im replacing my subfloor in a mobile home in 3 of the rooms right now does it matter which side (smooth or roof) i should face up. ive been putting the rough side up because the smooth side seemed as if it had maybe a moisture barrier on it and i figured since it did it would be best facing the outside of the floor and im covering this floor with sheet vinyl anyway, since its rough i thought maybe the glue would adhere better too so does it matter and if it does ive already installed 7 sheets this way will it hurt anything in the long run??
