Some weeks ago, I promised on request to show how to make the tile floors, since I was going to make one for Petit Brocante. I finally got there, and took some pictures of my work following the different steps of the work. Hope that makes sense, if not feel free to ask questions...
I use prints of real tiles, an I like them worn and un eaven..
I find the tiles on the internet, try google tiles (pictures of), or use this miniature link, where I found the tiles beneath. You have to copy and paste to make a page in word or another programme to print from..I use glossy photo paper.
Then glue the print to card board (1 mm). Remember to give your prints a layer of matte varnish to avoid the colors to smudge, and let dry. Next step is to cut out the tiles..
Then you have to make a copy of the ground or wall, you want covered, I used a light card board. Glue the tiles onto the card board. Let the glue dry under a light pressure from books or the like to make the surface even. Now to the grouting process..
I use real grout like the one you would use for the tiles in your bathroom. Don´t mix as much as I did on the above picture, I think there is enough for three floors at least ;-) I just add the grout with my fingers, maybe you want to use some kind of tool..
I use the sponge and some water (just a little) to wipe off the excessing grout. Be careful, just remove the most of it, and let dry the night over, you don´t want to ruin the "tile". The next day you can sweep the surface gently again. Then add a layer of matte varnish to seal the surface. And vupti!
...You´we got a real tile floor. But look closely (click to enlarge) at the last three pictures...I actually put too much grout between the tiles, you´ll get a much better result wiping a bit off, to get a little groove. I think this picture of one of my former floors shows this..
I hope you will have fun!
