Preparing Drywall for Zinsser Mold Killing Primer
Assessing Mold on Drywall
To prepare for primer application, first evaluate the extent of mold on the drywall. Look for discoloration and a musty smell.
If the infestation is severe, it may require professional attention. Small patches of mold can usually be addressed with the primer.
Cleaning and Pre-treatment
Before applying primer, clean the affected drywall with a mold-killing cleaning solution. Scrub away any visible mold and allow the area to dry completely.
This step is crucial for the primer to work effectively.
Safety Gear and Ventilation
Ensure the room is well-ventilated to avoid inhaling fumes. Wear protective gear, such as gloves and a mask, to protect yourself from mold spores and chemicals during the cleaning and priming process.
Applying the Primer
Apply Zinsser Mold Killing Primer with a brush or roller evenly across the drywall. Cover the entire area, extending beyond the visible mold to ensure complete protection.

Best Practices for Zinsser Mold Killing Primer Application on Drywall
Application Techniques
For the best results, use a high-quality brush, roller, or sprayer to apply the primer. Each tool offers different advantages, but all should provide a smooth, even coat when used properly.
Make sure to overlap edges to prevent mold from sneaking through any gaps.
Coats and Drying Time
Follow the recommendations on the product label for the number of coats and the required drying time between applications.
Typically, one to two coats are sufficient, but this may vary depending on the severity of the mold issue and the porosity of the drywall.
Long-Term Mold Prevention
After applying the primer, take steps to prevent mold from returning. This includes controlling moisture levels, fixing leaks, and ensuring good air circulation in the room.
Regularly inspect the area for signs of mold and address them promptly.
