Ziollo RV Roof Lap Sealant

Ziollo RV Roof Lap Sealant is a self-leveling, solvent-free EPDM-compatible caulk that seals seams, vents and edges on motorhome, trailer and camper roofs.

Whether you're prepping for a cross-country trip or patching a weekend rig, this white, self-leveling lap sealant is formulated to bond to EPDM rubber, TPO, metal and fiberglass and remain flexible across temperature swings. It flows into fasteners, seams, and around fixtures for a neat bead and long-lasting weather resistance without solvent fumes or complicated surface prep.

How will this sealant stop leaks on an RV roof?

The product is designed to form a durable, waterproof barrier that adheres to typical RV roofing materials. Its self-leveling chemistry fills gaps and settles neatly so there are no trapped air pockets that cause failures.

• Adheres to EPDM, TPO, metal and fiberglass for secure bonds
• Flows into seams and around vents to fill irregular gaps
• Stays flexible to accommodate roof movement and temperature changes
• White finish reflects sunlight and blends with many roof surfaces

How easy is it to apply if I've never caulked a roof before?

Application is straightforward: cut the nozzle, place in a standard caulking gun, and apply. The self-leveling formula reduces tooling needs—once placed it smooths itself into seams, so novice users achieve tidy results with minimal effort.

• Comes in 10 oz tubes that fit common caulk guns
• No extensive priming or sanding required for most surfaces
• Self-leveling action minimizes finishing and cleanup time
• Non-solvent formula is safer to use around people and pets

How long will one tube last and how durable is the repair?

Each 10 oz tube covers roughly 25 linear feet when applied in typical lap-seal thickness. The compound is formulated to resist UV, temperature cycling and road vibration, so repairs have longevity compared with standard temporary caulks.

• Approximate coverage: 25 linear feet per 10 oz tube
• Engineered for UV resistance and thermal flexibility
• Adhesion that resists cracking and shrinkage over time
• Suitable for long-term maintenance rather than quick fixes

Is this safe to use around my family, pets and campsite?

The sealant is formulated without harsh solvents, minimizing fumes and reducing the need for respirators or evacuation during application. That makes it a practical choice for homeowners and RVers who prefer safer products for close-quarters work.

• Solvent-free formulation reduces strong odors and VOC exposure
• Safe to apply outdoors around people and animals when used as directed
• No special disposal or hazmat precautions required for typical use
• White color reduces heat absorption on exposed roofs

Who is this for? Ziollo RV Roof Lap Sealant is aimed at RV owners, DIY maintenance enthusiasts, and professional techs who need a reliable, flexible seal for rubber and mixed-material roofs. It suits those who want a product that flows into seams for a clean finish, resists weather and UV, and avoids solvent-related safety concerns—ideal for camper repairs, vent flashing, lap sealing and ongoing roof maintenance.
