Really ? I stand corrected . When ? <| sep |> Taking down a 2 lvl gym , 2 mins , maybe not even one revive . Countless times more efficient and time saving . <| sep |> Still , there are two huffpo articles on the front page . People will ignore anything as long as something agrees with them . <| sep |> There was a small leak behind my Grandparents toilet which no one was aware of until I was asked to find out why the cistern was doing small loud fills in the middle of the night . All the fittings in this bathroom appear to be mounted on Plywood , which has warped and is mouldy around the leak area . I pulled it up to assess the damage and deal with it . Properly installed and sealed it seems to be a decently water resistant and wear resistant option . Sealing it takes quite a bit of time as it absorbs a lot of sealant and requires 3 coats at a minimum , which is an expense that other options don ' t require . We used 4 coats of wood glue if I remember rightly , and each coat was several bottles worth . As it is so porous if you wear through the sealant or get it wet it takes a long time to dry out , and from pulling this lot up , it also makes an excellent home for mould .
