Unfortunately, these chemicals are potentially toxic which can cause serious health concerns. So, with that said, to be safe, it is a really good idea to remove it.

Step #1 Determine the dimensions of the inside of the shipping container
Step #2 Purchase the lumber needed to completely fill the space where the old wood is being removed
Step #3 Using a circular saw begin making several cuts into the wood flooring to make it easier to remove the wood
Step #4 Using a long, sturdy pry bar to start removing sections of the wood on the floor
Step #5 Once all of the wood is removed, begin measuring the new boards to be used for the replacement flooring

Encapsulate the underlayment with a new subfloor and tile over it

An alternative to replacing the treated wood typically used in the flooring of shipping containers is to totally encapsulate the old flooring. By doing this you completely eliminate the concern of the exposure to any of toxic chemicals typically used as wood treatment. This is done by first completely covering the existing flooring with a layer of marine plywood. Then cover the underlayment with a ceramic tile.

Step #1 Determine the actual measurement of the inside of the container to figure out how much marine plywood you need – each sheet is 4’ x 8’
Step #2 Mark the sheets of plywood so that you can cut them with a circular saw
Step #3 Once you have each piece of plywood cut, apply a liberal amount of adhesive to the back of the board and place it snugly against the wall.
Step #4 Repeat with the remaining boards until the floor is completely covered
Step #5 After selecting what tile you want, put down a liberal amount of thinset (adhesive)
Step #6 Apply a coat of thinset to the back of the tile and place it on the floor and tamp it down until it is level
Step #7 Place a plastic spacer on each edge of the tile
Step #8 Repeat steps #5, 6, and 7, let set overnight
Step #9 Apply the grout to all of the edges of the tile
Step #10 Using a dampened sponge wipe the excess group from the tile and let set
