The first rule of drywall is always to keep the wall dry.
But there are times when a drywall’s resistance to moisture is so great that you may want to consider its use in the building.
For example, a dry wall made of glass is much less likely to shatter if it is punctured, and the ability to maintain a low water table can make it much easier to treat.
But drywall that’s been treated with a water-repellent is less likely or harder to remove.
The second rule of drying is to use it when it is necessary.
Drywall that is too hard for the job or is not durable enough to withstand a load of weight is likely to crumble.
And in a building where water is an issue, a wall that has a low ceiling might not be an option.
The drywall you use will be the same drywall used in other rooms and the same damp wall you would use in your office.
Drywall resistance also matters in terms of its longevity.
As drywall gets stronger, it can withstand longer periods of drying and then will need to be replaced.
And it is often not the case that a dry-walled building will become too strong to hold its own against water damage.
The third rule of wetwall is to not treat it.
You can always get rid of dry wall, but it will need the use of a high-grade drywall.
The fourth rule of water-resistant drywall applies to all types of dry-drying.
In general, water-resistive drywall does not require any special treatment to prevent the spread of water and the addition of chemicals, such as water-based dewax or dehumidifiers.
It’s just a good idea to treat it properly.
