Customer Questions & Answers

  • Question: What is RadonSeal Standard Concrete Sealer used for?

    Answer: RadonSeal Standard Concrete Sealer is designed to penetrate deeply into concrete surfaces to provide effective waterproofing and radon mitigation. It is particularly useful for basements and foundations where moisture and radon gas can be problematic. By sealing the pores of the concrete, it helps prevent water infiltration and reduces radon levels in your home, creating a safer living environment.
  • Question: How do I apply RadonSeal Standard Deep-Penetrating Concrete Sealer?

    Answer: To apply RadonSeal, first prepare the concrete surface by cleaning it thoroughly to remove any dirt, debris, or previous sealers. Then, you can use a sprayer, roller, or brush to evenly apply the sealer, ensuring it saturates the concrete adequately. Typically, two coats are recommended for optimal results. This method effectively creates a barrier against moisture and radon, making it ideal for homeowners looking to improve indoor air quality and waterproof their basements.
  • Question: Can RadonSeal be used on exterior surfaces?

    Answer: Yes, RadonSeal can be applied to exterior concrete surfaces but is primarily formulated for indoor use, particularly in basements. When applied outdoors, ensure the climate is suitable for curing. The deep-penetrating properties help protect against moisture and mitigate radon, even on exterior foundations. This can be an excellent choice for buildings that are above ground but still require protection from concrete moisture intrusion.
  • Question: How long does RadonSeal take to dry after application?

    Answer: RadonSeal typically dries to the touch within 1 to 2 hours under ideal conditions. However, full curing can take up to 24-48 hours before the surface can be safely inhabited or covered. It's important to ensure proper ventilation during the drying process. Knowing the drying time can help you plan any further construction or finishing work needed in your basement or on the concrete surface.
  • Question: Is RadonSeal environmentally friendly?

    Answer: RadonSeal is formulated to be environmentally friendly, containing low VOCs, which minimizes air pollution and harmful emissions during application. This makes it a responsible choice for homeowners concerned about indoor air quality. Using an eco-friendly sealer not only protects your home but also contributes to a healthier environment, making it suitable for residential applications.
  • Question: What are the benefits of using RadonSeal for radon mitigation?

    Answer: RadonSeal provides a substantial reduction in radon levels by sealing the porous structures in concrete. This limit on gas entry enhances indoor air quality, which is critical for health due to radon being a radioactive gas linked to lung cancer. Implementing RadonSeal as part of a radon mitigation strategy effectively fortifies your living spaces against contamination, especially in areas known for high radon levels.
  • Question: Can I use RadonSeal on old concrete?

    Answer: Absolutely! RadonSeal works effectively on both new and old concrete surfaces. For older concrete, proper cleaning and surface preparation are crucial for achieving optimal penetration and sealing efficacy. Repairing any visible cracks beforehand can further enhance the performance, making it a great solution for updating and reinforcing the durability of aging structures.
  • Question: How does RadonSeal compare to other concrete sealers?

    Answer: RadonSeal differs from many traditional concrete sealers by offering deep penetration and protective features that target radon mitigation alongside waterproofing. Unlike surface sealers that create a film, RadonSeal penetrates into the concrete to form a barrier at a molecular level, providing more long-lasting results. This dual-functionality makes it a superior choice for homeowners prioritizing both moisture control and health safety.
  • Question: Is there a specific temperature range for applying RadonSeal?

    Answer: Yes, RadonSeal should ideally be applied when temperatures are between 40°F and 90°F (4°C to 32°C) for optimal adhesion and curing. Extreme temperatures can affect the application and performance of the sealer. Performing application in suitable conditions ensures the best performance and longevity of the seal, giving you peace of mind regarding your basement's waterproofing and radon mitigation.
