Using Kilz primer on the subfloor surfaces can be an effective step in helping to seal and block the pet urine odor. Kilz is a brand of primer that is specifically designed to cover and block stains, including odors like those from pet urine. It has properties that can help lock in and neutralize the smell, preventing it from permeating through the new flooring you plan to install.
Here's what you can do to address the pet urine odor issue:
Clean the Subfloor Thoroughly: Before applying any primer, ensure that the subfloor is thoroughly cleaned to remove any urine residues. Use appropriate cleaning agents to break down and eliminate the odor-causing elements. Allow the subfloor to dry completely before proceeding.
Choose the Right Kilz Primer: There are different types of Kilz primer available, so make sure to select one that specifically mentions its effectiveness against odors and stains. Kilz Original or Kilz Max are examples of Kilz products that are designed to address strong odors.
Ventilate the Area: Ensure proper ventilation in the space while applying the primer to allow any fumes to dissipate. Use a mask and follow safety guidelines during the application process.
Apply Kilz Primer: Follow the manufacturer's instructions for applying the Kilz primer. Typically, you can use a brush or a roller to apply a thin, even coat over the subfloor surface. Allow the primer to dry thoroughly as per the manufacturer's recommendations.
Choose Suitable Flooring: After applying the primer and allowing it to dry, you can install your preferred flooring option on top. Kilz should not adversely affect most flooring types, but it's essential to check the primer's compatibility with your chosen flooring material. In general, it should work well with various types of flooring, including carpet, hardwood, laminate, vinyl, and ceramic tiles.
Monitor for Odor: While Kilz is effective in many cases, very strong and deeply embedded odors may still require additional treatments or, in extreme cases, replacement of affected subfloor sections.
Keep in mind that while Kilz primer can be an effective solution, severe and persistent pet urine odor issues might require professional help, especially if the urine has penetrated deeply into the subfloor. Consulting with a flooring specialist or contractor who has experience dealing with pet urine odor problems can provide valuable insights and recommendations for your specific situation.
