Ok…. here are some pics of our project we just finished on our motorhome!

On our 1996 Safari Serengeti, our fiberglass roof can be known to get tiny microscopic cracks and fissures after 10 years of age…. resulting in potential leaks! The type of roof we have is known as Filon, a textured sheet of fiberglass that is rolled out on top of the substructure and left unattached except around the edges, allowing for expansion and contraction.

So the guys on the Safari list with rigs the same vintage of ours are coating with a special elastomeric coating made for fiberglass…. (similar to Kool-Seal, but we had to get the formula made for fiberglass)

There are alot of different brands of elastomeric coatings out there. You have to find one that works for your type of roof. (ours was fiberglass in this case) Read the cans and find something with a longer warranty life.   This one said 7 years if you do two coats.

(DON'T use that fibered roof coating stuff that is used for mobile homes, it's very thick black tarry stuff that dries silver– I did that on my old motorhome in the 90's … not good, and not the right product for a flexing moving structure)

Here is the brand we bought, called SealBest at Menards, a mid-west home improvement chain.

First we scrubbed the roof good with TSP and let it dry…  Whew, I sure don't like heights, but with adrenaline rushing and heart pounding, I joined him up there to work fast as a team effort and get it done! We lined the sides of the roof where it meets the painted sides with blue painter's tape.

The next day, we started with the coating.  I crawled around on my hands and knees, hand brushing liberal amounts of the coating around all the vents, air conditioners, skylight and antennas. Keeping a wet edge, then Steveio rolled the remaining parts with a thick napped roller on a long handle. He got to stand, I was too scared to stand!

We used almost a full gallon with the first coat. This is a wide body motorhome almost 40 feet long. We used up the rest of the first gallon and part of the second gallon the next day, rolling it on as thick as we can. The warranty reads that you must put on 2 coats to comply with the 7 year warranty.  On the third day, Steveio got up there and rolling the rest of the second gallon for a third coat!

Here are all the pics in order from start to finish: 

We put all the maxi-vent covers back on, pulled the blue tape off and it sure came out nice….
