【Interior decoration Board material】On gypsum board moisture conditioning property
Hello, everyone！ We here are Office recovery and restoration Dot.Com. website personnel in charge.
This time, we think we are explaining a theme of moisture controlling property of gypsum board.
Previously, we wrote and uploaded an article of the difference depending on standard thickness of gypsum board materials（Japanese）.
This time, we are thinking of further digging into different phases of gypsum board.
As the board is situated as the ceiling or wall, you may usually do not recognize it with special consciousness.
However, it is an interior decorative material which is used most often presently.
So, we are glad if our following explanation will be of your reference.
Explaining basic features of gypsum board again
General purpose gypsum board reference picture(ceiling).
Usually after this, putty treatment will be done, painting and so-called decorative cloth finishing will be done.
At the present, gypsum board is the most popular and most used board material for interior decorative base material of ceiling・wall.
As material characteristic, the most pointed out features are, high incombustibility and high surface durability.
In addition, high sound insulating property can be also pointed out. So, it is used as almost all the present interior decorative board material.
Another feature of gypsum board【Moisture conditioning property】
Gypsum board has a feature of absorbing moisture in the air, and in the case of getting dry in the room, it gives off moisture.
Literally, its material is gypsum, and on its surface, special paper is rolled up. So, as for moisture conditioning property, it can be said that it is a feature of gypsum itself.
However, as there are some points to be noted to make use of its moisture conditioning property too, so we are going on mentioning them later.
Points to be noted to make use of gypsum board moisture conditioning property
Although gypsum board is a board material with high moisture conditioning property, it is considered that we should prevent from using it at the building outside where moisture is directly splashed, such as bathroom, around sink, and so on.
Gypsum board can absorb moisture to a certain degree. However, if it exceeds allowance level, its strength will be deteriorated, and becomes fragile.
Especially if rain leakage or so touching water on the board material frequently happens, there is high probability of opening holes on it.
Likewise, you should be also careful of mould. As very humid places cannot easily discharge moisture which gypsum board contains, mould may grow.
When finishing by so-called decorative cloth or painting, in the case of executing construction work which may lead to deteriorating moisture conditioning property, you should be especially careful.
Generally speaking, vinyl cloth can be easily finished wall neatly after executing construction work with gypsum board. But, it often happens to deteriorate moisture conditioning property.
When painting too, as paint coating is done, it is necessary to be careful.
At the places where dew drop easily occurs, or where it happens violent temperature change or so, it is necessary to take countermeasures such as changing finishing into using high moisture conditioning property so-called decorative cloth, painting or plasterer finishing, switching on dehumidifier, fully ventilating air, or so.
How to execute construction work with higher moisture conditioning property
As gypsum board also has various plural kinds, it may be effective to also use one with higher moisture conditioning property.
Yoshino Gypsum Co.,Ltd., Japan product『Tiger High Clean Scatboard』, Chiyoda Ute Co., Japan product『Sawayaka gypsum board』and so on are a certain kind of gypsum board added high moisture absorption and desorption property material.
『Sawayaka gypsum board』is a product added gypsum with kieselguhr(phytoplankton fossil. It is porous, and high moisture absorption and desorption property and sound insulating property.), so moisture absorption and desorption property is enhanced.
Kieselguhr is also used for plasterer finishing painting wall.
Plaster finishing by kieselguhr is effective same as above-mentioned functional gypsum board. By further combining together, it is also possible to enhance its effectiveness.

As to so-called decorative cloth, we already introduced, which tends to impede moisture condioning property of gypsum board previously, highly moisture absorption and desorption property so-called decorative cloth also exists recently.
As to so-called decorative cloth, many producers sell so-called decorative cloth with various functionalities. Water absorption polymer (used for paper diaper, cold reserving gel and so on) and above-mentioned kieselguhr and so on various materials are helping moisture absorption and desorption property of gypsum board, and enhancing it or adding air permeability.
In this way, there are various methods to enhance moisture conditioning property of gypsum board itself.
As there are appearance or compatibility of effectiveness, please talk with us construction work contractors for details.
We so far explained moisture conditioning property of gypsum board this time.
Not only gypsum board, interior decorative materials are steadily progressing, and the function has been improving step by step.
If you are considering to re-stick gypsum board in order to repair a whole wall or generally, we suggest you to call back points in our article this time as much as possible.
Not limited to moisture conditioning, if you happen to have other request such as quotation of construction work, we are happy to propose our reply on request.
Brief summary as follows,
・Gypsum board has moisture conditioning property, and it absorbs・desorbs water in the air according to the humidity.
・However, there is possibility of impeding moisture conditioning property of normal vinyl cloth or paint finishing or so.
・As to gypsum board moisture conditioning property, it is possible to further enhance it by using moisture conditioning property added gypsum board or executing plasterer finishing with kieselguhr or so.
By executing with gypsum board or each utilizing plural properties which other board materials have, various place construction work of interior decoration is possible.
When newly executing partition wall construction, we suggest you to clarify which place and what kind of usage you need to use, and talk with us.
