After the old floor has been dismantled, you need to check the humidity. She must have humidity no more than 4%. The humidity of the lag, boards and sound insulation gaskets should be no more than 12%. Floor boards, lining and lags for ceilings and floors must be treated with an antiseptic from the side and lower sides. It is very important not to coat the ends of the boards with an antiseptic, because this will lead to rotting.
