This durability means it is less likely to need frequent reapplication, which is a definite plus for long-term maintenance. Additionally, it offers excellent coverage, with a pint covering up to 500 square feet, making it cost-effective for large areas. Its ease of application is another strong point, with users finding it simple to apply without requiring professional help.

Another benefit is its certification for indoor air quality (SCS Certified INDOOR ADVANTAGE GOLD), indicating it meets strict standards for low emissions of volatile organic compounds (VOCs). This is a significant advantage for users looking for a safer option indoors. The product dimensions and weight suggest it is compact and easy to handle during application.
