Replacing your RV shower skylight's inner dome might seem daunting, but with the right approach and tools, it's a manageable DIY project. A cracked or damaged dome not only compromises the aesthetic appeal of your RV but also impacts its weatherproofing. This comprehensive guide provides a step-by-step process for a successful replacement, ensuring a leak-free and aesthetically pleasing shower experience.
Assessing the Damage and Gathering Supplies
Before you begin, carefully assess the extent of the damage to your inner dome. A small crack might be repairable with specialized sealant, but a significant crack or shattering necessitates a complete replacement. Once you've determined that replacement is necessary, gather the following supplies:
- Replacement Inner Dome: Ensure you purchase a dome that's the exact size and model to match your existing skylight. Note the manufacturer and model number of your existing skylight for accurate ordering.
- Caulk (RV-safe): Select a high-quality, weatherproof sealant specifically designed for RV applications. Dicor is a popular choice.
- Putty Knife or Plastic Scraper: This will help remove old caulk.
- Cleaning Supplies: Use a cleaner appropriate for the material of your skylight frame (e.g., glass cleaner for glass frames).
- Safety Glasses: Protect your eyes from debris during removal and installation.
- Gloves: Protect your hands.
- Ladder or Sturdy Step Stool: For safe access to the skylight.
Step-by-Step Replacement Process
1. Preparation:
- Clean the Area: Thoroughly clean the skylight frame and the surrounding area to ensure a proper seal. Remove any old caulk with a putty knife or plastic scraper. Be gentle to avoid damaging the frame.
- Safety First: Put on your safety glasses and gloves.
2. Removing the Damaged Dome:
- Locate Fasteners: Carefully examine the inner dome to identify how it's attached to the frame. Most domes are secured with screws or clips.
- Remove Fasteners: Use the appropriate tool (screwdriver or pliers) to carefully remove the fasteners. Work slowly and methodically to avoid damaging the frame.
- Separate the Dome: Once the fasteners are removed, gently separate the damaged inner dome from the frame.
3. Installing the New Dome:
- Clean the Frame: Clean the skylight frame again to ensure a clean surface for the new sealant.
- Apply Sealant: Apply a generous bead of RV-safe caulk around the perimeter of the skylight frame where the new dome will sit. Ensure the bead is even and continuous.
- Position the New Dome: Carefully align the new inner dome with the frame, ensuring it sits evenly.
- Secure the Dome: Replace the fasteners, tightening them securely but avoiding over-tightening.
4. Final Steps:
- Inspect the Seal: Inspect the sealant around the perimeter of the new dome to ensure there are no gaps or imperfections.
- Clean Up: Clean up any excess caulk that may have squeezed out during installation. Allow the caulk to cure completely as per the manufacturer's instructions before using the shower.
Troubleshooting and Tips
- Difficult Removal: If the old dome is stubbornly stuck, consider using a heat gun (on a low setting) to gently soften the old caulk. However, exercise extreme caution to avoid damaging the frame or causing burns.
- Dome Size: Double-check the dimensions of your replacement dome before purchasing to ensure a perfect fit.
- Caulk Choice: Using an inappropriate caulk can lead to leaks. Choose a high-quality, RV-specific sealant.
Maintaining Your RV Shower Skylight
Regular maintenance can extend the life of your RV shower skylight and prevent costly repairs. Periodically inspect the dome for cracks or damage and clean the skylight to maintain its clarity and prevent buildup. By following these steps, you can keep your RV's shower functioning optimally and looking its best. Remember, always consult your RV's owner's manual for specific instructions and recommendations.
