My track edge is going to be red and white tiles with the red tiles slightly taller.  I used the left over stip I cut from the last step to make the red tiles.  I made them double in length of their height.  I cut one extra to use as a spacer between them when I glue them down, so they will be even. 

The bottom strip will be the white tiles.  I wanted the ends of the strip to be white tiles so it would be as flush as possible when mounting the board back in the frame.  This also worked to cover the seam with a top tile that we had when we glued the strip together.  I then painted the top tiles Tamiya flat red.

I used a brush and made sure my final coats of paint were brushed from top to bottom.  I figured this might help give the impression of the direction water would travel if it rained on the tiles.  I saw in several pics some pristine tiles and some really beat up ones.  I'm keeping it simple.

When the paint was finished on the red tiles I clamped them to the white strip using my spare tile as a spacer.  Then I hit that bad boy with some thin Tamiya cement.
