Drywall, despite all its advantages is prone to moisture damage. Well, at least standard drywall is. Since it is covered by paper on both sides, it is also extremely vulnerable to mold growth. Most homes which have a persistent moisture problem tends to have black mold growing on the drywall.
And its not easy to get rid of.
Superficial treatment methods rarely work because what you see on the exterior is just the fruiting part of the fungi. The actual root is underneath and spreads rapidly as the mold thrives on the enormous supply of food that drywalls provide.
While, its effects may not be immediately noticeable, mold growth can contribute to several health problems in the long run. This can mean frequent repairs and replacements for homeowners making it tedious and expensive.
How can one get rid of it permanently?
The solution is simple. Ask your drywall company about Mold Resistant Drywall instead of standard drywall.
Understanding Mold Resistant Drywall
Standard drywall is a gypsum panel that is covered by paper on both sides. And it has some percentage of moisture in it naturally.
This moisture alone is not sufficient to facilitate mold growth. However, expose it to the slightest level of external moisture and you have a recipe for unabated mold growth. The mold colonizes and spreads through the paper sheet extremely fast.
Mold resistant drywall on the other hand, is paper free. This prevents mold from having a readily available place to thrive. It is not waterproof but is very resistant to moisture and does not absorb moisture as readily as standard drywall.
Does it cost more than standard drywall?
At the point of purchase, it does. Not by much though. The few additional dollars that you pay for the mold resistant drywall will cost a lot lesser than what you’d pay for frequently removing and replacing damaged drywall.
If you have a home where moisture tends to be a long term problem, then it provides you with an added level of protection and also insures you against future damage which is inevitable if you use standard drywall. Most drywall companies will make this suggestion when you contact them for drywall installation.
Where can it be used?
You can use mold resistant drywall in places where the moisture level is higher than normal. Some examples are, the basement, the garage and the kitchen. There may be other areas of the home too where you can use it. If you have noticed condensation on the wall in your home, then those areas can be prone to mold and mildew.
Ensure that you have a properly sealed vapor barrier. Double check the insulation to help reduce the transfer of heat and the condensation.
So, irrespective of whether you are building your own home in a DIY project or are repairing a client’s home, you’d want to consider using mold resistant drywall wherever applicable. It will prevent costly call backs in future. Speak to the drywall company today to know more about prices.
