Non-sag caulking is a thicker sealant that is ideal for vertical and overhead applications in RVs where a non-drip, stable application is required. This type of caulking is resistant to slumping or sagging during the curing process, allowing it to maintain its shape when applied to sidewalls, around windows, doors, and other vertical joints. Its robust formulation ensures that the sealant stays in place, providing a durable barrier against weather, moisture, and air ingress, thus protecting the RV from water damage and improving energy efficiency.
