I have a 20x28 space i am thinking about doing racedeck in, a 1/4-1/2" gap is advised on the 20' sides (the long side wont be close to a wall on either side)... So 28 tiles wide would be too wide and 27 would be way short.... Do people cut the tiles down on one side by an inch? I.e cut the 28th tile to leave a gap? Also what about the male pieces sticking out one one side?
