Customer Questions & Answers

  • Question: What is Dicor 501LSW-1 sealant used for?

    Answer: Dicor 501LSW-1 sealant is primarily designed for use on horizontal surfaces in RV roofing applications. It serves as a self-leveling lap sealant that adheres to various materials, ensuring a watertight seal. This is particularly important for RV maintenance and repairs, as it helps prevent leaks and water damage, especially during rainy seasons or when traveling through wet conditions.
  • Question: How does the self-leveling feature of Dicor 501LSW-1 work?

    Answer: The self-leveling feature of Dicor 501LSW-1 allows the sealant to spread out evenly when applied, filling gaps and creating a level surface. This characteristic is crucial for horizontal installations, as it ensures optimal coverage without requiring excessive manipulation. This not only improves the aesthetic of your RV but also enhances functional integrity by creating a strong barrier against moisture.
  • Question: Is Dicor 501LSW-1 safe for use on all types of RV roofing materials?

    Answer: Yes, Dicor 501LSW-1 is formulated to be compatible with most common RV roofing materials, including rubber, metal, and fiberglass. This versatility makes it an excellent choice for various repair scenarios. However, it is always advisable to clean the surface thoroughly before application to ensure optimal adhesion and effectiveness.
  • Question: Can Dicor 501LSW-1 be painted over?

    Answer: Dicor 501LSW-1 sealant is designed for exposure to the elements and can be painted over with compatible exterior paints once it fully cures. This is particularly beneficial for those who want to match the sealant to the color of their RV. Be sure to check the manufacturer’s instructions for paint compatibility to ensure the best results and longevity.
  • Question: How do I apply Dicor 501LSW-1 sealant?

    Answer: To apply Dicor 501LSW-1 sealant, ensure the surface is clean, dry, and free from debris. Using a caulking gun, apply a consistent bead of sealant along the seams or areas needing repair. The self-leveling property will help it spread out and fill any gaps. Allow it proper curing time as indicated in the instructions for optimal performance.
  • Question: What is the drying time for Dicor 501LSW-1?

    Answer: Dicor 501LSW-1 typically dries to the touch within a few hours; however, complete curing can take up to several days, depending on environmental conditions like humidity and temperature. Proper drying is essential to guarantee the effectiveness of the seal. It's best to allow it to cure fully before exposing it to any moisture or strain.
  • Question: Is Dicor 501LSW-1 environmentally friendly?

    Answer: Yes, Dicor 501LSW-1 is HAPS-free, meaning it does not contain hazardous air pollutants.
