Not sure it is the best choice for a clean leak free sealant.
3 out of 5 stars
Not sure it is the best choice for a clean leak free sealant.
This is the recommend sealant for RV skylights. My understanding is if Dicor self-leveling sealant makes contact with the skylight the plastic material would be damaged. So I went along with using Surebond. What I do know, it does not appears to hold up on the roof and it does not self level. This was applied in April 2021. Already separating from edge of skylight.

    The right sealant for the job! It works well but is very hard to work with as far as sealants go. It is very sticky and can't be tooled or smoothed with finger. When you apply it, do so with caution and finesse as the way it comes out the tube is the way it will stay!
  • Reviewed in the United States on January 6, 2025
    Durable and easy to apply, but remember, this is a sealant, not an adhesive. Surface must extremely clean and air bubbles must be worked out by using a serpentine type motion during application.
