The Importance of RV Sealant

Good seals are important for the long-term health of your RV. Sealant is used in many locations to keep weather and dirt out, including around windows, vents, seams, and more. Since an RV is meant to travel down the road, the body will be constantly shifting and moving. Don’t let the elements invade your RV and start causing damage. Keep in mind that even the best seals can wear over time, so be sure to regularly inspect your RV and reapply sealant as needed.

Why Use a Silicone / Polyurethane Blend?

Our Life Seal RV silicone sealant is a blend of silicone and polyurethane. This mixture offers RV owners a number of performance advantages, including:

  • Fast curing times
  • Low odor
  • High adhesion to many materials
  • Non-sagging
  • Non-corrosive
  • Non-yellowing

If you have been let down by other RV sealant products, RV by LIFE’s Life Seal is sure to impress with its high-quality properties.

Three Quick Tips

Applying RV sealant is a simple job. These tips should help you get it just right:

  • Clean your RV. One of the most important steps in the process is to properly clean the area of any sealant residue, debris and grease before applying your new sealant product.
  • Adjust your thickness. When you are repairing a small crack in the old seal (check for compatibility first), you won’t need to use nearly as much product as when you are creating a new seal where the old material is gone completely. Adjust as you go to use just the right amount of Life Seal.
  • Always be safe. When working up high on your RV, take all necessary safety precautions and never put yourself in a position that feels risky.
