Mold And Drywall

Mold is sneaky. It can get in even in the most inaccessible places of your home because mold spores are everywhere.

Things to consider when choosing materials

An expensive material isn’t necessarily the best one for the job. You have to consider several factors when you’re choosing a mold-resistant drywall for your home.

First, consider your location. Then, check your material’s compatibility with your home’s weather — whether it’s humid or not.

Another factor you ought to consider is how the overall system drains and dries. Despite choosing a mold-resistant material, you still need to follow mold prevention measures. 


Tips for mold prevention

One of the basic mold prevention measures is preventing leaks. A way to protect your home from unwanted leaks is by maintaining your roof.

Your roof is the first form of defense against the harsh elements, and they’re subject to water damage and mold growth. Hence, you have to be sure to check your roof before and after a big storm.

Another tip is to seal your windows. Your windows’ caulks are subjected to the weather as well; it’s essential to give them attention as well.

If your window seals are broken, outside water either from the rain or gutter may get inside. This would affect both your windows and adjacent walls. 

Later on, these forms of water damage would lead to mold contamination. So, it’s important to remember these protective measures. 


The Best Mold-Resistant Drywall

Right now, the best mold-resistant drywall should have a non-paper-faced gypsum wallboard. That, or you can pick drywall with a water-resistant fiberglass gypsum panel or wallboard.

Those characteristics mentioned above would protect your drywall from mold and moisture compared to a regular one with paper. The advantage of regular drywall is that it is light, but the paper can serve as a food source to mold.

If you have trouble choosing between non-paper-faced or fiberglass, we recommend the latter. Fiberglass doesn’t have any organic material that may serve as a food source for mold.

A word of caution

Using such materials would lessen your chances of mold contamination, but it won’t entirely prevent it. You still need to be responsible and familiarize yourself with mold prevention procedures.

For additional protection, use other mold-resistant materials aside from drywall. Although, make sure that the ones you use are compatible with each other.

The installation for mold-resistant drywall is similar to the standard one. First, the drywall panels are nailed on the framing.

Then, you have to cover the joints between the panels with drywall tape. After covering it, coat the joints with several types with a taping compound.

Make sure to sand the surface after each coat. After installing the drywall panels, nail the trim and the baseboards on the installed boards.

Afterward, paint and finish the surface using a wall primer and mold-resistant paint.
