Over the past week me, my mom, my mom's boyfriend, and my grandpa (that is now indisposed from this...heat exaustion

) decided to take the time to replace the 35 year old linoleum flooring in the kitchen. We ripped that out, then found that the sub floor had been rotten and had holes in it.
Well, being my grandpa, he gave us some chipboard and we spent a day to lay that down and another to paint it for our new tile.
Now it's down, but look at how the directions on the tile boxes conclude the whole process.
