Drywall forms parts of most residential structures but can unfortunately be attacked by mold if exposed to water or moisture. Since water damage on drywall is inevitable, you can control mold damage by installing drywall that will resist mold in your home in areas likely to attract the growth of the fungi.
Consider the following factors when choosing drywall for different areas of your home:
Type of your space
Drywall is available in different forms. Gypsum-board is the most commonly used type of drywall and the one which many homeowners are familiar with. Gypsum-board is however not water-resistant. This board is therefore prone to moisture damage and eventually attracts mold growth. If you are worried about these damaging elements, then it would be better to invest in drywall that can resist moisture and mold. Such drywall will keep outside elements like moisture from finding a way into your interior space.
If you are still not sure on whether to choose regular drywall and moisture-resistant drywall, consider if the room you want to insulate is prone to water leakage or moisture damage. For instance, the kitchen and bathrooms are often exposed to moisture. Regular drywall may not be the best option for these areas.
Some rooms are more exposed to moisture than others which is a contributing factor to growth of mold. For instance, basement walls are cooler than those of other rooms of a house and moisture build up behind the walls may cause development of mold.
Sometimes vapor formed when we shower with hot water on a cold weather condenses and the moisture created slowly seeps in the porous walls of your bathroom walls and the rest of your home. Moist walls form a good environment to mold growth if something is not done about it.
Installing moisture resistant drywall in the bathroom can help prevent growth of mold. This type of drywall should however not be installed behind ceramic tiles.
If you are already using your finished attic, it could be exposed to mold growth at one time or another because of its proximity to the roof. The roof protects against snow or rain leakage in your attic which can be damaging if the space doesn’t have proper drywall insulation or if it has regular drywall that is not protective enough.
If you need to replace your drywall after water damage or mold issue, it would be a good idea to replace it with moisture-resistant drywall.
Cost of drywall
Regular drywall will not protect your property from water and mold damage. You will have to replace your cheap drywall if it’s exposed to moisture or mold. This is an expensive task that can be prevented by installing moisture-resistant drywall. This high-quality drywall is durable and eliminates the need for constant replacements.
Trying to apply paint over your regular drywall in the effort to seal away moisture is not worth. Moisture and minute mold spores can still penetrate through the painted drywall surface. This means that you will have to do some replacement when you have moisture problem or mold issues. To prevent these costly repairs and replacements, it would be better to install moisture resistant drywall from the very start.
