Option 1 - Butt Join
The panels have a flat edge and can be simply butted up to one another with silicone in the join. However, this does result in a visible line.
Option 2 – ‘H’ trim
‘H’ trim. An ‘H’ trim can be purchased from Reco or your local DIY or Tile store. This can be fitted behind the panels to cover the join. This does however mean that it looks a little less like real tiles.
Option 3 – Cut out
Cut out. The offset tile panels can be cut to join just like tiles. Using a handheld multi tool (like the picture) you can cut out every other tile and thus ensure the panels join like a jigsaw puzzle. If you do not have a handheld multi tool, then you can drill two holes in each corner of the tile to be cut out and then insert a Jigsaw cutter and remove the tile (the hole in the corner allows enough room for the blade to turn the corner). This is the best method to ensure the panels look like tiles.
