Note: For large moldy drywall jobs, we recommend that you contact a mold remediation professional to ensure the moldy sheetrock is properly removed to avoid cross contamination. They can also ensure the water leak or condensation source is identified and fixed. Use our online mold remediation contractor directory to find a water damage mold remediation professional in your area.
This video suggests the following DIY moldy drywall removal steps. Our editorial comments are identified by the orange triangle exclamation points.
First turn off your heat or air conditioning and close/seal vents in the damaged room. Close or seal doorways, too. Mold spores will get airborne when removing mold damaged sheetrock. So sealing the room is important.
For maximum safety, professionals will tell you to use a fan to vent air in the room directly to the outside of the home.
Professionals will also tell you to use an industrial HEPA filter vacuum on the mold damaged surfaces to prevent mold spores from getting airborn during the moldy drywall removal process. We suggest using our Endurance BioBarrier Mold Prevention Spray on these moldy surfaces before removing. Let the spray penetrate for 24 hours to eliminate the mold spores.
Protect yourself against mold allergy symptoms by using a P100 mask, rubber gloves, goggles, and a body suit.
After removing water and mold damaged drywall, be sure to check for mold that may have spread to the insulation and studs, plus the opposite side drywall behind the insulation. You may need to remove moldy insulation and the drywall on opposite side behind the insulation.
If it is only light surface mold on the studs and drywall behind the insulation, you may be able to simply remove the mold with a biocide designed to kill mold.
Please note that at 4:45 in the video, he recommends a competitor’s mold product. Unfortunately, if you read the label on this popular product, the manufacturer specifically states that the product must be re-applied if exposed to moisture. Re-applying would certainly be tough to do in enclosed wall cavities if condensation or water issues re-occur.
Don’t forget to fix the original moisture problem that contributed to the black mold problem.
Since it is very likely that recently cleaned studs and drywall will be slightly damp when you are ready to install the new drywall, don’t risk mold regrowing inside your walls after you cover up your repair project. Use our non-toxic Endurance BioBarrier Mold Prevention Spray on all damp and dry surfaces including insulation. You should even use a fogger or fine mist hand pump sprayer to get it into partially enclosed inaccessible cavities. And in HVAC ducts as well since they likely already have mold spores in them. Don’t risk future hidden mold problems!
