Let me ask you another question why do you even need a wetness retarder or a wetness barrier in the wood floor setup?
The response is very simple: hardwood flooring concerns your house and has a moisture or relative wetness of 6 % to 9 % optimum. Brand-new building has a relative wetness much higher as high as 25 %, due to the many products simply presented to the the construction that relate to water: plaster, paint, new wood, plywood, concrete in the basement.like it explains here how to repair engineered flooring?
A wetness barrier, or retarder has the function of slowing the absorption of wetness to the new wood flooring. If the wood floor absorbs moisture too quickly it will trigger it to broaden in a extremely abnormal way leading to cupping.
Which underlayment is finest matched to retard moisture absorption in a brand-new wood flooring installment?
As I was saying before the two main materials offered to installers are rosin paper, and 15 pound felt roofing paper.
Wood installers usually utilized rosin paper, that pinkish paper utilized as an underlayment. Does rosin paper have any wetness retardant on wetness obstacle properties? Not.
In the old days rosin paper was utilized mostly as the dust barrier. That’s why they use rosin paper as the dust retarder even more than a wetness retarder. We always presumed installers are experts and understand why they make use of rosin paper.
More recently I saw installers utilizing 15 pound felt roofing paper as an underlayment. Initially it seemeed a counterintuitive kind of move. Roof paper as a flooring? I explored it in more depth and I truly see the value of making use of roof paper as an underlayment. Wetness is not caught is permitted to travel through but at a extremely slow rate, for that reason it does not bring about cupping, it will not lead the wood to an unnatural expansion.

Will you overlap the joints in felt paper? it depends on you, however if you use 30 pound felt you will just butt the joints.
Exactly what about Visqueen or plastic as a wetness barrier under wood flooring?
The use of plastic of Visqueen is never suitable. It will trap moisture and will not permit moisture to travel through therefore creating the right situation for the development of mold.
