Mike Kernagis, Service Manager at Palomino RV, shows how to properly maintain camper seals.  Get your caulk guns ready.

Use Caulking Gun Spread Geocel Sealant Evenly

Today’s article is about how to maintain your camper’s seals.  Maintaining camper seals is one of the top five questions we get at TCM.  To help us get a definitive answer on this important issue we talked to Mike Kernagis, Service Manager at Palomino RV.

Teaching Us How To Caulk A Camper

Tom Noirot, Service Technican and Mike Kernagis, Service Manager at Palomino RV

We also met Tom Noirot, Service Technician, who brought in a Palomino 8801 hard side camper and a Palomino Bronco 1251 for our seal maintenance article.  Tom has been in the RV service industry for seventeen years and Mike has seven years of RV service experience.  They have sealed hundreds, if not thousands of truck campers.

“Constant inspection of the seals is the key to keeping water out and your RV looking like new.”

When Should You Caulk Your Camper?

Mike recommends that you caulk your camper twice a year; once after you de-winterize and once right when you are winterizing in the late fall.  Mike also recommends two different sealants for truck campers.

Dicor For Roof, Geocel For Sides

For FRP or rubber camper roofs, Mike uses Dicor roof sealant.  Dicor is the industry choice for sealing RV roofs because it is a self-leveling sealant.

Maintaining Camper Seals with Geocel RV sealant

For the remaining exterior of your camper, Mike uses Geocel MHRV (Motorhome/RV) heavy duty sealant.  Geocel has a high UV rating, which makes it an excellent choice for truck campers.

Dicor and Geocel are available at most RV supply stores and many hardware stores.  Mike does not recommend using silicone based sealants unless it is an emergency, such as sealing a leak in a rain storm.

How To Caulk Your Camper

1. With mild soap and water, wash your entire camper.  If you have a pop-up camper, wash your camper with the pop-up closed.  If your camper is not clean, you are not going to see the seals as easily.

Identify Breaks In Sealant

2. Inspect your entire camper for seals that are cracked or coming away from the fixtures (above).  Mike recommends focusing in particular where fixtures meet the roof or side walls.

Citrus Cleaner To Get Seals Clean

3. Remove the old caulk by spraying the caulked areas with a strong citrus cleaner (above).  Mike recommends Goo Gone because it is a strong citrus cleaner that works well.

Get Old Caulk Off First

4. Use a “putty buddy” or other plastic scraper to remove the old caulk.  For easy removal, use a thick, high quality scraper (above).
