trowel at a right angle and continue applying adhesive to the top of the hob wall, and then to the outside of the hob wall.
Lay the hob tiles onto the adhesive within 30 to 45 minutes of the adhesive application. Firmly press the hob tiles onto the adhesive and tap each tile in with a rubber mallet to avoid air pockets. Begin laying tiles on the inside of the hob wall, then the outside and then the top of the wall. Cut tiles to size with tile cutter when necessary. Scrape off any dried adhesive with a trowel if a dry skin begins to form, then apply more adhesive and continue laying hob tiles.
Let dry for 15 minutes, then remove any damp adhesive on the tile face with a warm damp towel and soapy water. Remove any dried adhesive with mineral oil or adhesive remover. Let the adhesive dry completely following the manufacturer's instructions before grouting the hob.
Grout the tiles using a flexible pre-mixed and water resistant grout. Apply grout with the side of a rubber float. Start at the inside wall of the hob, then grout over the top of the hob to the outside wall of the hob. Wait 20 minutes, then wipe the grout off the surface with a damp sponge. Allow grout to set and dry following manufacturer's instructions.
