FAQ Section

Q1: How often should I apply seam sealer to my pop up camper?
A: It depends on usage and product. For fabric seams, inspect them annually. If you notice any signs of wear, stickiness, or water ingress, it’s time to reapply. For roof coatings, products like Ziollo and Liquid Rubber offer 10-year warranties, but regular inspection is still key. The best seam sealer for pop up camper maintenance will require periodic checks.

Q2: Can I use seam sealer on both fabric and hard-top pop up camper roofs?
A: Not all seam sealers are universal. Products like GEAR AID Seam Grip FC or WP are ideal for fabric. For hard-top roofs, especially around vents or larger areas, you’ll need specialized RV roof sealants like WELLUCK RV Roof Tape, Ziollo, Liquid Rubber, or the 8 Pack Self-Leveling Sealant, which are designed for materials like EPDM, TPO, metal, and fiberglass.

Q3: What’s the best way to prepare a surface before applying seam sealer?
A: Preparation is crucial for a lasting seal. Always clean the area thoroughly, removing any dirt, old sealant residue, grease, or loose particles. A clean, dry surface ensures proper adhesion. For fabric, mild soap and water followed by a complete dry is usually sufficient. For RV roofs, specific cleaners (like those offered by Ziollo or Liquid Rubber) are recommended.

Q4: Is there a difference between seam sealer and lap sealant for RVs?
A: Yes, there is. Seam sealer (like GEAR AID products) is typically for sealing fabric seams where two pieces of material are stitched together. Lap sealant (like the 8 Pack Self-Leveling Sealant) is a heavier-duty product designed for rigid RV roofs, used to seal the “laps” or overlaps of materials, around vents, and other roof penetrations. Lap sealants are often self-leveling.

Q5: Can I apply seam sealer in cold weather?
A: Most seam sealers and roof coatings have specific temperature requirements for application and curing. Applying in very cold temperatures can affect adhesion and curing time, potentially leading to a less effective seal. Always check the product’s instructions for recommended temperature ranges. For example, Liquid Rubber suggests 50°F-90°F.

Q6: What if my pop up camper’s fabric is sticky or flaking?
A: This usually indicates the original polyurethane (PU) coating is degrading. For this specific problem, products like GEAR AID Seam Grip TF Tent Fabric Sealer are designed to reapply that waterproof coating, restoring the fabric’s integrity without needing to seal individual seams. This can be a game-changer for older pop up tent sections.

Q7: How much seam sealer do I need for my pop up camper?
A: This depends entirely on the product and the area you’re covering. Small tubes of seam sealer might cover 10-60 feet of seams. Liquid roof coatings are measured in square feet per gallon (e.g., 50 sq ft per gallon). Always estimate your coverage needs and check the product’s specifications before purchasing to ensure you have enough of the best seam sealer for pop up camper repairs.
