Got an older Mobile Scout that I am going to permenantly park at my deer lease and use just for hunting season. Its got a metal roof that has some pretty bad leaks. I do not want to put much money into this thing as it is gonna be in the woods all year. I have have several RV shops in my area tell me that the way to go is to use the Geocel Instant RV Roof repair, or the Geocel All Purpose brushable Roof Sealant. They say this stuff is worth its weight in gold. The reviews on it are great. I dont mind spending a couple hundred on this stuff if it will help stop the leaks. I would use tar, but I cant get on top of the camper to spread it. The Geocel stuff says it is brushable. Has anyone used this stuff ? Give me your input. All advice will be appreciated !!! Have a great day yall !!
After a thorough cleaning, joints, crack, and all, how about sealing the joints and cracks with polyurethane sealant. If you want a coating on top of that, try Kool Seal. I've used the white and would do so again. Cheap and effective.
How will the new roof coating stick to the roof without first cleaning the old roof, and giving it a chance to stick to something other than the dirt that will come off with the first wind.
When I was working on my old EPDM roof, there where a couple of leaking areas that needed attention before the Herculiner would arrive in the mail. So I actually used contact cement and aluminum foil to apply some patches to the cracked sections of roof, thinking I would be able to remove them later, when applying the Herculiner. The aluminum patchs stuck well, and are now under the Herculiner, so are part of the roof forever.
You should use a stiff brush or perhaps a broom, from a 8' ladder, to wash the roof well before applying something. The two part coating will work fine, 2 gallons should provide a nice thick coating, and can be moved around with a paint roller on a 4' pole, from the same 8' ladder beside the RV. Pour it on about a foot from the sidewall, and then spread it around with the paint roller.
http://forums.woodalls.com/Index.cfm/fuseaction/thread/tid/24993453.cfm is the page I wrote about a year ago about my Herculiner roof. There is a link for both Herculiner and the two part roof coating. The video on the link also shows how easy it is to apply, and just about anyone can do it. My suggestion is get around all the roof vents with a paint brush first, then each vent near the sidewall (before the roof becomes sticky with fresh coating) then do the middle sections.
One guy coated his Bounder with a 1 gallon container mixed up on day 1 after cleaning the roof, he coated all the vents and seams with the first gallon. Next day mixed up a 5 gallon pail, and coated the roof and all seams again! Went well, but 1/2 way through thought it was going on to thick, then at 3/4 done realized it was to thin and had about a gallon left over on a 38' Bounder motorhome. Had plenty to go over all the seams again!
IT should work well.
I would not recommend any one part coating, I used one on my camper with a metal roof, and it dissolved when exposed to standing water in Washington.
Herculiner is sort of 1 part, you apply it straight out of the can, but the solvent evaporates and leaves behind the plastic like coating, that is thick, slip resistant, and going to last a long time!
I know it is expensive, but a place out of north Florida, rvroof.com has something that looks like a good product. It seems to be like Line-X as it is a two part epoxy which means it cures, not dries. However, it uses polyurethane, so it is a lot more flexible than the Line-X stuff.
I don't know if this place is one of a kind, or if someone has a competing two-part product nearer your neck of the woods. I wish someone near central Texas had this, because it would definitely solve RV roof leak problems until a branch or something like that cut the roof. I'd also consider this even with a fiberglass/metal roof just because it would add a layer of insulation.
Spraying Line-X on the roof may not do the job -- from what I guess, it likely is too brittle.
Anyone know of similar products that are epoxy, two-part based, preferably sprayed on similar to what rvroof.com has?
A trailer for a deer camp? Don't even mess with the roof- throw up a pole barn over it- that way the money isn't in the trailer, and - sight unseen- I can almost guaranty it will take a bunch of work to seal the trailer, and it will still leak, unless you spend some labor on sealing it up.
mlts: I live near the rvroof.com place you mentioned and will soon be having their product applied to my Class C RV. If you haven't found it already, you might search for Rhino products which I believe offers similar treatment. Maybe they have someone closer to your area.
I just sealed a '71 Starcraft aluminum roof. Previous owners had spread tar, RTV silicone, aluminized roof coating, elastomeric paint, and who knows what else.
I ended up sealing all of the joints, vents, pipes, and anything that looked like it would leak with Eternabond tape. I followed that with two coats of white Elastomeric paint. Cleaning off the previous gunk was the biggest part of the job. I would suggest you don't use tar, it won't seal anything worth squat.
The Herculiner or Rhino liner products are a do-it-once covering. It might depend on what you're willing to spend to fix the problem.
