What to clean with before Eturnabond

[wvabeer]

I have my 4 inch wide tape. I hear acetone,laquir thinner, enamel reducer, What is the best to use to prep before I stick this stuff down.

Acetone. I did every inch of my roof earlier in the year... acetone was the easiest to clean with. All sticking well at this point.

[MountaineerStreamer]

X2 on the acetone. Clean, no residue, etc

[92landyacht]

x3 on acetone. Wear gloves.

Make sure that the outside temps are within spec before you put it down.

If PO used ANY silicone calk then make sure it's all gone before you use the acetone.

If you find it's not sticking well after you've applied pressure, then it's not clean enough. That stuff sticks and can not be pulled off once pressed down.

[wvabeer]

Well how did I do?

[AtomicNo13]

No more leaks forever now...

Ya done good.

Enjoy!

I ran out of tape. I wanted to do the fridge and power vents. Will do at a later date.

[92landyacht]

Looks just like mine. Good job. The only difference is I used gray tape for the last foot at each side of the end caps. I started with white, but didn't like the white tape contrasting against the gray corner rounds as it came down the sides. The top didn't matter since you can't see it.

[wvabeer]

Darn I didn't know they had gray tape

[lonestranger]

How much Acetone did you use to do the seams? I know its kinda asking how long is a piece of string, But wondered "ballpark" how much to buy. also, how many feet are in a roll of the tape? I need to do a 36' LY. Lastly, what is best to use on the rest of the roof/ if anything! Appreciate any help or advice. Thanks in advance.

You won't need any more then a quart. I wish I would have bought 3 50 foot rolls.

I thank you again for the quick reply (and the insight!

PS: What, if anything, is best to cover/service the rest of the roof? Any coating etc.

Thanks again

I used a strong soap with a push broom to wash the roof first. I am going to use a rv cover after I'm sure all my leaks are fixed.

I've been thinking of coating the roof with EPDM Coatings Liquid Roof. My fiberglass roof is beginning to break down. When I sweep the roof I get a cloud of sparkling glass floating around for a few minutes. Figure a coat of liquid EPDM would add a level of protection and maybe slightly dampen the sound of rain on the roof.

You may want to check this out. I ran into this outfit at the Tampa RV show who is doing a roof treatment using a ceramic roof coating like they used on the space shuttle tiles. You may have noticed it on some school buses.

The place was:

And I think the product they use can be found here:

Elastomeric Waterproofing Insulating Ceramic Roof Coatings, Sealers, Metallic Finishes and Clears

[92landyacht]

Personally I'd prefer a product that was specifically designed to bond to fiberglass with no priming required. None of the coatings above state that they are designed to cover over fiberglass. Not saying that they wont work, I'm just saying that I'd prefer a product that states it's usable over the material I'm planning to coat and ideally was designed for RV use.

EPDM Coatings has two products. Liquid Roof is for RVs while Liquid Rubber is for all other applications. When I contact EPDM Coatings about the difference they said that the two products are virtually the same but the Liquid Roof’s cost was higher to cover the warranty for RV usage. Many I’ve spoken with have used the Liquid Rubber with great results. EPDM over fiberglass should last for years. They even have a FAQ about how to bond it to Eternabond tape.

This product does list it also for fiberglass..with a primer.

I still prefer a product that doesn't require a primer for it to bond to the roofing material. I also don't like products that require more then one application (primer + 2 coats roofing material = 3 coats according to thier application method). Cost wise it's not as attractive as it seems because of the cost of roof coating plus the primer. I also don't care for a product that limits the amount of ponding allowed. The EPDM rubber is designed to be used as a sealant for landscape pond bottoms. That says something about the sealing capability.

Like I said... It may be just fine to use Permakote and may last a lifetime as well. I just don't want to have to spend the money and work 3 times as hard to get the same results.

What ever you decide to do, the key is the preparation of the old fiberglass roof before painting. Here is a good, brief 6 step description:

How to Prepare Fiberglass to Paint | eHow.com

I'm sure the product you pick will have recommendations for surface preparation.

Good luck with the project and keep us posted.
