Painting alone is unlikely to completely eliminate the smell of cat urine. The odor from cat urine is strong and persistent because it contains compounds like uric acid, which can penetrate deep into surfaces such as wood, drywall, and concrete. Simply painting over these areas may temporarily mask the smell, but it won’t address the underlying issue, and the odor can eventually seep through the new paint.
Steps to Properly Address Cat Urine Smell Before Painting
- Thorough Cleaning:
- Before painting, clean the affected area thoroughly using an enzymatic cleaner designed specifically for pet urine. These cleaners break down the uric acid in the urine, which is responsible for the lingering smell. Make sure to follow the instructions on the cleaner to ensure it’s used effectively.
- For surfaces like wood or concrete, you might need to scrub the area with a stiff brush to help the cleaner penetrate deeply.
- Stain and Odor Blocking Primer:
- After cleaning, apply a stain and odor-blocking primer to the area. Products like Kilz or Zinsser B-I-N are designed to seal in odors and prevent them from seeping through the paint. These primers can create a barrier that locks in the smell and any remaining stains.
- Make sure the area is completely dry before applying the primer to ensure it adheres properly.
- Painting:
- Once the primer has dried, you can proceed with painting. The paint will provide an additional layer of protection, but it’s the primer that does the heavy lifting when it comes to sealing in odors.
Important Considerations
- Identify All Affected Areas: Cat urine can soak into floors, walls, and even baseboards. Be thorough in identifying all areas that need treatment.
- Ventilation: Ensure the area is well-ventilated during the cleaning, priming, and painting process to help dissipate any fumes and aid in drying.
- Replacement as a Last Resort: In extreme cases, if the urine has deeply penetrated porous materials like carpet, padding, or subflooring, it may be necessary to replace these materials to fully eliminate the odor.
Conclusion
Painting can help in dealing with cat urine smell, but it’s crucial to first treat the area with enzymatic cleaners and a stain and odor-blocking primer. By properly cleaning and sealing the area before painting, you have a much better chance of eliminating the odor permanently.
