A drywall is a central panel of gypsum and is applied with both additives and without it and consists of thick sheets of facer and backer paper, which is used for the construction for interior ceilings and the walls. This mixture is mainly mixed with a lot of things such as fiberglass, asbestos sheets, and various other additives which add more properties such as water absorption, reduction in mildew, and many more things. This type of construction became common in Northern America because of its time and labor-saving procedure. This also helps in replacing the traditional lath and plaster and also drywall repair and installation is easier to do.
Drywall is strong in its own right. A panel of drywall is sandwiched between paper and heating. Drywall being the material named gypsum, it is heated until it is made into a plaster-like mixture and it is mixed with various additives such as starch, fiberglass, plasticizer, and other additives to increase the fire resistance and also use an additive named silane for the lesser rate of water absorption. Then, the wall is made by sticking together the mixture between two sheets of fiberglass mat and is set to dry. This increases the rigidity of the material, which then becomes strong enough to be used as a material for construction.
Techniques applied for construction:
A typical drywall construction usually only takes up to 2 days to be installed by professional dry Wallers as compared to the week-long procedure taken for plaster application. Drywall can be finished from in the most natural method, where the drywall is installed in without being exposed to the elements or any wear and tear, even though it is thoroughly recommended to the drywall to be painted and applied primer to it to avoid any corrosion. Doing this could make sure that there isn’t any further damage which may result in drywall repair or installation of new drywall.
Common features of drywall:
- Sound Proofing:
Drywall, since it is mixed with several materials, can also be mixed with materials which reduce the noise. Multiple layers of drywall are recommended to thicken the drywall, which, in the case, helps in dampening the sound.
- Damage caused by water:
Due to being mixed with materials which sometimes absorb water, this could result in the drywall to soften the sheet, which it turns into a mushy mixture and it will start peeling off. Not only that, these could serve as a breeding ground for bacteria and other fungi. If left for no good, termites could take over these walls, which could result in the drywall breaking down. Hence, the usage of drywall is not recommended for places which are continuously exposed to water and humidity such as the kitchen, bathrooms as such. To avoid several drywall installations, which could result in more expenses, it is advised to plan the places where the panels are not exposed directly.
- Resistance to fire:
Since the drywall is made using gypsum, these walls are 50 percent water in turns of volume. Therefore, when these panels are subjected to fire, the heat of the fire is absorbed and is given out as steam. There are separate drywalls known as “Type X” board which has passed the standard test for fire resistance and materials such as boric acid, perlite is used to increase fire resistance.
- Waste materials:
It has been noted that almost 12 percent of drywall is being wasted during the drywall installation. Not only during installation, but there is also a notion of drywall being wasted after manufacturing. Since drywall is gypsum and other chemically enhanced materials, it is banned in certain dump yards. Because of these reasons, the manufacturers are required to take the used drywall which was used and thrown during drywall installation and recycle it.
How to do drywall repair and installation:
There might be instances where the drywall has gone through some minor damages such as holes and other things which do not require the services of a carpenter, and it seems to easy enough to be done by a small DIY (do it yourself).
- In case of small holes', the size of a doorknob, a patch kit can be used to fill the hole. A patch kit8 contains a self-adhesive patch of mesh which can be stuck on the hole directly on top of the hole.
- Then, the person has to use the drywall knife to apply a compound in a criss-cross pattern over the mesh panel and let the space dry.
- After the first layer has been left to dry, apply the second layer of compound and then smoothen out the surface. The drywall is strong and if needed, ready to be sanded to perfection.
- In case of larger holes, a spare piece of drywall needs to be cut down according to the required measurements.
- Add a furring strip and sink the screws beneath the surface of the drywall.
- Set the drywall patch and screw it in place.
- Apply an adhesive mesh patch and then apply the compound.
- Then apply a second layer of compound and smoothen out the irregularities.
Installation of Drywall:
- Make appropriate measurements of the wall where the drywall has to be installed.
- Cut off excessive drywall without the tearing the paper backing. Then slowly cut off the paper according to the requirements.
- Apply the adhesive and apply the drywall on them. Press for few seconds to lock it in place.
- Apply the required number of screws to install the drywall permanently.
- Cut out the drywall for required outlets.
- Finish the process by applying at least two coats of compound and by ironing out the irregularities.
- In this way, any drywall repair and installation can be done without the hassle of spending any money than the ones required for the purchase of materials.
