So the marks are put around the words “tile work” because this is 100% paint.  Not real tile.  Several years ago I worked in a set dept. that did all kinds of sets for plays, movies, events and industries.  The joke when i worked there was the bossman would hand us a piece of wood and say “make this look like metal”, then turn around 30 minutes later, hand us a piece of metal and say “make this look like wooD”!   It was a very cool school/job.  I can pretty much make anything look like anything….a handy skill to have.  Check it out;
