NE Reg Dir Retired
Last week when I was ready to pack to go away for the weekend, I was set back when I found a wet spot on the carpeted steps under the closed bedroom slideout. We had one trip on the rig and we had a leak. We went away for the weekend and when we returned home on Sunday it rained later in the day. John went out to the camper and came in soaked. He said come with me you've got to see this. We went back to the camper and he told me to watch the water when it runs down the slide out. It would run down the side and disappear when it hit the caulking above the lower trim cap. We pulled the old caulk off and cleaned the area. He has used a professional grade caulking (NPC Solar Seal #900) at work for windows and doors on the schools. He contacted the company and their response was "if it were my trailer, I would use this product"! They also stated that it was ok to use on fiberglass Gel-Coat and suggested a 3/8 inch application for best performance. This caulk is not available at box home centers. You can contact npc@npcsealants.com for help with this product.
We obtained the caulk and did the job on Thursday. I just took the attaced pictures and watched the rain roll down the side of the slideout, hit the caulk, roll over it and continue down the bottom trim cap. I went in the trailer and there was no water anywhere. I see a lot of posts on slide leaks and would suggest you put an intense inspection to all caulking before anything else. We're repaired, no hassle, no hauling to the dealer for warranty work, no damage, no big deal! It took about an hour to fix.
