Stop RV Skylight Leaks with These Pro Videos
A leaking skylight is one of the most common water-entry points in any rig. The constant exposure to UV rays, temperature swings, and road vibration inevitably degrades the original factory seals. Ignoring the initial signs of failure is the biggest mistake you can make.
The best overview videos don’t just show a perfect, clean installation; they show the reality of the job. Look for tutorials that demonstrate how to diagnose the leak’s source accurately. Is it a crack in the dome itself or a failure in the sealant around the flange? A good video will walk you through inspecting the old sealant for cracks and gaps before you even pick up a tool.
Ultimately, these videos empower you to differentiate between a simple reseal and a full replacement. They provide a visual roadmap, showing you the tools, the timeline, and the potential pitfalls of the project. This knowledge is the foundation for a successful, cost-effective DIY repair.
Master Dicor Lap Sealant for a Watertight Seal
Seal your RV roof with Dicor Self-Leveling Lap Sealant. Its self-leveling formula ensures easy, smooth application and creates a secure, sun-ray stabilized seal compatible with various roofing materials.
Dicor Lap Sealant is the industry standard for sealing horizontal RV roof surfaces for a reason. Its self-leveling properties create a smooth, seamless seal that gravity pulls into every crack and crevice. But applying it correctly is an art that video tutorials excel at teaching.
A high-quality tutorial will emphasize the importance of cleaning the old surface and applying a consistent, generous bead. Watch for demonstrations on how to "tool" the sealant, or rather, why you shouldn’t over-tool it; its self-leveling nature does most of the work. The video should also clearly differentiate between the self-leveling (501LSW) and non-leveling (551LSW) versions, ensuring you use the right one for the job.
Pay close attention to videos that discuss curing times and temperature considerations. Applying lap sealant in cold weather or when rain is imminent can lead to a failed seal. The best tutorials will show you what properly cured Dicor looks like and how to inspect your work after 24-48 hours to ensure a permanent, watertight bond.
Your Leisure Coachworks Dome Replacement Guide
Sometimes, a simple reseal isn’t enough. If your skylight dome is cracked, yellowed, or brittle, it’s time for a full replacement. This job seems intimidating, but it’s entirely manageable with the right visual guidance, and videos from channels like Leisure Coachworks are invaluable.
An effective replacement tutorial breaks the process down into clear, sequential steps. It starts with the most critical part: measuring your existing dome and flange correctly to ensure you order the right replacement part. It then moves to the careful process of removing the old, stubborn sealant and fasteners without damaging your roof membrane.
The best guides for this task show the re-installation in detail. This includes applying butyl tape to the flange, setting the new dome, and tightening the screws in the proper pattern to create an even seal. Finally, they’ll demonstrate the final, crucial step of applying Dicor lap sealant over the screws and flange edge for a durable, double-protected finish.
Seal RV, trailer, and window joints quickly and easily with Dicor Butyl Seal Tape. This 1/8" x 3/4" x 30' roll provides a strong, flexible, and permanent seal on any smooth or irregular surface.
Fix Interior Drips with Eternabond RoofSeal Tape
EternaBond RoofSeal tape creates a durable, waterproof seal on roofs, RVs, and more. Its MicroSealant technology bonds to various surfaces, offering UV resistance and eliminating the need for extra sealants.
For a fast, effective, and incredibly durable repair, nothing beats Eternabond tape. This isn’t just tape; it’s a micro-sealant on a roll that creates a permanent, flexible seal. It’s an excellent solution for sealing a cracked dome as a temporary fix or for reinforcing the entire flange as a primary seal.
A good Eternabond video tutorial will spend significant time on surface preparation. The tape’s adhesive is incredibly strong, but it requires a perfectly clean, dry surface to bond properly. Look for demonstrations using an appropriate cleaner and showing the removal of all old silicone or sealant residue.
The most crucial technique a video can show is the application of pressure. Eternabond is activated by pressure, not just contact. A quality tutorial will show the use of a small, hard roller to firmly press the tape, ensuring the micro-sealant bonds completely with the roof surface. Skipping this step is the number one reason for an Eternabond application to fail.
Get a Flexible Bond with Geocel Pro FlexRV
Seal tight with Geocel Pro Flex RV Sealant. Its flexible, crack-resistant formula offers excellent adhesion, even on damp surfaces, and withstands UV exposure.
While Dicor is king on the roof, it’s not meant for vertical surfaces. That’s where a high-performance sealant like Geocel Pro FlexRV comes in. Its incredible flexibility and adhesion make it perfect for sealing the vertical sides of a skylight curb or other areas where a non-sag sealant is required.
Look for video tutorials that highlight the differences between Pro FlexRV and standard silicone. Pro FlexRV is designed to handle the intense movement and vibration an RV experiences. The video should demonstrate how to lay a clean, consistent bead and, most importantly, how to tool it for a professional, waterproof finish.
A key benefit shown in tutorials is its all-weather application. Unlike many sealants, Pro FlexRV can be applied to damp surfaces and in a wider range of temperatures. This makes it a fantastic product for emergency repairs on the road, a scenario that practical video guides will often address.
Prep Surfaces Correctly with 3M Adhesive Cleaner
Easily remove sticky adhesive residue from painted surfaces, vinyl, and fabric with this gentle, general-purpose cleaner. Ideal for auto repair and detailing, it softens and wipes away residue, keeping vehicles clean throughout the repair process.
The best sealant in the world will fail if it’s applied to a dirty surface. This is a non-negotiable truth of RV repair, and it’s why understanding proper surface prep is so critical. A dedicated tutorial on using a product like 3M Adhesive Cleaner is worth its weight in gold.
A proper instructional video will show the process, not just the product. It will demonstrate how to safely remove old, chunky sealant with a plastic scraper first. Then, it will show the correct application of the solvent to break down the thin, stubborn residue that remains, wiping it away completely.
Most importantly, these videos teach safety and material compatibility. They’ll remind you to use gloves, ensure proper ventilation, and to test the cleaner on a small, inconspicuous area first. They prove that the 15 minutes spent on meticulous prep saves you from having to do the entire job over again in six months.
Your Full Reseal Using Alpha Systems Sealants
Not all RV roofs are the same, and using the wrong sealant can be a costly mistake. If your rig has a TPO roof, you need to use a compatible system, and Alpha Systems is a leading manufacturer. Using Dicor on some TPO roofs can cause the membrane to swell and fail over time.
A tutorial focused on Alpha Systems products will start by helping you identify your roof material. It will then walk you through their specific, system-based approach to sealing. This often involves a primer or cleaner followed by their 1021 Self-Leveling Sealant, which is chemically engineered to bond with TPO.
The key takeaway from these videos is the concept of system compatibility. A good tutorial will explain that the products are designed to work together for a permanent, warrantied repair. This prevents you from making a critical error that could void your roof warranty or lead to premature failure, turning a simple fix into a major headache.
