Sweep off the porch, and then use a hose to clean it off further. Let the porch dry for a couple days.
Mix up some thinset mortar in a bucket. Follow the directions on the package. Place some mortar on the porch with a notched trowel, beginning in a corner.
Turn the trowel at an angle and spread the thinset. Only put down enough for a few brick-looking tile pavers.
Place a couple of the brick-looking tiles down on the mortar. Put spacers in between the tiles to keep them apart. Repeat the process to finish the first row of brick-looking tiles.
Start the second row the same as the first, and continue until you have covered the entire porch. Remove the spacers from the previous row as you lay down the next, and use them in the current row you are installing.
Cut tiles if needed with a wet saw and a masonry blade. Measure the space where the brick-like tile needs to fit, and transfer the measurement to the tile. Cut the tile along the mark.
Let the tiles set up for 24 hours.
Mix up more thinset mortar and put it in a brick grout bag. Place the tip next to the gaps between the brick tiles, and squeeze the bag like an icing bag. Move the bag along the gaps as you squeeze. Scrape the mortar down with a trowel. Wipe off any excess mortar that covers the tile edges, so that it does not dry on the surface. Use a damp rag to wipe the tiles. Let the surface dry for two days.
