Water Damage Repair

I recently purchased a 2005 Thor Mandalay that was a theft recovery. This coach sat from 2008 to 2015 and only has 8000 miles. I has a Cummins ISL engine. I picked it up from auction and took my father in law who is a Frieghtliner mechanic with over 30 years experience. I drove it 400 miles back to Dallas without a problem and it drove great. I have now started the repairs and as you can imagine after sitting for 7 years where do you begin. I powered washed the roof and sealed it with Dicor. I have also replaced the sunroof in the bathroom. I tend to take on big projects and am competent in most auto repairs and home remodels. There is water damage in the bedroom from the sunroof and the ceiling also has water damage in several areas. My questions are more "how to" questions. The ceiling is styrofoam under the luan and vinyl lined foam. The floor is OSB board with styrofoam underneath. I also noticed metal bands the cross the ceiling for mounting things to the ceiling i presume. The OSB is glued down to the styrofoam is that the method for mounting the floor to the cross members and styrofoam? What type of adhesive is used for mounting the floor? Are there any fasteners used. With Thor have the metal bands that cross the ceiling? How do you eat an elephant? One bite at a time. I am starting the demo but I notice that my sealing the roof has not worked completely as "it flooding down in Texas" and I have sprung a few leaks. Any help with adhering the floor and luan to the ceiling would be greatly appreciated. I want to follow the same method that was used at the factory since 10 years later in areas where there is no water damage I have great adhesion. I am doing a full remodel including porcelain tile and new furniture in addition to wall treatments. Many more post to follow.

I had a friend that would refurbish yachts when I lived in California he became a great inspiration of possibility. This coach was complete but damage from neglect. I can see why routine inspection and maintenance is critical. More demo work today

I love following restorations like this!

Could you do us a favor? If you have Win7, navigate to the directory where the pictures are, right click on any picture. It will give you the option to 'Rotate' the picture. Then when you upload here, it's in the right orientation.

My necks too stiff today for the pics you posted.

Thanks! Good luck on the project.

Replaced half of my bedroom floor back in the spring. It was half inch OSB screwed down to metal joists. Had the 3/4 styrofoam , but wasn't glued to it. It was screwed into those steel joists and possibly Liquid nailed. Not to sure. Part of floor was pretty much mushed out with water damage through the winter. Real surprise when I started to take up carpet to replace with vinyl. Had roof resealed/seamed and got it fixed up really nice.

Now someone else is enjoying it. It was a Class C. Took a couple of trips over the summer and got back from NE and decided to sell it . Went in one day. Thinking of a Class B for next one. Good experience getting into one and redoing it.

Best of luck to you! Welcome to the forum. Blessed travels to you... that is after you get her going

this floor is definitely glued to both the styrofoam and the steel joists. I have noticed a few anchor bolts spread out around the coach. I am slowly dissembling the coach interior. I spent a couple of days sealing the roof with lots of dicor and now with the deluge of rain I still have leaks a few are around the slide outs. One is around is a drip around the new sky light i just installed. One is on an outside wall beside the shower, maybe from an awning mount it is the only other place where water could be coming from. I will figure it out. The bedroom slide has a hydraulic / cable slide. The floor under the slide frame which is boxed in under the bed platform has water damaged. I will have to jack the slide up out side to brace the slide and figure out a way to remove the plywood under the frame, scrape the styrofoam clean and re attach the frame to the floor. I can't wait to get to putting it back together. New everything, LED lighting, Furniture, Mattress, removed the curio cabinet and replacing it with a pantry to make it functional. Will tile the floor porcelain high gloss tile and also put heating under the tile from

I spoke with Lynn Habegger from Habegger Flooring Distributors, Inc.

His father was the first to engineer a complete ceramic tile floor in a class A motorcoach. He gave the the recommendation for tile adhesive and grout. I will also include the vendors I use for anyone ambitious enough to do a high end remodel.

For now it is all the prep to get to the fun part.
