It was this point that my daughter dropped a pot on out porcelain tile at home and broke it. This got me wondering if my flooring plan would have to change.
I decided to scrap the porcelain tile I had picked out and go with a grout able vinyl tile.
Well this now meant that I needed to add another inch (backer board+tile+thinset) to my plywood. So break out the crew gun and add the extra plywood. At 1.75 inches of plywood this floor is REALLY sturdy.
Side bonus is that the slide now sits level on the floor and I can finally put the molding and roof on it..
1 piece aluminum roof, Same stuff I used on the main roof. vhb taped on and anchored by the face trim on the outside.
